A Smyrna, Delaware research storefront with public per-strength list prices and a COA library whose Freedom Diagnostics, Janoshik, and Chromate certificates can be checked at those laboratories.
Honest Peptide lists research-only vials with the strength on the size option, including house names GLP-1 S for semaglutide, GLP-2 TZ for tirzepatide, and GLP-3 R for retatrutide. Blend sizes such as GLOW 10/10/50 mg are the component amounts; the comparable vial total is their sum. The public COA library includes current and older certificates. Bacteriostatic water and acetic acid stay off the vial comparison.
Testing transparency: Public COA library with Janoshik, Freedom Diagnostics, and Chromate verification. The public COA library publishes certificate images. Freedom Diagnostics search codes, Janoshik task-and-key reports, and Chromate job-and-access reports resolve at those laboratories under Honest Peptide. A matched certificate documents the tested sample. It does not cover every vial or an unlisted safety panel. 2 older HPLC images are Vanguard Laboratory certificates without a public lookup code.

Open profile A Sheridan, Wyoming research storefront (Kylo Labs LLC) with public per-strength list prices and a COA library whose Freedom Diagnostics search codes resolve under KYLO Research Labs LLC.
Kylo Peptides lists research-only vials with a strength on the variation or the product SKU, including house names GLP 3 (RT) for retatrutide and GLP 2 (TZ) for tirzepatide. The public COA library includes Freedom Diagnostics certificates that can be checked at the laboratory. Multi-vial stacks, bacteriostatic water, and the lifetime membership stay off the vial comparison.
Testing transparency: Public Freedom Diagnostics certificate library with provider verification. Public /coa/ PDFs include Freedom Diagnostics search codes that resolve at the laboratory under KYLO Research Labs LLC. A matched certificate documents the tested sample. It does not cover every vial or an unlisted safety panel. The same page also links Janoshik and Vanguard reports.

Open profile A U.S.-only research storefront (Kalyx Labs, LLC) with publicly listed variation prices and a public library of Freedom Diagnostics certificates whose Search Codes resolve at the laboratory under the Kalyx Labs client name.
Kalyx Labs sells research-only compounds with per-strength prices, including single vials and 10-vial kits. Burn Blend is the retatrutide/tirzepatide blend and Wolverine Blend is the BPC-157/TB-500 blend. Certificate PDFs are publicly downloadable; PeptideBenchmark confirms Freedom Diagnostics Search Codes against the laboratory when the client field names Kalyx Labs. Product pages and the lab-reports browser ask for an account. Supplies, stacks, capsules, sprays, and non-peptide research chemicals stay outside the injectable vial board.
Testing transparency: Public Freedom Diagnostics certificate library with provider verification. Public certificate PDFs are Freedom Diagnostics documents whose Search Codes resolve at the laboratory’s public verification surface under the Kalyx Labs client name. Reports typically support identity, HPLC purity, and net content for the named sample. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel. Product pages and the lab-reports browser ask visitors to sign in.

Open profile A Michigan-identified public storefront with stock-aware variation pricing, live per-SKU sales, and a large current-and-historical multi-laboratory certificate registry.
ezPeps exposes a stock-aware public variation catalog and a structured multi-laboratory certificate registry. PeptideBenchmark keeps temporary sales, checkout-only coupons, first-order savings, payment incentives, rewards, shipping, and optional package protection in separate pricing lanes rather than mixing them into default ranked prices.
Testing transparency: Public multi-laboratory COA archive with exact provider verification. Exact provider-controlled routes support reports from Freedom Diagnostics, ILS Laboratories, Horizon Analytical, TrustPointe, and Kovera Labs. Deterministic Janoshik task/key routes remain source-linked when the provider challenges ordinary unattended verification, while a current row without a public source URL is recorded as an evidence gap rather than inferred. Panel coverage is shown per certificate rather than inherited across the archive.
Profile: ezpeps
Open profile A Sunrise, Florida storefront with a broad public catalog, stock-aware regular pricing, independently modeled sale and bundle lanes, and a deep public certificate library retaining current and historical documents.
Go Alpha Labs exposes 188 publicly listed catalog products, 74 comparable retail-vial offers, formal shipping and returns terms, and 274 distinct public certificate origins. PeptideBenchmark preserves regular prices as the base, models temporary per-product sales separately, and does not assume they stack with the bundle.
Testing transparency: Provider verification for 186 of 274 certificate origins. Every document linked from the public /coas/ library is byte-validated, fingerprinted, read for laboratory and panel context, and related to its published product context. Exact provider checks confirm 154 Freedom Diagnostics and 32 BioRegen reports. The remaining 88 origins stay preserved and source-linked without being mislabeled as failed, invalid, or independently verified.
Profile: go-alpha-labs
Open profile An Arizona-positioned public WooCommerce storefront with exact variation pricing, visible subscription and shipping terms, and a catalog-wide certificate library whose reports resolve independently at Freedom Diagnostics.
Unyx exposes 28 public product parents, 48 currently in-stock comparable vial offers, and 44 current Freedom Diagnostics certificates bound to exact strengths across 27 retail peptide product families. PeptideBenchmark uses one-time list prices by default, keeps subscription and first-order savings opt-in, and separates laboratory-reported identity, purity, and net content from vendor-stated safety badges.
Testing transparency: Catalog-wide Freedom Diagnostics reports with live provider verification. All 44 public library rows resolve under the UNYX Peptides client at Freedom Diagnostics, and every vendor-hosted copy matches its exact provider report. The linked reports support identity, HPLC/LC-MS purity, and net content. They do not support the storefront’s repeated sterility or endotoxin badges, and one product-family certificate is not treated as independent testing of every listed strength.
Profile: unyx-peptides
Open profile A Cary, North Carolina storefront with a public stock-aware catalog, an anonymous-cart discount that can be reproduced without an account, and a large multi-batch certificate library spanning current and retained historical records.
Oros Research exposes 80 catalog products and a large public multi-batch certificate library backed by Supabase-hosted PDFs. As of October 3, 2026, 232 certificate origins / 233 document relationships currently resolve, with no excluded documents. PeptideBenchmark models only in-stock, safely comparable offers, routes vials, ready sprays, and capsules to separate Pricing lanes, and keeps vendor-stated fields, document-extracted values, and provider verification separate.
Testing transparency: Current source-linked PDFs plus provider-linked batch reports. Refreshed October 3, 2026: certificate files resolve through stable coas-public PDF ids with short-lived signed storage redirects. Live discovery lists 232 certificate origins, with no excluded documents. By laboratory, the reviewed certificates break down as 135 Ethos Analytics, 92 Freedom Diagnostics and 5 Vanguard Labs. The retained evidence layer includes 81 provider-linked certificate origins confirmed through exact credentials; 152 entries remain validated vendor-hosted documents. PB does not transfer a provider-verification badge from an older document by lot alone, and prior Shopify CDN objects remain preserved as historical evidence.

Open profile A Denver-shipped public WooCommerce catalog with standing single-vial prices and a public certificate archive whose Kovera report codes resolve at the laboratory’s public verify lookup.
Vector Amino Labs exposes a public research-peptide catalog and a certificate-of-analysis page that pairs each current lot image with a laboratory report code. PeptideBenchmark ranks the regular per-vial list price and treats sitewide sale pricing as a separate observed lane.
Testing transparency: Public COA archive with Kovera Labs provider verification. The public archive publishes certificate images with Kovera Labs report codes that resolve at the laboratory’s public verify lookup, plus one ILS Laboratories card. Most current single-vial products have a matched certificate; kits, bac water, and non-peptide injectables are outside the peptide board. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A Houston-stated U.S. research storefront with openly listed cart prices and a public /coa archive of Freedom Diagnostics, ILS Laboratories, and Kovera Labs certificates that resolve at the issuing laboratories, with Freedom and ILS reports naming the Void Research client.
Void Research sells research-only singles, blends, and nasal sprays with cart prices on the public shop, including house codes GLP-2 TZ for tirzepatide and GLP-3 RT for retatrutide, plus GLOW, KLOW, and BPC/TB blends. The public /coa page publishes Freedom Diagnostics, ILS Laboratories, and Kovera Labs certificates per batch, keeping superseded reports alongside their replacements; PeptideBenchmark confirms printed Freedom Search Codes and the ILS portal verify route (token or printed Access Code) when the client field names Void Research, and Kovera KVR report codes at the laboratory’s public verify endpoint. Comparable nasal sprays appear in Ready sprays; reconstitution and support SKUs remain outside Pricing.
Testing transparency: Public COA archive with Freedom Diagnostics, ILS, and Kovera provider verification. The public /coa archive hosts Freedom Diagnostics, ILS Laboratories, and Kovera Labs Certificate-of-Analysis documents whose Search Codes, portal verify routes, or KVR report codes resolve at the issuing laboratory; Freedom and ILS reports name Void Research in the client field. Published certificates typically support identity, HPLC purity, and net content for the named sample; ILS and Kovera reports add endotoxin and, on covered batches, sterility, heavy-metals, and fentanyl-screen fields. A matched certificate documents the tested sample and does not endorse every vial or unlisted lot.
Profile: void-research
Open profile An independent research-peptide marketplace with openly listed multi-source kit prices and public /verify batch pages whose Freedom Diagnostics, Janoshik, and Bioviridian certificates resolve at the issuing laboratories.
Peptuvia is a multi-source research marketplace rather than a single manufacturer storefront: product pages list independent sources with per-potency kit prices, and fulfillment is vendor-stated to ship from regional warehouses or direct from the named source. House codes RT and TR map to retatrutide and tirzepatide on the pricing board. Public /verify/{code} pages publish Freedom Diagnostics Search Codes (Pept…), Janoshik Analytical reports normalized to exact tests/{task}_{key}, and Bioviridian Web Verification Codes (COA######) that PeptideBenchmark confirms at the laboratory. Some vendor-hosted /coa mirrors redact Freedom Search Codes or link dead Accumark PDFs, so those lots stay outside provider-verified evidence. Comparable oral peptide tablets and capsules appear in Capsules; vitamins and non-peptide support SKUs remain outside Pricing.
Testing transparency: Public /verify batch pages with Freedom, Janoshik, and Bioviridian provider verification. Batch pages under /verify publish Freedom Diagnostics Certificate-of-Analysis documents whose Search Codes resolve at the laboratory under Peptuvia-prefixed client names (for example Peptuvia - Sentinel), Janoshik Analytical reports live-verified at exact tests/{task}_{key} paths, and Bioviridian certificates whose COA###### codes resolve at bioviridians.com. Published certificates typically support identity and HPLC purity for the named marketplace batch and source; they do not endorse every warehouse listing or later lot on the same product page.

Open profile A U.S.-operated research storefront with openly listed single-vial and multipack prices and per-product Freedom Diagnostics certificates that resolve at the laboratory’s public lookup under the Endura client name.
Endura Peptides sells research-only singles and blends with prices on the product pages, including house codes GLP-2T for tirzepatide and GLP-3R for retatrutide, plus KLOW, BPC/TB, and Ipamorelin/CJC blends. Each catalog peptide links downloadable Freedom Diagnostics certificates; PeptideBenchmark confirms printed Search Codes against Freedom’s public index when the client field names Endura. Quantity multipacks and bacteriostatic water stay outside the retail single-vial board.
Testing transparency: Public product-page Freedom Diagnostics COAs with provider verification. Product pages host Freedom Diagnostics Certificate-of-Analysis PDFs whose Search Codes resolve at the laboratory’s public verification surface under the Endura client name. Reports typically support identity, HPLC purity, and net content for the named sample. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A Delaware-mailed U.S. research storefront with openly listed single-vial prices and a public COA Vault of Freedom Diagnostics certificates whose Arte* Search Codes resolve at the laboratory under client Artemyx Research.
Artemyx Research sells a compact research-only catalog with prices on the product pages, including house codes GLP-2T for tirzepatide and GLP-3R for retatrutide, plus KLOW, MOTS-c, and MT-1. The public COA Vault (linked as /coa/) publishes Freedom Diagnostics certificates; PeptideBenchmark confirms printed Search Codes against Freedom’s canonical report objects when the client field names Artemyx Research. Reconstitution solution stays outside the retail single-vial board.
Testing transparency: Public COA Vault with Freedom Diagnostics provider verification. The public COA Vault hosts Freedom Diagnostics Certificate-of-Analysis documents whose Arte* Search Codes resolve at the laboratory’s public verification surface under the Artemyx Research client name.

Open profile A U.S.-facing research storefront (validatedpeptides.com) with openly listed single-vial prices and a public certificate browser whose ILS Laboratories and Janoshik Analytical reports resolve at the issuing laboratories under the Validated Peptides client name — a different company from curated Verified Peptides.
Validated Peptides sells research-only singles and blends with milligram size options on the public catalog, including house codes GLP-1Sema, GLP-2Tirz, and GLP-3Reta for semaglutide, tirzepatide, and retatrutide, plus GLOW, KLOW, and Wolverine blends. The public /coa page and product pages expose downloadable third-party certificates; PeptideBenchmark confirms ILS Laboratories Access Codes at portal.ils-lab.com and exact Janoshik task/key routes at verify.janoshik.com when the client field names Validated Peptides. Bacteriostatic water stays outside the retail single-vial board.
Testing transparency: Public COA archive with ILS + Janoshik provider verification. The public certificate browser and product pages host third-party Certificate-of-Analysis PDFs. PeptideBenchmark confirms ILS Laboratories reports via Access Code → portal.ils-lab.com verify routes and Janoshik Analytical reports via exact verify.janoshik.com/tests/{task}_{key} routes under the Validated Peptides client name. Many ILS Full QC panels also cover endotoxin, sterility, heavy metals, and net content for the named sample. A matched certificate documents the tested sample and does not endorse every vial.

Open profile A U.S.-based research storefront (also styled EnhancedChem; legal entity Advanced Chems LLC) with openly listed single-vial prices, a public /coa/ Freedom Diagnostics archive under client Enhanced Chem, and additional product-page Janoshik certificate image scans.
Enhanced Chems sells research-only injectable vials with standing list prices on the product pages, including house codes GLP2 for tirzepatide and GLP-3 RT for retatrutide, plus GLOW, KLOW, and BPC/TB blends. The public /coa/ page publishes Freedom Diagnostics PDFs whose Search Codes resolve at the laboratory under client Enhanced Chem. Many product galleries also show Janoshik Analytical certificate scans; those published scans blank Task Number, Unique Key, and Client, so they remain vendor-hosted documents rather than independently re-checkable portal reports.
Testing transparency: Public COA archive with Freedom Diagnostics provider verification. The public /coa/ archive hosts Freedom Diagnostics Certificate-of-Analysis PDFs whose Search Codes resolve at the laboratory’s public verification surface under the Enhanced Chem client name. Reports typically support identity, HPLC purity, and net content for the named sample. Additional product-page Janoshik image scans document purity when readable but blank Task Number, Unique Key, and Client on the published asset, so they are not treated as independently re-checkable at the laboratory portal. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A Tampa-fulfilled public catalog with standing per-size prices and a public certificate library whose Janoshik Analytical and Kovera Labs reports resolve at the laboratories’ public verification surfaces.
EVO Labs Research exposes a stock-aware public catalog of research peptides and a public /coa library that publishes current Janoshik Analytical and Kovera Labs batch reports. PeptideBenchmark ranks the regular per-vial list price and treats temporary sale pricing as a separate observed lane.
Testing transparency: Public COA library with Janoshik and Kovera provider verification. The public library publishes vendor-hosted batch reports from Janoshik Analytical and Kovera Labs. PeptideBenchmark confirms printed report codes and task/key pairs against each laboratory’s public verification surface where they resolve. The current reviewed set contains HPLC, identity, endotoxin, sterility, heavy-metals, and net-content results; each panel is recorded certificate by certificate and is not inferred where absent. Most current single-vial peptide SKUs have a matched certificate; comparable ready sprays appear in Ready sprays and hCG appears in IU hormones, while multi-vial sets, stacks, topicals, and support items remain outside current format lanes. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A Tennessee WooCommerce catalog with public standing prices and a public Freedom Diagnostics certificate library whose RIVN* search codes resolve under the RIVN Peptides client name at the laboratory’s public verification surface.
Rivn Peptides (rivnresearch.com; Rivn Research LLC) exposes a stock-aware catalog of injectable research vials. PeptideBenchmark ranks regular per-vial list prices, maps coded GLP SKUs and named blends to canonical compounds, and keeps bacteriostatic water, acetic acid, L-Carnitine, and promotional gifts outside the peptide board.
Testing transparency: Public COA archive with Freedom Diagnostics provider verification. Public certificate images carry Freedom Diagnostics RIVN* search codes. PeptideBenchmark confirms those codes against Freedom’s public accession lookup under the RIVN Peptides client name where they resolve. A minority of published images are retained as vendor-hosted documents only when the code does not currently resolve. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A U.S.-oriented WooCommerce catalog with public standing prices and a public COA library of Freedom Diagnostics certificates that resolve under the Peptaris client name at the laboratory’s public verification surface.
Alpha Peps exposes a stock-aware catalog of injectable research vials alongside capsules and topicals. PeptideBenchmark maps blend and short-label SKUs to canonical compounds and routes comparable vials, capsules, the qualifying nasal product, and hCG to their format-specific Pricing lanes; topicals and bac water remain outside Pricing.
Testing transparency: Public COA library with Freedom Diagnostics provider verification. The public COA library publishes Freedom Diagnostics certificate images with Pept* search codes. PeptideBenchmark confirms those codes against Freedom’s public accession lookup under the Peptaris client name where they resolve. A minority of published library cards are not currently retrievable from Freedom’s public object store and are retained as vendor-hosted documents only. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A Colorado-positioned WooCommerce catalog with public standing prices and a WordPress media library of Freedom Diagnostics and Kovera Labs certificates that resolve at the laboratories’ public verification surfaces.
Rocky Mountain Compounds exposes a stock-aware public catalog and publishes downloadable batch certificates in its public media library. PeptideBenchmark ranks the regular per-vial list price, maps house-coded GLP and related SKUs to canonical compounds, and treats temporary sale pricing as a separate observed lane.
Testing transparency: Public media COA archive with Freedom and Kovera provider verification. Downloadable Freedom Diagnostics and Kovera Labs certificates are publicly reachable through the WordPress media library even while HTML product and COA-library pages require a research-access account. PeptideBenchmark confirms Freedom Rock* search codes and Kovera KVR report codes against each laboratory’s public verification surface under the Rocky Mountain Compounds client name where they resolve. Multi-vial kits, bac water, Lipo-C, and storage cases stay outside the peptide board. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A public storefront with a clean per-variant product catalog and a public certificate library whose reports link directly to Freedom Diagnostics and resolve under the Amino Science client name.
Amino Science exposes a stock-aware public catalog of single-vial research peptides and a public COA library that links each current certificate straight to its Freedom Diagnostics report. PeptideBenchmark uses the regular per-vial list price as the base and keeps the sitewide percentage sale and select buy-one-get-one offers as separate optional lanes.
Testing transparency: Public COA library with live Freedom Diagnostics provider verification. Each library certificate links to a report hosted at Freedom Diagnostics that resolves under the Amino Science client name at the laboratory’s public accession lookup, supporting identity, HPLC/LC-MS purity, and net content. Most products publish a certificate per listed strength; a strength-specific report is not treated as testing every other strength, and the storefront’s marketing purity language is not inherited onto sterility or endotoxin panels the reports do not run.

Open profile A public U.S.-positioned Shopify storefront with stock-aware standing prices, an auditable mixed-cart spend ladder, and a 36-record batch archive spanning exact Freedom Diagnostics and ILS evidence.
Rescue Research USA exposes its current catalog and a searchable public COA table without requiring an account. PeptideBenchmark preserves each certificate, batch, product relationship, fingerprint, laboratory attribution, and exact provider route where the report independently resolves.
Testing transparency: Public provider-linked batch reports from Freedom and ILS. The October 3 review found 36 distinct certificates: 31 canonical Freedom Diagnostics reports and 5 ILS Laboratories PDFs. Newer ILS reports expose exact public verification tokens; older ILS PDFs identify the laboratory but expose only a generic lab URL and therefore do not receive a provider-verification badge.
Profile: rescue-research-usa
Open profile A Denver, Colorado storefront that publishes its full priced catalog openly and attaches laboratory certificates directly to the products they describe, with most of those reports carrying an independently checkable credential.
Mile High Peptide lists 49 products and 59 comparable research-vial rows across 36 distinct peptides, all readable without an account. Certificates are published as page images inside each product gallery rather than in a separate library, so PeptideBenchmark reads every published image and keeps laboratory-confirmed values separate from what the certificate picture alone shows.
Testing transparency: Product-attached certificates with provider verification at ILS and Kovera. The October 2, 2026 review found 16 distinct certificates across 14 product pages. 13 resolve independently at the issuing laboratory — 9 ILS Laboratories reports whose portal tokens return the certificate under the Mile High Peptide client name, and 4 Kovera Labs reports whose printed codes resolve to lab-hosted documents. The remaining 3 are BTLabs certificates: the laboratory is named and the printed identity, purity, potency and appearance results are recorded, but BTLabs operates no public report lookup, so those reports are not given a verification badge. Panel coverage is purity throughout, identity on 15 and net content on 14 of 16 certificates, with endotoxin reported on 2 reports; sterility is not reported on any certificate in this set.
Profile: mile-high-peptide
Open profile A Nebraska-identified storefront with account prompts for product browsing and a substantial preserved history of publicly readable batch documents.
Peptira uses account prompts in its browsing flow. During the September 24 review, its certificate library and individual files were also readable directly without signing in. On September 27, 2026, PeptideBenchmark reviewed the current index and preserved all 334 certificate records, including nine first found on September 24, 2026. Current, historical and discontinued labels reflect Peptira’s index on that date; they do not establish an exact match to a current product listing.
Testing transparency: Exact Freedom Diagnostics provider verification across a deep public batch archive. The preserved set contains 334 certificate records. Exact Freedom Diagnostics matches cover 254 records under the Peptira client name, including all nine records first found on September 24. The other 80 remain vendor-linked records without an independently confirmed report match. All 325 records known before September 24 retain the same archived bytes. Certificates are not assigned an exact product match without evidence.

Open profile A public storefront identifying a Wyoming postal address and separately stating in-house fulfillment from Virginia, with exact stock-aware pricing, unusually deep same-product volume tiers, and a certificate library that retains failed and depleted batch history.
Giga Compounds exposes its current catalog, inventory, cart discount composition, fulfillment schedule, and a searchable public COA library without an account. The vendor says orders ship by FedEx 2-Day from its temperature-controlled Virginia facility, with weekday fulfillment until 2 PM EST. PeptideBenchmark preserves each source PDF, exact product relationship, batch status, panels, fingerprint, and independently checkable laboratory route where one resolves.
Testing transparency: Public multi-lab COA library with Janoshik and Kovera provider verification. As of October 3, 2026 the public library has 46 downloadable certificate PDFs spanning Janoshik Analytical, Kovera Labs, and Chromate (up from 34 on July 28). It still includes active, depleted, pending, and 8 rejected reports rather than silently hiding failed batches. Of those reports, 13 check out on the lab’s own verify page (Janoshik and Kovera). A library row still points only at Janoshik’s generic verify page, which cannot identify a specific report.
Profile: giga-compounds
Open profile Peptide Tech ended its public peptide storefront on August 26, 2026. PeptideBenchmark retains the last public catalog prices and the previously reviewed certificate library as dated historical evidence, not current retail offers.
On August 26, 2026, Peptide Tech announced it was ending its peptide storefront and shifting to lyophilization, filling, and later API synthesis, with a remaining white-label fulfillment program. PeptideBenchmark keeps the last public prices observed August 25 and the previously reviewed public COA library. Those prices are excluded from current Pricing and Stack Builder. The former shopper referral path no longer reaches a Peptide Tech retail checkout.
Testing transparency: Retained public multi-lab COA library with report-level provider verification. The last public COA library contained 162 distinct lot documents from Freedom Diagnostics, Vanguard Laboratory, Janoshik Analytical, Chromate, and SafeCert. PB validates the document bytes and exact product relationship for every retained record. In the August 11 review, 117 distinct Freedom and Chromate reports resolved at the issuing laboratory; the 8 older Janoshik documents no longer resolved at Janoshik’s current verifier and remain named-lab evidence without a provider badge. That library is no longer on the live site; the archive is retained as historical evidence.

Open profile A broad U.S.-positioned storefront with public standing prices, audited same-product quantity tiers, and product-level third-party certificates that resolve independently at Freedom Diagnostics.
Alpha Pro combines a broad public catalog with product-level certificates across much of its current vial line. Of 60 distinct current certificates, 49 resolve byte-for-byte at Freedom Diagnostics and 11 remain vendor-published documents without independent provider confirmation.
Testing transparency: Product-level COAs with report-specific Freedom provider verification. Alpha Pro publishes 60 distinct current certificates across 54 product listings. PeptideBenchmark independently confirms 49 at Freedom Diagnostics and retains 11 as vendor-published documents without a provider badge. The capsule reports document identity and net content but do not report a purity assay result; no purity is inferred from their chromatography method or standard footer. The current certificate set does not report sterility, endotoxin, or heavy-metals panels.
Profile: alpha-pro-peptides
Open profile A Tempe, Arizona storefront that leads with same-day shipping and an unusually data-rich public testing layer, worth tracking as a transparency-forward US vendor.
Publishes a structured, per-batch COA archive covering the whole catalog — quantitative purity, average net content (fill accuracy), vials tested, and an endotoxin / heavy-metals / sterility safety panel per batch, all openly inspectable. That is a stronger public-evidence pattern than generic "COA available" language, though the testing is vendor-published rather than run through an outside verification portal.
Testing transparency: Public COA archive with per-batch purity and safety panel. Instant Peptides exposes a public lab-tests archive with per-batch, per-concentration certificates: quantitative HPLC purity, average net content, vials-tested counts, and endotoxin / heavy-metals / sterility results. The documents are vendor-published — no named third-party lab or externally verifiable report code — so it sits in the public-docs lane rather than provider-verified.
Profile: instant-peptides
Open profile Included because it is the clearest catalog-wide public-verification case in the current site and now acts as the strongest public-testing anchor in the vendor graph.
Still the cleanest repeated public third-party verification trail we have: product pages route directly into Janoshik-hosted result pages and Janoshik verification pages across a large portion of the catalog.
Testing transparency: Public Janoshik report + verification trail. EZ repeatedly exposes public “View Latest Lab Test Result” behavior that routes readers into Janoshik-hosted report pages and Janoshik verification pages. That is stronger than a vendor-hosted PDF archive because the verification step lives on the outside provider domain rather than only on the vendor domain.
Profile: ez-peptides
Open profile Included as part of the core shortlist of names repeatedly mentioned in research-vendor circles.
Now one of the strongest public-testing-transparency cases in the curated set because its Independent Certifications page exposes a large vendor-hosted archive spanning multiple certification categories and multiple named outside labs.
Testing transparency: Multi-lab provider verification archive. Peptide Partners publishes an Independent Certifications archive spanning purity, endotoxin, heavy metals, and sterility, and the bulk of it resolves to its issuing labs — Kovera Labs (live-verifiable at koveralabs.com), Chromate, TrustPointe Analytics, and BioRegen. That makes most of the archive provider-verifiable third-party evidence, not just vendor-hosted files.

Open profile Included as a recognizable research-vendor name with enough community familiarity to merit focused tracking.
Crush Research publishes a public testing index with batch details and certificate files. The September 30 review found 194 listed results: 167 complete PDFs and 27 preview sets whose complete PDFs could not be retrieved from Crush. For 22 of those preview sets, ILS Laboratories hosts the complete certificate for the same lot.
Testing transparency: ILS, Freedom Diagnostics and Vanguard provider verification of vendor-hosted certificates. Crush Research’s public testing index names ILS Laboratories, Freedom Diagnostics, Vanguard Laboratory, and BTLabs. As of September 30, 144 of its 167 complete certificate PDFs check out at the issuing laboratory under Crush Research and the exact lot listed on the index (mostly ILS, plus Freedom Diagnostics and Vanguard), and 22 more complete ILS certificates are available from ILS for results whose PDF Crush does not serve. BTLabs has no public lookup; its 17 certificates name BTLabs, Crush and the listed lot on the document itself. Complete certificates cover 74 of 81 reviewed products.

Polaris now has a substantial public testing surface: product-linked certificates cover the published catalog, with current Chromate and TrustPointe reports independently checkable at the issuing providers.
Testing transparency: Chromate + TrustPointe provider verification. Polaris publishes product-linked certificate media from Janoshik Analytical, TrustPointe Analytics, Chromate, Accumark Labs, and BTLabs. PeptideBenchmark confirms current Chromate and TrustPointe identities at their provider-controlled verification surfaces; older Janoshik reports remain named-lab, source-linked documents when the present Janoshik lookup no longer resolves.

Open profile Included in the shortlist as a recognizable research-vendor name with public COA evidence and a now-live tracked profile.
Interesting less for public location clarity and more for the layered transparency pattern: repeated public COA links and COA-style image assets on product pages, plus vendor-hosted documents that identify outside testing work.
Testing transparency: TrustPointe, Vanguard & MZ Biolabs provider verification. Kimera’s COAs name and resolve to multiple outside labs — TrustPointe Analytics, Vanguard Laboratory (verifiable in the verifiedbyvanguard database), MZ Biolabs, and NuMega Resonance Labs — alongside a public `COA` link on product pages. That is provider-verifiable third-party evidence, not just vendor-hosted images.

The public COA library publishes per-lot certificate pages with AV Analytics, Freedom Diagnostics, and Bioviridian PDFs plus Chromate images; PeptideBenchmark confirms resolving Chromate Job/Access pairs at chromate.org and Bioviridian COA###### codes at bioviridians.com. AV Analytics PDFs remain vendor-hosted source documents without independent provider verification; Freedom Diagnostics PDFs that print client Wholesale do as well. Bacteriostatic water stays outside the retail single-vial board.
Testing transparency: Public COA library with Chromate and Bioviridian provider verification. The public /coa/library hosts per-lot certificate pages with AV Analytics, Freedom Diagnostics, and Bioviridian PDFs plus Chromate images. Chromate Job/Access pairs and Bioviridian COA###### codes are confirmed at each laboratory’s public verification surface when they resolve; 1 Chromate image without a resolving provider route remains vendor-hosted only. AV Analytics documents remain vendor-hosted source evidence without independent provider verification. Freedom reports that name client Wholesale also remain vendor-hosted rather than Bench Grade–named provider records. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.
Profile: bench-grade-peptides
Open profile Included because it is part of the manually selected research-vendor watchlist, even though the current dataset name is shorter.
Blank’s public product-page grid currently exposes 217 certificate and lookup relationships across 33 of 49 reviewed products: 129 vendor-hosted PDFs, 86 Horizon or Freedom laboratory-lookup links, and 2 bare destination labels that are not counted as documents or laboratory lookup results. The reviewed records average about 99.5% reported purity, with endotoxin results in 67 relationships.
Testing transparency: Public Horizon Analytical & Freedom Diagnostics COAs with laboratory-lookup routes. The current review records 217 evidence relationships: 129 vendor-hosted PDFs, 86 links to Horizon Analytical’s or Freedom Diagnostics’ lookup, and 2 bare labels not counted as documents or laboratory lookup results. Horizon Analytical is named on 137 relationships and Freedom Diagnostics on 78. The documents report identity on 129 relationships, HPLC on 85, endotoxin on 67, and net content on 17; no heavy-metals or sterility result is inferred. This pass records laboratory-lookup routes but no checked-lot total, so the earlier 108-lot verification claim is no longer used. The public manufacturing trail is still thinner than the document trail: the specific Missouri cGMP manufacturing partner is not clearly identified in the public materials reviewed.
Tracked under the shorter dataset name "Blank."
Profile: blank
Open profile Included as a community-known research vendor whose per-product COAs are third-party Freedom Diagnostics reports with public accession verification.
A member-gated storefront whose /lab-results pages sit behind a sign-in, while the underlying public document bucket currently retains 71 product-linked certificate origins. 65 resolve through Freedom Diagnostics; the rest, including 2 Vanguard Laboratory documents, stay named-lab or vendor-hosted evidence.
Testing transparency: Per-product COAs with Freedom Diagnostics provider verification. Peptide Supply Co gates its Squarespace /lab-results pages behind a member sign-in, but each page embeds a certificate from a public storage bucket. 65 certificate origins carry Freedom Diagnostics accession/search codes that resolve at the provider; the rest, including 2 Vanguard Laboratory reports, remain named-lab or vendor-hosted evidence. Identity and HPLC appear throughout the retained set, net content and endotoxin on most reports, heavy metals on a minority, and sterility on a few. PB shows those panel results certificate by certificate rather than describing the archive as a uniform full-safety panel.
Profile: peptide-supply-co
Open profile Included as a recognizable U.S.-based research-vendor name in the current focus set.
A login-first storefront whose certificates turn out to be public: every COA image sits on the vendor’s public S3 bucket, and 59 are Freedom Diagnostics or BioRegen reports (high reported purity) independently verifiable at the lab, alongside named Vanguard Laboratory certificates.
Testing transparency: Per-product Freedom Diagnostics COAs with public provider verification. Elite Research USA gates its storefront behind a member sign-in, but every certificate image is served from a PUBLIC S3 bucket (eliteresearch-public.s3…/certificates/), anonymously reachable. The certificates are third-party: 59 are provider-verifiable, mostly Freedom Diagnostics COAs carrying a public accession/search code (e.g. Elit2602020426) independently verifiable at freedomdiagnosticstesting.com and a few BioRegen reports; the rest include other BioRegen documents and Vanguard Laboratory reports (named accredited lab; Elite’s Vanguard COAs are not in Vanguard’s public per-COA database). Verified reports show high purity. So the underlying evidence is public provider-verifiable, even though the browsing experience is login-first.
Profile: elite-research-usa
Open profile Included because it is one of the more repeatedly cited U.S. research-vendor names in current transparency-focused community lists and clearly belongs in the same comparison set as Peptide Partners, Kimera Chems, and Elite Research USA.
Nearly every product carries a public MZ Biolabs certificate set — HPLC-UV purity (averaging ~99.7%), mass-spec identity, and an endotoxin report — a genuinely deep named-lab document layer, though MZ offers no public per-COA lookup, so the certificates are inspectable rather than independently verifiable at the lab.
Testing transparency: Public sitemap-derived COA / MS / endotoxin image layer. Pure Peptides names MZ Biolabs as its third-party testing lab and publishes a per-product certificate set — HPLC-UV purity (~99.7% average), mass-spec identity, and endotoxin — as public image assets across most of the catalog. That is a strong named-lab document layer, but MZ Biolabs exposes no public per-COA verification lookup, so these read as inspectable vendor-hosted certificates from a named lab rather than provider-run verification that a reader can confirm at the lab’s own site.
Tracked under the current benchmark dataset name "Pure Peptides Bio."
Profile: pure-peptides-bio
Open profile Included as part of the community-known shortlist, with a normalized dataset match already in place.
Now one of the stronger curated testing-transparency candidates because its public COAs page exposes a structured COA map rather than just generic lab-testing language.
Testing transparency: Public COA map with provider verification. Peptide Plugs publicly exposes vendor-hosted COA files and Freedom Diagnostics accession-based verification links from its public COAs page, which is a meaningfully stronger pattern than vague homepage purity claims.
Tracked under the current dataset name "PeptidePlugs."
Profile: peptideplugs
Open profile Included because its broad catalog exposes repeatable public COA archive paths across many products.
A large, provider-verified COA archive: a public per-batch API surfaces a Freedom Diagnostics search code for nearly every product, and those codes resolve live in Freedom’s public index.
Testing transparency: Freedom Diagnostics provider verification across the archive. Simple Peptide publishes a public COA archive (a WordPress `coa-archive` REST API) that exposes a Freedom Diagnostics search code, purity, net content, and panels for each batch. In the latest audit, 185 of 190 certificate origins across 52 products independently resolved to a real Freedom Diagnostics report in the lab’s public index (a fake code correctly returns not-found), at ~99.5% average purity. The remaining 5 are attributable vendor documents kept without a provider badge.
Profile: simple-peptide
Open profile Included as a community-known research vendor we want to keep surfaced even before deeper editorial coverage lands.
No longer just a hold-and-watch name. The live site exposes a real public COA archive with outside-provider links, plus a public shop/catalog surface that makes Orbitrex a meaningful trust-review candidate rather than a placeholder.
Testing transparency: Public COA archive with provider-linked batch reports. Orbitrex publicly exposes a `/coas/` archive with batch-level certificate links. PeptideBenchmark validates the underlying Dropbox documents and live provider reports rather than treating every listed link as evidence; the current archive includes validated Kovera, Chromate, TrustPointe, ILS Laboratories, Freedom Diagnostics, and Dropbox-hosted records.
Profile: orbitrex-peptides
Open profile Included as an active name in the curated watchlist and already connected to a live vendor profile.
A genuine multi-lab case: its public test-results page publishes certificates from independent labs — Janoshik, BioRegen, Chromate, and MZBiolabs — and the first three each expose a public verifier, so 17 of Evolve’s reports can be checked directly at the lab rather than taken on the vendor’s word.
Testing transparency: Provider verification across independent labs (Janoshik, BioRegen, Chromate; MZBiolabs named-lab only). Evolve publicly exposes a `/test-results/` page and an open shop surface rather than a login-first catalog. Across its public COA set, 17 reports are independently provider-verifiable: Janoshik test reports resolve at verify.janoshik.com by task number and printed key, BioRegen certificates carry a public COA/security-key pair, and Chromate reports validate against chromate.org by job number and access code. Most of the remaining certificates are from MZBiolabs — a named third-party lab that publishes HPLC purity and dedicated endotoxin reports but has no public per-certificate lookup, so those count as named-lab evidence rather than provider-verified. Reported HPLC purity averages ~99.0%, with endotoxin panels on 42 certificates.
Profile: evolve-peptides
Open profile Included in the current focus set as a now-mapped research vendor with a public rebrand and address trail.
A standout verified case: a deep public per-batch archive links 287 Freedom Diagnostics certificates — a named outside lab — 286 of them carrying an accession / Search Code that resolves in Freedom’s public lookup, with exact HPLC purity averaging ~99.6% and endotoxin results on many batches.
Testing transparency: Third-party Freedom Diagnostics COAs with public provider verification. Oath publishes a public per-batch COA archive (a WordPress lab-results library) where every certificate is from Freedom Diagnostics, an outside lab, and 286 of 287 carry an accession / Search Code that is independently checkable at the provider’s public lookup. The reports carry HPLC-UV purity (~99.6% average), LC-MS identity, and endotoxin results on many batches — broad, provider-verifiable evidence across the catalog, not just vendor-hosted documents.
Profile: oath-research
Open profile Included because it is now one of the stronger high-ranked consensus vendors we want visible in the curated layer, and it exposes a real public lab-reports surface rather than only generic testing language.
One of the deeper public certificate trails in the catalog: nearly every product carries third-party Janoshik Analytical reports — split by test type (purity, endotoxin, TFA/net content, and in some cases sterility) — with reported purity averaging around 98.2% and 49 of 169 certificate records independently confirmable at the lab.
Testing transparency: Third-party Janoshik Analytical COAs with public provider verification. Verified Peptides publishes per-product Janoshik Analytical “TEST REPORT” certificates, and those that carry a task number plus a unique key resolve the report two-factor at verify.janoshik.com (49 of 169 certificate records) — so the certificate can be confirmed at the lab rather than taken on the vendor’s word. Because it posts separate reports per test type, many peptides carry not just a purity number but endotoxin and sometimes sterility panels, which is broader safety coverage than most vendors publish.
Profile: verified-peptides
Open profile Included because it is a high-ranked consensus vendor with explicit lot-linked COA positioning and a visible public COA lookup path.
Paramount exposes a public product-and-variation COA lookup, but the current evidence is narrower than the prior Janoshik description implied. Across 158 reviewed product pages, 272 product or variation records were checked: 86 returned certificate pages and the rest returned no record. The reviewed set contains 537 relationships to 537 distinct vendor-hosted COA images.
Testing transparency: Public product-and-variation lookup with vendor-hosted COA images. The public lookup needs no account and can be checked by product or variation. Its results are images served from Paramount’s own site: all 537 reviewed relationships are vendor-hosted COA images. Its 86 current-batch certificate hits name Janoshik and Accumark Labs documents. The Accumark sample codes resolve at Accumark Labs under the Paramount client. The Janoshik names on those images still have no recovered laboratory credential. Lot numbers and analysis dates remain useful document fields, but a searchable vendor result does not by itself establish an issuing laboratory.
Profile: paramount-peptides
Open profile Included because it ranks highly on the board and now has a real trust-review surface rather than just a score-driven placeholder.
Stronger than the first gated impression: Mile High publishes a public lot-COA archive that covers 67 of 70 reviewed products. The current review separates 230 public evidence relationships into 35 vendor-hosted certificate images, 79 laboratory-lookup links, and 116 vendor-linked public documents.
Testing transparency: Public COA archive with 79 laboratory-lookup links. Mile High’s current public review contains 35 vendor-hosted certificate images, 79 laboratory-lookup links, and 116 vendor-linked public documents. The lookup tier comprises Kovera, Chromate, Vanguard, and ILS links; PB keeps the vendor-linked document and vendor-hosted image tiers distinct rather than treating every retained item as a provider result, and it excludes the storefront’s product photos, navigation links, and credential-less laboratory entry points from the count. The current review does not separately itemize sterility or endotoxin documents. The storefront routes anonymous visitors into a research-access gate, but the certificate archive remains inspectable.
Profile: mile-high-compounds
Open profile Included because it has a more intentional public operator and Texas-based positioning than many thin storefronts, and we want that pattern represented in the curated set.
Forge looks more operator-forward than many smaller vendors: Texas-based language, batch-tested messaging, and a public /coas/ archive that pairs current cards with historical PDFs. The current review retains 62 distinct certificate documents across 25 covered products; 60 current or historical reports resolve at Freedom Diagnostics, ILS Laboratories, or BioRegen.
Testing transparency: Multi-lab provider verification across current and historical batches. PeptideBenchmark reads every current and historical PDF exposed on /coas/, not only the structured current-card credentials. 60 retained reports currently resolve at Freedom Diagnostics, ILS Laboratories, or BioRegen. The remaining vendor-hosted documents stay named-lab or source-linked evidence without an unearned provider badge, including Kovera Labs reports, a Vanguard Laboratory report and an HPLC report without a public laboratory lookup. Panel coverage is report-specific: the current product set broadly reports identity, with HPLC, net content, endotoxin, and sterility on narrower subsets; no heavy-metals result is inferred from documents that do not report it.
Profile: forge-performance-co
Open profile Included because it is now a known U.S.-footprint vendor with explicit COA-on-site language and a current live storefront worth comparing against stronger transparency leaders.
Puratek now reads as a real public certifications-archive case with a thinner but meaningful public batch-report surface tied to named outside-lab language.
Testing transparency: Freedom Diagnostics provider verification archive. Puratek’s public `/coa/` and `/certifications/` archive resolves its batch reports to Freedom Diagnostics (accession-searchable at FreedomDiagnosticsTesting.com), with at least one ILS Laboratories report in the set. That is provider-verifiable public evidence, not just vendor-hosted images.
Profile: puratek-peptides
Open profile Included because it is one of the stronger public-facing trust candidates in this expansion batch, with named outside labs and a visible public COA path.
One of the strongest public certificate trails in the catalog: a public /coa-lookup/ gallery pairs each product with batch-level third-party lab reports — Freedom Diagnostics, Chromate, and Kovera Labs — with reported purity averaging around 99.6%, and 95 of 211 certificate records can be confirmed at the issuing lab.
Testing transparency: Freedom Diagnostics + Chromate COAs with public provider verification. GenPeptide’s public /coa-lookup/ gallery lists batch-level reports across the catalog, and many can be checked at the lab rather than taken on the vendor’s word: Freedom Diagnostics reports resolve by accession on the lab’s public search, Chromate reports by their two-factor job + access code confirmed live at chromate.org, and a set of Kovera Labs reports by their KVR code. 95 of 211 certificate records carry a live provider-verification link — provider-verifiable public evidence rather than generic third-party language.
Tracked under the current benchmark dataset name "Genpeptide."
Profile: genpeptide
Open profile Included because it now has a clearer U.S. footprint, visible COA navigation, and a public quality-assurance layer that is stronger than a bare storefront.
The lab-results layer turns out to be substantial: a public /lab-results/ library maps most of the catalog to per-batch third-party reports — Freedom Diagnostics and Kovera Labs — and nearly every one can be confirmed at the issuing lab, with a set of products also carrying separate endotoxin reports.
Testing transparency: Third-party Freedom Diagnostics + Kovera Labs COAs with public provider verification. Ion’s public /lab-results/ library lists per-batch reports across 92 products, and the large majority can be checked at the lab rather than taken on the vendor’s word: Kovera Labs reports resolve by their KVR code on Kovera’s public lookup, and Freedom Diagnostics reports by their accession on Freedom’s public COA search. A subset of products publish separate Freedom endotoxin reports on top of purity. That is broad, provider-verifiable public evidence rather than the performative lab page it first appeared to be.
Profile: ion-peptides
Open profile Included because it is a U.S.-listed research vendor already on the board and now part of the active affiliate/curated comparison set.
A public COA library with reports from BioRegen, Bioviridian, and Janoshik Analytical. Certificates with a confirmed matching laboratory record receive provider verification; other documents remain vendor-hosted evidence.
Testing transparency: Provider verification at BioRegen, Bioviridian, and Janoshik. The public library includes reports issued by BioRegen, Bioviridian, and Janoshik Analytical. Provider verification requires an exact matching laboratory record, including the document identity and client. Documents without that confirmation remain vendor-hosted evidence. Current product coverage, verification counts, and reported purity appear in the live evidence summary.
Profile: nextgenpeps
Open profile Included because its catalog is openly browsable and selected product pages link to exact Freedom Diagnostics reports that can be checked on the provider-controlled report host.
Peptime pairs an openly browsable catalog with 5 exact product-linked Freedom Diagnostics reports. Of these, 5 currently resolve on the provider-controlled report host, with reported HPLC purity, identity, and net-content results.
Testing transparency: Selected Freedom Diagnostics reports with provider verification. 5 of 15 reviewed Peptime products link to exact Freedom Diagnostics reports, and 5 reports currently resolve on the laboratory-controlled report host. The reports average about 99.7% stated purity and include HPLC, identity, and net-content results. This is genuine provider-linked evidence, but this partial catalog coverage remains materially narrower than a broad whole-catalog archive.
Profile: peptime
Open profile Included because Ameano pairs an openly priced catalog with a public, batch-organized certificate archive and independently checkable Janoshik reports.
Ameano’s public batch archive exposes distinct current certificates: independently confirmed Janoshik reports and 2 Freedom Diagnostics documents retained without independent provider confirmation.
Testing transparency: Public batch archive with Janoshik verification and 2 unconfirmed Freedom documents. The current archive contains distinct Janoshik certificates with exact task-and-key verification links, plus 2 Freedom Diagnostics documents without a confirmed independent provider binding. Certificate relationships cover 30 of 63 in-scope catalog products. Panel evidence remains report-specific: a report requesting identity and amount while excluding peptide purity does not count as a purity test.
Profile: ameano-peptides
Open profile Included because APR pairs a clean public WooCommerce catalog with a per-product COA image from a named third-party lab (Janoshik Analytical), which is materially more than generic purity language even though the reports stop short of one-click verification.
An openly browsable simple-product catalog where the product-gallery COA images are Janoshik Analytical TEST REPORTs — reading them shows ~99.5% average HPLC purity with identity and net-content quantitation, each stamped with a Janoshik task number.
Testing transparency: Product-gallery COA images from a named third-party lab. Every product-gallery COA is a Janoshik Analytical TEST REPORT (~99.5% average purity across 26 products, with a Janoshik task number). Janoshik is a reputable third-party lab, but these reports print only the task number, not the on-report unique key, so they can’t be deep-verified two-factor at verify.janoshik.com — this is strong named-lab documentation, not one-click provider verification.
Profile: american-peptide-research
Open profile Included because it pairs live public pricing with product-specific certificate records. ILS Laboratories and Freedom Diagnostics records retain provider-checkable routes, while Ethos Analytics certificates remain explicitly labeled vendor-document evidence.
Amino Club has a substantive batch-level testing record spanning ILS Laboratories, Freedom Diagnostics, and Ethos Analytics, with provider-checkable reports kept distinct from vendor-published certificates that lack an independent public verification portal.
Testing transparency: Provider verification for ILS and Freedom reports plus labeled Ethos vendor documents. Certificates are linked to exact products, and current product coverage appears in the live evidence summary. ILS Laboratories and Freedom Diagnostics reports expose provider-checkable routes. Ethos Analytics certificates come from Amino Club’s public registry and downloadable document links; because Ethos exposes no independent public verifier, those records remain vendor-stated rather than provider-verified. Individual records show only the identity, purity, net-content, endotoxin, sterility, and heavy-metals evidence actually reported.
Profile: amino-club
Open profile Included because Apex is on the current curated-expansion list and already exists in the broader benchmark dataset under a clean matched vendor slug.
Now a meaningful public-transparency case rather than just a queued vendor. Apex exposes a public /products catalog with live dosage-level pricing on product pages, plus a separate public /verify COA browser and product-page Certificate of Analysis callouts.
Testing transparency: Public product-page COA plus public verify browser. Apex publicly exposes two useful trust surfaces: product pages carry a visible Lab Verified / Certificate of Analysis callout, and the separate /verify browser exposes per-product COA routes on the vendor domain. That is materially stronger than generic testing language alone, while still remaining a vendor-hosted documentation pattern rather than a provider-controlled live verification system.
Profile: apex-peptides
Open profile Included because Nationwide is a disclosed affiliate relationship and exposes a public WooCommerce storefront plus 94 attributable Freedom Diagnostics certificates across 49 current products. 87 resolve to exact laboratory-owned report objects; 7 remain preserved vendor copies whose corresponding provider URLs currently return 404.
A public catalog with clearly listed products, live variable-product pricing, and 94 downloadable Freedom Diagnostics certificates across 49 products. The reviewed documents average about 99.6% HPLC-UV purity and report identity and net content; 87 have exact laboratory-controlled verification routes.
Testing transparency: Freedom Diagnostics provider verification. Nationwide currently exposes 94 attributable Freedom Diagnostics certificates across 49 of 72 catalog products. PeptideBenchmark matched 87 to exact Freedom-owned PDFs by client, search code, accession, and lot. The remaining 7 are retained as source-linked vendor documents because their expected laboratory objects currently return 404; they are not labeled independently verified.
Profile: nationwide-peptides
Open profile Included because it is a disclosed affiliate relationship and a distinct storefront from apexpepts.com, so we should track it separately rather than collapsing the two Apex domains into one vendor identity.
A separate Apex storefront with an account-gated shop and stable product routes. Signed-in review confirms usable pricing and product-page COA sections, which makes it a real gated comparison case rather than just a placeholder identity.
Testing transparency: Product-page certificates with Freedom Diagnostics provider verification. Apex-Peptides.com publishes certificate images on product pages. Freedom Diagnostics reports with exact verified laboratory links are publicly checkable at the provider. Vendor-hosted documents without a confirmed provider route remain unconfirmed; this includes Janoshik Analytical images without a verified laboratory link. Current product coverage and verification counts appear in the live evidence summary. Previously observed certificates remain in the archive when they leave current product pages. Shopping and pricing require an account.
Profile: apex-peptides-com
Open profile Included because it now has real structured coverage: a public product sitemap, live product-page pricing, and a small but genuine public lab-results surface.
A mixed but still legitimate public case. Next Chems exposes a browsable public storefront with product-level pricing and inline dosage variants, while the trust side currently rests on a narrow public COA page plus repeated product-page “COA available” language rather than a broad certificate archive.
Testing transparency: Partial public lab-results archive. Next Chems currently exposes a small public lab-results / COAs page with vendor-hosted PDFs, and many product pages also make an explicit public COA-available claim. That is enough to create a real trust profile, but it is still much narrower than the broad archive or provider-run verification patterns we treat as stronger proof tiers.
Profile: next-chems
Open profile Included because it pairs a complete public structured pass (product sitemap, live product-page pricing, a dedicated public lab-test archive) with third-party COAs from Bioviridian Inc. that are independently verifiable at the lab’s own domain.
A broad public storefront with product-page variation pricing and a per-product lab-test archive. The reviewed archive includes Bioviridian Inc. certificates — ~99.8% average purity with unusually deep panels (HPLC, identity, endotoxin, and heavy-metals) — whose Web Verification Codes resolve at bioviridians.com.
Testing transparency: Bioviridian provider verification. LA Peptides’ lab-test pages embed Bioviridian Inc. COAs whose Web Verification Codes (COA######) resolve to lab-hosted records. The current review found 93 provider-verifiable certificate-to-product relationships among 112 reviewed relationships; those map to slightly fewer distinct Bioviridian documents because a certificate can support more than one related product page. This is independent-provider public evidence, not just vendor-hosted images.
Profile: la-peptides-net
Open profile Included because every product-attached certificate is a third-party Bioviridian Inc. COA that resolves at the lab’s own domain, while the public catalog exposes standing prices — a fully checkable pricing and testing pass without relying on a vendor-stated testing claim.
A WooCommerce storefront whose testing evidence is far deeper than it first appears. No product description mentions testing at all, and the vendor’s own certificate index sits behind an account, yet nearly every vial product carries a Bioviridian Inc. certificate as an attached document — third-party HPLC-MS with identity, purity, endotoxin, and heavy-metals panels, each printing a Web Verification Code the lab hosts and resolves. Every certificate read names PepLogix on its face, so attribution comes from the issuing lab rather than from us.
Testing transparency: Bioviridian provider verification. Nearly every PepLogix vial product attaches a Bioviridian Inc. COA. Every certificate prints a Web Verification Code (COA######) that the lab hosts at bioviridians.com/coas/<code>.pdf and resolves through its public coa-search.html lookup, and each one PeptideBenchmark read was confirmed against that host — a fabricated code 404s there, so the check distinguishes a real certificate from a published image. The certificates also name PepLogix as the vendor, so attribution is stated by the lab.
Profile: peplogix
Open profile Included for its retained pricing record. PeptideBenchmark previously captured 29 directly comparable rows from Strand Bio’s public price list; those accepted rows remain as a dated comparison because PeptideBenchmark has not restamped them as a new anonymous quote. The September 29 public-markup audit detected no Strand Bio testing evidence on 82 reachable research, compliance, and catalog pages after the researcher-login route migrated to the public catalog, while otherwise unlabelled raster image pixels remain outside that claim.
PeptideBenchmark retains 29 formerly public catalog records, each with one vial size and one accepted price, so the dated range still normalizes to $/mg without a deferral. Catalog HTML is now publicly reachable after the researcher-login route migrated to the public catalog; PeptideBenchmark has not restamped those August 15 rows as a new anonymous quote. On September 29, PeptideBenchmark checked 82 publicly reachable research, compliance, and catalog pages, 14 exact certificate-route 404s, and 1 exact authentication gate reached from public links: the partner feed returned its reviewed 401 approved-researcher response after the researcher-login route migrated to the public catalog. It found no certificate, purity figure, batch identifier, laboratory name, or verification code in the audited public markup. Otherwise unlabelled image pixels were not inspected.
Testing transparency: Pricing-first curated coverage. The bounded September 29 audit found no certificates of analysis, purity results, batch identifiers, laboratory names, or verification codes in Strand Bio’s public research, compliance, and catalog markup. PeptideBenchmark checked 82 reachable pages and 14 conventional certificate routes; none served a public PDF document. Of 1 exact authentication gate reached from public links, the partner feed returned its reviewed 401 approved-researcher response after the researcher-login route migrated to the public catalog. Otherwise unlabelled image pixels are outside this finding. Detectable testing language on public pages appeared only in reviewed comparison or policy context.
Profile: strand-bio
Open profile A Miami-identified Shopify storefront whose GLP-1 line carries Freedom Diagnostics certificates that resolve independently at the issuing laboratory, attached to a broad openly priced catalog.
Prime Lab Peptides publishes certificates as product-gallery images rather than in a certificate library, and the strongest of them verify at Freedom Diagnostics under the Prime Lab client name. That verified evidence is concentrated on the GLP-1 range; most of the catalog carries vial photography only. PeptideBenchmark normalizes the full peptide range to $/mg, withholds listings the vendor marks unavailable, and separates independently confirmed certificates from named-lab reports that cannot currently be checked.
Testing transparency: Product-gallery COAs with Freedom Diagnostics provider verification. Certificates are attached to product pages as gallery images with no distinguishing filename, so PeptideBenchmark identifies them by reading each image rather than by its name. Freedom Diagnostics certificates are confirmed against the laboratory’s own host under the Prime Lab client name and carry accession, lot, net peptide content and HPLC-UV purity. Janoshik test reports on the same surface state a task number, and 2 also print their unique key, but Janoshik answers automated checks with a managed challenge, so those remain named-lab evidence without a provider badge.

Open profile A Wyoming-registered WooCommerce storefront with a fully open catalog API and a batch-level certificate library covering 18 of its 23 reviewed products.
BIOLENO publicly lists price, stock, and dosage information, and pairs 18 of its 23 reviewed products with a BTLabs batch certificate on its public COA page. PeptideBenchmark normalizes the entire peptide range to $/mg without a deferral and preserves each certificate with its batch identifier, purity, and measured potency. The certificates are named-lab documents rather than independently verifiable reports, and several report a measured quantity outside the specification printed on the certificate itself.
Testing transparency: Public batch COA archive with named-lab BTLabs reports. The public COA page links a batch certificate for 18 of 23 reviewed products as a signed storage object that requires no account. Every certificate is issued by BTLabs and names BIOLENO as the customer, reporting HPLC purity, HPLC potency, FTIR identity, and appearance. BTLabs publishes no public verification portal, so PeptideBenchmark records these as named-lab vendor-hosted documents rather than provider-verified reports.

Open profile A Wyoming-registered storefront with a public COA archive containing current and historical certificates, including reports that can be checked at Freedom Diagnostics, Horizon Analytical, or BioRegen.
Bluum Peptides presents an age gate and a public COA lookup. PeptideBenchmark keeps current-batch and historical certificates, distinguishing reports confirmed at Freedom Diagnostics, Horizon Analytical, or BioRegen from documents that remain vendor-hosted. The linked review and certificate database show the current evidence counts.
Testing transparency: Public COA archive with provider verification and vendor-hosted documents. The documents name Freedom Diagnostics, BioRegen, Horizon Analytical, Janoshik Analytical, MZBiolabs, and Vanguard Laboratory. Reviewed documents include HPLC, identity, net content, endotoxin, and heavy-metals results; none reports sterility. Current product matches are kept distinct from historical or unmatched certificates. A laboratory name printed on a document does not establish provider verification.

Open profile Included because Swiss Chems now has a real structured curated pass: a public peptide storefront with enough visible pricing to normalize a meaningful simple-product slice, plus 92 public certificates, 38 of which carry exact Janoshik task-and-key credentials.
A meaningful but mixed public-transparency case. Swiss Chems exposes 92 current certificates across its public testing archive; 38 carry exact Janoshik task-and-key credentials. The other 54 remain vendor-hosted evidence, including 36 Freedom Diagnostics-named reports. Much of the pricing surface still shows price ranges on variable products rather than exact per-option prices.
Testing transparency: 92 public certificates; 38 Janoshik-verifiable certificates. The current review covers 92 distinct vendor-hosted certificates. 38 carry exact Janoshik task-and-key credentials. The remaining 54 stay vendor-hosted-only: 36 name Freedom Diagnostics without a completed laboratory lookup, 2 name Vanguard Laboratory without a completed laboratory lookup, 1 is a Swiss Chems-issued NMR certificate, and the rest do not identify a laboratory.
Profile: swiss-chems
Open profile Included because TCore now has a real public curated pass: a browsable WooCommerce shop with live product-page variation pricing, plus repeated public Certificate of Analysis signals directly on product pages.
A solid vendor-hosted transparency case. TCore exposes a public storefront with inline variation pricing on variable products, and many product pages directly embed COA images inside the main product gallery instead of limiting trust language to generic claims.
Testing transparency: Public product-page COA gallery pattern. TCore embeds COA images directly in the WooCommerce product gallery; the current review retains 39 Vanguard Laboratory certificate images across 31 products. 37 report HPLC results, 37 report measured content, and 2 report identity; these sets overlap, and no reviewed certificate reports endotoxin, heavy metals, or sterility. Reported purity averages ~98.7% among certificates with a purity value. Vanguard is an ISO 17025:2017 / A2LA-accredited US lab (Certificate #6377.01), but its published accredited scope does not cover peptide analysis. The images remain vendor-hosted, and TCore’s reviewed report codes are absent from Vanguard’s opt-in public database at verifiedbyvanguard.com.

Testing transparency: Public product-gallery COA image pattern. Vital Core embeds 66 COA image assets across 44 of 58 reviewed products. The 44 certificate records come from named third-party labs: 9 MZBiolabs reports (HPLC-UV-MS purity plus mass-spectrometry identity, often a two-page certificate) for SARMs, and 35 Vanguard Laboratory reports for peptides. The reviewed set averages ~99.3% reported purity. Vanguard is A2LA / ISO 17025 accredited, although its listed accredited scope does not cover peptide analysis. Vanguard also runs a public COA-verification database (verifiedbyvanguard.com), but Vital Core’s reports are not in it — the brand has not opted into Vanguard’s public data-sharing, so its Vanguard COAs cannot yet be pulled independently from the lab. Named third-party labs, not bare claims, though the certificates are currently vendor-hosted images.

Open profile Included because Vortex Research has a public WooCommerce storefront with simple-product pricing and prominent Certificate of Analysis language emphasizing independent ISO-accredited lab testing on every batch.
A focused 30-product catalog with a "COA Verified" badge on every product, though only a small subset currently has downloadable Freedom Diagnostics certificates — the rest show "COA Coming Soon".
Testing transparency: Freedom Diagnostics COAs (rollout stalled). Vortex Research uses Freedom Diagnostics for independent testing, with COAs accessible via a modal on the product pages that have one. As of September 21, 2026, published COAs cover 1 of 30 products, and the vendor labels the rest "COA Coming Soon — ETA: 2 weeks". Accession codes on published certificates are verifiable at freedomdiagnosticstesting.com.

Open profile Included because Ascension Peptides has a public storefront with openly visible pricing, branded GLP labels, and COA language on the public site.
A mid-sized catalog with branded labels (R-30, T-30, C-10, S-5) and standard peptide offerings. Public storefront with openly visible pricing.
Testing transparency: Kovera Labs provider verification. Ascension publishes a public COA archive of 84 certificates at ~99.5% average purity: 39 are Kovera Labs reports with deep panels (HPLC, identity, endotoxin, sterility, heavy-metals, net-content), 38 of them live-verifiable at koveralabs.com, and 45 are MZ Biolabs reports. This includes provider-verifiable third-party evidence, not the text-only callouts we first recorded.

Open profile Included because Atomik Labz combines a large public catalog with broad product-level testing-document coverage and independently checkable Janoshik reports.
A large-catalog vendor with strong benchmark coverage and competitive pricing on core peptides and GLP-style listings. Its customer-visible product galleries (the storefront requires a login) expose 409 distinct current vendor-published document images across 106 of 118 reviewed product listings. Among them, 103 images are labeled Janoshik Test-Report; 84 have an exact task-and-key lookup tied to the current gallery image, while the rest remain without a confirmed provider binding.
Testing transparency: Per-product testing galleries with 84 provider-verifiable records from distinct Janoshik tasks. Atomik publishes current image-to-product relationships representing 409 distinct vendor-hosted images. Of the 103 images labeled Janoshik Test-Report, 84 have exact task-and-key lookups and the rest remain without a confirmed provider binding. Outside those exact bindings, PB does not assign a laboratory, purity result, tested panel, or provider status from filenames, layout, or logos; this review does not publish aggregate panel coverage.
Profile: atomik-labz
Open profile Included because Bio Edge has a large peptide catalog with a Certificate of Analysis published on every product page, many of them third-party lab reports that can be independently verified.
A wide catalog that pairs each product with a public Certificate of Analysis — third-party reports from Kovera Labs and MDx BioAnalytical Laboratory, plus Freedom Diagnostics and Janoshik Analytical, with many products showing several lots. Reported purity averages around 99.7% and most reports carry endotoxin, heavy-metals, or sterility panels alongside HPLC and identity.
Testing transparency: Third-party Kovera Labs and MDx COAs with public provider verification. Bio Edge shows a Certificate of Analysis on every product, and many can be confirmed at the issuing lab rather than taken on the vendor’s word: Kovera Labs reports resolve by their KVR code on Kovera’s public lookup, and MDx BioAnalytical Laboratory reports resolve by their COA identifier on MDx’s public CoA Search. Freedom Diagnostics (public accession lookup) and Janoshik reports appear as well. 228 of 475 certificate records carry a live provider-verification link, which is provider-verifiable public evidence rather than generic purity language.
Profile: bioedge-research-labs
Open profile Included because Peptide Sources publishes a broad product catalog with third-party certificates attached across most of its product pages.
A broad catalog with 141 public certificate-to-product relationships spanning 124 of 161 reviewed products. Most reports name Freedom Diagnostics or Bioviridian, average about 99.5% reported purity, and expose a public provider-verification path.
Testing transparency: Broad third-party COAs with public provider verification. Peptide Sources publishes 141 certificate-to-product relationships across 124 of 161 reviewed products. Of those, 129 are provider-verifiable relationships: Freedom Diagnostics reports with a public Search Code, Bioviridian reports whose printed codes resolve to laboratory-hosted certificates, and a Chromate report verified with its two-part public lookup. The remaining relationships are kept as source-linked documents rather than upgraded beyond what their verification path supports.
Tracked under the current dataset name "Peptides Source."

Open profile Included because Nura Peptide has a public storefront with openly visible pricing, branded product naming conventions, and COA language on the public site.
A mid-sized catalog with branded labels (GLP-3R, GLP-2T, GLP-1SG) spanning vials, nasal sprays, and capsules. Its gallery review retains 103 exact certificate-to-product relationships across 42 of 47 reviewed products, representing 94 distinct Freedom Diagnostics-named certificate origins.
Testing transparency: Freedom Diagnostics gallery; 93 of 94 certificate origins are provider-verifiable. 93 of the 94 distinct origins are provider-verifiable and account for 102 of the 103 product-certificate relationships. For those records, the exact Freedom code resolves and the provider document confirms both the code and Nura client identity. 1 source-attributed vendor image remains vendor-hosted because its code is not present in Freedom’s current index. At the relationship level, HPLC appears on 101 records, identity on 103, net content on 93, endotoxin on 42, and heavy metals on 6; none reports sterility.

Open profile Included because Pepora Labs runs a public storefront with openly visible pricing and exposes Freedom Diagnostics accession-verifiable COAs for its core range — an independent-provider lookup, stronger than downloadable PDFs or purity claims alone.
A small, focused catalog of single peptides plus branded blends (KLOW, GLOW, Wolverine, GLP-3). Dosage is encoded in the product SKU rather than the title. The highest-volume products (GHK-Cu, TB-500, Tesamorelin, Retatrutide) publish a Freedom Diagnostics batch accession and exact purity (HPLC + mass-spec identity) right in the product-page testing box, each searchable at FreedomDiagnosticsTesting.com.
Testing transparency: Freedom Diagnostics provider verification. Pepora’s core range carries Freedom Diagnostics accession-verifiable COAs — the batch accession, exact purity, and HPLC + mass-spec panels are exposed in product-page HTML with a public FreedomDiagnosticsTesting.com lookup. That is provider-verifiable public evidence, not just vendor-hosted documentation. The catalog is small, so this covers 4 of 11 products; the rest carry vendor-hosted Freedom Diagnostics PDFs without a public lookup.
Profile: pepora
Open profile Included because Glacier exposes both a public product catalog and a structured public COA archive — enough real evidence to compare it directly, after earlier confusion caused by a look-alike domain.
A stronger case than it first appeared. Glacier’s storefront routes visitors through a research-access gate, but its public COA archive holds per-lot Kovera Labs and Freedom Diagnostics reports — 46 of them independently verifiable at the testing lab, with archive purity averaging about 99.5% and endotoxin and heavy-metals results on most reports.
Testing transparency: Per-lot Kovera Labs & Freedom Diagnostics COAs with public provider verification. Glacier publishes a structured public COA archive (lot/date-level PDFs) whose reports are third-party — Kovera Labs (KVR verification code) and Freedom Diagnostics (public accession lookup). 46 lots carry a code that resolves on the testing lab’s own public verify surface, so this is outside-provider verification, not just vendor-hosted documentation. Average reported purity across the archive is about 99.5%; endotoxin appears on 76, heavy metals on 69 and sterility on 44 of 81 archive reports.

Open profile Included as VAYN (rebranded from His & Hers). Public storefront at vayn.co with live product pricing and a public /coas/ archive.
Rebranded from His & Hers to VAYN with the same products and formulas. Now at vayn.co with a clean public storefront and a public /coas/ archive — one page per batch. About half the archive is live-verified Chromate (RP-HPLC purity + identity); most of the rest resolves as Freedom Diagnostics provider objects with purity, identity, and net content. Reported purity averages around 99.3%.
Testing transparency: Public COA archive with Chromate and Freedom provider verification. VAYN publishes a public /coas/ index of batch-level pages. 45 retained reports identify Chromate and 38 identify Freedom Diagnostics; 83 certificate origins currently resolve through provider-controlled routes. Most documents report purity and identity, Freedom reports also carry net-content results, and 4 certificates report endotoxin. No current sterility or heavy-metals panel is inferred where a document does not report one.

Open profile Included because Silverstone Labs Co has a public storefront with openly visible pricing, branded GLP labels (SLP-2, SLP-3), and product-gallery certificates from third-party labs — ILS Laboratories, Kovera Labs, and Freedom Diagnostics — that include report-specific references to the issuing labs.
A compact public catalog with branded GLP naming (SLP-2, SLP-3) and core peptide coverage. The current product galleries expose 56 certificate records across 33 of 38 products in the certificate review, representing 50 distinct destination URLs. Of those, 38 are provider-verifiable relationships: ILS relationships carry report-specific links, Kovera relationships resolve at koveralabs.com, and Freedom relationships resolve at Freedom Diagnostics. Averaged purity runs ~99.7% with unusually broad safety panels — HPLC, identity, heavy-metals, endotoxin, and sterility.
Testing transparency: Public COA gallery with provider verification. Silverstone publishes 56 certificate records across 33 products, representing 50 distinct destination URLs.

Open profile Included because Ignite Peptides has a public storefront with openly visible pricing, branded GLP labels (GLP-1 (S), GLP-2 (TZ), GLP-3 (RT)), and a public COA Library of third-party Janoshik and Freedom Diagnostics reports.
A broad peptide catalog with branded GLP naming and core research peptides. Ignite publishes a dedicated public COA Library of third-party lab reports — led by Janoshik Analytical (HPLC purity), with Kovera Labs, Freedom Diagnostics, and ILS Laboratories reports — alongside product-gallery COA images.
Testing transparency: Public COA Library with Janoshik provider verification. Ignite publishes a public COA Library of third-party reports. A Janoshik report counts as provider-verifiable once its exact task-and-key route resolves at verify.janoshik.com: the library filename carries the task number and the report image prints the unique key. Kovera Labs codes open the report at Kovera’s verifier, and Freedom Diagnostics accessions resolve at the Freedom portal — 20 provider-verifiable reports in all. Reports back 20 of 28 reviewed products; the rest ship without a public certificate.

Open profile Included because Pepvida is a Canada-based storefront with a small, fully-priced catalog, branded product naming (RESET / HEAL / ATTRACT), and downloadable per-product COA PDFs with real purity figures.
A compact 10-product catalog with branded naming and dosages in the product titles. Pepvida is Canada-based (Ontario), ships to the US and Canada from Canadian warehouses, and lists prices in Canadian dollars — the pricing board converts those to USD so the comparison is apples-to-apples. Downloadable COA PDFs are published on a public lab-results hub.
Testing transparency: Testides provider verification COAs. Pepvida publishes downloadable COAs on a public lab-results hub. Each reviewed PDF carries an exact Testides report number; Testides’ public verifier independently confirms the matching legacy record plus its purity and total mass, while the vendor PDF remains the source for the compound, label claim, dates, lot details, and full certificate context. PeptideBenchmark requires those overlapping values to agree before recording the relationship as provider-verifiable.
Profile: pepvida
Open profile Included because Regenerative Research pairs a clean headless storefront (live price and mg dosage exposed per product) with a downloadable third-party Certificate of Analysis on nearly every peptide, a portion of them carrying independent provider verification.
A focused peptide catalog on a modern headless storefront with transparent per-mg pricing, and a per-batch Certificate of Analysis linked to 25 of its 30 products — a mix of Krause Analytical, ILS Laboratories, Freedom Diagnostics, and BTLabs reports covering purity, identity, endotoxin, sterility, and heavy metals.
Testing transparency: Per-product third-party COAs, some with public provider verification (ILS Laboratories, Freedom Diagnostics). Every peptide links a downloadable third-party COA reporting HPLC purity, identity, endotoxin, sterility, and heavy metals, plus a controlled-substance contaminant screen. The lab mix is uneven: many certificates are vendor-hosted PDFs from named labs (Krause Analytical, BTLabs), while ILS Laboratories COAs (access code independently verifiable at ils-lab.com) and Freedom Diagnostics (public accession) are provider-verifiable.

Open profile A Southeast Texas research storefront with openly listed single-vial prices and a public collection of Freedom Diagnostics certificates, including reports verified at the laboratory under the Legendary Peptides client name.
Legendary Peptides sells research-only singles and blends with prices on the product pages, including house codes GLP2 (T) for tirzepatide and GLP3 (R) for retatrutide, plus GLOW/KLOW, BPC/TB, CJC/IPA, and Tesamorelin/Ipamorelin blends. Its public certificate library contains Freedom Diagnostics reports; PeptideBenchmark checks printed Search Codes at Freedom and confirms the Legendary Peptides client name. Current certificate-to-catalog relationships are counted only where independently confirmed. Ten-vial kits, bacteriostatic water, LIPO-C+, and L-Carnitine stay outside the retail single-vial board.
Testing transparency: Public Freedom Diagnostics certificate library with provider verification. The public certificate library includes Freedom Diagnostics reports verified under the Legendary Peptides client name. Reports typically support identity, HPLC purity, net content, and endotoxin for the named sample. We have not verified every current catalog relationship; an unresolved relationship does not mean the vendor lacks a certificate link. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profile Included because Midwest Peptide pairs an openly priced catalog with product-level ILS Laboratories and Freedom Diagnostics certificates that can be checked independently at the issuing laboratory.
Midwest Peptide publishes product-level certificates from ILS Laboratories and Freedom Diagnostics. The current review covers every in-scope catalog product, with exact provider verification and separate reporting of purity, identity, net content, and any safety panels present on each certificate.
Testing transparency: Per-product ILS and Freedom Diagnostics COAs with provider verification. The current review retains 34 distinct certificates across all 30 in-scope catalog products: 21 Freedom Diagnostics reports and 13 ILS Laboratories reports. Each has an exact laboratory verification route. Results and safety panels remain specific to the individual certificate; a reported endotoxin value is not labeled a pass unless the report states that conclusion.

Open profile A Missouri-stated research storefront with public single-vial prices and a public certificate index whose reports link directly to Freedom Diagnostics under the Midwest Compounds client name.
Midwest Compounds lists a small catalog of single-vial research peptides with prices on the product pages, including the house name BB for a BPC-157 and TB-500 blend. The public COA index links each published batch to a Freedom Diagnostics report. PeptideBenchmark uses the regular list price and keeps free shipping over $150 as a vendor-stated checkout term.
Testing transparency: Public COA index with Freedom Diagnostics provider verification. The public COA index links each published batch to a report hosted at Freedom Diagnostics that resolves under the Midwest Compounds client name, supporting identity, HPLC/LC-MS purity, and net content. A strength-specific report is not treated as testing every other strength, and storefront purity marketing is not inherited onto sterility or endotoxin panels the reports do not run.

Open profile A broad WooCommerce storefront that pairs a large research-peptide catalog with a per-product third-party COA gallery — HPLC purity plus USP safety panels on many products.
One of the wider curated catalogs — branded GLP agonists across many dosages, recovery blends, and a full run of Khavinson bioregulators — where covered products ship their own gallery of third-party COA images from Vanguard Laboratory (ISO 17025 HPLC-UV/VIS purity + quantity) and Janoshik Analytical, alongside USP <85> endotoxin and <71> sterility panel scans. Purity runs consistently high and safety-panel coverage is unusually complete.
Testing transparency: Per-product third-party COA gallery (Vanguard / Janoshik) with USP safety panels. In-scope products publish galleries of third-party COA images: Janoshik Analytical and Vanguard Laboratory HPLC-UV/VIS purity and quantity reports plus USP <85> endotoxin, <71> sterility, and <61> microbial panel scans. Janoshik reports that print a unique key can be checked at janoshik.com/verify, while the Vanguard COAs are named accredited-lab documents without a public verification portal.

Glow Aminos (glowaminos.com) is a members-only research catalog, distinct from Glow Peptides (glowpeptides.com). List prices are visible after researcher login. House labels FG1-S, FG2-T, and FG3-R map to semaglutide, tirzepatide, and retatrutide. Most lots check out at ILS Laboratories under client Glow Aminos, with additional Chromate reports.
Testing transparency: ILS and Chromate provider verification; certificate index requires a researcher account. Current-batch and previous-batch certificate pages require a Glow Aminos researcher account. Once opened, most lots resolve at ILS Laboratories under client Glow Aminos (HPLC, identity, endotoxin, sterility, and net content), and Chromate Job+Access pairs resolve at chromate.org.

One of the deeper public certificate trails in the catalog: a /lab-results/ library of 174 distinct COAs across the range, 119 of which resolve at the issuing lab’s own portal (41 Janoshik Analytical, 40 Chromate, 36 Freedom Diagnostics and 2 TrustPointe Analytics). Reported purity averages about 99.4%, and 51 of the reviewed certificates report endotoxin, 50 heavy metals and 22 sterility. A further 43 vendor-hosted Vanguard Laboratory COAs count as named-lab evidence.
Testing transparency: Third-party Janoshik, Chromate + Freedom Diagnostics COAs with public provider verification. RUO’s public /lab-results/ library links per-product COAs. Janoshik reports are checked two-factor at verify.janoshik.com by task number plus unique key, Chromate certificates at chromate.org by job number plus access code, Freedom Diagnostics PDFs at the lab by accession, search code, client and lot, and TrustPointe PDFs by their Verification Key — 119 certificates across the catalog (41 Janoshik Analytical, 40 Chromate, 36 Freedom Diagnostics and 2 TrustPointe Analytics) were confirmed live this way before being recorded, so those can be checked at the lab rather than taken on the vendor’s word. The 43 vendor-hosted Vanguard Laboratory PDFs count as named-lab evidence, not provider-verifiable: Vanguard runs an opt-in public database at verifiedbyvanguard.com, and none of RUO’s Vanguard Laboratory IDs is listed there.

Open profile A registration-gated storefront that nonetheless publishes one of the deepest public COA archives in the catalog — 134 reviewed TrustPointe Analytics Certificate-of-Analysis reports, the recent batches independently verifiable at the lab's own portal — paired with transparent per-mg pricing.
A broad injectable peptide catalog backed by a public WordPress lab-report archive of batch-level TrustPointe Analytics COAs. TrustPointe certificates print a Verification Key, and 121 reports have been confirmed live at trustpointelims.com, so a reader can check those at the lab rather than taking the vendor's word. 127 of the 147 reviewed archive reports include an endotoxin result.
Testing transparency: Third-party TrustPointe Analytics COAs with public provider verification. Skye publishes a public lab-report archive whose COA PDFs are mostly TrustPointe Analytics reports (134 of 147); a TrustPointe report prints a Verification Key that resolves at trustpointelims.com while its batch is in the public portal. The recent batches were confirmed live at the portal before being recorded as provider-verifiable — the report is reached at the lab, not just hosted by the vendor. Older batches rotate out of the public portal but remain published as named-lab TrustPointe documents, and the verified share grows weekly as new batches are checked.

Open profile A Las Vegas storefront that backs much of its catalog with third-party Freedom Diagnostics COAs — every certificate independently confirmable at the lab, at near-99.7% reported purity — paired with transparent per-mg pricing.
A broad injectable peptide catalog whose covered products link a downloadable Freedom Diagnostics Certificate of Analysis carrying a public Accession # and Search Code. Every certificate was two-factor confirmed — the vendor's copy is matched against Freedom's own portal record, with the client, search code, accession, and lot cross-checked between the two (and nearly all are byte-identical) — so a reader can verify the report at the lab rather than trusting the vendor's upload. Reported purity averages about 99.7%, with identity, net-content, and endotoxin results on many batches.
Testing transparency: Per-product Freedom Diagnostics COAs with public provider verification. Protide publishes a per-product COA archive whose certificates are Freedom Diagnostics reports; each prints an Accession # and Search Code that resolve at FreedomDiagnosticsTesting.com. Every certificate was confirmed live against the provider's own copy before being recorded as provider-verifiable — the report is reached at the lab, not just hosted by the vendor. The current set reports identity, HPLC purity, net content, and frequent endotoxin results; 17 current reports also include heavy-metals results, while panel coverage remains certificate-specific.

Most of the injectable catalog links a downloadable Certificate of Analysis issued by a third-party lab. Horizon Analytical reports (purity by UPLC/MS plus a separate endotoxin certificate) resolve by lot number at horizonanalytical.com; ILS Laboratories reports (HPLC purity and identity, net-peptide content, and endotoxin) resolve by COA number at ils-lab.com. 33 of 101 certificate records were two-factor confirmed — the vendor's lot or COA number is resolved against the lab's own public record and the returned client name is matched to Northline Labs — so the report is reached at the lab, not just hosted by the vendor. Reported purity runs near 99.5%.
Testing transparency: Per-product Horizon Analytical and ILS Laboratories COAs with public provider verification. Tested products link a vendor-hosted COA PDF issued by Horizon Analytical or ILS Laboratories. Each provider-confirmed Horizon lot (NLL-…) is searchable at horizonanalytical.com and each ILS COA number resolves at ils-lab.com; both return the report under the Northline Labs client name, so a reader can confirm the certificate at the issuing lab rather than trusting the vendor's upload.

ILS reports have exact public verification links; Vanguard reports are checked against the laboratory’s matching public documents when available. Other published Vanguard reports remain vendor-document evidence.
Testing transparency: Per-product ILS and Vanguard COAs with report-specific provider verification. Product pages link downloadable ILS Laboratories and Vanguard Laboratory certificates. Provider verification applies only to reports confirmed by the named laboratory; vendor-published certificates without a matching public laboratory record stay visible without that badge. Results reported as thresholds remain thresholds rather than exact percentages.

Open profile A Boca Raton storefront whose peptide catalog is testing-forward: product pages embed a named-accredited-lab Certificate of Analysis whose report IDs also resolve at the lab’s own public verification portal, layered over openly visible per-mg pricing.
A public WooCommerce catalog where product pages carry per-product Vanguard Laboratory COA images reporting HPLC purity plus endotoxin, sterility, and heavy-metals panels. What lifts it above vendor-hosted documents is that the same Vanguard report IDs are published to Vanguard’s own public COA portal, so a reader can pull the certificate straight from the lab rather than trusting a vendor-hosted image.
Testing transparency: Vanguard Laboratory COAs with public provider verification. Licensed Peptides embeds per-product Vanguard Laboratory COA images (HPLC chromatographic purity near 99.4%, with endotoxin, sterility, and heavy-metals panels on many batches) and publishes the same certificates to Vanguard’s public COA portal (verifiedbyvanguard.com) under the brand it registered there, so the report IDs resolve to lab-hosted PDFs a reader can verify independently. Vanguard is an ISO 17025:2017 / A2LA-accredited US laboratory (Certificate #6377.01.01).

The Peptides Collective publishes an openly priced research-peptide catalog and a public Lab Reports grid of batch cards with downloadable COA PDFs. Branded GLP aliases (GLP-3/R, GLP-1/S, GLP-2/T) map to retatrutide, semaglutide, and tirzepatide for $/mg comparison; named blends such as KLOW, GLOW, Selank+Semax, and Ipamorelin+Tesamorelin use their labeled vial totals. Most certificates are Janoshik Analytical TEST REPORTs; a Chromate subset prints job and access codes for independent portal checks when the provider resolves.
Testing transparency: Public Janoshik + Chromate COA archive with provider verification. The public /lab-report/ page lists batch cards with purity, lot, date, and View COA PDF links under wp-content/uploads. Credentials are read from each PDF and confirmed at Janoshik or Chromate when the portal accepts the pair; documents that name a lab but do not currently resolve stay as named-lab, vendor-hosted evidence rather than provider-verified.

SKO Compounds sits behind a 21+/research-use overlay that gates the rendered page but not the underlying data: the site's own content-hashed JavaScript bundle embeds the full product catalog (name, dosage ladder, per-dosage price, stock, and COA PDF path), and a public Supabase RPC exposes live stock overrides — both readable with a plain unauthenticated fetch. PeptideBenchmark normalizes 32 in-stock dosage rows to $/mg and processed 35 recovered Freedom Diagnostics COA PDFs, current and retained prior-batch: every one carries a FreedomDiagnosticsTesting.com letterhead, and 33 verify independently under the SKO Compounds client name at the lab's own public certificate lookup. 11 products are marked "Coming Soon" on SKO's own /coas page and recorded as an explicit testing gap rather than silently dropped.

Every COA PDF URL is read directly out of SKO's own product bundle (current and retained prior-batch fields), downloaded, and text-extracted rather than guessed from a gallery image. Of 35 recovered Freedom Diagnostics PDFs, 33 resolve live at the lab's public lookup under the "SKO Compounds" client name, reporting HPLC purity (averaging about 99.7%), identity, net content, and endotoxin on applicable batches. The remaining Freedom documents no longer resolve and remain named-lab evidence. ILS Laboratories is named on 6 separate current certificates, including Kisspeptin, reporting identity, purity, net content, endotoxin, sterility, and heavy metals; because none has a confirmed provider route, those panels remain document-extracted rather than provider-verified.

Open profile A Spokane, Washington research supplier with a small public catalog, free domestic shipping on every order, and a Lab Results page whose Janoshik Analytical reports check out on the lab's own verify site.
Cinder Peptides keeps a compact research-only catalog — BPC-157, GHK-Cu, GLOW, branded GLP-2/GLP-3 strengths, and a handful of still-building SKUs — with openly listed vial prices and quantity discounts. Its public Lab Results page links Janoshik reports for the tested products; PeptideBenchmark confirmed those reports live at the lab during onboarding.
Testing transparency: Public Janoshik COA index with provider verification. The public Lab Results page and product pages link Janoshik Analytical reports that readers can open on the lab's own verify site. Products still marked Coming soon on Lab Results are recorded as explicit testing gaps rather than inferred coverage.

Open profile An Austin-mailed U.S. research storefront with openly listed single-vial prices and a public COA library of vendor-hosted laboratory PDFs. Those documents resolve at named labs (Janoshik, Freedom, MZ Biolabs, Waiida) but currently print OEM/wholesale client names rather than Core Research Peptides — a different company from curated Vital Core Research.
Core Research Peptides sells a compact research-only catalog with prices on the product pages, including multiple Retatrutide strengths and common singles. Its public COA library hosts downloadable laboratory PDFs. PeptideBenchmark opens those files and checks Janoshik task/key routes and the Freedom index where codes exist; the reports’ own client fields name other accounts, so they stay named-lab public documents rather than vendor-client–matched verification. Reconstitution solution remains outside Pricing; hCG 5,000 IU appears in IU hormones.
Testing transparency: Public COA archive. The public COA library hosts vendor-hosted laboratory PDFs that readers can download. Janoshik task/key pairs and a Freedom Search Code can be checked at those laboratories’ public surfaces, but the printed client names are OEM/wholesale accounts rather than Core Research Peptides. Library rows still marked pending are recorded as testing gaps. A matched document describes the tested sample and does not endorse every vial or unlisted safety panel.

Open profile A Wyoming research supplier with a large openly priced peptide catalog, a public COA page, and ILS Laboratories plus Freedom Diagnostics reports that check out at the labs under the Premier Bio Labs name.
Premier Bio Labs sells a broad research-only range — singles, blends, and multi-vial kits — with prices listed on the product pages. Its public COA page and product photos link ILS and Freedom Diagnostics reports; PeptideBenchmark confirmed those reports live at the labs during onboarding. Branded GLP-1/2/3 and house blends (GLOW, KLOW, Wolverine) are mapped from the vendor's own labels.
Testing transparency: Public COA archive with ILS and Freedom provider verification. The public COA page and product galleries link ILS Laboratories and Freedom Diagnostics reports that readers can check on the labs' own verify pages. Safety-panel depth is strong on the current set (identity, HPLC, endotoxin, and often sterility/heavy metals).

Open profile A Los Angeles–branded research storefront (ngpeptide.com) with openly listed vial prices and a public COA library of ILS Laboratories PDFs that resolve at portal.ils-lab.com under the NextGen Peptides client name — distinct from the separately curated NextGenPeps brand.
NextGen Peptides sells research-only singles and blends with prices on the product pages, including branded TRZ/GLP-3 strengths and GLOW/KLOW blends. Its public COA library hosts batch PDFs; PeptideBenchmark confirmed the embedded ILS verify links live at the lab under client NextGen Peptides. Comparable capsules and ready sprays appear in their format-specific Pricing lanes; oral drops and multipacks remain outside current supported comparisons.
Testing transparency: Public COA archive with ILS provider verification. The public COA library links vendor-hosted PDFs. Most reviewed certificate origins carry exact ILS provider tokens and client matches that readers can open on portal.ils-lab.com; a small remainder is retained only as vendor-certificate links and is not treated as provider-verified. Safety-panel depth is strong on the current set (HPLC, identity, endotoxin, sterility, and often heavy metals / net content). A few library UI labels name other labs while the PDF itself is ILS — the PDF/provider route is the source of truth.

Open profile A U.S.-based research supplier with openly listed vial prices across a compact catalog and a public COA page of Freedom Diagnostics–labeled reports that can be opened and cross-checked against Freedom’s public index — though the reports themselves name wholesale/reseller client accounts rather than Nation Peptides.
Nation Peptides sells research-only singles and blends with prices listed on the product pages, including branded GLP-1/2/3 strengths and a Glow blend. Its public COA page hosts Freedom Diagnostics–labeled certificates for much of the peptide range. Those documents resolve on Freedom’s public index, but they are filed under generic wholesale client names (not Nation Peptides), so PeptideBenchmark treats them as named-lab public documents rather than vendor-client–matched verification.
Testing transparency: Public Freedom-labeled COA archive. The public COA page hosts Freedom Diagnostics–labeled PDFs and images that readers can download. The documents resolve on Freedom’s public index, but their own client fields name wholesale/reseller accounts rather than Nation Peptides. Product-page “Verify on Lab Site” buttons that point to a different brand’s website are not treated as laboratory verification.

Wholesale 10-vial multipacks stay outside the retail single-vial board.
Testing transparency: Public COA archive with Freedom Diagnostics provider verification. The public certificate-of-analysis library hosts Freedom Diagnostics PDFs that resolve at the laboratory’s public verification surface when the printed client is NuLab Peptides or Nu Lab Peptides. Downloadable certificates cover a subset of listed strengths; additional library entries remain marked Coming soon until a PDF is published. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Certificate PDFs are publicly linked from product galleries and the WordPress media library. 65 current report origins resolve through provider-controlled routes, while 36 vendor-hosted images or PDFs remain source-linked without an independent-verification badge. The retained documents broadly report identity, HPLC purity, and net content; endotoxin results appear on 31 reports, sterility on 31 and heavy metals on 31, which PB keeps certificate-specific rather than applying across the catalog.

Open profile Historical evidence from a former Sacramento research storefront with openly listed vial and kit prices and a dense public Janoshik Analytical certificate trail on the homepage and /testing/ page, including house-code GLP strengths that resolve to named compounds via product-page CAS numbers and lab report labels.
The official site announces permanent closure, observed September 30, 2026; the notice does not state a closure date. Retained prices are historical and excluded from current Pricing and Stack Builder. Its former storefront sold research-only singles and blends, including house codes GLP-1S / GLP-1T / GLP-1C / GLP-3 for semaglutide, tirzepatide, cagrilintide, and retatrutide, plus Peptide-31 for SS-31 and GLOW / KLOW blends. The preserved certificate archive includes its formerly published Janoshik Analytical links and COA images. Legal entity Origin Sourcing Group LLC publishes a Sacramento, California fulfillment address.
Testing transparency: Retained Janoshik report and verification evidence. The current archive retains distinct certificate origins from Janoshik Analytical, Vanguard Laboratory, and MZBiolabs alongside a small unidentified-laboratory set. Exact Janoshik test routes account for the independently provider-verifiable evidence; the remaining origins are retained as vendor-hosted COA images without inheriting a provider-verification badge. PB extracts panel-level evidence from each matching record, including HPLC, identity, net content, endotoxin, sterility, and heavy metals only where that result is reported.

Open profile A US-shipping research storefront with an openly priced kit catalog and a dedicated lab portal whose active-batch reports largely resolve to Janoshik Analytical, including vendor mirror pages that disclose the tested compound by name in their own results.
Nexaph sells research-only singles and blends as fixed 10-vial kits, including house codes NXP-1P / NXP-2P / NXP-3P for semaglutide, tirzepatide, and retatrutide, plus a GHK-Cu/KPV beauty blend and a BPC-157/TB-500 blend. Its lab portal lists one active batch per catalog strength; most resolve through vendor mirror pages that name the compound directly in their own Mass/Purity results alongside Sterility, Endotoxin, and Heavy Metals panels, and the rest link straight to Janoshik.
Testing transparency: Public lab portal linking Janoshik Analytical reports. The lab portal publishes the full batch history for each catalog strength — the currently active certificate plus every previous version still retained — and PeptideBenchmark ingests all of them. 317 of 323 reports resolve to Janoshik Analytical either directly or through a vendor mirror page that discloses the tested compound by name along with Sterility, Endotoxin, and Heavy Metals results for the same batch; for the other 6 portal entries, the purity report carries no Janoshik task and key. PeptideBenchmark independently confirms the distinct Janoshik task/key routes at the laboratory and re-checks them on the normal trust cadence.

Open profile A Wellington, Florida research storefront that publishes an ILS Laboratories certificate for every peptide it sells and puts its prices behind a free researcher account. Certificate coverage is complete and each lot verifies at the laboratory as well as on the vendor’s own site, but the catalog is one batch series old and the business itself is only a few months old.
PADRE Research sells 8 peptides, and 8 carry a certificate of analysis from ILS Laboratories drawn from its first batch series. PeptideBenchmark checked each one twice: the certificate PADRE serves from its own storage, and the same report resolved at the laboratory’s public portal from the access code printed on it. Every lot resolves under the client name Padre Research, and the two copies are byte-identical. Reported purity averages about 99.7%, and each report covers HPLC purity and identity, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and a quantitative endotoxin result. Prices and the certificate index require a free account; the certificate documents themselves are served publicly.
Testing transparency: Public COA archive with ILS provider verification. Every peptide in the catalog has a certificate, and every certificate is independently checkable: the printed access code resolves at ILS Laboratories’ own portal under the client name Padre Research, returning the same report PADRE publishes. Coverage is complete for the current catalog but shallow in time — every reviewed lot comes from the vendor’s first batch series, tested in July 2026, so there is no batch history to compare against yet. One qualification on the accreditation PADRE cites: ILS holds a current ISO/IEC 17025:2017 accreditation from PJLA, but its scope covers cannabis and hemp testing rather than peptide analysis, so it should not be read as extending to the panels on these certificates. That applies to every vendor using this laboratory, not only PADRE.

Open profile A Burbank-mailed research storefront with public single-vial pricing, a mixed-or-repeated bundle builder, and a public certificate registry whose Freedom Diagnostics and ILS Laboratories documents resolve to exact laboratory records.
NovaForge Labs publishes a compact research catalog with live prices and stock state, including tirzepatide and retatrutide, previously listed under the house labels Dual-Agonist and Triple-Agonist. PeptideBenchmark tracks comparable single-vial offers, models the public three- and five-item builder separately, routes nasal sprays to the non-vial inventory, and keeps first-order, returning-customer, referral, rewards, and public affiliate-program offers outside default ranked prices.
Testing transparency: Public Freedom Diagnostics + ILS provider verification. The public COA registry retains current and prior Freedom Diagnostics and ILS Laboratories reports. At the September 30, 2026 recheck, all 27 credited documents resolved at the issuing laboratory: most vendor/provider pairs were byte-identical, while a few ILS provider files had reviewed QR-code revisions with unchanged report text and results. The vendor originals remain preserved. 2 early Freedom reports print the unexplained client spelling NovsForge Labs; PeptideBenchmark accepts only that exact reviewed alias. Published reports support identity, HPLC purity, and net content for the named samples; panel credit stays document-specific. ILS has current ISO/IEC 17025 accreditation, but its published scope covers cannabis/hemp testing rather than peptide analysis.

Open profile An Anchorage, Alaska research storefront with public single-vial and multi-vial pricing plus a batch-report library containing exact ILS Laboratories and Janoshik Analytical records. The profile retains dated receipts for historical document mismatches, separately from the certificates Arctic currently publishes.
Arctic Lab Supply publishes standing single-vial and multi-vial prices; PeptideBenchmark tracks its peptide catalog. An October 3, 2026 availability check found reconstitution solution on a documentation hold and the empty spray bottle removed from sale. House labels GLP-1 (SG), GLP-2 (TR), and GLP-3 (RT) map to semaglutide, tirzepatide, and retatrutide. Current ILS and historical Janoshik documents in the public batch archive resolve at the issuing laboratories under Arctic Lab Supply. Historical images reviewed in September used a Chromate credential that identified MOB Peptides and GHK-Cu 50mg. By October 3, 2026, Arctic had removed those images from its archive and their source URLs returned not found. The original mismatch receipts remain excluded from evidence credit; removal does not resolve the historical discrepancy.
Testing transparency: Public ILS + Janoshik verification; dated mismatch history retained. PeptideBenchmark confirms current ILS reports through exact public routes and historical Janoshik reports through exact task/key routes under the Arctic Lab Supply client name. The ILS records report HPLC purity, identity, endotoxin, and net content, with some also reporting sterility and heavy metals. Historical images formerly hosted by Arctic remain in the internal review ledger with their original September observation dates: their Chromate credentials identified MOB Peptides / GHK-Cu 50mg. An October 3, 2026 check confirmed that the images were no longer published and their source URLs returned not found. They remain excluded from public certificate records and scoring. A matched certificate documents only the tested sample and listed panels, not every vial or catalog item.

Open profile A Cumming, Georgia research storefront operated by Mira Labs LLC, with public per-vial prices and a public certificate library of lot-level BTLabs reports plus an ILS Laboratories record that resolves under the Curo client name.
Curo publishes a compact research catalog with live prices for each labeled strength, including the house name RTA-GLP3 for retatrutide and Epithalon for the canonical Epitalon lane. PeptideBenchmark tracks the peptide vials and leaves bacteriostatic water, acetic acid, and the vial case off the board. All 19 BTLabs files in the public library, including the endotoxin reports, were checked against the laboratory PDF under the customer name CURO. The ILS record for KLOW 80mg also resolves under Curo.
Testing transparency: Public BTLabs and ILS records with laboratory checks. The public COA library lists 19 BTLabs reports and 1 ILS Laboratories portal record. On October 3, 2026 PeptideBenchmark checked every BTLabs file at the laboratory: page links for the identity reports, and the QR code printed on each endotoxin report. Each laboratory PDF names customer CURO and the paired product. The ILS link for KLOW 80mg also resolves under Curo. A matched certificate covers the tested sample and the panels printed on that document.

Novaglo Research publishes standing prices for single vials and fixed multi-vial lab bundles. GLP-3 RT, GLP-2 TZ, and GLP-1 SE are the storefront names for retatrutide, tirzepatide, and semaglutide. The public certificate archive pairs each lot page with a Freedom Diagnostics image. PeptideBenchmark checks the search code printed on the image against the laboratory copy when that copy names Novaglo. Comparison prices use the regular price; an anniversary markdown was on the storefront on September 23, 2026 and is not the standing board price.
Testing transparency: Public Freedom Diagnostics archive with provider verification. Each public certificate page names Freedom Diagnostics and shows a certificate image. PeptideBenchmark reads the search code on the image and checks the laboratory-hosted copy when it names Novaglo Research.

GLP-1 R, GLP-1 T, and GLP-1 S are the storefront codes for retatrutide, tirzepatide, and semaglutide. Vial certificates are Vanguard Laboratory PDFs under the Hello Stacks client name. StackOne pen and refill certificates are Freedom Diagnostics PDFs under the Stack One Labs client name. HGH is sold in IU. Reconstitution solution and the empty pen stay off the peptide board.
Testing transparency: Public Vanguard and Freedom Diagnostics COAs with provider verification. Vial lots link a Vanguard Laboratory PDF. PeptideBenchmark checks the laboratory ID on that PDF against Vanguard’s public certificate database when the laboratory copy names Hello Stacks. StackOne pen and refill lots link a Freedom Diagnostics PDF. PeptideBenchmark checks the printed search code against Freedom’s copy when that copy names Stack One Labs. A matched certificate documents the tested sample and the panels printed on that document. It does not cover a product that has no certificate, and it is not a sterility or heavy-metals finding unless the document reports those assays.

Open profile An Orlando-stated research storefront with openly listed single-vial prices and a public certificate archive of Janoshik report images. Those documents resolve at Janoshik under the manufacturer client Cocer Peptides, not under Lyra Vital.
Lyra Vital sells a compact research-only catalog with a price on every size, including branded blends (Glow, Wolverine) and common singles. Each compound page links a public certificate table of current and older batches. The report images are Janoshik Analytical certificates. PeptideBenchmark reads those images and checks the task and key at Janoshik; the client field names Cocer Peptides, the manufacturer Lyra Vital says commissioned the tests. Bacteriostatic water stays off the peptide board.
Testing transparency: Public COA archive. Each compound has a public certificate table with a vendor-hosted report image and a Janoshik task and key. Readers can open the laboratory route themselves. The printed client is the manufacturer, Cocer Peptides, not Lyra Vital, so these stay named-lab public documents rather than vendor-client–matched verification. A matched document describes the tested sample and the panels printed on it. It does not endorse every vial, and measured content on a certificate can differ from the labeled retail fill.
