Curated Research Vendors

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.

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.

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.

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.

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.

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 30 public product parents, 49 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.

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 9, 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Included because Voltera Sciences has a public storefront with openly visible pricing, branded product naming (VLS-3RT, VLS-2TRZ), and a focused peptide catalog.

A compact, focused catalog with branded GLP labels (VLS-3RT, VLS-2TRZ) mapped on the pricing board and standard peptide offerings. Public storefront with openly visible pricing.

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.

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 October 9 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.

A New Jersey research storefront with public vial prices and a large certificate library; many reports can be checked at North American Diagnostics under ProSupply Peptides | pspeptides.com.

PS Peptides lists single-vial research peptides with milligram options on the public catalog. The certifications page publishes laboratory PDFs for current and older batches. Ranked prices apply the cart-checked code BENCHMARK, 10% off the regular list price. The referral link records the visit and does not apply that discount by itself.

Included as a broad public catalog with product-level certificates spanning several named outside laboratories and live provider verification for many current reports.

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.

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.

A Delaware-registered research storefront with openly listed vial prices and a public /coa/library of per-lot certificates from AV Analytics, Chromate, Freedom Diagnostics, and Bioviridian — with Chromate and Bioviridian reports independently checkable at the laboratories.

Bench Grade Peptides sells research-only singles and blends with prices on the catalogue, including house codes GLP-1 S for semaglutide, GLP-2 T for tirzepatide, GLP-3 R for retatrutide, and AMY-A for cagrilintide, plus GLOW/KLOW and BPC/TB and CJC/IPA blends. 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.

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.

Tracked under the shorter dataset name "Blank."

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.

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.

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.

Tracked under the current benchmark dataset name "Pure Peptides Bio."

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.

Tracked under the current dataset name "PeptidePlugs."

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.

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.

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.

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.

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.

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.

Included because it ranks highly on the board and now has a real trust-review surface rather than just a score-driven placeholder.

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.

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.

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.

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.

Tracked under the current benchmark dataset name "Genpeptide."

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.

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.

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.

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.

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.

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.

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.

Included because Nationwide is a disclosed affiliate relationship and exposes a public WooCommerce storefront plus 91 attributable Freedom Diagnostics certificates across 47 current products. 87 resolve to exact laboratory-owned report objects; 4 remain preserved vendor copies whose corresponding provider URLs currently return 404.

A public catalog with clearly listed products, live variable-product pricing, and 91 downloadable Freedom Diagnostics certificates across 47 products. The reviewed documents average about 99.5% HPLC-UV purity and report identity and net content; 87 have exact laboratory-controlled verification routes.

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.

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.

Included because LA Peptides pairs a broad catalog, compared on the pricing board, with certificates that readers can confirm at the issuing laboratory: Bioviridian Inc. Web Verification Codes at bioviridians.com and Freedom Diagnostics report codes at that laboratory’s own lookup.

LA Peptides rebuilt its storefront in early October 2026. Every page, including product pages and prices, now opens only after a free members sign-up that asks visitors to confirm they are 21 or older and buying for research use. The pricing board compares 57 offers from LA Peptides’ catalog. In PeptideBenchmark’s certificate record, last reviewed October 6, 2026, 134 of 153 certificate-to-product relationships were verified at the issuing laboratory; the record also keeps entries from LA Peptides’ previous site, which no longer serves them. Reported purity averages about 99.7%.

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.

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.

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.

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.

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.

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.

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.

Included because Vital Core Research has a public Woodmart/WooCommerce storefront with live variation pricing and COA image assets embedded directly in product galleries.

A public storefront with live variation pricing and COA images embedded directly in product galleries, making its named-lab documentation easy to inspect alongside the relevant products.

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 or ILS certificates — the rest show "COA Coming Soon".

Included because IDUN Peptides has a perfect Peptide Critic score and a public COA Library page with extensive certificate-of-analysis documentation.

A focused catalog with competitive pricing, strong COA branding, and a dedicated public COA Library.

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.

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.

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.

Included because Peptide Sources publishes a broad product catalog with third-party certificates attached across most of its product pages.

A broad catalog with 140 public certificate-to-product relationships spanning 123 of 160 reviewed products. Most reports name Freedom Diagnostics or Bioviridian, average about 99.5% reported purity, and expose a public provider-verification path.

Tracked under the current dataset name "Peptides Source."

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.

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.

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.

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%.

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.

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.

Included because Panda Peptides (Xylo Research Systems LLC) has a public storefront with openly visible pricing, branded GLP labels (GLP-1S, GLP-2, GLP-3), and a public /coa/ archive with Janoshik verification links.

A research peptide catalog operated by Xylo Research Systems LLC with branded GLP naming, core peptides, and a public COA archive at /coa/. Product pages and the archive expose Janoshik verify links plus vendor-hosted COA images.

Included because Southern Aminos has a public storefront with openly visible pricing, branded GLP labels (SA-2T, SA-3R, SA-4C), and embedded ILS Labs COA tables with portal verification links on product pages.

A research peptide catalog with branded GLP naming, broad vial coverage, and unusually deep per-product COA tables. Product pages publish batch-level purity, 8X testing panels, ILS Labs PDF reports, and portal verification links rather than generic quality copy alone.

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.

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.

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.

A U.S. WooCommerce storefront that publishes a central Freedom Diagnostics COA gallery — provider-verifiable, search-code testing on its core peptides — paired with transparent per-vial and per-mg pricing.

A focused research-peptide catalog spanning the mainstream GLP agonists, recovery blends, GHK-Cu and a growing set of bioregulators. Its core peptides carry Freedom Diagnostics certificates in a central COA gallery — quantitative HPLC-UV purity, LC-MS identity, and net-content fill — and 8 of 10 certificates print a Freedom Search Code that resolves at the lab's public portal. Measured purity runs high (roughly 99.5% on average).

A U.S. research storefront with openly listed vial prices and a public certificate archive whose Kovera Labs and Freedom Diagnostics reports resolve at the laboratories’ public verification surfaces under the Lost Coast Aminos client name.

Lost Coast Aminos sells research-only singles and blends with prices on the product pages, including house codes LCA-SM / LCA-T2 / LCA-R3 for semaglutide, tirzepatide, and retatrutide, plus GLOW/KLOW, Wolverine-style BPC/TB blends, and other research compounds. The public /coa/ archive publishes certificate images; PeptideBenchmark confirms printed Kovera report codes and Freedom Search Codes against each laboratory’s public lookup where the client field names Lost Coast Aminos. Temporary sale prices are captured separately from the regular list price used on the pricing board.

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.

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.

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.

A U.S. research storefront whose catalog and certificate index sit behind a researcher account, distinct from Glow Peptides. Included so readers can compare FG-series vials on price and check ILS / Chromate lot paperwork.

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.

A modern storefront that backs most of its injectable catalog with per-lot Freedom Diagnostics COAs — provider-verifiable third-party testing paired with transparent per-mg pricing.

A focused peptide catalog where most vials are covered by a per-lot Freedom Diagnostics Certificate of Analysis — quantitative HPLC-UV purity, LC-MS identity confirmation, endotoxin screening, and net-content fill accuracy. Purity averages about 99.7%, and 46 of 50 certificates carry a Freedom Search Code that resolves at the lab's public portal.

A registration-gated storefront that nonetheless publishes a fully public /lab-results/ COA library, 119 of its 174 certificates resolving at the issuing lab’s own portal, paired with transparent per-mg pricing.

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.

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.

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.

A WooCommerce storefront whose tested products carry downloadable third-party COAs from independently queryable labs — Horizon Analytical and ILS Laboratories — 33 of 101 certificate records confirmable against the issuing lab under the Northline Labs client name, at ~99.5% reported purity.

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%.

A focused storefront with per-product certificates from ILS Laboratories and Vanguard Laboratory, including laboratory-confirmed reports and vendor-published documents with detailed testing panels.

A compact peptide catalog with ILS Laboratories and Vanguard Laboratory certificates reporting purity, identity, quantity, endotoxin, sterility, and heavy-metals results. 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.

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.

A USA-based storefront (TPC Research LLC) with public product pricing and a browsable Lab Reports archive of third-party Janoshik Analytical and Chromate Certificate-of-Analysis PDFs.

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.

A West Hollywood, California storefront built as a custom app rather than Shopify or WooCommerce, whose product bundle and public /coas page carry 35 recoverable Freedom Diagnostics COA PDFs — 33 of them resolving independently at the lab's own public lookup.

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.

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.

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.

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.

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.

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.

A U.S. research storefront in American Fork, Utah with openly listed vial prices and a public certificate-of-analysis library whose Freedom Diagnostics PDFs resolve at the laboratory’s public lookup under the NuLab Peptides / Nu Lab Peptides client name.

NuLab Peptides sells research-only singles and blends with prices on the product pages, including house codes GLP2-TZ / Tirz for tirzepatide and GLP3-RT for retatrutide, plus GLOW/KLOW, BPC/TB blends, and other research compounds. Its public /certificate-of-analysis/ library publishes downloadable Freedom Diagnostics certificates; PeptideBenchmark confirms printed Search Codes against Freedom’s public index when the client field names NuLab Peptides. Wholesale 10-vial multipacks stay outside the retail single-vial board.

A Northern Virginia–branded research storefront with openly listed vial prices on the public catalog and a large set of Freedom Diagnostics certificates that resolve on Freedom’s public index under the Blue Ridge Peptides client name.

Blue Ridge Peptides sells research-only singles and blends with prices on the product pages, including house codes BRP-1S / BRP-2T / BRP-3R for semaglutide, tirzepatide, and retatrutide, plus GLOW/KLOW and a Wolverine-style BPC/TB blend.

Step One Ventures sells research-only singles and blends with prices on the product pages, including house codes S-GLP1 / T-GLP2 / R-GLP3 for semaglutide, tirzepatide, and retatrutide, plus S-31-S for SS-31 and a GLOW blend. Freedom Diagnostics and ILS Laboratories PDFs on the public media library and product galleries name Step One Ventures (or S1 Research) as the client and resolve at the labs. Some storefront pages are age-gated; prices and certificates remain publicly checkable.

An Irving, Texas research storefront with openly listed vial prices and a public Freedom Diagnostics certificate trail that resolves under the AIO Peptides client name, plus named-lab MZBiolabs documents.

AIO Peptides sells research-only singles and blends with prices readable on the public catalog API, including house codes GLP1-S / GLP2-T / GLP3-R for semaglutide, tirzepatide, and retatrutide, plus GLOW / KLOW and common recovery blends. Freedom Diagnostics PDFs in the public media library name Client: AIO Peptides and resolve at Freedom via AIOP Search Codes; MZBiolabs watermarked reports appear as named-lab evidence without a public portal. HTML shop routes redirect to a login shell; prices and certificate files remain publicly checkable.

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.

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.

A Florida-made research storefront with openly listed vial prices and a dedicated Lab Reports index containing 40 laboratory documents: 39 with public laboratory verification and 1 available only from the vendor.

Distinct from Peptide Tech and Peptide Partners.

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.

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.

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.

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.

A Show Low, Arizona research storefront with public vial prices and a public certificate archive of Freedom Diagnostics images that can be checked at the laboratory under the Novaglo client name.

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.

A Zephyrhills, Florida research storefront with public single-vial and 10-vial prices and a public COA library of Freedom Diagnostics certificates that can be checked at the laboratory under Iron Aminos.

Iron Aminos sells each listed strength as a single vial or a 10-vial pack. RT-3, TRZ-2, and SMA-1 are the storefront names for retatrutide, tirzepatide, and semaglutide, mapped from the molecular weights published on those product pages. The public COA library keeps current and older Freedom Diagnostics certificates, including batches that are no longer the shipping lot.

A Costa Mesa research storefront with public vial prices and lot certificates from Vanguard Laboratory and Freedom Diagnostics that a reader can check at those laboratories.

Hello Stacks publishes standing prices for lyophilized vials and for StackOne prefilled pens and refill cartridges. 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.

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.

A Cypress, Texas storefront (Beastmode Labs LLC, doing business as Renova Peptides) with public single-vial and 10-vial prices and a public certificate page of vendor-hosted Vanguard Laboratory images.

Renova Peptides publishes a priced research catalog and a public certificates page. TRZ-2 and GLP TR are the storefront names for tirzepatide; RT-3 and GLP RT are the storefront names for retatrutide. The 10-vial products are separate pack prices. Vanguard Laboratory images on the certificates page print Renova Peptidos and are not in that laboratory’s public index, so they stay vendor-hosted documents. Kovera images on the same page resolve to Reta One Labs, a different Cypress storefront, and are not counted as Renova evidence.
