LabSourced Peptides Review: Pricing, COAs, Testing, and What We Found
An independent LabSourced Peptides review covering its priced research catalog, Peptide-R and Peptide-T house labels, BOGO terms, and provider-verified ILS and Vanguard certificates.
LabSourced Peptides is now a curated vendor on PeptideBenchmark. The decision is based on evidence researchers can inspect: a broad priced catalog, product-linked certificate documents, and report identifiers that resolve independently at the issuing laboratories.
The main finding is the certificate trail. Published reports can be checked at the issuing laboratories. During the September 30, 2026 review, we could not retrieve some older vendor PDFs. PeptideBenchmark distinguishes preserved vendor copies, current laboratory confirmations and unresolved document relationships. Current coverage and verification appear on the live LabSourced profile.
Reviewed August 18, 2026, with no affiliate, coupon, sponsorship, or paid-placement relationship at that time. Update, September 11, 2026: PeptideBenchmark now has a disclosed affiliate relationship with LabSourced (code BENCHMARK, a standing 15% off, tracked via ?ref=benchmark) and may earn a commission on referred orders. The original August findings were reached before that relationship existed; later certificate-access and publication updates are identified below. Affiliate status never affects scoring, ranking, or testing conclusions. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
Certificate-access and publication notes were updated on September 30, 2026. The figures below preserve the August 18, 2026 review snapshot. The live profile carries the current evidence summary.
The short version
At the original August 18 review, we found:
- a 75-product research catalog with 53 in-stock, mg-normalized vial rows published to Pricing and Stack Builder;
- no unresolved pricing deferrals;
- 19 rows outside the vial comparison at review time, plus three sold-out vial rows retained in the coverage audit; the September 18, 2026 IU snapshot carries the qualifying hCG offer;
- 61 reviewed certificate relationships after duplicate reconciliation, 58 independently confirmed at ILS Laboratories or Vanguard Laboratory;
- Peptide-R and Peptide-T house labels mapped to retatrutide and tirzepatide;
- a buy-one-get-one promotion observed on August 18, 2026, excluding merchandise.
Researchers can inspect published reports and their laboratory checks. A named-sample certificate does not establish the condition of every shipped vial. Read the document identity and access caveats, recognize the Peptide-R/T house labels, and re-check current promotion terms.
What we found in the catalog
LabSourced lists research singles and blends across a wide range of vial strengths. In the Vials tab, PeptideBenchmark publishes only rows that are in stock, have a clean compound identity, and can be normalized by milligrams.
| Catalog result | Count | PB treatment |
|---|---|---|
| Catalog products | 75 | Retained in the coverage audit |
| Comparable vial rows | 53 | Published to Pricing and Stack Builder |
| Deferred | 0 | — |
| Outside the vial lane at review time | 19 | Support liquids, HCG labeled in IU, and merchandise |
| Out of stock | 3 | Retained for coverage history, not current pricing |
The September 18, 2026 unified-pricing snapshot lists 1 LabSourced hCG offer in IU hormones. Support liquids and merchandise remain outside Pricing.
Important house labels include:
- Peptide-R → retatrutide
- Peptide-T → tirzepatide
- Wolverine → BPC-157 / TB-500 blend
- MTP-31 → SS-31
The storefront’s buy-one-get-one offer was active during the August 18 review and excluded merchandise SKUs. PeptideBenchmark models it as a freshness-limited observed promotion, not a permanent promise. Check the live cart before relying on the offer.
Current rows can be compared on PeptideBenchmark Pricing, and multi-product requirements can be modeled in the Stack Builder.
The certificate evidence
Browse preserved records in the LabSourced COA results.
At the August 18 review, the archive contained 61 certificate relationships tied to 59 product identities after one duplicate legacy Cagrilintide registry row was collapsed:
- 17 ILS Laboratories records, all provider-confirmed;
- 44 Vanguard Laboratory documents, 41 provider-confirmed.
That original review confirmed 58 relationships through the issuing laboratory and identified unresolved compound or strength mismatches in PE-22-28 and Wolverine document relationships. Those unresolved relationships remain in the evidence review without provider-verification badges. Among documents extracted for that review, average reported purity was about 98.82%. Reported test panels varied by laboratory and document.
The current published index also includes a Chromate certificate for benzyl alcohol solution that names eBac Water as the customer. LabSourced publishes the certificate; confirmation of the report does not establish a LabSourced laboratory-client relationship. Laboratory identity, vendor publication and product matching are separate facts.
That evidence supports a specific claim: the named report exists at the issuing laboratory and describes the named sample. It does not prove that every unit sold matches that sample, establish safe handling or use, or turn a certificate into a blanket endorsement of the vendor.
Access, identity, and location
The original storefront review encountered a researcher-access confirmation before the shop and COA views. We retrieved current published files during the September 30, 2026 review, but could not retrieve some older vendor PDFs. Preserved vendor copies retain their historical context; a current laboratory lookup confirms that report without making an older vendor copy a newly obtained document.
The footer lists WWBservices, 30 N Gould St, Sheridan, Wyoming. PeptideBenchmark records that as a vendor-stated postal/business-contact address, not as proof of a laboratory, warehouse, or fulfillment facility. The labsourced.com domain is young, dating to around October 2025, so its operating history is shorter than many established vendors in the comparison set.
What this review does not claim
- It does not claim LabSourced products are safe, effective, or appropriate for any use.
- It does not treat a laboratory-confirmed report as proof that a later shipped vial matches the tested sample, or that the named laboratory customer is LabSourced.
- It does not treat the Wyoming postal address as a verified laboratory or fulfillment site.
- It does not promise that the observed BOGO promotion will remain active or keep the same eligibility terms.

Common questions
Is LabSourced Peptides legitimate?
PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. We confirmed a priced research catalog, a Sheridan, Wyoming postal address published through WWBservices, and a published certificate archive with records independently confirmed at the issuing laboratories. Those facts create an inspectable evidence trail; they do not establish the condition or safety of a physical vial.
Does LabSourced publish COAs?
Yes. LabSourced publishes product-linked certificates. During the September 30, 2026 review, we could not retrieve some older vendor PDFs; preserved copies and laboratory-hosted reports remain inspectable. The live vendor profile shows current coverage and verification; unresolved document relationships do not receive provider-verification badges.
What do Peptide-R and Peptide-T mean?
They are LabSourced house labels. The catalog and matching certificate evidence identify Peptide-R as retatrutide and Peptide-T as tirzepatide.
Does LabSourced offer buy one get one free?
A buy-one-get-one offer was active when PeptideBenchmark reviewed the catalog on August 18, 2026, with merchandise excluded. Promotions can change, so confirm the current cart terms before relying on it.
Does PeptideBenchmark have an affiliate relationship with LabSourced?
Yes, as of September 11, 2026. At the time of this review (August 18, 2026) there was none. PeptideBenchmark now has a disclosed affiliate relationship: the code BENCHMARK is a standing 15% off, tracked through the ?ref=benchmark referral link, and PeptideBenchmark may earn a commission on referred orders. The relationship came after the evidence findings below and did not change them, the trust score, or where LabSourced ranks.
