Disclosure: Purgo Labs is our affiliate partner, and so is Puratek Peptides (referral link only, no code). Scores come from the public rubric, which has no partnership input.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.

What we found at Puratek Peptides
Read 5 September 2026 on the vendor's own pages
The cheapest BPC-157 in this batch from a company that names its lab and its LLC — and whose independent review record has been removed by Trustpilot, whose purity guarantee changes number from page to page. Price is not the only thing being compared.

?Trustpilot profile is REMOVED ('goes against our guidelines', read 5 Sep 2026). No independent review base exists for this vendor.
?Certificates are vendor-hosted images with no lab-side verification link; the certificate we checked carries no lab name in its caption.
?TB-500 is listed at a single price with no size stated; GLP products (PUR-1S / PUR-2T / PUR-3R) show price ranges without sizes, and the vendor does not state the compound identity.
!Purity guarantee is stated as 99% on the homepage, 98.5% on the dedicated policy page, and both figures appear within the same About-Us FAQ.
!A footer link on every page points to an unrelated test domain instead of the vendor's own site.
!Removed Trustpilot profile; on-site trust language continues unchanged.

Where Puratek Peptides ranks by compound
Puratek Peptides appears in 12 of our compound rankings, top-3 in 1. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-067/10 — re-issued under rubric v2 (was 3/8); not awarded: review-base, claims-consistent, sized-pricing
2026-09-167/10 — became an affiliate partner (10% commission, referral link; no customer code confirmed yet). Score unchanged — partnership is not a rubric input; all 5–6 Sep findings, including the removed Trustpilot profile, stand as published
Purgo Labs: the caveat
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
Puratek Peptides: the caveat
Trustpilot profile removed for guideline violations (read 5 Sep 2026) — no independent review base. The certificate we opened is an ILS Laboratories report (COA-2026-413074, lot BPC10005, 10.7mg vs 10mg) with an ILS access code — while the certifications page credits Freedom Diagnostics. Purity guarantee is 99% on the homepage and 98.5% on the policy page. TB-500 and GLP products are listed without stated sizes, and the GLP compound identities are not stated.
