Disclosure: Purgo Labs is our affiliate partner; we earn nothing from PeakForce Labs. 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 PeakForce Labs
Read 5 September 2026 on the vendor's own pages
Public certificates and a big review base, undercut by two things: nobody can confirm which lab produced the certificates, and the review base is incentivized by the vendor's own points program.

Could not verify · flags
?The testing laboratory is never named; the site says only 'accredited third-party laboratories' and 'LC-MS/MS'. Certificates are vendor-hosted images.
?Lot/batch matching and measured net content — certificate images not readable from outside.
?No legal entity (LLC/Inc.) disclosed anywhere on the site — trade name only.
?No standalone TB-500; it is sold only inside the 'Wolverine' blend.
!Homepage and contact FAQ say US-only shipping; the dedicated FAQ page says the vendor ships to a few other countries.
!The homepage rewards section offers +1,000 points for leaving a review on Trustpilot — the same Trustpilot score used as independent validation. Treat the review count with that in mind.

Where PeakForce Labs ranks by compound
PeakForce Labs appears in 4 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-068/10 — re-issued under rubric v2 (was 3/8); not awarded: claims-consistent, identity
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.
PeakForce Labs: the caveat
The homepage rewards program offers points for leaving a Trustpilot review, so the review base is vendor-incentivized. The lab (Freedom Diagnostics) appears only on the certificate, never in page text; the certificate carries a lab search code (Peak2604060063) and reports 11.12mg vs 10mg label. No legal entity disclosed — trade name only. Retatrutide is sold as 'PFL-RT' with the compound never named. Shipping policy contradicts itself between pages.
