Disclosure: Purgo Labs is our affiliate partner, and so is TrustedPeps. 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.

Only vials both vendors list at the same size, read on each vendor's product page on the date shown. "After code" is list × the code's stated discount — a calculation, labelled as one; stacking with sale pricing is not cart-tested.

What we found at TrustedPeps
Read 5 September 2026 on the vendor's own pages
Cheap, well-reviewed, and almost entirely unverifiable: no lab, no entity, no address, and weight-loss compounds sold under codes the vendor never decodes. The rubric score reflects what is published; the caveats reflect what is not.

Could not verify · flags
?No laboratory is named anywhere on the site despite repeated 'independent third-party lab tested' claims. Certificates are vendor-hosted images.
?No legal entity and no address on About, Contact, or Terms — the site says only 'Location: United States'.
?GLP-class products are sold as 'TP-TZ' and 'TP-RT' with no statement anywhere of what compound is in the vial. Their prices are listed below but excluded from our price index.
?No standalone TB-500 — only a 5mg/5mg blend with BPC-157.
!Domain under a year old, private-mailbox registrant, no entity disclosed. Combined with an unnamed lab, the vendor's purity and identity claims cannot be checked from outside the site.
No legal entity or address disclosed on the vendor's site.
TrustedPeps appears in 8 of our compound rankings, top-3 in 3. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-069/10 — re-issued under rubric v2 (was 5/8); not awarded: 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.
TrustedPeps: the caveat
The lab (Freedom Diagnostics) appears only on the certificate image, never in page text; the certificate carries a lab search code (Trus2604010178) and reports 10.50mg vs 10mg label. No legal entity and no address on About, Contact or Terms — 'Location: United States' only. Weight-loss compounds sold as 'TP-TZ' and 'TP-RT' with the identity never stated; those prices are excluded from our index. Domain under a year old.
