Disclosure: Purgo Labs is our affiliate partner; we earn nothing from Optima Supply. 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 Optima Supply
Read 5 September 2026 on the vendor's own pages
Genuinely strong testing documentation — multiple named labs, measured mass on the certificates — sitting next to a removed Trustpilot profile and a price that differs by $30 depending on which page you read. Verify the price at checkout and read the certificate for your lot.

?Trustpilot profile is REMOVED ('goes against our guidelines', read 5 Sep 2026). Third-party directories still show a 4.7/233 figure — that number no longer exists anywhere a reader can check.
?Lot-to-vial matching relies on a vendor-stated QR system; certificate PDFs do not print a lot number we could read.
?Many basket-item reports are vendor-hosted PDFs rather than lab-hosted.

Where Optima Supply ranks by compound
Optima Supply appears in 5 of our compound rankings. Each ranking orders every scored vendor that sells the compound by rubric score, then verified price per mg.
2026-09-066/10 — re-issued under rubric v2 (was 5/8); not awarded: per-lot, review-base, claims-consistent, clean-record
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.
Optima Supply: the caveat
Trustpilot profile removed for guideline violations (read 5 Sep 2026) — no independent review base exists, and the site still displays a review badge without disclosing the removal. BPC-157 10mg is $85 on its product page and $55 on the homepage. Lot-to-vial matching relies on a vendor-stated QR system we could not verify; many basket reports are vendor-hosted PDFs.

Where the evidence points
Where the evidence points
Purgo Labs 10/10
We earn nothing from Optima Supply. Purgo Labs holds every rubric point — certificates checkable at the lab, measured net content per lot — and is cheaper after codes on 5 of 5 like-for-like vials.
Purgo Labs, on the evidence: 10/10 rubric points against 6/10. Optima Supply is stronger on 3 points listed below. Every point is a fact you can check on either vendor's site; both are scored by the same published rubric.
Is Optima Supply legit?
Optima Supply scores 6/10 on our rubric, has no independent record (its Trustpilot profile has been removed), and names its lab (Janoshik Analytical · Chromate Labs · ILS-Lab). Caveat: Trustpilot profile removed for guideline violations (read 5 Sep 2026) — no independent review base exists, and the site still displays a review badge without disclosing the removal. BPC-157 10mg is $85 on its product page and $55 on the homepage. Lot-to-vial matching relies on a vendor-stated QR system we could not verify; many basket reports are vendor-hosted PDFs.
Which is cheaper, Purgo Labs or Optima Supply?
On the 5 compound-and-size rows where we have dated prices from both, Optima Supply lists lower on 1 and Purgo Labs on 4. Purgo's list prices drop 20% with code HEALTH.
Do you earn money from either vendor?
