Short answer: legitimate, with caveats. As of 5 September 2026, Optima Supply scores 6/10 on our published verification rubric, has no independently viewable review record (its Trustpilot profile has been removed), and names its testing laboratory (Janoshik Analytical · Chromate Labs · ILS-Lab). There are real verification gaps, listed below, that a careful buyer should weigh before ordering.
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.
One point per criterion, no weighting, same rubric for every vendor. The dated evidence behind each point is in the full review.
This page answers the trust question. Prices with the code, the certificate we opened (lot, purity, measured mass), and where Optima Supply ranks by compound are in the Optima Supply review.
Affiliate partner; we earn a commission on Purgo orders. We earn nothing from Optima Supply. Scores are computed from published evidence and do not read partner status.
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.
Our vendor-vetting checklist and COA reading guide walk through each step for any vendor.

We found no evidence that Optima Supply is a scam. What we can say is limited to what is independently verifiable: 6 of 10 verification criteria earned, no independently viewable rating, and a named testing lab (Janoshik Analytical · Chromate Labs · ILS-Lab). Verify certificates yourself before ordering from any supplier.
Certificates are available — Some reports resolve on chromate.org/verify and janoshik.com/tests (others are vendor-hosted PDFs). We did not confirm batch-matched lots on every product.
