Short answer: legitimate, with caveats. As of 29 September 2026, Simple Peptide 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 (Freedom Diagnostics). 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 Simple Peptide ranks by compound are in the Simple Peptide review.

We found no evidence that Simple Peptide 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 (Freedom Diagnostics). Verify certificates yourself before ordering from any supplier.

Melex Technologies LLC · 6586 W Atlantic Ave Ste #1112, Delray Beach, FL 33446 · 877-711-0702 — terms page (29 Sep 2026); the suite number reads as a mailbox suite, disclosed as such (read 29 September 2026 from the vendor's own pages).
No on-site review badge; card payment accepted per a third-party checkout read; no FDA warning letter matched in a third-party screen on 29 Sep 2026 — Reddit complaints are noted on the review page but are not a regulator action. A card payment can be disputed with the issuer; crypto, Zelle and ACH cannot, which is why the rubric looks at the payment rail.
