What we found at Simple Peptide

Read 29 September 2026 on the vendor's own pages

The certificate side is real: a named lab, lot numbers, and a search code that the lab's own lookup confirms. The buyer side is not: no visible price, no measured net content on the reports we could open, no independent review record since Trustpilot removed the profile, and two 2025 Reddit warning threads we cannot test. A lab that will vouch for a March 2025 vial does not tell you what a September 2026 one costs or contains.

Checks out

✓A public certificate gallery of Freedom Diagnostics reports, viewable without an account. The Semaglutide 10mg report for lot P24102404 prints Accession 2503240009 and Search Code simp2503240009, purity 99.92%, reported 25 Mar 2025. source
✓We ran the search code on the lab's own lookup page on 29 Sep 2026 and it returned 'Document found' — the certificate exists at the lab, not only on the vendor's site. source
✓Legal entity and address printed in the terms: Melex Technologies LLC, 6586 W Atlantic Ave Ste #1112, Delray Beach, FL 33446, with a phone number (877-711-0702). A third-party public-record profile shows the same entity as the registered owner of the SIMPLE PEPTIDE trademark and no FDA warning letter matched.

?Measured net content — the certificates we could read print purity only, and the newest we opened is from March 2025; the on-site COA archive search returned an error on 29 Sep 2026.
?Any independent review record — the Trustpilot profile has been removed (29 Sep 2026).

This certificate does not state measured net content — purity alone does not tell you how much is in the vial, which is why the rubric scores them separately.

Lab lookup run 29 Sep 2026: 'Document found'. Purity only — no measured net content printed. Newest certificate we could open; the on-site archive search errored.

Score history and the caveats

A score only moves when the evidence does

2026-09-296/10 — first assessment (rubric v2); not awarded: net-content, ungated, review-base, sized-pricing — catalog and prices behind a free account; Trustpilot profile removed; lab search code confirmed at the lab

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.

Simple Peptide: the caveat

The catalog and every price sit behind a free account, so a buyer cannot see what a vial costs before registering; we do not create accounts, so no prices are recorded. Trustpilot profile REMOVED (read 29 Sep 2026). The certificates we could read print purity only, with no measured net content, and the newest we opened is from March 2025; the on-site COA archive search returned an error. Reddit carries two 2025 warning threads (under-filled vials, contaminated bacteriostatic water) that we cannot verify. A third-party record shows the Delray Beach suite is also the address of Alpha Omega Peptide.
