What we found at ezPeps

Read 31 October 2026 on the vendor's own pages

One of the most open certificate records we have read: 186 certificates with lot IDs and status, links that resolve at the lab, and a named Michigan company with card checkout. What keeps it off ten: 'accredited' and 'cGMP' claims with no body behind them.

Contradiction — the vendor's claims disagree with each other or with the evidence

ContradictionThe homepage says every batch is tested 'at an accredited U.S

laboratory' and that every product is 'produced in cGMP-compliant labs'. Neither claim names an accrediting or certifying body, and the library spans five different labs (31 Oct 2026).

Score history and the caveats

A score only moves when the evidence does

31 Oct 20269/10 — first assessment (rubric v2): ILS Laboratories certificate served from the lab's file server (10.49mg on a 10mg label); 186-certificate lot library across five labs; EZ PEPS LLC, Michigan; card checkout; Trustpilot 4.8 / 249; not awarded: claims-consistent ('accredited U.S. laboratory' and 'cGMP-compliant labs' with no body named)

Purgo Labs: the caveat

Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.

ezPeps: the caveat

Not the same company as EZ Peptides (ezpeptides.com, EZ Peptides LLC, Albuquerque), which we also cover; codes and certificates do not carry across. The homepage says every batch is tested 'at an accredited U.S. laboratory' and every product is 'produced in cGMP-compliant labs', with no accrediting or certifying body named, so claims-consistent is withheld (the same call made on Rivn, Ameano, Idun and Prime Lab). The Trustpilot profile is claimed on a paid plan and invites reviews; 97% of reviews are five-star. A researcher confirmation overlay sits over the site but the catalog, prices and certificates load behind it. Refunds on unopened product within 30 days, as store credit or with up to a 15% restocking fee. Measured content 10.49 mg on a 10 mg label, one vial.

Is ezPeps legit?

ezPeps scores 9/10 on our rubric, has an independently viewable rating of 4.8 (249 reviews), and names its lab (ILS Laboratories (also Kovera Labs, Freedom Diagnostics, Horizon Analytical)). Caveat: Not the same company as EZ Peptides (ezpeptides.com, EZ Peptides LLC, Albuquerque), which we also cover; codes and certificates do not carry across. The homepage says every batch is tested 'at an accredited U.S. laboratory' and every product is 'produced in cGMP-compliant labs', with no accrediting or certifying body named, so claims-consistent is withheld (the same call made on Rivn, Ameano, Idun and Prime Lab). The Trustpilot profile is claimed on a paid plan and invites reviews; 97% of reviews are five-star. A researcher confirmation overlay sits over the site but the catalog, prices and certificates load behind it. Refunds on unopened product within 30 days, as store credit or with up to a 15% restocking fee. Measured content 10.49 mg on a 10 mg label, one vial.
