About PeptideProof

The research-peptide market has a trust problem: purity claims are unreliable, COAs are self-reported, and "best vendor" lists are usually paid placements in disguise. Counterfeit products have tested as low as a fraction of their claimed purity.

PeptideProof fixes one thing well — we independently buy and lab-test vendors, and publish the receipts. Good or bad, the number is the number.
