Research peptides, documented like it matters.
Every Pepmolecule batch is third-party tested for identity, purity, and endotoxins — and the certificate of analysis is published here, searchable by lot number, before you spend a dollar. No COA ‘available upon request.’ No mystery lots.
How a batch earns its listing
- Independent US lab tests every batch for HPLC purity, mass-spec identity, and endotoxins.
- The full certificate is published in our COA registry before the lot goes on sale.
- The lot number on your vial matches the certificate and your order — always.
