Every Real Peptides product links its own Certificate of Analysis. Real Peptides' own certificate listing (realpeptides.co/coas, read 2026-09-27) tags the large majority of certificates to Kovera, with one product's certificate tagged to a second lab, Arrow Lab Solutions. Each report covers identity, purity (99.5–99.9% across the certificates reviewed), and net peptide content, alongside endotoxin testing under USP <85>. Those certificates are per-product rather than batch-matched — the lot field reads N/A. Real Peptides also states that its batches undergo heavy-metals and sterility testing. The listing's own meta description still names a third lab, Freedom Diagnostics, but no certificate on the current listing is tagged to it. Real Peptides accepts pay by bank, crypto and credit or debit card at checkout.
