Testing: Labs & Certificates of Analysis

Pure Peptides' compliance page lists 50 Kovera Labs certificates by batch, each with a report number and a link to verify it on Kovera's site, and the certificates read name PurePeptides as the client. Pure Peptides states that its laboratory is independent and accredited, and that batches below 99.0% purity by HPLC are rejected; the certificates print a purity specification of more than 98%.

Kovera's robots.txt closes its verification and certificate pages to automated readers, so Prof. Peptide did not look the certificates up at the laboratory.

Prof. Peptide hasn't checked these certificates against the labs' own records.

Pure Peptides is listed on Prof. Peptide's All Vendors page.

All products are sold for laboratory research use only and are not for human or veterinary use.

Payment and shipping

Pure Peptides ships within the United States only, by USPS with tracking, in cold-chain packaging. Orders placed before noon Eastern on a business day are dispatched that day, and shipping is free on orders over $150.

Customer service is through the contact form on its site; Pure Peptides states that it responds within one business day, Monday to Friday.
