Testing: Labs & Certificates of Analysis

NextGen Peptides publishes a certificate library of 178 certificates, listed by product, lot, purity and date, with earlier lots kept beside the latest. Every certificate is a report from ILS Laboratories of San Diego, issued to NextGen Peptides and printed with an access code.

All 178 access codes were checked at ILS's own lookup on 9 October 2026, after it refused an invented code, and each returned the same certificate number the PDF prints. The ILS reports cover purity by HPLC, net peptide content, identity by HPLC retention-time match, sterility, endotoxin and heavy metals, and most add a fentanyl screen.

All products are sold for laboratory research use only.
