Testing: Labs & Certificates of Analysis
NextSelf Labs links its certificates of analysis from each product page, with no account needed: 59 when Prof. Peptide read them on November 5, 2026, all naming NextSelf as the client. Thirty-two are from Freedom Diagnostics (samples received June to August 2026) and list identity by LC-MS, HPLC purity and net content, each with a Search Code for Freedom's lookup. Twenty-seven are from ILS Laboratories (analysed September to October 2026) and list HPLC purity, net content, identity by HPLC retention time and a fentanyl screen, each with an access code and a verify link. Prof. Peptide has not yet checked any of them at the laboratory, so NextSelf Labs carries no Verified badge.
