Testing: Labs & Certificates of Analysis
Endura publishes 28 certificates of analysis on its own site, with no account needed. Fifteen are from Freedom Diagnostics (received May 27, 2026) and list purity, identity and net content, with endotoxin on nine. Thirteen are from ILS Laboratories (analysed November 3, 2026) and list purity, net content, identity, a fentanyl screen, heavy metals, sterility and endotoxin. Each names Endura as the client and carries a lookup key for the laboratory.
Mark of Prof. Peptide looked up three of the ILS certificates on ILS Laboratories' own verify page on November 7, 2026, and each was tested for Endura Peptides and matched Endura's copy: BPC-157 10 mg (COA-2026-JB23DR), GLP-3R 20 mg (COA-2026-4LOJSV, identity confirmed as retatrutide) and GLP-1S 10 mg (COA-2026-H5RES4, identity confirmed as semaglutide). Those three certificates' results are below.
