Testing: Labs & Certificates of Analysis
Certified-Pep publishes a COA library listing a certificate and a separate contaminant report for each product, all from Vanguard Laboratory of Olympia, Washington. The certificates print “Report To: Certified Peptides”, so the vendor is the laboratory's client, and Vanguard's own lookup files 113 certificates under it.
Two were checked at Vanguard's own lookup on October 17, 2026, and both matched: SS-31 10 mg, chromatographic purity 98.78%, and BPC-157 10 mg, purity above 99.80%, with 11.61 mg measured in a vial labelled 10 mg. The certificates' footers cite “A2LA Certificate #6377.01.01” for the list of accredited tests. That number returns no records in A2LA’s directory, which lists Vanguard Laboratory under certificate 6377.01, with a biological scope.
All products are sold for laboratory research use only.
