All Vendors
A directory of the peptide vendors we profile. Each vendor's profile names the laboratory that tested it, from the vendor's own published certificates.
Lab & COAs Verified means Prof. Peptide read the vendor's certificates of analysis and matched them against the testing laboratory's own records, using the laboratory's lookup after confirming that it rejects a made-up certificate code. Vendors without the badge have not had their certificates matched at the laboratory.
