In the vendor's own words
Written by the vendor · Not verified by PeptideBase
Peptide Bros is a Canadian supplier of research peptides, with a catalogue presented for laboratory research use only and an age-verification gate in front of the site. The company states that its products are third-party tested and that certificates of analysis are available. It names no testing laboratory on the pages read. Those statements are the vendor’s own; PeptideBase has not verified them and holds no laboratory records for this supplier.
