American Peptides
americanpeptides.usPublishes lot-referenced certificates from a named laboratory, with the lot numbers repeated on the product pages. The documents are shown in full and include both an HPLC chromatogram and a mass spectrum, so identity as well as purity is addressed. One certificate carries an endotoxin result under USP<85> — the only endotoxin figure found anywhere in this catalogue — but no sterility report was found despite a site-wide "Sterility Verified" banner. A city is published but no street address, suite or registered legal entity, and no laboratory accreditation number is cited.
