AmericanPeptide sells nothing. It reads what each vendor actually publishes and ranks them by one thing: the provenance tier of the purity claim. An independent, per-batch COA backs a third-party claim; a vendor’s own number backs a vendor-reported one. Same scale as the chemistry, the monographs, and everything else here — the Standard.
