The supplier confirms the final price and availability when you order. Product names, photos, quantities and prices are as publicly listed by the supplier; photos load from the supplier’s own website. “vs market” compares price per mg with the median across tracked suppliers listing the same peptide in the same currency; prices are never converted between currencies. We do not sell these products and give no guidance on their use.

Northwest Peptides: testing and transparency
Northwest Peptides is a United States-based research-peptide supplier listing 22 of the peptides we track, priced in USD. Where it does well: states independent testing and names Freedom Diagnostics; links a certificates-of-analysis page (not yet reviewed by us). Where it falls short: we found no company name or registration number on its website. Our Transparency Score is 4.6/10, provisional until more of our criteria have been assessed.
