About
A supplier, not a marketer
PNW Peptides (Pacific Northwest Peptides) operates from Hayden, Idaho, founded by analytical chemists who spent years sourcing reference materials with incomplete paperwork. We built the company we wanted to buy from: a narrow catalogue of research peptide vials, verified specifications, and no claims beyond what the data supports.
We supply laboratories, universities, and contract research organisations. We do not advise on applications, and we make no representations about biological effects. Our role is to deliver well-characterised material with the documentation to prove it.
