About Northern Peptides
Northern Peptides is a Canadian retail peptide vendor operating at northernpeptides.is. The .is offshore top-level domain is common among grey-market vendors and does not by itself indicate legitimacy or illegitimacy. This vendor is distinct from the separately profiled Great Northern Peptides; the two share naming conventions but appear to be different entities. Trust signals, third-party COA policies, ownership, and shipping specifics have not been independently verified by Peptide Protocol Wiki. Users should independently confirm product testing, refund terms, and payment logistics before purchase.

COA policy not independently verified. observed
A COA describes one batch's purity. It is a document about a vial, not evidence about an effect, and it never grades a claim on this site — the grading rubric names what qualifies.
