A small Canadian supplier that shows its work.
Pure North Peptides supplies lyophilized peptide reference standards to researchers across Canada. We are owner-operated, we ship domestically, and we would rather tell you exactly what a certificate does and does not cover than round it up to a claim we cannot back.
Our official website is purenorthpeptides.com. Pure North Peptides is not affiliated with Pure Canada Peptides, True North Peptides, Northern Peptides, Great Northern Peptides, or the US company NorthPeptide (northpeptide.com).
Canadian-owned and operated.
A registered Canadian business run by its owners, not a marketplace listing or an overseas reshipper. The people who answer your email are the owners.
Ships from within Canada.
Every order is packed in Canada and handed to Canada Post Xpresspost within 24-48 hours of payment, tracked, in plain packaging. About four days to most addresses, no border, no customs.
Verified with the document in view.
Pure North commissioned Canada Peptide Testing, as a paying client, to test 13 named vial sizes by RP-HPLC-UV. Each public report is linked to its sample or lot/reference, report number, method, date, measured content, PDF, and laboratory-verification record. These results apply only to the samples tested and do not include mass-spectrometry identity or endotoxin results.
Paid the direct way.
Interac e-Transfer or Bitcoin, straight to us. No card processor sits in the middle, so no card details are entered anywhere on this site and there is no chargeback surface to price in.
Priced without games.
Retail is what the label says. No automatic tiers, no bundle markups, and stacks cost exactly the sum of their parts. Flat $30 CAD shipping; free over $300.
Here for the long run.
A physical retain of every lot is archived for five years from release. A question about a lot you bought last year can be answered from the same lot we shipped.
What we deliberately don't claim
Independent testing is part of our quality program: 13 vial sizes have published Canada Peptide Testing reports, reported 2026-09-12. They cover only the named vial sizes and lots or assigned references. For other peptide lots, a manufacturer QC certificate may be available on request; that document is not independent. Bacteriostatic water has no COA.
- Mass-spectrometry identity or endotoxin results for the current 13-report set. The published reports cover RP-HPLC-UV area purity and measured content only.
- Health Canada or FDA approval. These are laboratory research chemicals, not drugs, and they are sold for research use only.
- Medical guidance. Protocol pages reproduce published literature; nobody here will tell you what to do with a vial.
