About Durham Peptides

Durham Peptides (durhampeptides.ca) is a Canadian research peptide retailer marketing itself as "Canada's trusted peptide supplier" with featured offerings including BPC-157, GHK-Cu, Tirzepatide, and Retatrutide. The site claims Janoshik Analytical lab testing, same-day shipping, and free shipping on orders over $200 CAD. Pricing is in Canadian dollars and products are framed for research use only. Currently flagged as draft because the durhampeptides.ca domain was registered on March 23, 2026, making it under 2 months old at time of writing. The WHOIS registrant uses Namecheap privacy protection, and the vendor has no independent community track record on Reddit or established Canadian peptide forums (e.g., Canadian Brawn) that we could verify. Trustpilot shows a presence but with insufficient review volume to corroborate quality claims. The Janoshik testing claim is a strong positive signal but requires direct buyer verification of batch-specific reports.

Durham Peptides claims Janoshik Analytical lab testing on every batch but COA accessibility from the public catalog could not be confirmed at time of review. Buyers should request batch-specific Janoshik reports before purchase to validate the claim. 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.

Linked names have a record here; the others we hold nothing on yet. A vendor listing a compound says nothing about the evidence for it.
