We'd prefer to. Unfortunately, Visa, Mastercard, American Express and PayPal all maintain lists of restricted industries they won't process — and research peptides are classified under "research chemicals," which sits on that list. This applies to every peptide supplier in Canada and the US, not just Durham Peptides.

​

That makes Interac e-Transfer the practical alternative, and it's a good one: bank-to-bank, instant, and no card details are ever stored or transmitted. Payments confirm automatically through autodeposit — no security question required — so your order is received the moment you send.

​

Once payment lands, your Canada Post Xpresspost tracking number follows by email, usually within hours. Orders paid before 5:00 PM ET (Monday–Friday) ship the same business day.

​

A note on email: some providers (Hotmail, Outlook, Yahoo) occasionally filter shipping notifications to spam. If you don't see your tracking, check your junk folder first, then email us and we'll resend right away.
