Durham Peptides is a Canadian-owned and operated research peptide supplier based in Durham Region, Ontario. We supply researchers across Canada with high-purity, independently tested peptide compounds for laboratory and scientific applications.

 

We were founded on three principles: uncompromising quality, complete transparency, and fast reliable service.

​

Our Testing Standards

​

Every product we sell is verified through independent third-party analytical testing by Janoshik Analytical, one of the most respected peptide testing laboratories in the world. Each batch undergoes HPLC (High-Performance Liquid Chromatography) purity analysis to confirm purity exceeding 99%, and mass spectrometry to verify compound identity and molecular weight. We believe third-party verification is non-negotiable — it is the only way to ensure that what is on the label matches what is in the vial. Certificates of Analysis are available for every product upon request, and researchers can independently verify results directly through Janoshik's verification portal. View our Lab Results page for more information.

 

Our Sourcing

 

We source exclusively from established manufacturers operating in cGMP-compliant (current Good Manufacturing Practice) facilities with documented quality control processes. Every Certificate of Analysis is independently verified before any product is listed for sale. We do not resell from middlemen or unverified distributors — we maintain a direct relationship with our manufacturing partner and verify every batch at the source.

 

100% Vegan & Cruelty-Free

 

All Durham Peptides products are 100% synthetically manufactured through chemical laboratory synthesis. They contain no animal-derived ingredients, no porcine components, no bovine derivatives, and no gelatin. No animal testing is involved at any stage of production. This distinction matters in the peptide industry — historically, many peptide compounds (including early formulations of BPC-157) were derived from porcine or bovine tissue. Our fully synthetic manufacturing process ensures consistency, eliminates contamination risk from biological sources, and makes every product compatible with vegan and cruelty-free principles.

 

Serving the Canadian Research Community

 

Every order ships domestically from within Canada via Canada Post Xpresspost, with most deliveries arriving in 1–3 business days. Domestic shipping means zero customs intervention, no import duties, no cross-border seizure risk, and no multi-week delays. Orders confirmed before 2:00 PM EST ship the same business day with full tracking provided. We built Durham Peptides specifically to serve Canadian researchers who were tired of unreliable international shipping and inconsistent product quality.
