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 Sou100% 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.
