Prometheus Peptides is a Canadian peptide supplier dedicated to providing researchers, biohackers, and health-conscious individuals with the highest-quality, independently verified peptides available on the market. We believe that transparency and scientific rigor should be the foundation of every product we offer.
Every batch of peptides we carry is independently tested by third-party laboratories — including internationally recognized facilities such as Janoshik — before it ever reaches our customers. We publish Certificates of Analysis (COAs) for every product so you can verify purity, average mass, and batch identity yourself. No guesswork, no blind trust.
Our catalog spans a wide range of research compounds including GLP-1 receptor agonists like Retatrutide, tissue-repair peptides like BPC-157 and TB-500, nootropics such as Semax and Selank, anti-aging compounds like GHK-Cu and NAD+, growth hormone secretagogues, and more. We continuously expand our catalog based on the latest peer-reviewed research and customer demand.
We are based in Canada and ship domestically with fast, discreet, and reliable service. Orders over $150 CAD ship free. We are committed to customer satisfaction and stand behind every product we sell.
Prometheus Peptides was founded with a single mission: make the best peptides accessible to Canadians without compromise on quality or transparency. We are a small, passionate team of researchers and health enthusiasts who hold ourselves to the highest standards — because we use these products too.
All products are intended for research purposes only and should not be used without the direction of a licensed physician.
