About North Peptide

North Peptide is a US-based peptide supplier founded with a simple mission: to provide researchers with the highest-quality peptides backed by full transparency and rigorous documentation.

Our Standards

We send select lots to independent third-party laboratories to verify identity, purity, and composition, and we publish those certificates of analysis on our test results page. COA coverage varies by product and lot.

• Purity, content, and identity reported by the laboratory, published exactly as each certificate states them — including identity confirmation by LC-MS on the certificates that carry it
• Batch documentation available for tested lots
• Temperature-controlled shipping to maintain peptide stability
• Secure packaging with discrete, tracked delivery

Who We Serve

Our customers include university research labs, independent scientists, biotechnology companies, and clinical research organizations. Whether you need a single vial for a pilot study or bulk quantities for a larger project, we provide consistent quality and reliable service.

All products sold by North Peptide are intended exclusively for laboratory and research purposes. They are not approved for human or veterinary use, and we do not sell to individuals intending to use our products outside of a legitimate research context.
