Peptidology launched the Certificate Library, which brings current, earlier, and discontinued lot records into a single searchable location for researchers to review documentation beyond the available lot.

Peptidology provides custom synthesized and catalog analytical standards, reagents and supplies for lab, testing and research use — with peptide chemistry at the core. Catalog or custom, every lot we release is backed by a 14-point analytical program (purity, net peptide content, endotoxins, heavy metals, residual solvents and TFA, container-closure integrity, and sterility verified by two independent labs), tested under ISO/IEC 17025:2017 accreditation, with a lot-specific Certificate of Analysis on every order. A responsive U.S.-based team, cGMP-aligned manufacturing, and same-day shipping (by 3 PM MT, Mon–Fri). Trusted by 29,000+ researchers, headquartered in Scottsdale, AZ. For Research Use Only. Not for human or veterinary use.
