Controlled supply chain
Cagrilintide Labs works with qualified manufacturing partners and maintains defined specifications and quality requirements for Cagrilintide research material. Cagrilintide Labs is not the physical manufacturer; its role is to control what is sourced, document each batch, have it tested independently and publish the results.
Defined specifications
Cagrilintide Labs’ stated release specification is ≥95% HPLC-UV purity with identity confirmed by LC-MS against the expected molecular weight of 4409.07 g/mol. The full specification, from molecular formula to physical form, is published on the Cagrilintide specifications page.
Independent analytical testing
Testing is performed by Freedom Diagnostics, an independent laboratory, not in-house. Instead of a "third-party tested" badge, each lot's actual results are published: current lots report 99.91% purity, with identity confirmed on every lot. How each test works.
Lot-level transparency
Any vial can be traced in one path: product, lot number, testing, certificate and verification. Start with the lot number on the label at cagrilintide.bio/verify.

Released lots are available through Klow.bio, the purchasing platform operated by Klow Labs, which also operates Cagrilintide Labs.
