We test what we ship. Each lot is analysed by a third-party laboratory and accompanied by a batch-specific Certificate of Analysis.
High-performance liquid chromatography confirms purity to ≥99%.
Molecular weight is validated to confirm compound identity.
A signed COA ships with every order and is available on request.
Lyophilized peptides are stable at −20 °C, protected from light. Once reconstituted with bacteriostatic water, store refrigerated and use within the documented window for your study design.
