Each batch is analyzed by high-performance liquid chromatography (HPLC) and confirmed by mass spectrometry. Independent third-party laboratories verify the results, which are published as a Certificate of Analysis (COA) tied to the production lot.

Lyophilized peptides should be stored at -20 °C and protected from light. After reconstitution, store at 2–8 °C and use within the recommended period. Avoid repeated freeze–thaw cycles to preserve integrity.

Our standard analytical panel includes HPLC for purity quantification and mass spectrometry (MS) for identity confirmation. Additional tests may be performed depending on the product. Methods are listed on each Certificate of Analysis.
