Analytical Approach to Finished Formulations: Purity is a metric used for isolated raw materials, such as lyophilized peptide powders. Finished formulations—such as capsules, liquids, and topicals—contain multiple components, including excipients and stabilizers. In these systems, a single purity value does not accurately represent the overall composition. Instead, identity and assay (content) are reported on the COA to confirm the presence of the correct compound and to verify that the labeled amount per unit is accurate. This approach reflects standard analytical practice and provides more meaningful information for research applications
