Lab results and Certificates of Analysis
Every batch is tested by an independent third-party laboratory, and the result is published here as a Certificate of Analysis (COA). Each certificate reports the HPLC purity where a purity assay was run, the net peptide content per vial and, where the batch was tested for it, bacterial endotoxin. Blends report the measured content of each component instead of a single purity figure.
To match a vial to its certificate, find the batch code on the vial and look for it on the cards below, where each card shows the lot / batch number and the sample code under the compound name. Open that card for the full certificate: test method, specification, result and analysis date. Certificates are listed newest first, and the full lab report for any batch is available on request. Research use only.
