Verification
Certificate of Analysis
Certificates are published on each product page against the lot number on your vial.
Independent verification
Every batch we release is assayed by an independent laboratory before it ships. Certificates are published per lot and stay available after the lot sells out, so a purchase made months ago can still be checked against the document that covered it.
How to read a certificate
Each certificate names the compound, the lot it covers, the laboratory that ran the assay and the date it was run. Purity is measured by HPLC and reported as a percentage of total peptide content. Match the lot number on your vial label to the batch on the certificate.
Certificates are published as they are returned by the laboratory. A product without a published certificate is not listed on this page.
All products are sold strictly as chemical reference standards for in-vitro laboratory research. Not for human or veterinary use.
