Certificates of Analysis

Every batch is tested by an independent ISO/IEC 17025 accredited laboratory for identity, purity, and contaminants. Here are the certificates for the lots currently in stock.

Independent lab

Tested by ILS Laboratories, San Diego — ISO/IEC 17025 accredited.

Independently verifiable

Each certificate carries an access code you can check with the lab directly.

Research use only. A Certificate of Analysis reports the composition of the material tested. It is not a safety assessment and does not authorize human or veterinary use. Certificates relate only to the lot identified on them.
