How we test
Product quality is our number one priority.
We work with independent laboratories including Janoshik, Freedom Diagnostics and Kovera Labs. The lab, not Cenvia, runs the analysis and issues the certificate.
A certificate of analysis is on file for every product. When a certificate is published to a product page, it appears as a result card with the lab, the lot that was tested, the test date and the measured values. Earlier lots stay available in the card history.
