Independently Verified

Third-Party Lab Tested — See the Proof

Every batch is independently lab-tested before it goes on sale, and we publish the full Certificate of Analysis so you can confirm identity, content and purity before you buy. Our newest lots are analyzed by Freedom Diagnostics Testing — an American-owned and operated laboratory — covering identity, purity and elemental impurities (heavy metals). Earlier reports below were issued by Janoshik Analytical. Every report carries its own QR code and verification code, so you can confirm with the issuing lab that it is authentic and unaltered.
