Quality

Completely open about
our testing. Always.

No purity claims you can’t check yourself. Every lot is independently tested, and its full Certificate of Analysis is published on this site — that’s the whole point of the name.

— 01

Independent HPLC analysis

Each lot goes to an unaffiliated U.S. analytical laboratory for identity, purity, and net-content testing before it reaches our shelf. We never self-grade.

— 02

The COA goes public

The full certificate — the actual lab report, not a summary badge — is published on our Certificates page for every lot we sell. Match your vial’s lot number and read the record.

— 03

99% purity, guaranteed

If a vial ever fails to match its published COA, we replace it or refund it. No store-credit games, no fine print.

Every lot. Every certificate. Public.
