Testing

Purity you can verify.

Every batch is assayed by lot and shipped with its certificate of analysis. Look up any lot below — no mystery vials, ever.

HPLC + mass-spec

Identity and purity confirmed by high-performance liquid chromatography and mass spectrometry for every lot.

COA in every box

Each order ships with its batch certificate; the same document is searchable here by lot number.

≥99% target

We publish the measured purity per lot and hold to a ≥99% target; out-of-spec lots are not shipped.
