Every batch, documented.
Every dōse·one compound is tested and documented with a lot-specific Certificate of Analysis. No exceptions, no faith required. Here's what that means and how to access it.
What a CoA is
A Certificate of Analysis (CoA) is an independent lab report verifying exactly what's in a vial. Every batch we sell is tested by accredited third-party laboratories before it's released. The CoA documents purity, identity, and a full quality-control panel, traceable to the specific lot.
What we test for














If a lot doesn't pass, it doesn't ship.
