A certificate of analysis (COA) is an independent laboratory report issued for a specific production batch. The lab receives a sample, runs analytical testing on it, and documents exactly what the sample contains. It is the proof behind a label claim — instead of taking our word for the identity and quality of a compound, you can read the report itself.
Every batch we list is tested by a third-party laboratory and reported on two points:
Purity
The percentage of the sample that is the stated compound, measured analytically. Our batches are released at 99%+ purity.
Amount
The quantity of compound actually present in the vial. Each batch is weighed and verified to be within range of the amount printed on the vial label.
