Testing & Quality Control
We partner with third-party U.S. laboratories to provide batch-specific Certificates of Analysis (COAs) for our catalog.
COAs typically include identity and purity verification using industry-standard methods such as HPLC / LC-MS.
To maintain transparency, we provide batch and lot documentation so you can review supporting laboratory results tied to the inventory we source.
COAs are provided for available batches — transparency first.
