The exact steps we take to ensure a pristine product below, but first, a word about COAs.

Testing sequence

1. 1

   Receiving

   Incoming inventory is logged by lot number and production date on arrival.
2. 2

   Quarantine

   New lots are held out of sale until testing is complete.
3. 3

   Sample submission

   Multiple samples from each lot are sent to an independent lab (labs are rotated to ensure independence).
4. 4

   Purity and identity testing

   Labs test for purity, identity, heavy metals and endotoxin/microbial contamination.
5. 5

   Bench testing

   We’re researchers too. Cleared samples hit our bench for research.
6. 6

   COA publication

   The Certificate of Analysis, including lab name, test date, purity result, and method, is published to our verification tool and a link is provided to the lab’s own database.
7. 7

   Listing

   Only lots with a published, passing COA are made available for purchase.
8. 8

   Ongoing spot checks

   We periodically re-test held inventory to confirm stability over time.
