Every lot, independently
verified before it ships.
We publish a third-party Certificate of Analysis from an independent laboratory for every batch we sell — not our own in-house numbers. Match the lot on your vial to the report yourself.
Independent labs. Every COA comes from an outside laboratory, not an in-house test.
Lot-matched. The number on your vial matches the number on the report. Verify a lot →

Batch received & sampled
Every incoming batch is assigned a lot number before a single vial is sold.
Sent to an independent lab
A sample from that exact lot is shipped to a third-party analytical laboratory for independent HPLC/MS testing.
Report published, lot released
The report is posted to the product page with the issuing lab and its report number, so you can verify it with that lab directly.
