A COA is only as trustworthy as your ability to verify it. Anyone can paste a nice-looking PDF; verification closes that gap.

Match the batch

Check that the batch number on the certificate matches the batch on your vial. A COA for a different batch tells you nothing about your material.

Verify with the lab

Independent labs (Janoshik, Uzorak) provide a report ID or QR code you can enter on their own website to confirm the report is genuine.

Check the essentials

Confirm HPLC purity, identity/mass, method and a recent date. Browse and open every NOVA Labs certificate in the COA browser.
