The record
The certificate names the same compound, strength and batch number as the vial, and its dates are in order.

Check the batch in your hand.
Enter the batch number printed on the vial. If a certificate of analysis is published for that batch, it appears here with every check it passed.
Verification
What “verified” means here.
02
The laboratory
An independent laboratory issued it, and we confirmed the report on that laboratory's own system before publishing it.
03
The file
The PDF carries a SHA-256 fingerprint and was read for the batch and report numbers. If a single byte of the file changes, the fingerprint no longer matches.
Laboratories
Laboratories we accept certificates from
Laboratories are listed here when the first certificate is published.
Limits
What a certificate does not establish
A certificate of analysis may describe analytical findings associated with a particular product or batch. COAs and other testing records do not, by themselves, establish:
FDA approval; suitability for human or animal use; pharmaceutical-grade manufacturing; sterility or absence of endotoxins; clinical safety or effectiveness; or compliance with all applicable laws.
Research use only. Not for human consumption.
