# Does the NAD+ CoA confirm identity as well as purity?

Yes. Sable's batch-release specification for NAD+ is at least 99% purity by HPLC with identity confirmed by mass spectrometry. HPLC alone shows how pure a peak is, not what it is; the mass result is what confirms the compound. The certificate for your lot is emailed within 2 hours of a request at /coa-request.
