Certificates of Analysis

Every batch, on the record. Search by compound or by the lot code printed on your vial. Every certificate is public: no account, no email, no waiting.

What every certificate covers

Each certificate is released against the same specifications. The results on file belong to the certificate for the lot you receive.

Testing is performed by pH Solutions Lab Inc. of Monrovia, California, an independent laboratory ISO/IEC 17025:2017 accredited (A2LA R243 · PJLA Testing #84351). Each certificate carries a scan-to-verify code that opens the laboratory’s own copy. The chromatogram is printed on the certificate. Read each certificate for the panels run on that lot and the results on file.
