NAD+

Each lot of product we receive is sent to a US-based 3rd party lab for extensive testing. We test for the following: Purity, Identification, Net Content, Endotoxins, Sterility, Conformity, Heavy Metals and Fentanyl. A Certificate of Analysis (COA) is provided for each released lot and documents the analytical testing results associated with that specific batch, including verified identity and purity. Testing badges appear only when the specific lot's COA supports those claims. To learn more about our testing standards, methods, and documentation, please visit Quality & Testing.

Every lot has a stable batch page in the COA / Batch Library, reachable from the product page or COA / Batch Library search tool. You can find your lot printed on the bottle, and it will also be posted within your account archive for reference. The COA page shows the current verified record and its downloadable report.

A lot's certificate can be re-issued, for example after a retest. The newer report becomes the current record and the earlier one stays in the batch page's history as superseded, so a QR code or link printed against the lot never breaks.

Each section of a certificate page appears only when that analysis is in the lot's record. If a test was not run on a lot, the page shows nothing for it rather than a placeholder. We describe testing exactly as performed.
