Verification for NAD+ is per lot, not per product. Across the strengths currently stocked: 500mg lot NAD-CA-26F-500 returned 512.17 mg measured, 102.4% of the labelled 500 mg; 1000mg lot NAD-CA-26I-1000 returned 1046.68 mg measured, 104.7% of the labelled 1000 mg, assayed by Janoshik. Those figures are the laboratory's, published in full rather than reduced to a badge.
Purity is half the number. It states what fraction of the material in the vial is NAD+; it says nothing about how much material is in the vial, and a short-filled vial can return a purity result that is entirely accurate. The figure that answers the second question is measured mass against expected content — for NAD+, across the strengths stocked they run from 102.4% to 104.7% of label. Both numbers are published for every lot, whichever way they fall.
Each strength of NAD+ carries its own lot code and its own certificate — NAD-CA-26F-500, NAD-CA-26I-1000 are separate tests, not one result applied across the range. The code printed on the vial you receive is the one to match, and matching it is what ties the material in hand to a test that was actually run on it.
Researchers who buy NAD+ in Canada through Eppix Labs receive the lot described by the certificate above: the code printed on the vial label is the code on the certificate, and both are searchable on the batch verification page.
