Assay results
Every line the release panel ran for this lot, with the method, the acceptance criterion and the measured value — not a pass mark alone.

| Amino acid analysis | Net peptide content | ≥ 80.0 % | 87.3 % | Pass |
| Karl Fischer | Water content | ≤ 8.0 % | 2.23 % | Pass |
| Ion chromatography | Residual TFA | ≤ 1.0 % | 0.13 % | Pass |
| LAL kinetic chromogenic | Bacterial endotoxin | < 5.0 EU/mg | < 0.22 EU/mg | Pass |
| USP <71> membrane filtration | Sterility | No growth | No growth | Pass |

Handling for this lot
- Appearance
- White to pale yellow lyophilised powder
- Storage
- -20 °C, desiccated. Hygroscopic — reseal immediately after opening.
- Reconstitution
- Prepare fresh. Aqueous NAD+ hydrolyses measurably within days even refrigerated, and the hydrolysis product inhibits sirtuins.
