DEMO=0 python3 build.py after wiring real content.Amount and purity of a compound that is routinely diluted.
NAD+ is cheap by weight, which means vendors can underfill and still look competitive. Content assay is the only check that matters.
Confirms the molecule is what the label claims, by measuring the mass of the eluting ions. Catches substitution and the wrong compound entirely.
How much is actually in the vial, compared against the declared strength and reported as a percentage of claim.
Area percent of the main peak, with the chromatogram attached so the figure can be checked rather than trusted.
A report ID and unique key that resolve to a public record. Anything that does not resolve is not a genuine report.
| Target compound | NAD+ (nicotinamide adenine dinucleotide) |
|---|---|
| Testing method | RP-HPLC-UV 260 nm + ESI-LC-MS |
| Result format | mg per vial, purity % |
| Minimum sample | 1 whole unopened vial, or 50 mg raw powder |
Yes, they separate chromatographically and differ in mass.
Add any of these to the same vial, on the same certificate.
Describe the sample and we will tell you what to order — or whether we can test it at all.
