NAD+
A coenzyme rather than a peptide. Degrades readily in solution, so measured content frequently sits below label even when the source material was correct.
What we measure
- HPLC purity (%)
- Identity confirmation
- Measured content (mg)
What tends to go wrong
Degradation in storage is common — low results are not always fraud.
This is a pattern we see across submitted samples, not a claim about any particular vendor. The only way to know about your vial is to test your vial.
