beta-Nicotinamide adenine dinucleotide (CAS 53-84-9), a dinucleotide cofactor (not a peptide) central to cellular energy metabolism and the substrate of sirtuin deacetylases, PARPs, and CD38. Direct intravenous or subcutaneous administration is used in research contexts to raise systemic NAD+ and rescue the age-related decline in NAD+ availability that limits sirtuin-driven longevity pathways. Sold by research-peptide vendors as injectable NAD+; oral precursors (NR, NMN) are marketed as supplements but fall outside this catalog.
