Handling
Storage
NAD+ (Nicotinamide Adenine Dinucleotide) is a foundational coenzyme present in every living cell, central to redox reactions, sirtuin-mediated deacetylation, PARP-driven DNA repair and mitochondrial energy metabolism. NAD+ levels decline with age, driving intense research interest in NAD+ replenishment as a longevity and cellular-repair model. Supplied as ≥98% HPLC lyophilised powder with third-party CoA.
The range
Every vial in the range is lyophilised, labelled and lot-numbered the same way, with the certificate for its lot linked from its own product page. Pictured: BPC-157, TB-500, GHK-Cu, Glow and Retatrutide.

Cellular NAD+ levels decline with age, driving intense research interest in NAD+ replenishment as a longevity and cellular-repair model. UK Peptides supplies NAD+ 500mg as ≥98% HPLC lyophilised powder with a signed third-party Certificate of Analysis.
The 500mg vial supports extended in-vitro and cell-culture protocols. Published research on NAD+ and its precursors (NR, NMN) covers:
Store the lyophilised NAD+ powder at -20°C, sealed and protected from light. NAD+ is moderately hygroscopic — allow the vial to reach room temperature before opening. Refrigerate the reconstituted solution at 2–8°C and use within 28 days.
NAD+ oxidises on prolonged exposure to air, so keep the vial sealed between draws.
Every NAD+ 500mg lot is independently HPLC-UV tested to ≥98% purity by an accredited independent laboratory, with mass-spectrometry identity confirmation against the published molecular weight of 663.43 Da. The signed PDF Certificate of Analysis is supplied with every order.

Nicotinamide adenine dinucleotide (NAD+) is a foundational cellular coenzyme that participates in redox reactions and is a required substrate for the sirtuin family of NAD+-dependent deacetylases and for poly(ADP-ribose) polymerases (PARPs) in DNA repair. Cellular NAD+ concentrations decline with age, which underpins research interest in NAD+ replenishment strategies.
