NAD+ 500mg overview
NAD+ (Nicotinamide Adenine Dinucleotide, CAS# 53-84-9) is a naturally occurring dinucleotide coenzyme that functions as a redox cofactor in cellular energy metabolism. NexPept supplies it as a research reference standard for enzyme kinetics assays involving sirtuins and PARPs, cellular metabolism studies, and redox biology research in cell-free and in vitro systems. Not for use in any living organism.
Every lot is independently tested by a third-party analytical laboratory before it is listed. The Certificate of Analysis reports HPLC purity, mass spectrometry identity confirmation, and net-content verification, and stays published in our COA library after the batch sells out.

Research context
NAD+ is used as a coenzyme tool compound in preclinical in vitro settings. Published work has examined its role as an electron carrier in metabolic pathways and as a substrate for sirtuin and poly(ADP-ribose) polymerase enzyme kinetics assays, cellular energy metabolism studies, and redox biology research.
As a defined dinucleotide coenzyme with consistent structural characteristics between lots, it is used in controlled laboratory environments to study enzyme-substrate interactions and redox signalling. Lot-to-lot consistency matters for this kind of work, which is why every NexPept batch is published with its own purity figure rather than a blanket claim.
This compound has not been authorized by Health Canada for any therapeutic, clinical, or human use.

Frequently asked questions
What testing does each batch go through?
Identity and purity are confirmed by high-performance liquid chromatography and mass spectrometry before a lot is listed. The current lot, NP-NAD500-062426-01, tested at 99.39% on July 16, 2026. If a lot has not been tested, it does not go on sale.
What class of compound is NAD+?
A dinucleotide coenzyme, not a peptide — it functions as a redox cofactor in cellular energy metabolism and as a substrate for sirtuin and PARP enzymes. It is supplied as a lyophilized powder and handled as a research reference standard.
Is NAD+ a peptide like NexPept's other research compounds?
No. NAD+ is a small-molecule dinucleotide coenzyme rather than an amino-acid chain, though it is tested, documented, and supplied to the same research-grade standard as NexPept's peptide products.
What physical form does it arrive in?
A white to off-white lyophilized (freeze-dried) powder, sealed in a single vial. Net quantity is 500mg. No preparation, reconstitution or handling instructions are supplied; those are determined by qualified personnel under your own institutional protocols.
