Description
Research-grade NAD+ (nicotinamide adenine dinucleotide) — 500mg lyophilized material supplied with a separate vial of sterile diluent (0.3% potassium sorbate). NAD+ is a coenzyme central to cellular redox metabolism. 99%+ purity verified by an independent third-party lab via HPLC and mass spectrometry.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, where it functions as the central electron carrier in redox metabolism and as a substrate for sirtuins and PARP enzymes. Note that unlike most of this catalogue it is not a peptide — it is a dinucleotide, which is why it is described here by molecular identity rather than amino acid sequence.
Supplied with sterile water preserved with 0.3% potassium sorbate; no separate bacteriostatic water is needed.
WHAT RESEARCHERS LOOK AT
Cellular NAD+ pools and the salvage pathway
Sirtuin and PARP enzyme activity as NAD+-dependent processes
Mitochondrial redox balance and electron transport
Comparative work against NNMT inhibition approaches such as 5-Amino-1MQ
Post-reconstitution stability across the in-use window

Frequently Asked Questions
DO I NEED TO BUY BACTERIOSTATIC WATER SEPARATELY?
No. Every nasal spray ships with its own diluent — sterile water preserved with 0.3% potassium sorbate, supplied with every spray. This differs from the lyophilized vials in our catalogue, which are reconstituted with bacteriostatic water sold separately.
IS NAD+ A PEPTIDE?
No. Despite being sold alongside research peptides, NAD+ is a dinucleotide coenzyme, not a peptide. It has no amino acid sequence and is described by molecular identity instead.
HOW SHOULD IT BE STORED AFTER RECONSTITUTION?
Keep the bottle refrigerated at 2–8°C and protected from light both before and after reconstitution. Once reconstituted, use within an appropriate research timeframe — material in solution has a materially shorter usable life than the sealed lyophilized form.
HOW IS IT SHIPPED IN CANADA?
Orders placed and paid before 3:00 PM ET ship the same business day via Canada Post Xpresspost with full tracking. Shipping is domestic from within Canada, so there are no customs delays or border holds.
IS THE COA VERIFIABLE?
Yes. Every batch is independently lab-tested with a unique report key you can confirm independently — see our guide on how to verify a lab report key.
