Coenzymes
NAD+ research peptide
NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a dinucleotide coenzyme made of nicotinamide mononucleotide and adenosine monophosphate joined through their phosphate groups. It is a core reagent in enzymology as the electron acceptor in hundreds of oxidoreductase reactions.
For in-vitro laboratory research only. Not for human or veterinary use.

Frequently asked questions
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a dinucleotide coenzyme made of nicotinamide mononucleotide and adenosine monophosphate joined through their phosphate groups. It is a core reagent in enzymology as the electron acceptor in hundreds of oxidoreductase reactions.
How is each NAD+ lot tested?
Every lot is tested at an ISO/IEC 17025 accredited third-party laboratory against an eight-assay panel: HPLC-UV purity, quantitative net peptide content, LC-MS identity, appearance, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and endotoxin by LAL. The certificate is published before the lot ships.
How do I verify the certificate for my NAD+ vial?
Scan the QR code on the vial label to open the certificate for that exact lot, or search the lot number in the North Wall COA library.
Is NAD+ for human use?
No. North Wall sells this compound solely for in-vitro laboratory research by qualified researchers aged 21 and over. It is not for human or veterinary use, and North Wall does not provide use, preparation, or dosing guidance.
