Research Handling Guidance

Before reconstitution, allow both the lyophilised peptide and your chosen diluent to settle at normal laboratory room temperature. Equalising temperatures in this way supports the structural stability of the compound while it goes into solution.

Diluents and reconstitution solutions are purchased separately.

Research compound

NAD+

Name: NAD+
Brand: Regent Peptides
SKU: nad
Availability: InStock

£72.00/ 500mg vial

Dosage

Nicotinamide adenine dinucleotide, oxidised form

NAD+ is not a peptide but a dinucleotide coenzyme present in every living cell, central to redox metabolism and a substrate for sirtuins, PARPs and CD38. We include it in the catalogue because it is so frequently studied alongside longevity-class peptides.

Supplied as a lyophilised powder in 500 mg and larger vials, with purity confirmed by HPLC on every batch.

Research applications include redox and energy-metabolism assays, sirtuin and PARP enzymology, and cellular ageing models. Laboratory research use only.

Order before 3pm for same-day UK dispatch on Royal Mail Tracked 24, from £4.99.

NAD+ questions

Is NAD+ a peptide?

No. It is a nucleotide coenzyme. We list it in the longevity category because laboratories studying mitochondrial-derived peptides such as MOTS-c and SS-31 often use it in the same experiments.

How is NAD+ tested?

Each production batch is sent for independent HPLC purity analysis and mass spectrometry identity confirmation by Janoshik Analytical. The batch reference printed on the vial links to its Certificate of Analysis, which can be viewed on the lab's own verification site.

How should the lyophilised vial be stored?

Unopened lyophilised vials should be kept refrigerated at 2–8 °C, or at −20 °C for long-term storage, protected from light. Once reconstituted, solutions should be refrigerated and used within the period appropriate to the laboratory's own stability data.

Is this for human use?

No. All Regent Peptides products are supplied strictly for in-vitro laboratory research. They are not medicines and are not for human or veterinary use, diagnosis or treatment.
