Calculator for NAD+ (nicotinamide adenine dinucleotide) reconstitution and per-administration dosing maths. NAD+ is typically supplied in larger-volume formats than other research peptides — pens of 500mg total are common.
For research and educational purposes only. This calculator performs volumetric mathematics on the values you enter; it does not recommend doses or provide medical advice.
Universal peptide & nootropic dose calculator
Standard research pen format: 3 mL total volume, 300 clicks per pen. That’s fixed — so the only thing that changes is how many mg are in your specific pen. mg per click = your pen’s mg ÷ 300.
Vial mode: most research peptide vials are 3 mL borosilicate glass (industry standard — about 99% of compounds ship in this size). Larger compounds like NAD+ or high-mg GHK-Cu sometimes come in 5–10 mL vials. The bacteriostatic water you add must fit inside your physical vial — for a standard 3 mL vial, that’s usually 1–3 mL of BAC water. Tell us the vial’s peptide content (in mg), the BAC water you added, and your target dose — we work out the concentration, the volume to draw, and the syringe units on a U-100 insulin syringe.

About NAD+
NAD+ is a coenzyme present in every living cell. Research-grade NAD+ preparations are supplied for laboratory and research-administration study, primarily in pen, vial, and intravenous-research formats. NAD+ is unscheduled under the UK Misuse of Drugs Act 1971 and is not licensed as a medicine in the UK.
Published research literature describes NAD+ in longevity, metabolic, mitochondrial, and DNA-repair research contexts. Subcutaneous, intramuscular and intravenous research administration are all described in literature.
Typical reconstitution / pen formats
| Format | BAC water | Concentration / mg per click | Volume to draw / clicks | For |
|---|---|---|---|---|
| 500mg pen (prefilled, 3ml/300 clicks) | — | 1.67 mg/click | ≈30 clicks for 50mg / ≈60 clicks for 100mg | research-format pen |
| 500mg vial | 5 mL BAC water | 100 mg/mL | 0.50 mL (50 units U-100) | for a 50mg administration |
| 500mg vial | 10 mL BAC water | 50 mg/mL | 1.0 mL (100 units U-100) | for a 50mg administration |
NAD+ dosing observed in research literature
Reported research-literature dose ranges for NAD+ vary substantially by administration route. Subcutaneous research administration commonly described in the 50–250mg range; intravenous research protocols use higher amounts over longer infusion windows. Topical and oral NAD+ precursors (NMN, NR) use different dosing entirely.
These figures are reported here for completeness of the research-literature picture and do not constitute a dosage recommendation.
Half-life and frequency
NAD+ has a short serum half-life as it is rapidly metabolised. This supports the higher per-administration amounts compared with the long-acting peptides.
Storage and shelf life
Lyophilised refrigerated; reconstituted approximately 28 days refrigerated. NAD+ is sensitive to repeated freeze-thaw cycles.
Frequently asked questions
How many clicks on a 500mg NAD+ pen for a 50mg dose?
500mg ÷ 300 clicks = 1.67 mg/click. For 50mg: 50 ÷ 1.67 = 30 clicks.
Can NAD+ be administered orally?
NAD+ itself is poorly absorbed orally. Oral precursors (NMN, NR) are used in research as oral routes to elevate NAD+ levels.
Is NAD+ legal in the UK?
Unscheduled, supplied as research-grade. Not licensed as a medicine in the UK.
