How the numbers work for NAD+
A 1000 mg vial of NAD+ with 2 mL of bacteriostatic water is 1000 / 2 = 500 mg/mL. A 50 mg dose is 50 / 500 = 0.1 mL, which is 10 units on a U-100 syringe, or the same number of clicks on a pen. With 3 mL of water instead, the concentration is 333.33 mg/mL and the same dose is 15 units. At that dose the vial holds 20 doses.
The formulas are the same for every compound: concentration is the vial amount divided by the water, the draw is the dose divided by the concentration, and a U-100 unit is 0.01 mL. They are written out on the methodology page.
NAD+ units at a glance
Syringe units for the amounts recorded for NAD+, from a 1000 mg vial, across the water volumes people most often use. These are recorded examples used for the arithmetic, not recommendations; a draw under 6 units is hard to measure repeatably and more water fixes that.

Where the amounts come from
The doses above are recorded amounts from the NAD+ entry in the compound library, which lists the sources behind them, labels each as clinical, preclinical or community-reported, and states what the evidence can and cannot support. The vial strength is the one most often listed by suppliers. Nothing on this page is medical advice.
Common questions about NAD+
- Is NAD+ an FDA-approved medicine?
- NAD+ is not an approved medicine; it is sold as a dietary supplement and compounded as an injection or infusion. Nicotinamide adenine dinucleotide sits in 503A category 1, under FDA evaluation for compounding, and compounded NAD+ is not an FDA-approved product.
- How much bacteriostatic water do I add to a 1000 mg vial of NAD+?
- There is no single right amount: the water sets the concentration and the size of the draw, not the dose. This page opens on 2 mL, which makes 500 mg/mL and puts a 50 mg dose at 10 units on a U-100 syringe. With 1 mL the same dose is 5 units; with 3 mL it is 15 units. More water gives a larger, easier-to-read draw, as long as the vial can hold it.
- How many units is 50 mg of NAD+?
- At 500 mg/mL (1000 mg in 2 mL of water), 50 mg is 0.1 mL, which is 10 units on a U-100 insulin syringe or 10 clicks on a peptide pen. At any other concentration the number changes; the units table on this page gives the other common water volumes.
- How many doses are in a 1000 mg vial of NAD+?
- At 50 mg per dose, a 1000 mg vial holds 20 doses. The water volume changes the size of each draw, not the number of doses in the vial.
- Where do the NAD+ amounts on this page come from?
- They are amounts recorded for NAD+ in the compound library (https://peptidescalculator.com/compound-library/nad), which lists the sources behind them and labels each as clinical, preclinical or community-reported. They are shown for the arithmetic, not as recommendations, and the vial strength is the one suppliers list most often. Nothing on this page is medical advice.
