NAD+ 1,000 mg reconstitution: how much water and how many units

Water volume chart · Syringe units · Draws per vial

Short answer: 10 mL of bacteriostatic water in a 1,000 mg NAD+ vial makes 100 mg/mL. On a U-100 insulin syringe (1 mL = 100 units), every 10 units then holds 10 mg. More water gives a weaker solution and a bigger draw for the same amount; the amount in the vial stays 1,000 mg.

Syringe units by amount

The amounts below are examples to show the conversion, not doses. How much to take is a decision for you and your prescriber.

A 1,000 mg vial holds 40 draws of 25 mg, 20 draws of 50 mg, 10 draws of 100 mg, no matter how much water you add.

The math

  1. Concentration. 1,000 mg ÷ 10 mL = 100 mg/mL
  2. Volume to draw. amount ÷ 100 mg/mL = mL
  3. Syringe units. mL × 100 = units

For a different water volume or amount, the free peptide reconstitution calculator works backwards from the amount you want and suggests a water volume that lands on a clean syringe mark.

Frequently asked questions

How much bacteriostatic water do I add to a 1,000 mg NAD+ vial?+
There is no single right amount. More water makes each draw bigger and easier to measure; less water keeps the volume small. With 10 mL, a 1,000 mg vial is 100 mg/mL, so every 10 units on a U-100 insulin syringe holds 10 mg. With 2 mL it is 500 mg/mL (50 mg per 10 units). With 5 mL it is 200 mg/mL (20 mg per 10 units).
How many units is 50 mg of NAD+ from a 1,000 mg vial?+
With 10 mL of water the vial is 100 mg/mL, so 50 mg is 0.5 mL, or 50 units on a U-100 syringe. With a different water volume the units change but the amount does not. The amount is an example for the math, not a recommendation.
How many 50 mg draws are in a 1,000 mg NAD+ vial?+
20 (1,000 mg ÷ 50 mg), whatever volume of water you add. In practice a little is lost to the syringe dead space and the last drops in the vial.
