NAD+ calculator.
Work out the reconstitution for a NAD+ vial. Enter the mg in the vial and the bacteriostatic water you add, and it returns the concentration in mg/mL and the volume in U-100 syringe units. Pre-filled with a common 500 mg vial — change it to match yours. Arithmetic only: it never suggests how much to use.

REFERENCENAD+ is a longevity peptide with an approximate half-life of Hours; rapidly converted intracellularly. The arithmetic above is the same for every compound — only the concentration changes with how you reconstitute. For mechanism, the evidence base, common research dose ranges and vendor pricing, see the full NAD+ guide, and the main peptide calculator for worked examples and the full method.
Common questions.
FAQHow do you work out NAD+ syringe units?
Reconstitute the vial, then divide the amount you want to draw by the concentration — mg of NAD+ in the vial divided by mL of bacteriostatic water — to get the volume in mL, and multiply by 100 for U-100 syringe units. The calculator above does it once you enter your vial and water.
How many units is 1 mg of NAD+?
It depends on how you reconstitute it, not on the compound. A 500 mg NAD+ vial mixed with 2 mL of bacteriostatic water is 250 mg/mL, so 1 mg is 0 units on a U-100 syringe. Use more water and the same 1 mg is more units.
What size vial does NAD+ come in?
Research NAD+ is commonly sold around 500 mg per vial, but sizes vary by vendor. The calculator works for any size — enter the mg printed on your label and the water you added.
