NAD+ Dosage Calculator
NAD+ vials are much larger (hundreds of mg) and usually mixed with more water, so doses are measured in tens of units.
- Common vials
- 100 mg · 500 mg · 1000 mg
Injectable NAD+ is not an FDA-approved drug.

Syringe size
Smaller barrels have finer marks, which makes small doses easier to read.

Show the math
- Concentration = 500 mg ÷ 5 mL = 100 mg/mL
- Volume = 50 mg ÷ 100 mg/mL = 0.5 mL
- Units = 0.5 mL × 100 = 50 units
Dosing schedule
Is there a standard NAD+ dose?
There is no FDA-approved dosing for this compound. This page only converts the dose you enter into syringe units — it does not recommend a dose.
How to mix
How to reconstitute a peptide vial in 5 steps
- 01
Clean
Wash your hands. Wipe the rubber tops of the peptide vial and the bacteriostatic water with an alcohol swab and let them air-dry.
- 02
Draw the water
With a new syringe, draw 5 mL of bacteriostatic water — the same number you entered in the calculator. Use several draws if it’s more than your syringe holds.
- 03
Add it slowly
Insert the needle at an angle and let the water run down the inside wall of the vial, not straight onto the powder.
- 04
Swirl, don’t shake
Gently swirl or roll the vial until the powder dissolves completely. The liquid should look clear.
- 05
Label & refrigerate
Write the date and concentration (100 mg/mL) on the vial and keep it in the fridge.
Storing a mixed vial
- Keep it refrigerated at 2–8 °C (36–46 °F). Don’t freeze it.
- Protect it from light and heat.
- Follow the beyond-use date on your pharmacy label. If the liquid turns cloudy or has particles, don’t use it.
Please read before injecting
Always confirm your dose, concentration and syringe markings with your prescriber or pharmacist. Small calculation errors can have serious consequences. This tool does math — it doesn’t tell you what dose to take.
