NAD+ Reconstitution & Dosage Calculator
This NAD+ dosage calculator explains reconstitution arithmetic using the amount printed on a vial and a water volume you supply. Catalog vial-size examples include 500 mg, 700 mg, 1000 mg; they are not universal product strengths. Enter your actual label rather than assuming that a preset applies. NAD+ is not a peptide, but the same mass-to-volume equation applies to a labeled preparation. The example amounts below are arbitrary arithmetic inputs, not recommended doses, schedules, routes, or treatments.

How to use the peptide calculator
- Check the NAD+ vial label and enter the mass for one vial in mg, not the combined mass of a multi-vial kit.
- Enter a water volume in mL. The calculator shows the resulting concentration; it does not choose a preparation volume or confirm suitability.
- Enter an amount to convert, selecting mg or mcg. Divide micrograms by 1,000 before working with mg/mL.
- Read the result in mL and U-100 syringe markings. Check the inputs and retain full precision until the final display.
The reconstitution formula
Concentration (mg/mL) = mg in vial ÷ mL of water.
Volume (mL) = desired amount (mg) ÷ concentration (mg/mL).
U-100 syringe units = volume (mL) × 100. Convert mcg to mg by dividing by 1,000 before calculating.
Worked examples
500 mg vial with an entered 2 mL
500 ÷ 2 = 250 mg/mL. An arbitrary 10 mg example corresponds to 10 ÷ 250 = 0.04 mL, or 4 U-100 units. A 0.1 mL reference draw represents 25 mg. These are numerical examples only.
700 mg vial with an entered 2 mL
700 ÷ 2 = 350 mg/mL. An arbitrary 10 mg example corresponds to 10 ÷ 350 = 0.0286 mL, or 2.8571 U-100 units. A 0.1 mL reference draw represents 35 mg. These are numerical examples only.
1000 mg vial with an entered 2 mL
1000 ÷ 2 = 500 mg/mL. An arbitrary 10 mg example corresponds to 10 ÷ 500 = 0.02 mL, or 2 U-100 units. A 0.1 mL reference draw represents 50 mg. These are numerical examples only.

Math-only NAD+ reference: an entered 2 mL and a 0.1 mL (10 U-100 units) draw. Verify the actual vial label.
| Vial (mg) | Water (mL) | Concentration (mg/mL) | Amount per 10 U-100 units (mcg) |
|---|---|---|---|
| 500 | 2 | 250 | 25000 |
| 700 | 2 | 350 | 35000 |
| 1000 | 2 | 500 | 50000 |
Frequently asked questions
How do I calculate NAD+ reconstitution concentration?
Divide the labeled NAD+ mass in mg by the entered volume in mL. The same vial mass in twice the volume produces half the concentration. The tool calculates this relationship; it does not decide how much water to add.
How many units is 0.1 mL?
On a U-100 syringe, 0.1 mL × 100 = 10 units. These markings describe volume, not milligrams or a substance's biological activity.
How do I convert micrograms to milligrams?
1,000 mcg equals 1 mg. Divide a microgram amount by 1,000: for example, 250 mcg is 0.25 mg. Use matching mass units when dividing by concentration.
Does it work with U-40 or U-50 syringes?
The displayed syringe-unit results use U-100 calibration only. For the same volume, U-40 markings equal mL × 40 and U-50 markings equal mL × 50. A 0.5 mL, 50-unit U-100 syringe is not a U-50 syringe.
Are the examples dosing recommendations?
No. Every example and table entry is hypothetical arithmetic. The calculator converts quantities you supply; it does not determine an appropriate amount, frequency, route, or treatment.
Are syringe units IU?
No. U-100 markings measure volume, not biological International Units (IU).
