NAD+ 500 mg vial: mixing and syringe units
A 500 mg vial of NAD+ mixed with 5 mL of bacteriostatic water is 100 mg/mL. At that strength 25 mg is 25 units on a U-100 syringe and 100 mg is 100 units. The doses on this page are a reported range, not a label dose.

Each row is one dose, the volume to draw and where that sits on a U-100 insulin syringe. The last three columns show which syringe sizes can hold it in one draw.
| Dose | Volume | Syringe units | 0.3 mL syringe | 0.5 mL syringe | 1 mL syringe |
|---|---|---|---|---|---|
| 25 mg | 0.25 mL | 25 units | Yes | Yes | Yes |
| 50 mg | 0.50 mL | 50 units | No | Yes | Yes |
| 100 mg | 1.00 mL | 100 units | No | No | Yes |
Source Reported step-up, not a label dose: 25 to 50 mg in weeks 1 and 2, then 50 to 100 mg. Published human studies gave NAD+ into a vein. Vial math is arithmetic.
How to mix a 500 mg NAD+ vial
- Wash your hands. Wipe the stopper of the NAD+ vial and the water vial with an alcohol swab.
- Draw 5 mL of bacteriostatic water into a syringe.
- Push the needle through the stopper of the peptide vial and let the water run slowly down the glass, not straight onto the powder.
- Swirl the vial gently until the powder is gone. Do not shake it.
- Write the date and 100 mg/mL on the vial, then put it in the fridge.
If you add a different amount of water
More water makes each dose a bigger, easier draw. Less water makes it smaller. The milligrams in the vial do not change.
| Water added | Concentration | 25 mg | 50 mg | 100 mg |
|---|---|---|---|---|
| 1 mL | 500 mg/mL | 5 units | 10 units | 20 units |
| 2 mL | 250 mg/mL | 10 units | 20 units | 40 units |
| 3 mL | 166.667 mg/mL | 15 units | 30 units | 60 units |
| 5 mL | 100 mg/mL | 25 units | 50 units | 100 units |
The marked row is the amount used in the chart above. Red cells are draws under 5 units, which are hard to read, or over 100 units, which one 1 mL syringe cannot hold.
How many doses are in the vial
| Dose | Whole doses in a 500 mg vial |
|---|---|
| 25 mg | 20 doses |
| 50 mg | 10 doses |
| 100 mg | 5 doses |
How long the vial lasts depends on how often it is used. The reported frequency for NAD+ is: 1 to 3 times weekly.
NAD+ 500 mg vial questions
How many units is 25 mg of NAD+ from a 500 mg vial?
With 5 mL of bacteriostatic water the vial is 100 mg/mL. 25 mg is 0.25 mL, which is 25 units on a U-100 syringe.
How many units is 50 mg of NAD+ from a 500 mg vial?
With 5 mL of bacteriostatic water the vial is 100 mg/mL. 50 mg is 0.50 mL, which is 50 units on a U-100 syringe.
How many units is 100 mg of NAD+ from a 500 mg vial?
With 5 mL of bacteriostatic water the vial is 100 mg/mL. 100 mg is 1.00 mL, which is 100 units on a U-100 syringe.
How much bacteriostatic water goes in a 500 mg NAD+ vial?
5 mL is the amount used on this page. It gives 100 mg/mL and puts the doses at 25, 50, 100 units. Any amount works as long as the math is redone for it.
What if I added 1 mL instead of 5 mL?
The vial would be 500 mg/mL instead of 100 mg/mL, so 25 mg would be 5 units instead of 25. The dose in the syringe is the same; only the volume changes.
How many doses are in a 500 mg NAD+ vial?
Whole doses in one vial: 20 at 25 mg, 10 at 50 mg, 5 at 100 mg.
