NAD+: 500 mg vial with 2 mL water
Quick answer
Adding 2 mL of bacteriostatic water to a 500 mg NAD+ vial gives 250 mg/mL (250000 mcg/mL), so each unit on a U-100 insulin syringe holds 2500 mcg. A 2.5 mg dose is 1 units (0.01 mL), and the vial holds about 200 doses of that size.
Concentration
- Vial: 500 mg NAD+
- Bacteriostatic water: 2 mL
- Concentration: 250 mg/mL (250000 mcg/mL)
- 1 unit on a U-100 syringe = 2500 mcg
NAD+ dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 50 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 10000 |
| 75 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 6666 |
| 100 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 5000 |
| 2.5 mg | 1 units | 0.01 mL | 200 |
| 5 mg | 2 units | 0.02 mL | 100 |
| 7.5 mg | 3 units | 0.03 mL | 66 |
| 10 mg | 4 units | 0.04 mL | 50 |
| 15 mg | 6 units | 0.06 mL | 33 |

Common questions
How many units is 2.5 mg of NAD+ from a 500 mg vial with 2 mL water?
2.5 mg is 1 units (0.01 mL) on a U-100 insulin syringe. With 2 mL of water in a 500 mg vial, each unit holds 2500 mcg. For comparison: 5 mg = 2 units, 7.5 mg = 3 units, 10 mg = 4 units.
What is the concentration of a 500 mg NAD+ vial mixed with 2 mL of water?
500 mg divided by 2 mL is 250 mg/mL, or 250000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 2500 mcg per unit.
How many 2.5 mg doses are in a 500 mg vial?
About 200. The water volume changes how many units each dose takes, not how many doses the vial holds.
How much water should I add to a 500 mg NAD+ vial?
The Crestigen NAD+ protocol uses 3 mL. 2 mL works too as long as you calculate units for this concentration (250 mg/mL) and label the vial.
