NAD+: 500 mg vial with 3 mL water
Quick answer
Adding 3 mL of bacteriostatic water to a 500 mg NAD+ vial gives 166.67 mg/mL (166666.7 mcg/mL), so each unit on a U-100 insulin syringe holds 1666.7 mcg. A 2 mg dose is 1.2 units (0.012 mL), and the vial holds about 250 doses of that size.
Concentration
- Vial: 500 mg NAD+
- Bacteriostatic water: 3 mL (the volume in the Crestigen protocol)
- Concentration: 166.67 mg/mL (166666.7 mcg/mL)
- 1 unit on a U-100 syringe = 1666.7 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) | 0.1 units, too small to measure reliably | 0.001 mL | 5000 |
| 2 mg | 1.2 units | 0.012 mL | 250 |
| 2.5 mg | 1.5 units | 0.015 mL | 200 |
| 5 mg | 3 units | 0.03 mL | 100 |
| 7.5 mg | 4.5 units | 0.045 mL | 66 |
| 10 mg | 6 units | 0.06 mL | 50 |

Common questions
How many units is 2 mg of NAD+ from a 500 mg vial with 3 mL water?
2 mg is 1.2 units (0.012 mL) on a U-100 insulin syringe. With 3 mL of water in a 500 mg vial, each unit holds 1666.7 mcg. For comparison: 2.5 mg = 1.5 units, 5 mg = 3 units, 7.5 mg = 4.5 units.
What is the concentration of a 500 mg NAD+ vial mixed with 3 mL of water?
500 mg divided by 3 mL is 166.67 mg/mL, or 166666.7 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 1666.7 mcg per unit.
How many 2 mg doses are in a 500 mg vial?
About 250. 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?
3 mL is the volume used in the Crestigen NAD+ protocol. More water makes each dose a larger, easier-to-measure number of units; less water keeps injections smaller.
