Units per dose at 166.67 mg/mL
Insulin syringes are graduated in hundredths of a millilitre, so units = mL × 100 on a U-100, U-50 or U-30 barrel alike.
| Dose | Volume | U-100 units | Fits | Doses per vial |
|---|---|---|---|---|
| 50 mg | 0.3 mL | 30 u | U-30 | 10 |
| 100 mg | 0.6 mL | 60 u | U-100 | 5 |
How this is calculated
1 · Concentration
500 mg ÷ 3 mL = 166.67 mg/mL
The peptide mass never changes — bacteriostatic water only sets how concentrated the solution is, and therefore how far the plunger travels.
2 · Volume for a 100 mg dose
100 mg ÷ 166.67 mg/mL = 0.6 mL
3 · Insulin units
0.6 mL × 100 = 60 units
Every unit on the barrel carries 1666.7 mcg at this concentration, so misreading by one unit is a 1666.7 mcg error.

The interactive calculator draws this 166.67 mg/mL mix on a scaled U-100 barrel, shows when a draw lands exactly on a printed tick, and works backwards from a target dose to the water volume that makes it land cleanly.

- How much bacteriostatic water for a 500 mg NAD+ vial?
- Adding 3 mL of bacteriostatic water to a 500 mg NAD+ vial yields 166.67 mg/mL — 1666.7 mcg in every insulin unit. The reconstituted vial holds 300 units of solution in total.
- How many units is a 100 mg dose of NAD+ at 500 mg in 3 mL?
- 100 mg is 0.6 mL of this mix, which is 60 units on a U-100 insulin syringe (a U-100 barrel is enough).
- How many 100 mg doses does a 500 mg vial give?
- A 500 mg vial contains 5 full 100 mg doses. Using more or less bacteriostatic water changes the units you draw, never the number of doses in the vial.
