Units per dose at 50 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 | 1 mL | 100 u | U-100 | 10 |
| 100 mg | 2 mL | 200 u | split draw | 5 |
Amber rows exceed 100 units — more than one full U-100 barrel. That dose needs a larger draw or a stronger mix (less water).
How this is calculated
1 · Concentration
500 mg ÷ 10 mL = 50 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 50 mg dose
50 mg ÷ 50 mg/mL = 1 mL
3 · Insulin units
1 mL × 100 = 100 units
Every unit on the barrel carries 500 mcg at this concentration, so misreading by one unit is a 500 mcg error.

The interactive calculator draws this 50 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 10 mL of bacteriostatic water to a 500 mg NAD+ vial yields 50 mg/mL — 500 mcg in every insulin unit. The reconstituted vial holds 1000 units of solution in total.
- How many units is a 50 mg dose of NAD+ at 500 mg in 10 mL?
- 50 mg is 1 mL of this mix, which is 100 units on a U-100 insulin syringe (a U-100 barrel is enough).
- How many 50 mg doses does a 500 mg vial give?
- A 500 mg vial contains 10 full 50 mg doses. Using more or less bacteriostatic water changes the units you draw, never the number of doses in the vial.
