Units per dose at 12 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 |
|---|---|---|---|---|
| 2.5 mg | 0.208 mL | 20.8 u | U-30 | 24 |
| 5 mg | 0.417 mL | 41.7 u | U-50 | 12 |
| 7.5 mg | 0.625 mL | 62.5 u | U-100 | 8 |
| 10 mg | 0.833 mL | 83.3 u | U-100 | 6 |
| 12.5 mg | 1.042 mL | 104.2 u | split draw | 4 |
| 15 mg | 1.25 mL | 125 u | split draw | 4 |
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
60 mg ÷ 5 mL = 12 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 10 mg dose
10 mg ÷ 12 mg/mL = 0.833 mL
3 · Insulin units
0.833 mL × 100 = 83.3 units
Every unit on the barrel carries 120 mcg at this concentration, so misreading by one unit is a 120 mcg error.

The interactive calculator draws this 12 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 60 mg Tirzepatide vial?
- Adding 5 mL of bacteriostatic water to a 60 mg Tirzepatide vial yields 12 mg/mL — 120 mcg in every insulin unit. The reconstituted vial holds 500 units of solution in total.
- How many units is a 10 mg dose of Tirzepatide at 60 mg in 5 mL?
- 10 mg is 0.833 mL of this mix, which is 83.3 units on a U-100 insulin syringe (a U-100 barrel is enough).
- How many 10 mg doses does a 60 mg vial give?
- A 60 mg vial contains 6 full 10 mg doses. Using more or less bacteriostatic water changes the units you draw, never the number of doses in the vial.
