Tirzepatide: 15 mg vial with 1 mL water
Quick answer
Adding 1 mL of bacteriostatic water to a 15 mg Tirzepatide vial gives 15 mg/mL (15000 mcg/mL), so each unit on a U-100 insulin syringe holds 150 mcg. A 200 mcg dose is 1.3 units (0.013 mL), and the vial holds about 75 doses of that size.
Concentration
- Vial: 15 mg Tirzepatide
- Bacteriostatic water: 1 mL
- Concentration: 15 mg/mL (15000 mcg/mL)
- 1 unit on a U-100 syringe = 150 mcg
Tirzepatide dose to syringe units
| Dose | Syringe units (U-100) | Volume | Doses per vial |
|---|---|---|---|
| 2.5 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 6000 |
| 5 mcg (protocol dose) | 0 units, too small to measure reliably | 0 mL | 3000 |
| 7.5 mcg (protocol dose) | 0.1 units, too small to measure reliably | 0.001 mL | 2000 |
| 10 mcg (protocol dose) | 0.1 units, too small to measure reliably | 0.001 mL | 1500 |
| 200 mcg | 1.3 units | 0.013 mL | 75 |
| 250 mcg | 1.7 units | 0.017 mL | 60 |
| 300 mcg | 2 units | 0.02 mL | 50 |
| 500 mcg | 3.3 units | 0.033 mL | 30 |

Common questions
How many units is 200 mcg of Tirzepatide from a 15 mg vial with 1 mL water?
200 mcg is 1.3 units (0.013 mL) on a U-100 insulin syringe. With 1 mL of water in a 15 mg vial, each unit holds 150 mcg. For comparison: 250 mcg = 1.7 units, 300 mcg = 2 units, 500 mcg = 3.3 units.
What is the concentration of a 15 mg Tirzepatide vial mixed with 1 mL of water?
15 mg divided by 1 mL is 15 mg/mL, or 15000 mcg per mL. On a U-100 syringe (100 units = 1 mL) that is 150 mcg per unit.
How many 200 mcg doses are in a 15 mg vial?
About 75. 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 15 mg Tirzepatide vial?
The Crestigen Tirzepatide protocol uses 2 mL. 1 mL works too as long as you calculate units for this concentration (15 mg/mL) and label the vial.
