5mg Tirzepatide with 4mL bacteriostatic water: dose chart
Answer
5 mg of Tirzepatide in 4 mL of bacteriostatic water gives 1.25 mg/mL. A 1.25 mg dose is 1 mL, or 100 units on a U-100 syringe, about 4 doses per vial.

Dose chart: 5 mg vial in 4 mL
| Dose | Volume | U-100 units | U-40 units | Doses per vial |
|---|---|---|---|---|
| 0.5 mg | 0.4 mL | 40 | 16 | 10 |
| 1 mg | 0.8 mL | 80 | 32 | 5 |
| 1.25 mg | 1 mL | 100 | 40 | 4 |
Doses that would need more than a full 1 mL syringe are omitted. Use less bacteriostatic water for those.
Common questions
- Does adding more water make the dose weaker?
- No. The vial still holds the same total milligrams. More water lowers the concentration, so you draw more volume for the same dose. The amount of peptide going in is identical.
- Can I use a U-40 syringe instead of U-100?
- Yes, but the numbers change. A U-40 syringe reads 40 units per mL instead of 100, so the same dose is a smaller unit number on the barrel. Both columns are in the chart above. Read the one that matches your syringe.
- What concentration is 5 mg in 4 mL?
- 1.25 mg/mL. Divide the vial's milligrams by the millilitres of bacteriostatic water you added: 5 ÷ 4 = 1.25.
- How long is it good for after mixing?
- Refrigerate reconstituted peptide at 36–46°F (2–8°C). Most references give 28–60 days once mixed, depending on the preservative in the bacteriostatic water. Do not freeze it, and inspect for cloudiness or particles before every draw.
