3mg Semaglutide with 2.5mL bacteriostatic water: dose chart
Answer
3 mg of Semaglutide in 2.5 mL of bacteriostatic water gives 1.2 mg/mL. A 1 mg dose is 0.833 mL, or 83.3 units on a U-100 syringe, about 3 doses per vial.

Dose chart: 3 mg vial in 2.5 mL
| Dose | Volume | U-100 units | U-40 units | Doses per vial |
|---|---|---|---|---|
| 0.125 mg | 0.104 mL | 10.4 | 4.2 | 24 |
| 0.25 mg | 0.208 mL | 20.8 | 8.3 | 12 |
| 0.5 mg | 0.417 mL | 41.7 | 16.7 | 6 |
| 1 mg | 0.833 mL | 83.3 | 33.3 | 3 |
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 3 mg in 2.5 mL?
- 1.2 mg/mL. Divide the vial's milligrams by the millilitres of bacteriostatic water you added: 3 ÷ 2.5 = 1.2.
- 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.
