Semaglutide units calculator example
This example uses 0.25 mg as 250 mcg so users can see how a semaglutide reference amount becomes liquid volume and a U-100 mark.
- Vial amount
- 5 mg total
- BAC water added
- 2 mL
- Example dose
- 250 mcg
- Concentration
- 2,500 mcg/mL
- Liquid to draw
- 0.1 mL
- U-100 syringe
- 10th mark
In this example, the visual syringe guide would point to the 10th mark. Change the vial, water, or dose values in the calculator to match the exact instructions you are using.

Why units vary
Semaglutide units on a syringe depend on vial strength and BAC water amount. Changing either value changes the mark.
Safety limit
Use this only to calculate measurement math from instructions you already have. It does not choose a dose or protocol.
Frequently asked questions
How many units is 0.25 mg semaglutide?
It depends on concentration. In the example shown here, 0.25 mg equals 250 mcg and lands on the 10th U-100 mark.
Is this a prescription or protocol?
No. PeptiCalc is a measurement calculator. It helps translate vial strength, BAC water, and a selected dose into syringe marks, but it does not prescribe treatment.
Can I edit the preloaded values?
Yes. Every value that opens in the calculator is editable, including vial amount, BAC water, syringe size, and dose.
Why do syringe marks matter?
Most U-100 insulin syringes show 100 marks per mL. The calculator converts the liquid dose into the mark to pull to on that syringe scale.
