Tirzepatide dosage calculator example
This example uses a known 2.5 mg tirzepatide amount so users can see how vial strength and BAC water change the final U-100 syringe mark.
- Vial amount
- 10 mg total
- BAC water added
- 2 mL
- Example dose
- 2,500 mcg / 2.5 mg
- Concentration
- 5,000 mcg/mL
- Liquid to draw
- 0.5 mL
- U-100 syringe
- 50th mark
In this example, the visual syringe guide would point to the 50th mark. Change the vial, water, or dose values in the calculator to match the exact instructions you are using.

Frequently asked questions
Does this choose a tirzepatide dose?
No. It only converts a known dose into measurement math. Dose selection, timing, and titration must come from a licensed medical source.
How many units is 2.5 mg tirzepatide?
It depends on vial strength and BAC water amount. In this example, 10 mg mixed with 2 mL and a 2.5 mg dose lands on the 50th 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.
