Tirzepatide calculator example
This example uses the editable starter reference values already loaded by the calculator. It is shown so users can see how mg, mcg, mL, and U-100 marks connect.
- 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
What tirzepatide value is preloaded?
The preset loads 2,500 mcg, which is 2.5 mg. It is editable and should be checked against the actual product instructions.
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.
