How much water should I add to a 10 mg tirzepatide vial?

A common research convention is 1–3 mL of USP bacteriostatic water per 10 mg vial. The calculator accepts any volume and returns the resulting concentration and units per dose.

Why does the calculator show units, not mL?

Most research protocols are drawn with U-100 insulin syringes, where 1 unit = 0.01 mL. Units are the finer, more convenient scale for µg-level doses.

Is the titration schedule a dosing recommendation?

No. It is a reference arithmetic table for planning research protocols and is included for transparency. Vyroval does not provide dosing guidance of any kind.

How it works

The math behind the tool

Concentration

10,000 µg ÷ water (mL) = µg/mL

A 10 mg tirzepatide vial contains 10,000 µg. With 2 mL of bacteriostatic water that is5,000 µg/mL — each unit holds 50 µg.

Reference kinetics

reported half-life ≈ 5 days (dual GIP/GLP-1 agonist)

Tirzepatide is a dual GIP/GLP-1 receptor agonist. Its reference half-life drives the titration spacing in published research protocols — used here only as arithmetic context.
