Tirzepatide Calculator

Tirzepatide Injection Dose Calculator

Calculate the exact volume of Tirzepatide needed in "Units" based on your prescribed dosage (mg) and the concentration of your vial (mg/mL). This is specifically designed for use with standard U-100 insulin syringes.

Typical doses: 2.5, 5, 7.5, 10, 12.5, or 15 mg

Check your vial label (e.g., 20mg per 2mL = 10mg/mL)

Your Calculated Dose:

0 Units

Equivalent to 0.00 mL

Note: This calculation assumes the use of a standard U-100 insulin syringe where 100 units = 1 mL.

Understanding Tirzepatide Dosing

Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. Accurate dosing is critical for managing weight and glycemic control while minimizing gastrointestinal side effects. When using compounded Tirzepatide, patients often receive a vial and must calculate the "units" to pull into a syringe.

The Tirzepatide Math

To find the volume needed for your injection, use this formula:

(Prescribed Dose in mg ÷ Concentration in mg/mL) × 100 = Injection Units

Standard Titration Schedule

While your healthcare provider will determine your specific plan, the standard titration for Tirzepatide usually follows this monthly progression:

• Month 1: 2.5 mg weekly (Loading dose)
• Month 2: 5.0 mg weekly
• Month 3: 7.5 mg weekly
• Month 4: 10.0 mg weekly
• Month 5: 12.5 mg weekly
• Month 6+: 15.0 mg weekly (Maximum dose)

Example Calculation

If your doctor prescribes a 5 mg dose and your vial concentration is 10 mg per 1 mL:

1. 5 mg ÷ 10 mg/mL = 0.5 mL
2. 0.5 mL × 100 units/mL = 50 Units in an insulin syringe.
