Tirzepatide dosage calculator
Tirzepatide's roughly five-day half-life sits just under its weekly interval, so it still accumulates to a stable plateau but with slightly more peak-to-trough swing than semaglutide. A 10mg vial in 2mL keeps maintenance doses on round syringe marks.

How to reconstitute Tirzepatide
STEP 1
Add bacteriostatic water
Trickle 2mL of BAC water down the inside wall of the 10mg vial. That gives a 5.00 mg/mL solution.
STEP 2
Swirl, do not shake
Rotate gently until fully dissolved. Shaking shears the peptide.
STEP 3
Draw your 5000mcg dose
Pull to 100.0 IU (1.000 mL). One 10mg vial yields about 2 doses.
STEP 4
Refrigerate between uses
Store the reconstituted vial at 2-8°C and use within a few weeks.
Tirzepatide dosing questions
How do I reconstitute Tirzepatide?+
Add 2mL of bacteriostatic water to a 10mg Tirzepatide vial. That produces a 5.00 mg/mL (5000 mcg/mL) solution. For a 5000mcg dose you then draw 1.000 mL.
How many units of Tirzepatide do I draw for a 5000mcg dose?+
On a U-100 insulin syringe, draw to 100.0 units (1.000 mL). Adjust the inputs above if your vial or water volume differs.
How many Tirzepatide doses are in one vial?+
A 10mg vial dosed at 5000mcg gives about 2 doses.
What is Tirzepatide's half-life?+
Tirzepatide has a half-life of ~5 days. A typical protocol is 2.5mg weekly, titrated up every 4 weeks. Tirzepatide's roughly five-day half-life sits just under its weekly interval, so it still accumulates to a stable plateau but with slightly more peak-to-trough swing than semaglutide. A 10mg vial in 2mL keeps maintenance doses on round syringe marks.
How long until Tirzepatide reaches steady state?+
With a ~5 days half-life, Tirzepatide reaches steady state after roughly five half-lives. The steady-state read-out above shows the accumulation factor and mean level for the seeded weekly dose.
