  • Route: subcutaneous
  • Half-life: ~120 hours
  • Cycle: 20 weeks on / 0 off

Clinical escalation: 2.5 mg weekly for 4 weeks, then 5, 7.5, 10, 12.5, 15 mg at 4-week intervals as tolerated.

Tirzepatide calculator FAQ

How do I use the Tirzepatide calculator?+

Confirm your vial size in mg (default 10), set the diluent volume in mL (default 2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard Tirzepatide reconstitution?+

Most Tirzepatide research protocols reconstitute a 10 mg vial with 2 mL of bacteriostatic water, yielding 5000 mcg/mL.

What syringe should I use for Tirzepatide?+

U-100 insulin syringes are standard for Tirzepatide subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the Tirzepatide calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
