Tirzepatide draw planner

Tirzepatide flips the usual precision problem. Early draws are generous — 2500 micrograms to start — while the powder mass grows to fifteen milligrams by the top of the ladder, so the question is not whether you can read it but whether it fits. Concentration arithmetic answers both: vial size and diluent decide.

Take the fifteen milligram vial in three millilitres of diluent: 5000 micrograms per millilitre, week one at half a millilitre — fine on a one-millilitre barrel, over the top of a 0.3. The tool runs that capacity check on every recalculation, alongside the ladder to 15000 micrograms, so replanning after a step-up takes one click.
