How to read this chart

Weekly dual GIP/GLP-1 agonist. Half-life is about 5 days on the Mounjaro/Zepbound labels, so the weekly curve is a bit peakier than semaglutide and clears faster.

The default row models 2.50 mg as a subcutaneous dose, weekly, for 8 weeks.

Also called Zepbound, Tirz, Tirzepatide.

What the default curve does

On that default row the model counts 8 doses. Steady state is about day 25. Washout runs to about day 27. In the last interval the peak is 4.02 mg and the trough is 2.01 mg, a swing of 50%.

How often a dose is still there

A half-life of 5d means a dose is still present at the next one, so the line climbs and then levels off.

Closest comparison

Ozempic has a half-life of 7d against 5d on this page.
