How to read this chart

Weekly GLP-1. Elimination half-life is about 7 days on the Ozempic/Wegovy labels, so weekly doses overlap and climb for roughly 4–5 weeks.

The default row models 0.250 mg as a subcutaneous dose, weekly, for 8 weeks.

Also called Wegovy, Sema, Semaglutide.

What the default curve does

On that default row the model counts 8 doses. Steady state is about day 35. Washout runs to about day 37. In the last interval the peak is 0.498 mg and the trough is 0.302 mg, a swing of 39%.

How often a dose is still there

A half-life of 7d means a dose is still present at the next one, so the line climbs and then levels off.

Closest comparison

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