How to read this chart

Human growth hormone. Plasma half-life is hours, so the chart is a daily pulse — it does not build a long-ester depot.

The default row models 2.00 mg as a subcutaneous dose, daily (ed), for 12 weeks.

Also called Somatropin, Growth Hormone, Human Growth Hormone.

What the default curve does

On that default row the model counts 84 doses. Steady state is about day 0.8. Washout runs to about day 0.9. In the last interval the peak is 2.02 mg and the trough is 0.040 mg, a swing of 98%.

How often a dose is still there

A half-life of 0.1d means each dose has mostly cleared before the next daily dose, so the line is a row of spikes.

Closest comparison

MK-677 has a half-life of 1d against 0.1d on this page.
