17aa DHT-derivative oral. Short half-life; daily pulse. Marked estimate.
The default row models 20.0 mg as an oral dose, daily (ed), for 4 weeks.
The half-life on this page is an estimate, not a labeled population value. Methodology.
Also called Methasterone, Sdrol, Methyldrostanolone, M Drol.

On that default row the model counts 28 doses. Steady state is about day 2.1. Washout runs to about day 2.1. In the last interval the peak is 24.8 mg and the trough is 5.08 mg, a swing of 79%.
A half-life of 0.4d means each dose has mostly cleared before the next daily dose, so the line is a row of spikes.
Mast E has a half-life of 4.5d against 0.4d on this page.
