Proviron SmPC (Bayer): Tmax 1.6 h, terminal half-life 12–13 h. How the model works.

The example curve

25 mg every day for 8 weeks. With a 12h half-life, it levels off around day 3. The row runs longer than that, so the plateau is on the chart. Between doses it runs from about 9.31 to 33.3 mg, a swing of 72%. Each dose is its own spike. After the last dose, the tail takes about 2.8 days to fall to a few percent.
