Masteron propionate. Short DHT-derivative ester; its curve looks much like testosterone propionate's. A 50 mg dose is about 42 mg of drostanolone, and that is what the line draws. Also called Drostanolone propionate, Masteron P, Masteron Propionate. The half-life is an estimate. Methodology.

No human PK study for drostanolone esters; 0.8 d and Tmax 1 d are community estimates. 84% drostanolone by weight (PubChem MW). How the model works.
50 mg every day for 8 weeks. With a 19h half-life, it levels off around day 5. The row runs longer than that, so the plateau is on the chart. The gap between doses is no longer than the model's time to peak (1d), so each dose is still rising when the next one lands and the line comes out flat. Real levels still rise and fall between doses. After the last dose, the tail takes about 5.3 days to fall to a few percent.
