This Post is also available in: German

In bodybuilding, drostanolone propionate is used by athletes who want to gain muscle hardness. Since it is docked to the aldosterone receptor and so helps to drain it, it is usually used 4 – 8 weeks before a competition preparation. Drostanolone propionate helps during a bodybuilding to improve the training performance and regeneration time. As a rule, it is stuck with other steroids, e.g. With various testosterones such as trenbolone or stanozolol.

The synthesis of the DHT derivative drostanolone propionate was first described in 1959. The market introduction of Drolban, a drostanolone propionate product for combating breast cancer in women, took place at the end of the 1960s.
