Mastaplex 100 ( Drostanolone Propionate) is a synthetic derivative of dihydrotestosterone, displaying a potent androgenic effect that is responsible for increases in muscle density and hardness and a moderate anabolic effect that creates a positive nitrogen balance in humans and promotes protein synthesis. Since it is a derivative of dihydrotestosterone, dromastolone does not aromatize in any dosage and thus it cannot be converted into estrogen. Therefore, estrogen-related water retention is eliminated. Drostanolone Enanthate and Propionate combines the fast-acting propionate form with the longer acting enanthate form.

Drostanolone Enanthate and Propionate is an anabolic/androgenic steroid. It is known to be highly androgenic and mildly anabolic. It is incapable of aromatization and has similar properties to dihydrotestosterone. It has been successfully used as a breast cancer drug but because of the high risk of virilization safer options are prescribed.
Use in sports

Masteron is used primarily by athletes who need to retain strength while losing mass. It is beneficial to runners and athletes who must remain in a certain weight class. It has gained popularity in the bodybuilding community as a diuretic and muscle defining drug.
Trivia
