Masteron is a steroid highly valued by competing bodybuilders. Acting substance Drostanolone propionate is a synthetic derivative of dihydrotestosterone. This causes the Masteron not to aromatize in any dosage and thus, it cannot be converted into estrogens. Since Masteron is a predominantly androgenic steroid, the athlete can increase his androgen level without also risking an increase in his estrogen level. This results in a dramatically improved hardness and sharpness of the muscles. A prerequisite is that the athlete's fat content must already be very low. In this case Masteron can then be the decisive factor between a smooth, flat muscle or a hard and ripped look.

Masteron is especially effective in combination with steroids such as Winstrol, Parabolan, Primobolan, Oxandrolone and also Testosterone propionate. The usual dosage taken by athletes is around 100 mg three times per week. Since the substance drostanolone propionate is quickly broken down in the body, frequent and regular injections are necessary. This fact makes Masteron a very interesting steroid when doping tests must be passed by a negative urine analysis.
