Masteron is a steroid highly valued by competing bodybuilders. The great popularity of this injectable steroid in bodybuilder circles is due to the extraordinary characteristics of its included 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. One must, however, make a distinction here since Masteron does not automatically improve the quality of muscles in everyone. 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. For this purpose Masteron is often only used during the last four weeks before a competition so that the muscles get the last "kick." Masteron is especially effective in combination with steroids such as Winstrol, Parabolan, Primobolan, Oxandrolone and also Testosterone propionate.
