The immense popularity of this injectable steroid in professional circles was in the exceptional qualities of the active chemical contained in it. Mastebolin does not aromatize in any dosage and is not converted into estrogen.
Since Mastebolin is a predominantly androgenic steroid, an athlete without fear could increase the level of androgen in the blood, without fear that the level of estrogen will increase with it. The result is improved elasticity, hardness and sharpness of their muscle outlines. But it should be borne in mind that Masteron contributes to the high quality of the muscles, not every athlete. The main prerequisite for this is the low fat content of the athlete.
Only in this case, Mastebolin is a decisive factor between flat muscles or an elastic and lean appearance. Therefore, Masteron was usually recommended to be applied only in the last 4 weeks before the competition, in order to give the muscles a “finishing touch”. Especially good Masteron in combination with such steroids as Winstrol, Primobolan, Oxandrolone and Testosterone Propionate.
