Manufacturer:Sciroxx, Dromostanolone Dipropionate 100mg/1ml. Masteron is a steroid highly valued by bodybuilders going through competitions. It's great popularity is mainly the result of the extraordinary characteristics of it's substance, Drostanolone propionate which is a synthetic derivative of dihydrotestosterone. Masteron does not aromatize in any dosage and thus, it cannot be converted into estrogens. Masteron is mainly an androgenic steroid, meaning the users can increase their androgen level without risking an increase in their estrogen level. Result of this is a dramatically improved hardness and sharpness of the muscles. However, Masteron itself does not automatically improve the quality of muscles. Masteron is especially effective when stacked with Winstrol, Parabolan, Primobolan, Oxandrolone and also Testosterone propionate. It is not hepatoxic so liver damage is not to be accepted. High blood pressure and gyno are not a problem since it causes no water nor salt retention and the estrogen level remains low. Users can easily achieve that "ripped" look, popular in professional bodybuilding.
