Specifically, it is a DHT that has been structurally modified by the addition of a methyl group at the carbon 2 position. This protects the steroid from metabolic breakdown by the <b>3-Hydroxysteroid Dehydrogenase<\/b> enzyme, which is found in the muscles. The methylation also significantly increases the steroid&#8217;s anabolic potential. Subsequently, the propionic acid ester is added in order to delay the steroid\u2019s release time into the body from the injection site.<\/p>\n<p data-path-to-node=\"2\">MASTEROLIC is well-known as one of the few anabolic steroids with strong anti-estrogenic properties. In addition to the fact that this steroid does not exhibit estrogenic activity, it can actually act as an anti-estrogen in the body. In fact, the combination of Masteron and Nolvadex (Tamoxifen Citrate) has been proven to be a much more effective method for treating breast cancer in postmenopausal women than chemotherapy. MASTEROLIC\u2019s properties make it very popular in bodybuilding because it allows the avoidance of using anti-estrogen drugs during or after a cycle.<\/p>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Drostanolone Propionate (Masteron, Mastron) is an anabolic steroid derived from Dihydrotestosterone (DHT).
