About two decades, Masteron successfully helped women fight breast cancer. And yet, the drug won its popularity thanks to its use in the field of bodybuilding.
Drostanolone propionate (Masteron) is a derivative of dihydrotestosterone (DHT). Masteron is a structurally altered DHT hormone, in the position of the second carbon of which a methyl group has been added. This protects it from metabolic degradation by the enzyme 3-hydroxysteroid dehydrogenase found in skeletal muscle. These simple structural transformations helped to create Drostanolone, which, moreover, has a short propionate ether. According to the functional sign, Masteron is known as one Masteron 200 of the few anabolic steroids with rather strong anti-estrogenic properties. In addition to the fact that the steroid itself does not carry any estrogenic activity, it can act as an anti-estrogen in the body. And this is the reason why the drug showed good results in the fight against breast cancer. Studies have shown that a bunch of Tamoxifen citrate + Drostanolone propionate was more effective than chemotherapy in the treatment of breast cancer.
