Masteron has a pharmaceutical name of Drostanolone propionate or Drostanolone enanthate. It is used as an injectable. These are the generally available two forms of Masteron. The propionate is the fast acting one compared to the enanthate. Properties of Masteron Masteron is a derivative of dihydrotestosterone, also known as DHT. It does not get converted to estrogen if subjected to aromatization. This makes it immensely useful for the anabolic steroid users that use such compounds that get transformed to estrogen. It is thought that Masteron inhibits the aromatase enzyme and hence, it will block the transformation of free testosterone into estrogen. this will increase the amounts of free testosterone in the blood and also cut down the side effects that are caused by estrogen.
