Masteron is a (now discontinued) European injectable preparation containing the steroid drostanolone propionate. Drostanolone is a derivative of dihydrotestosterone, most specifically 2alpha-methyldihydrotestosterone. As a result, the structure of this steroid is that of a moderate anabolic/potent androgen which does not aromatize to estrogen. Water retention and gynecomastia are therefore not a concern with this compound; as of course here estrogen is usually the culprit. Masteron may in fact exhibit antiestrogenic activity in the body, competing with other substrates for binding to aromatase. This would reduce the conversion rate of other steroids, Masteron acting in the same manner as the oral steroid

Masteron is a derivative of dihydrotestosterone or DHT which restrains the conversion to estrogen through aromatization. It could be that its ability to inhibit estrogen from interacting with the aromatase enzyme or it blocks the receptor that binds the estrogen that causes this phenomena. Whatever the reason, because of its anti-estrogenic properties it blocks the conversion of free testosterones to estrogen through aromatization. This makes Masteron a common inclusion in a high anabolic cycle. Since compounds used in cycles to achieve mass gains and strengths have very potent testosterone content, Masteron is used to prevent the estrogenic side effects to take place. The side effects include bloating or water retention and gynecomastia.

Even though Masteron inhibits testosterone conversion to estrogen it still has anabolic and androgenic properties, simply because it is still a derivative of DHT. While some think that there is low aromatization with Masteron it still has a significant androgenic side-effects that one should expect when using this steroid. It could shut down the production of testosterone, so users should be careful to use this in post cycle therapy because it could actually slowdown recovery.

Masteron potentiates the effects (to a certain degree) of any other anabolic steroids it is stacked with in any variety of Masteron cycles. It has been previously mentioned that Masteron holds a moderate anabolic strength rating, making it only ever so slightly stronger than Testosterone, and in some cases may be weaker. Masteron’s highlight lies in its ability to assist and potentiate the activity and effects of other compounds stacked with it. Essentially, it allows the other stacked anabolic steroids alongside it to exhibit better effects. This occurs not only through its anti-estrogen and anti-aromatase effects, but through its ability to prevent a measurable amount of SHBG (Sex Hormone Binding Globulin) from binding to other anabolic steroids and rendering them inactive.
