Masteron is an injectable steroid that is the active ingredient Drostanolone propionate.

Drostanolone Propionate is perhaps one of the more exotic androgenic / anabolic steroids, which can be used by an athlete. Was originally developed and used as an anti-estrogen used to treat breast cancer. It was especially in combination with a SERM (Selective Estrogen Receptor Modulators) used tamoxifen (Nolvadex) for the treatment of breast cancer, and did give a significant decrease in estrogen levels in women subjected to such treatment. There is not much used these days for such purposes, for different reasons, but for many athletes including competitive bodybuilders in particular remains a rather Drostanolone Propionate secret favorite of AS drugs.

The fact that Drostanolone Propionate creature was like an anti-estrogen is very much about some properties Drostanolone propionate has proposed. Drostanolone Propionateis a derivative of DHT (dihydrotestosterone) and not convert to estrogen by the aromatizing agent. It is believed that the anti-estrogenic properties Drostanolone Propionatemay partly to do with either an inhibition in any way by the enzyme aromatase or an interaction with estrogen itself in a way that the binding of estrogen receptor blocks. Either way, this would Drostanolone Propionate as a useful tool for the AS user connections (which is what most AS users, if you consider the most important foundation of most testosterone cycles) to convert to estrogen use. By inhibiting the enzyme aromatase, Drostanolone propionate in effect would block the conversion of free testosterone to estrogen by aromatization way. This would not only serve to slightly increase the amounts of active free testosterone in circulation, but it would also negate the side effects caused by high levels of estrogen by aromatization. Such side effects include the development of gynecomastia and water retention / bloating. Conversely, if Drostanolone Propionate actually blocks the binding of estrogen to the estrogen receptor (ER) in some way, although aromatization of testosterone can occur, the impact would be limited due to the inability of estrogen to bind to the ER. So by this mechanism, the effects of excess estrogen production by aromatization through the use of this steroid would be limited.

Although Drostanolone propionate contains such anti-estrogenic properties, but also (with a DHT derivative) has anabolic and androgenic properties. Although in theory and on paper you can see, not to be a very potent androgen, in fact Drostanolone Propionate give higher androgenic effect than might be expected. The use of Drostanolone propionate, since it is an AAS will shut down natural testosterone production and thus, despite anti-estrogenic effect again, you have to think not that Drostanolone Propionate could be used as an option in post-cycle therapy, as recovery inhibit.

There are two forms of Masteron, which is generally available - and Drostanolone Drostanolone Propionate Enanthate. The propionate-version is usually dosed at 50-150mg/ml and the fast-acting version of Masteron, need to be injected every other day. The enanthate version of Masteron is usually dosed at 200mg/ml and about to be injected only twice per week, as the esters of drostanolone is more appropriate that way?? What a slower release of the hormone.
