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.


How does it work?


Due to the effects of estrogen on Drostanolone Propionate Propionate side effects Drostanolone a very useful tool (especially in competitive bodybuilding) when cutting. As higher levels of estrogen lead to water retention, Drostanolone Propionate inhibits water retention, and many users claim that their muscles feel very full and tight on Drostanolone Propionate with him and them amazing muscle pumps in the gym. Using Drostanolone propionate (in conjunction with other appropriate medications) at low body fat percentage to see results in the user, fine details of the muscles stressed the grooves and the fine details of the muscle. Drostanolone Propionate helps give the water from between the skin and the muscles look like this cut (low body fat percentage). Not many other AS medicines can be seen on such effects on muscle-like detail with Drostanolone Propionate.

Despite these effects of this steroid, it is a rather weak AS in itself. One would hardly benefit from the use of all Drostanolone Propionate on his own, and can also take advantage of Drostanolone propionate alone in the loss of libido due to the shutdown of the lead body's natural production of testosterone. For these reasons, it is always recommended to stack with other steroids Drostanolone Propionate.

It is considered by many that the use Drostanolone propionate is a waste, if the user has a body fat percentage is higher than 10-12% has said. I can understand the argument, and the user must understand that seeing is not with higher body fat percentage in detail on the muscle as described, but I do not see it as a waste because of its anti-estrogenic properties. Such fibers can be no other accessories to cycle that will have other undesirable side effects would be, and besides, Masteron, in a synergistic manner with other work as drugs their effects reinforce to (for example, described with testosterone, as above). Masteron would be not recommended for beginners because it is not starting at this level is required.


An excellent example of a cutting cycle for an advanced user would be: (6-10 weeks)


150mg testosterone propionate every other day

Trenbolone 50mg every day (or 100 mg every other day)

Masteron 150mg every other day50mg Winstrol every day for the last 4 weeks of the cycle only




As already mentioned, Masteron has anti-estrogenic properties in the removal of many unwanted side effects experienced by AS users, such as gynecomastia, water retention and dangerous rise in blood pressure. Although Masteron is a weak steroid and on the paper has low androgenic properties it has already been mentioned, appear that in practice the androgenic properties slightly higher than in theory, and secondly Drostanolone Enanthate is a DHT derivative.

Shortly, however, includes side effects that may occur with the use of Masteron hair loss (if prone to hair loss), acne and aggression. If a user experience acne with other androgens such as testosterone, it is a real possibility that they experience with the use of Masteron. I know people who live only a few places experience with the use of testosterone, however, the use of Masteron them many other points. On the other hand, there are users who have fewer points than they seem to Masteron Trenbolone on experience.
