Masteron-100 is one of the most widely used anabolic steroids in the pre-competition period. If an athlete has reached a low percentage of fat, Masteron-100 causes an insane muscle hardness and density. It is not able to transform itself into estrogen and thus does not cause gynecomastia, excessive water bloating and consequent increased blood pressure. And since it does not cause gynecomastia, it is particularly popular with athletes prone to the occurrence of gynecomastia not only in the pre-competition period, but also in volume. Moreover, it does not cause hepatotoxicity almost at all. For even better advantageous use of the substance for the purpose of extreme muscle hardness and maximum strength gain, it is recommended to combine it with other substances: Propionate-100Trenacetat-150Stanox-10Xanadrol or Turinox.


CHEMICAL NAME: 2alpha-methyl-androstan-3-one-17B-ol, 2alpha-methyl-dihydrotestosterone





It is a synthetic derivative of DHT, which was discovered in 1959, its sales and production was completed in 1997, but nevertheless it is still available on the black market from underground manufacturers. It is also known under the synonym "dromastanolone". It was designed for human use primarily for women and in medicine it was used to support the treatment associated with cholesterol levels, also used in the treatment of some forms of cancer, but primarily to treat breast cancer in women.

It has a mild androgenic and anabolic effects, but in practice it proves to be much more potent androgen, compared to papers values, it binds to androgen receptors, 3 to 5 times more potently than testosterone. Increased muscle hardness and better density can be observed during its use, but the weight and power gains are only moderate. Like other anabolic androgenic steroids, drostanolone also increases protein synthesis. It does not convert to estrogen, therefore it does not aromatizes, so the formation of gynecomastia and water retention are unknown terms with this preparation. It is very mild for the liver and in general, the side effects are mild. It often brings disappointment to those who still have quite high levels of fat in the body. Its effects tend to manifest precisely in those with low levels of fat. This anabolic androgenic steroid is even attributed with slight diuretic and fat burning effects. Reduces aldosterone levels, thereby reduces the water level in the body, which is why its attributed with a slight diuretic effect. Of course, like any other derivative of dihydrotestosterone, drostanolone lowers the level of SHBG (binding globulin in the sex hormones in the blood) in the body, thereby increasing the use of free testosterone in the blood, which in turn enhances the anabolic effect of the cure.


Estrogenic side effects with this type of AAS are not necessary to mention, since it does not convert to estrogen. Therefore, the formation of gynecomastia, water retention and fat wrapping are not occurrence flaws. Androgenic side effects occur but to a much greater extent. It has profound effects on the scalp, which often causes hair loss, but not least relatively strong and extensive acne on the scalp, which often tends to grow to painful and scar-leaving ulcers. Also often mentioned is prostate enlargement. Noted is also slightly elevated blood pressure. It reduces the production of testosterone, like all anabolic androgenic steroids, it belongs among those with only a mild effect in this regard. Theoretically, it has a very strong potential to stimulate aggression, because it somehow negatively affects the central nervous system, but this is rather showing in women, in men it remains questionable. In long-term use, often observed are sleep disorders. Although it was used as a support drug for the treatment of cholesterol levels, in the long-term abuse decrease in HDL (good) and increase in LDL (bad) cholesterol.can be monitored.
