Drostanolone propionate (Masteron)

Masteron (drastanolone) is an androgen-anabolic steroid (AAS). The drug has practically no phenomenon of conversion into estrogens. But, unfortunately, due to kinship with dihydrotestosterone – often, when applied, shows unpleasant effects inherent in DHT (read about this in the article below).

  • Detection time is 14 days (approximately, because the doping commission is constantly looking for new drugs and improves the methods of detecting prohibited substances, it also depends on the athlete using the drug, whether he uses phenobarbital and furosemide to accelerate the withdrawal of the drug)

Despite the fact that the drug was originally released as a propionate ester, it is also available today in the form of enanthate. What are the effects of Masteron? Masteron, unlike testosterone, is a drug with a rather narrow spectrum of action. Due to its ability to bind to sex hormone binding globulin (SHBG), Masteron excels in the course with other anabolic drugs. This property helps to increase the level of free testosterone in the body, which allows the athlete to achieve the set goals in bodybuilding. A more complete picture of his action can be obtained by looking at the effects that he manifests:

  • The pronounced fat-burning effect is Masteron’s “trump card”, making it a special priority during the “drying” period and shortly before entering the stage. Based on the numerous experience of athletes, we can say that the drug can lead to a decrease in fat up to 8% of its original level. But of course, do not forget that without a “clean” diet and cardio training this probability is not so high.
  • An insignificant set of muscle mass. On the one hand, this effect will not be liked by those, set by the corresponding goal, and on the other hand, Masteron will be a good choice for those who are interested in improving sports results, not accompanied by excessive weight gain. Of course, in combination with other drugs, muscle growth will be more significant than with the use of “solo”.
  • Presumably, the inhibitory effect on the enzyme aromatase. This means that the drug not only does not cause typical “estrogenic” side effects, but is also a good prevention. By the way, due to this at one time Masteron was used in malignant breast tumors, but was removed from medical practice in connection with the ability to provoke masculinization.
  • Increase in the “density” and “drawing” of the musculature. This is due not only to the fact that the drug does not cause fluid retention, but also its mild diuretic effect. It is in this regard, almost all cases of taking drostanolona fall on bodybuilders, who are preparing to go on stage.

Side effects

  • Quite a strong manifestation of symptoms of virilization in women.
  • Acne, acne on the face and body.
  • Hair loss or intense hair growth.
  • Increased LDL cholesterol (“bad” cholesterol) and lower HDL cholesterol (“good” cholesterol).
  • Significantly inhibits the production of its own testosterone. After the course, exogenous steroid hormones are withdrawn, the production is resumed.


The standard dose of Masteron for adult men is usually 300-400 mg per week. This means that injections of 100 mg should be given every other day for 6-8 weeks. For women, there should be enough dosages of 50 mg per week for 4-6 weeks. Some women may use up to 100 mg of the drug per week, but when using such dosages, the first signs of masculinization appear. Masteron is regarded as a relatively weak anabolic agent. This is largely due to the fact that the drug does not significantly affect the growth of muscle mass, athletes are inclined to identify the quality of the steroid with its capabilities in building muscle mass. Other athletes can not evaluate Masteron due to misuse. If the percentage of fat in your body is more than 25%, you will not see half the effects that the drug provides. This is a very valuable anabolic steroid, but you have to understand why you use it, what its benefits are, what you can achieve with its use. Required PCT.
