Drostanolone (Masteron) has a high androgenic and a moderate anabolic effect. Drostanolone does not aromatize in the body (that is, it does not turn into estrogens), on the contrary, it is an light aromatase inhibitor. It has similar biological action to dihydrotestosterone, as it is a derivative of this hormone. 

In medicine, Drostanolone is used as a treatment for breast cancer in women, however, due to the high probability of virilization, it is currently used rare. Drostonolone is not susceptible to the action of aromatase, it means that there is no way to convert it to estradiol.

 It has a good affinity for androgen receptors not only in muscles, but also in the prostate and scalp, hence the possible side effects: baldness, enlargement of the prostate, body hair growth. As a derivative of DHT, it inhibits the activity of estradiol in tissues, so, it exhibits indirect antiestrogene activity. 

Among the psychological effects of this drug noted “motivational drive” for the training, which is very popular with athletes on cutting diets, when they do not have the strength and psychological decline from a lack of carbohydrates. 

Drostanolone is popular in bodybuilding, as it does not cause fluid retention and has a light diuretic effect, which improves muscle definition. It may be helpful to the athletes who want to increase the hardness and density of the muscles, it is used before the competition mostly. It allows you to achieve ripped athletic form, thanks to the fat burning effect of the drug also. Practice shows, that the Drostanolone cycle can reduce the fat mass by 5-10% from the initial state. 

Drostanolone has a low anabolic index (compared to testosterone), which is why it burns fat so well, at the same time it increases the risk of androgenic side effects: aggression, acne, baldness, prostate hypertrophy and virilization in women.


The optimal effect of the drug is achieved when using a dosage of about 300-500 mg per week. Persons on hormone replacement therapy can use it to reduce SHBG, since in terms of its side effects, increases the amount of free testosterone in the blood. The drug is much easier to tolerate than stanozolol or other DHT derivatives that used to reduce SHBG. For these purposes, use from 75 to 200 mg of the drug per week, it is believed that drostanolone is worse caught on doping control than other steroids. However, detection methods are constantly improving, so be aware of this.
