Chemical structure similar to testosterone propionate. White crystalline powder. Practically insoluble in water, soluble in ethyl alcohol, slowly soluble in vegetable oils.


Has androgenic (weaker than testosterone propionate) and anabolic (stronger than testosterone propionate) effects. It has an antitumor effect on thymus tumors, even in the presence of metastases, and in patients whose ovarian function has been suppressed by radiation, androgenic drugs or who have undergone oophorectomy. Maximum efficacy is achieved with bilateral oophorectomy.

Use in sport

An excellent feature of this drug is the predominance of androgenic activity over anabolic activity. As a rule, bodybuilders particularly appreciate the fat-burning effect of the steroid. The action is reinforced by the use of drugs which compensate for the androgenic influence. As a result, the greatest weight loss is seen when taking a combined dose. If the recommended dosage is exceeded, undesirable side effects are highly likely. This drug is not recommended for women, as the risk of virilization is high. For men, the steroid helps to make muscles more lifted, harder and more pronounced.

Drostanolone is a more effective anabolic, acting quite strongly on the growth of strength and muscle mass. This drug has many positive points and significant benefits. It is thanks to its merits that it has gained in popularity among modern athletes. The main advantages that favorably distinguish this steroid from other active ASAs are: inhibitory properties. This steroid is able to effectively block the aromatization process. This process increases the rate of recovery, with an overall positive effect on the individual. This property is highly effective, especially if the athlete is working on strength and speed. It physically motivates the athlete, gives him or her “grit”, increases endurance levels, increases the emotional desire to train and the desire to achieve new results; it has proven to be an active fat burner. It acts on muscles in the most positive way, making them firmer and harder; it is eliminated fairly rapidly from the body. It is particularly suitable for athletes subject to pre-competition doping controls. The test is guaranteed negative within 10 to 15 days of discontinuing the steroid; the drug combines fairly easily with Globulin. This can lead to a significant increase in free hormones in the blood, generally resulting in improved performance in competition. Based on the above-mentioned positive aspects of its effects on the body, we can conclude that Drostanolone can best be used as an aromatase inhibitor. In addition, it will be extremely effective for strength gains, with little potential for muscle mass growth. All in all, the above merits point to the drug’s extreme efficacy, making it virtually indispensable. Its effectiveness depends on training intensity and desired results.

Athletes generally take 300 to 500 mg of the remedy for 7 days, while the frequency of injections is every third or second day. The treatment cycle is 6 to 12 weeks.
