Drostanolone (trademarks Masteron, Drolban, Metormon, Permastril, Mastager, etc.) is an anabolic steroid that is produced as propionate and enantate. Masterone has high androgenic activity and moderate anabolic action. Masterone is not aromatized in the body (i.e. it does not turn into estrogens), on the contrary, it is an aromatherapy inhibitor. Drostanolone is similar in its biological effect to dihydro-testosterone, as it is a derivative of this hormone (the chemical formula for Masteron is 2a-methyl-dihydro-testosterone propionate). In medicine, Masterone is used as a treatment for breast cancer in women, but due to the high probability of virileisation it is currently hardly used. The drug is widely available at specialised pharmacological online shops in Russia.
Drostanol is usually available in 50 and 100 mg/ml ampoules.
Drostanolone propionate is widely used by athletes in bodybuilding, to preserve muscle mass and strength during 'drying' cycles. Drostanolon is often used by runners and athletes who seek to maintain their weight class (without increasing body weight).
Masteron is popular in bodybuilding as it does not cause fluid accumulation and has a moderate diuretic effect, which helps improve the relief and definition of muscles. Drostanol can be of interest to those athletes who want to increase muscle hardness and density, and usually use it shortly before a competition. Drostanolone makes it possible to achieve the most expressive state of muscles, which is also due to the fat burning effect of the drug. Practice shows that a Masteron course can reduce fat mass by 5-7% of the original.
Masterone is able to increase strength, while maintaining total body weight and reducing the fat component. This makes Drostanol attractive in powerlifting. The drug can be used on a diet for weight loss in order to maintain muscle mass and suppress catabolism.
