Description

Drostanolone, commonly known as Masteron, exhibits a high androgenic and moderate anabolic effect. It does not aromatize in the body, acting as a light aromatase inhibitor. Being a derivative of dihydrotestosterone (DHT), it shares similar biological actions. Despite its medical use in treating breast cancer in women, its high potential for virilization limits its current usage. The absence of aromatase action prevents conversion to estradiol.

Drostanolone demonstrates a strong affinity for androgen receptors in muscles, prostate, and scalp, leading to potential side effects such as baldness, prostate enlargement, and body hair growth. As a DHT derivative, it indirectly inhibits estradiol activity, displaying antiestrogenic properties. Notably, athletes on cutting diets value the motivational drive provided by Drostanolone, countering strength and psychological decline due to carbohydrate deficiency.

In bodybuilding, Drostanolone is favored for its ability to promote muscle definition without fluid retention. Its mild diuretic effect aids in achieving a ripped athletic form, while its fat-burning properties contribute to reduced fat mass by 5-10%. However, its anabolic index is lower compared to testosterone, increasing the risk of androgenic side effects such as aggression, acne, baldness, prostate hypertrophy, and virilization in women.

Dosage

The optimal effect of Drostanolone is achieved with a weekly dosage ranging from 300-500 mg. Individuals undergoing hormone replacement therapy may use it to reduce sex hormone-binding globulin (SHBG) and increase free testosterone levels. Compared to other SHBG-reducing DHT derivatives like stanozolol, Drostanolone is considered more challenging to detect in doping control. Dosages typically range from 75-200 mg per week, depending on the intended purpose. The following dosage ranges are commonly used:

• Beginner: 50 mg every other day (EOD)
• Average Dosage: 100 mg EOD
• High Dosage: 50+ mg every day (ED)
