• Active ingredient: Drostanolone Propionate

• Form: Injections

• Vehicle oil: Sesame oil

Description:

Drostanolone (Masteron) has a high androgenic effect and a moderate anabolic effect. Drostanolone does not aromatize in the body (i.e., it does not convert to estrogens); instead, it is a mild aromatase inhibitor. It has a biological action similar to dihydrotestosterone, being a derivative of this hormone.

In medicine, drostanolone is used to treat breast cancer in women; however, due to the high probability of virilization, it is currently rarely used. Drostanolone is not susceptible to aromatase action, meaning it cannot be converted 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, prostate enlargement, and increased body hair growth. As a DHT derivative, it inhibits estradiol activity in tissues, showing indirect antiestrogenic activity.

Among the psychological effects of this drug, the most notable is the "motivational boost" for training, which is very popular among athletes on cutting diets when they lack strength and experience the psychological decline caused by a lack of carbohydrates.

Drostanolone is popular in bodybuilding because it doesn't cause water retention and has a mild diuretic effect, which improves muscle definition. It can be useful for athletes who want to increase muscle hardness and density, being mainly used before competitions. It allows for achieving a ripped athletic physique, thanks also to the drug's fat-burning effect. Practice shows that a Drostanolone cycle can reduce fat mass by 5-10% compared to the initial state.

Drostanolone has a low anabolic index (compared to testosterone), which explains its effectiveness in burning fat, while at the same time increasing the risk of androgenic side effects: aggression, acne, baldness, prostate hypertrophy, and virilization in women.

Dosage:

The optimal effect of the drug is achieved with a dose of approximately 300-500 mg per week. People on hormone replacement therapy can use it to reduce SHBG, thus increasing the amount of free testosterone in the blood. The drug is much easier to tolerate than stanozolol or other DHT derivatives used to reduce SHBG. For these purposes, a dose of 75 to 200 mg of the drug per week is used. Drostanolone is believed to be more difficult to detect in anti-doping controls than other steroids. However, detection methods are constantly improving, so be aware of this.
