Methylclostebol[edit]

Chemical structure of Methylclostebol

Methylclostebol is a synthetic anabolic-androgenic steroid (AAS) that is derived from testosterone. It is chemically known as 4-chloro-17α-methyltestosterone. Methylclostebol is a modified form of clostebol, which itself is a derivative of testosterone. The addition of a methyl group at the 17α position allows the compound to be orally active, while the chlorine atom at the 4 position reduces its androgenic activity.

Chemical Properties[edit]

Methylclostebol is characterized by its chemical structure, which includes a 17α-methyl group and a 4-chloro substitution. These modifications are intended to enhance the anabolic properties of the steroid while minimizing its androgenic effects. The molecular formula of methylclostebol is C20H31ClO2, and it has a molecular weight of 338.92 g/mol.

Pharmacology[edit]

Methylclostebol functions as an anabolic agent, promoting protein synthesis and muscle growth. It is known to have a higher anabolic to androgenic ratio compared to testosterone, which means it can potentially provide muscle-building effects with fewer androgenic side effects such as hair loss and prostate enlargement. However, like other 17α-alkylated steroids, methylclostebol can be hepatotoxic, meaning it can cause liver damage with prolonged use.

Usage and Effects[edit]

Methylclostebol is used by some athletes and bodybuilders to enhance performance and increase muscle mass. It is typically taken orally due to its 17α-methylation, which allows it to survive first-pass metabolism in the liver. Users of methylclostebol may experience increased strength, muscle size, and improved recovery times. However, the use of methylclostebol is banned in most sports organizations due to its performance-enhancing effects.

Side Effects[edit]

The use of methylclostebol can lead to several side effects, particularly with long-term use or high dosages. These side effects may include liver damage, increased risk of cardiovascular disease, hormonal imbalances, and masculinization in women. As with other anabolic steroids, there is also the potential for psychological effects such as aggression and mood swings.

Legal Status[edit]

Methylclostebol is classified as a controlled substance in many countries, including the United States, where it is listed as a Schedule III drug under the Controlled Substances Act. This classification makes it illegal to possess, distribute, or use methylclostebol without a prescription.
