Bolasterone

Anabolic steroid

Chemical structure of Bolasterone

Bolasterone is a synthetic anabolic steroid that was first developed in the 1950s. It is known for its ability to promote muscle growth and increase strength, making it popular among bodybuilders and athletes. However, its use is associated with significant side effects and it is classified as a controlled substance in many countries.

Chemical Properties

Bolasterone is a derivative of testosterone, the primary male sex hormone and anabolic steroid. It is chemically known as 7_,17_-dimethyl-17_-hydroxyandrost-4-en-3-one. The addition of methyl groups at the 7_ and 17_ positions increases its oral bioavailability and anabolic activity.

Pharmacology

Bolasterone exhibits strong anabolic effects with moderate androgenic properties. It binds to the androgen receptors in muscle tissue, promoting protein synthesis and muscle growth. Its anabolic to androgenic ratio is higher than that of testosterone, making it more effective in building muscle mass with fewer androgenic side effects.

Medical Uses

Historically, bolasterone was used in the treatment of conditions such as muscle wasting and osteoporosis. However, due to its potential for abuse and adverse effects, its medical use has become limited.

Side Effects

The use of bolasterone can lead to a range of side effects, including:

• Liver toxicity due to its 17_-alkylated structure.
• Gynecomastia (development of breast tissue in men) due to its estrogenic activity.
• Acne and oily skin as a result of increased sebum production.
• Hair loss and hirsutism (excessive hair growth) due to its androgenic effects.
• Suppression of natural testosterone production, leading to hypogonadism.

Legal Status

Bolasterone is classified as a Schedule III controlled substance under the Anabolic Steroid Control Act in the United States. It is banned by most major sports organizations, including the World Anti-Doping Agency (WADA).

Related Compounds

Bolasterone is structurally related to other anabolic steroids such as methandrostenolone and oxandrolone. These compounds share similar anabolic properties but differ in their androgenic effects and side effect profiles.
