CAS: 76-43-7 refers to the Chemical Abstracts Service (CAS) Registry Number for the chemical compound known as Halotestin or Fluoxymesterone. The CAS Registry Number is a unique numerical identifier assigned to every chemical substance described in the open scientific literature, encompassing organic and inorganic compounds, minerals, isotopes, alloys, and mixtures.
Fluoxymesterone is a potent anabolic-androgenic steroid (AAS) with the molecular formula C20H29FO3 and a molecular weight of 336.44 g/mol. It is a derivative of testosterone, modified to enhance its anabolic properties while reducing its androgenic effects. The addition of a 9-fluoro group and 11-hydroxy group to the steroid structure significantly increases its oral bioavailability and resistance to metabolic breakdown in the liver.
This compound is predominantly used in medical settings to treat conditions such as male hypogonadism, delayed puberty in males, and certain types of breast cancer in women. The therapeutic effects of Fluoxymesterone are attributed to its ability to bind to androgen receptors in muscle and bone tissues, promoting protein synthesis, nitrogen retention, and red blood cell production. These actions help increase muscle mass, strength, and overall physical performance.
However, Fluoxymesterone's powerful androgenic properties also contribute to a range of potential side effects. Common adverse effects include liver toxicity, as it is hepatotoxic, and can cause significant liver damage with prolonged use. Other side effects include mood swings, aggression, acne, hair loss, and virilization in women. Cardiovascular issues, such as elevated cholesterol levels and hypertension, are also associated with its use.
