Anastrozole is an aromatase inhibitor used primarily in the treatment of hormone receptor-positive breast cancer. It belongs to a class of drugs known as nonsteroidal aromatase inhibitors. Anastrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens (such as testosterone) into estrogen. By reducing estrogen levels, Anastrozole helps prevent the growth of estrogen-dependent tumors.
- Estrogen Control: Anastrozole is commonly used by bodybuilders and athletes to control estrogen levels, particularly when using anabolic steroids that can aromatize into estrogen. By inhibiting aromatase, Anastrozole can help prevent estrogen-related side effects such as water retention, gynecomastia (enlargement of breast tissue), and fat accumulation.
- Increased Free Testosterone: By reducing estrogen levels, Anastrozole can help maintain a higher ratio of testosterone to estrogen in the body. This can potentially lead to increased free testosterone levels, which may contribute to muscle gain and improved performance.
- Reduction in Estrogenic Side Effects: Anastrozole can mitigate the negative effects associated with excess estrogen, such as bloating and fat gain. By controlling estrogen levels, it may promote a leaner and more muscular physique.
