Clenbuterol for Fat Loss

Clenbuterol is a potent sympathomimetic amine, primarily used by bodybuilders and athletes as a powerful fat-loss agent. Though often referred to as a steroid, it is not; it is a beta-2 adrenergic agonist. Its primary mechanism of action is to stimulate beta-2 receptors, which leads to an increase in the body's core temperature and metabolic rate (thermogenesis). This means the body burns more calories at rest. It also has a mild anabolic effect and can help preserve muscle mass during a calorie deficit, making it popular for "cutting" cycles. However, Clenbuterol carries significant risks, particularly for the cardiovascular system. It can cause side effects like heart palpitations, increased blood pressure, and anxiety. Its use is banned by most sports organizations and it is not approved for human use in many countries. Its relevance to biological age is purely through its potent effect on body composition, but the associated risks often outweigh the benefits for general healthspan purposes.
