Clenbuterol (chemical compound)

Clenbuterol is a chemical compound originally developed to treat respiratory conditions like asthma because it relaxes airway muscles. It belongs to a class called beta-2 agonists, which stimulate certain receptors to increase airflow. Athletes and bodybuilders sometimes misuse clenbuterol for its ability to promote fat loss and enhance muscle definition, although it is not approved for human weight loss in many countries due to potential health risks. Side effects can include increased heart rate, nervousness, and muscle cramps. Its use should be carefully managed and is typically regulated by medical authorities.
