It belongs to a class of drugs known as beta-2 agonists, which act on the sympathetic nervous system to promote fat loss and muscle growth. 

The Science Behind Clenbuterol

Clenbuterol works by binding to beta-2 adrenergic receptors in the body, which are located in the smooth muscles of the bronchial tubes and blood vessels. When these receptors are stimulated, it causes the muscles to relax and dilate, allowing more oxygen to flow into the lungs and blood vessels. This can lead to increased endurance and aerobic capacity, making it a popular drug for endurance athletes.
This is achieved by activating a pathway called the mTOR pathway, which is responsible for regulating muscle growth.
In addition, clenbuterol can also increase the metabolic rate of the body, causing it to burn more calories and fat. This effect is achieved by increasing the production of the hormone adrenaline, which stimulates the breakdown of stored fat cells into free fatty acids. These fatty acids can then be used as fuel by the body to support increased energy needs during exercise. Continue reading →
