Everything you need to know about Clenbuterol

Beta 2 agonists include Clenbuterol. These medications relax and extend muscles, making asthma breathing easier. Clenbuterol is also called Dilaterol, Spiropent, and Ventipulmin. It comes in tablet or solution form.

It's worth noting that Clenbuterol does not have FDA approval for use in the United States. However it is approved for treating asthma in other countries. Additionally it may be prescribed on occasion, for obstructive pulmonary disease (COPD) a condition characterized by breathing difficulties.

How does clenbuterol work?

Clenbuterol functions by triggering the receptors within our bodies. These receptors play a role in governing different functions like heart rate, blood pressure, metabolism and muscle contraction. When these receptors are activated clenbuterol can bring about effects such, as;

  • Increasing the oxygen flow to the lungs and muscles, which can improve endurance and performance.
  • Increasing the body temperature and metabolic rate, which can burn more calories and fat.
  • Increasing the protein synthesis and muscle growth, which can enhance strength and lean mass.
  • Decreasing the appetite and food intake, which can reduce weight gain.

Clenbuterol's effects on muscle growth and fat reduction make it a popular weight loss and performance supplement. Some feel clenbuterol can help them get a defined body or improve their athletic performance. Notable clenbuterol users include;

  • Alberto Contador, a Spanish cyclist who was stripped of his 2010 Tour de France title after testing positive for clenbuterol.
  • Canelo Alvarez, a Mexican boxer who was suspended for six months after testing positive for clenbuterol in 2018.
