Clenbuterol Use in Fitness and Bodybuilding
What is Clenbuterol?
Clenbuterol (commonly known as “Clen”) is a potent, long-lasting bronchodilator that is prescribed for human use outside of the U.S. It is abused generally by bodybuilders and athletes for its ability to increase lean muscle mass and reduce body fat (i.e., repartitioning effects). However, clenbuterol is also associated with significant adverse cardiovascular and neurological effects.
Is Clenbuterol Legal?
In the United States, clenbuterol is banned for human use. It is only approved for use in horses. In 1998, the Federal Food and Drug Administration (FDA) approved the clenbuterol-based Ventipulmin Syrup, as a prescription-only drug for the treatment of airway obstruction in horses. This product is not intended for human use or for use in food-producing animals. Clenbuterol is also listed by the World Anti-Doping Agency and the International Olympic Committee as a performance enhancing drug. So, unless you’re a horse with bad lungs, this drug is illegal. In fact, any horse that received the drug cannot be slaughtered for food.
Outside the U.S., clenbuterol is available by prescription for the treatment of bronchial asthma in humans. It is available in tablets (0.01 or 0.02 mg per tablet) and liquid preparations. The recommended dosage is 0.02-0.03 mg twice daily.
How does Clenbuterol work?
Clenbuterol is a beta2-adrenergic agonist, which stimulates the beta2-adrenergic receptors on bronchial smooth muscle produces bronchodilation or opens up the airways. Llike other beta adrenergic agonists, clenbuterol can produce adverse cardiovascular and neurological effects, such as heart palpitations, muscle tremors, and nervousness. Activation of beta-adrenergic receptors also accounts for clenbuterol’s ability to increase lean muscle mass and reduce body fat, however, how it reduces it does this is not yet clearly defined.
Why is Clenbuterol abused?
Clenbuterol is abused for its ability to change the body’s composition by reducing body fat and increasing skeletal muscle mass. It is typically abused by athletes and bodybuilders at dose of 60-120 µg per day (two to three times the recommended daily dose). It is often used in combination with other performance enhancing drugs, such as anabolic steroids, “pro hormones”, and growth hormone.
Clenbuterol is also illicitly given to livestock for ability to increase lean muscle mass and reduce body fat. This has resulted in several outbreaks of acute illness in Spain, France, Italy, China, and Portugal 0.5-3 hours after individuals ingested liver and meat containing clenbuterol residues. The symptoms, which included increased heart rate, nervousness, headache, muscular tremor, dizziness, nausea, vomiting, fever, and chills, typically resolved within 2 to 6 days. Because of this, the U.S. and some European countries actively monitor urine and tissue samples from livestock for the presence of clenbuterol.
There have also been reports of clenbuterol-tainted heroin and cocaine. Although no deaths were attributed to the clenbuterol exposures, the individuals were hospitalized for up to several days due to clenbuterol intoxication.
Who are the major abusers of Clenbuterol?
Clenbuterol is typically abused by athletes, including fitness athletes and bodybuilders. It is believed to be more popular among female athletes since its effects are not associated with the typical androgenic side effects such as growing facial hair, deepening of the voice, and thickening of the skin. Professional athletes in several different sports have tested positive for clenbuterol. lt is also marketed and abused for weight-loss purposes.
Where do people get Clenbuterol?
Clenbuterol is obtained by illegal importation from other countries where it is approved for human use. It is readily available on the Internet as tablets, syrup, and an injectable formulation. The Drug Enforcement Agency (DEA) and other forensic laboratories have reported numerous clenbuterol items since 2006 till now. However because clenbuterol is to controlled in the United States, it is highly possible that the number of clenbuterol-containing drugs may be much higher than reported.
So my follow fitness enthusiasts, if you’re looking for something to build perfectly sculpted muscles, remember that the side effects associated with clenbuterol use far exceed the temporary benefits you gain from it. Try to avoid products that promise quick fixes if your overall health and wellbeing is more important to you than looking good; because you may end up looking real good in a box instead of in your clothes.
