    Effects and dosage

    Clenbuterol is a β2 agonist with some structural and pharmacological similarities to epinephrine and salbutamol, but its effects are more potent and longer-lasting as a stimulant and thermogenic drug. It causes an increase in aerobic capacity, central nervous systemstimulation, and an increase in blood pressure and oxygen transportation. It increases the rate at which body fat is metabolized while increasing the body's BMR. It is commonly used for smooth muscle relaxant properties. This means that it is a bronchodilator andtocolytic.

    Clenbuterol is usually used in dosages anywhere from 20-60 micrograms (mcg) a day when prescribed. A dose of about 20 mcg (women) or 40 mcg (men) should never be exceeded in a day.

    Clenbuterol is also prescribed for treatment of horses; however, equine use is usually the liquid form of clenbuterol.


    Human use

    Clenbuterol is approved for use in some countries, via prescription only, as a bronchodilator for asthma patients.[1] Recently though, the drug has been publicized for its off-label use as a weight-loss drug, similar to usage of other sympathomimetic amines such asephedrine. It is commonly used as a slimming aid despite lack of sufficient clinical testing either supporting or negating such use.


    Legal status

    Clenbuterol is not an ingredient of any therapeutic drug approved by the U.S. Food and Drug Administration and is now banned forIOC-tested athletes. In the U.S., administration of clenbuterol to any animal that could be used as food for human consumption is banned by the FDA.


    Use as performance-enhancing drug

    As a β2 sympathomimetic, clenbuterol has also been used as a performance-enhancing drug. Cyclist Alberto Contador of Spain was banned for two years from professional cycling after testing positive for the drug at the 2010 Tour de France. He was later stripped of the 2010 title of the Tour de France and the 2011 title of the Giro d'Italia.. However, CASfound that Contador did not take clenbuterol as a performance-enhancing drug, but probably tested positive due to a contaminated food supplement..

    American swimmer Jessica Hardy tested positive at the U.S. trials in 2008. She served a one-year suspension, having claimed she unknowingly took the drug in a contaminated food supplement. Former New York Mets clubhouse employee Kirk Radomski admitted in his plea deal to distributing clenbuterol to dozens of current and former Major League Baseball players and associates.

    After finishing fourth in the K-2 1000 m event at the 2008 Summer Olympics in Beijing, Polish sprint canoer Adam Seroczyński was disqualified for taking this drug; and Chinese cyclist Li Fuyu tested positive for it at the Dwars door Vlaanderen race in Belgium on March 24, 2010.

    In 2006, San Francisco Giants pitcher Guillermo Mota, while a member of the New York Mets, received a 50-game suspension after testing positive for clenbuterol. In 2012, MLB announced that they were again suspending Mota for 100 games due a positive test for clenbuterol.

    In 2010, St. Louis Cardinals minor-league shortstop Lainer Bueno received a 50-game suspension for the 2011 season as a result of testing positive for clenbuterol.

    In 2011, players of the Mexico national football team were found with clenbuterol in their bloodstream, but were acquitted by WADA after they claimed the clenbuterol came from contaminated food. FIFA has also claimed that 109 players from the Under-17 World Cup in Mexico tested positive for this drug, claiming that Mexican meat is contaminated.

    In 2012, Canadian weightlifter Nick Roberts received a two-year sanction after a urine sample tested positive for clenbuterol.


    Side effects and dangers

    Clenbuterol can cause following side effects:

    • Nervousness
    • Thyrotoxicosis
    • Tachycardia
    • Subaortic stenosis
    • Low blood pressure
    • High blood pressure



    Excessive use over the recommended dose of about 120 μg can cause muscle tremors, headache, dizziness and gastric irritation. Persons self-administering the drug for weight loss or to improve athletic performance have experienced nausea, vomiting, diaphoresis, palpitations, tachycardia and myocardial infarction. Use of the drug may be confirmed by detecting its presence in semen or urine.


    Food contamination

    In September 2006, over 330 people in Shanghai were reported to have gotten food poisoning by eating clenbuterol-contaminated pork that had been fed to the animals to keep the meat lean.

    In February 2009, at least 70 people in one Chinese province (Guangdong) suffered food poisoning after eating pig organs believed to contain clenbuterol residue. The victims complained of stomach aches and diarrhea after eating pig organs bought in local markets.

    In March 2011, China's Ministry of Agriculture (MOA) said that the government would launch a one-year crackdown on illegal additives in pig feed, after a subsidiary of Shuanghui Group, China's largest meat producer, was exposed for using clenbuterol-contaminated pork in its meat products. A total of 72 people in central Henan Province, where Shuanghui is based, were taken into police custody for allegedly producing, selling or using clenbuterol.


    Veterinary use

    The US and the European Union prohibit the use of clenbuterol in food-producing animals. It is, however, used in other parts of the world for the treatment of allergic respiratory disease in horses, as it is a bronchodilator. A common trade name is Ventipulmin. It can be used both orally and intravenously. It is also used in cattle to relax the uterus in cows, usually at the time of parturition. It is also a nonsteroidal anabolic and metabolism accelerator, through a mechanism not well understood. Its ability to increase the muscle-to-fat body ratio makes its illegal use in livestock popular to obtain leaner meats.
