Clenbuterol or Clen is a β2 agonist that is used as both bronchodilator and tocolytic. It is extremely useful in offering comfort to individuals affected with wellness issues such as bronchial asthma, respiration conditions, hypertension, and anaphylactic shock.  The medication has also been popular as a weight-loss and efficiency improving medication that does not lead to adverse reactions that are generally associated with the use of other performance enhancing drugs (especially aromatizable and severe steroids), unless the purchased Clen is of low quality or misused.

It is important to note here that some of the most successful sportsmen on the globe of professional activities have used (or considered to have used) Clen in the past and the list of such sportsmen includes American swimmer Jessica Hardy, Cyclist Alberto Contador of Spain, Polish sprint canoer Adam Seroczyński, Chinese cyclist Li Fuyu, and St. Louis Cardinals minor league shortstop Lainer Bueno besides 109 football players from the Under 17 World Cup 2011 in South America who tested positive for Clenbuterol.

In order to obtain its benefits, Clenbuterol users may stack it during a steroid cycle of 6 to 8 weeks with legal anabolic steroids such as EPO, Dianabol, T3 Cytomel, Deca Durabolin, Anavar, and Winstrol. It is suggested that users of this medication consumes at least 7-9 glasses of water per day and take 200 to 400 mg of potassium supplements every day or T3 Cytomel (12.5-25.0 mcg per day) so that occurrences of muscular pain can be decreased or removed. As far the diet is worried, it should consist of low fat (0.25g per lb of bodyweight), high protein (1.5g per lb of bodyweight), and moderate carbohydrates (0.5g to 1g per lb of bodyweight).

The best dosage of Clenbuterol is 100 to 140 mcg per day for men and 80 to 100 mcg per day for females (preferably in a 2 day on and 2 day off cycle or a three weeks on and three several weeks off regime), and these dosages can be taken without any meal planning. The use of this weight loss drug is, however, not suggested instantly before extreme exercises and the medication should not be used by breasts feeding or expectant mothers or those hypersensitive to its ingredients or experiencing wellness issues, such as breasts cancers, prostate cancers, testicular cancers, high blood pressure, stroke, and kidney damage.
