Clenbuterol is a slightly thermogenic compound. This means that it slightly raises the body temperature of the person taking it. When the body's temperature rises it burns fat more productively. Clenbuterol is especially effective and is the substance of choice for many bodybuilders and people in general who are looking to loose weight fast. At a dosage of around 5-7 tablets or 100-140 mcg per day for men, and for women 80-100 mcg per day, over a period of 8-10 weeks, Clenbuterol will effectively burn fat with minimal side effects (all of which are temporary). Many people have reported extreme weight-loss from Clenbuterol, especially when combined with another fat-burning product like Triac or Ephedrine.
