Clenbuterol is used in the treatment of asthma, it causes the dilation of narrowed airways when an asthma attack occurs. Clenbuterol has actions similar to those of epinephrine and norepinephrine, chemicals that are produced in the body. These substances act before the body is preparing to undergo the action or stress, more air enters in the lungs because they contribute to airway dilation. This medicine is not recommended for those who have problems with their kidneys, liver, heart, and has diabetes.
Clenbuterol causes an increased metabolism, increases body temperature, and decreases appetite. That why many sportsmen use this medicine to lose weight and to preserve muscle mass.
Clenbuterol is sold in pills with a 20-40 mcg dose, and it should not exceed 200 mcg per day, which is still very high. Body temperature returns to normal after 8 weeks, therefore some use a thermometer to check their body temperature, if it is heating and when it returns to normal, after 8weeks discontinue administration and take a break because the body has adapted and clenbuterol is no longer effective.
