Clenbuterol is a beta-2-agonist. Beta-2-agonists are used to treat asthma. It dilates the airways, which narrows during an asthma attack. It works by copying the effects of natural substances such as adrenaline and noradrenaline, substances produced in the human body. These substances prepare the body for action, such as exercise or when subjected to stress. One of the effects of these substances is to open the airways so that more air can reach the lungs. They should not be used when you have severe kidney and liver problems and should be used with great care when you have heart and circulation problems, thyroid gland, diabetes.
Clenbuterol acts selectively on beta-2 receptors. When they act on them, there is an increase in body temperature, an increase in the rate of metabolism and a decrease in appetite. Because of this, clenbuterol is used by many athletes to lose weight without losing muscle mass. In addition to the thermogenic effect, clenbuterol also has an anticatabolic effect.
Clenbuterol comes in tablets of 20 or 40 mcg, but is also available in the form of syrup, inhalation pump, injectable, powder and granules. Doses are highly dependent on how the user responds to side effects, but are in the area of 40-120 mcg / day. It should never exceed 200 mcg / day, which is a lot anyway.
Clenbuterol loses its thermogenic effect after 8 weeks, when the body temperature returns to normal. That's why most athletes who use it use a thermometer to check their body temperature. Clenbuterol increases it a little, and when the temperature returns to normal the administration should be interrupted and paused because the body has adapted and Clenbuterol is no longer effective.
