Meltos (active agent – clenbuterol) is not an anabolic steroid, but rather a stimulant that belongs to a classification of compounds known as sympathomimetics. Clenbuterol’s original use as a medicine in the prescription drug market was (and still currently is) as a bronchodilator in the treatment of asthma. Upon activation of beta-2 receptors in the cell lining of the bronchial tubes, it initiates bronchial dilation (the opening and expanding of the airways) in the lungs, nose, and throat.
Clenbuterol is not an anabolic steroid, it does not express or exhibit any of the known side effects that are associated with anabolic steroid use. Instead, clenbuterol expresses side effects that are common to all drugs and compounds in the stimulant class.
