Clenbuterol (Cat.No:I024900) is a selective β2-adrenergic receptor agonist commonly used as a bronchodilator for the treatment of asthma and other respiratory conditions. It has also gained popularity as a performance-enhancing drug due to its ability to stimulate fat burning and promote lean muscle growth. However, clenbuterol is banned in many sports organizations due to its potential misuse and adverse effects on cardiovascular health.
