Clenbuterol activates the sympathetic nervous system, stimulates beta-2-adrenergic receptors and causes lipolysis (fat burning). Clenbuterol has a significant ability to inhibit lipoprotein lipase activity, which makes fat accumulation almost impossible, and Clenbuterol increases the secretion of thyroid hormones, which also enhances the fat burning effects. Clenbuterol effectively protects muscle tissue from damage during drying. Clenbuterol has a moderate anabolic effect due to its anti-catabolic effect. Therefore, clenbuterol is mainly used in bodybuilding to cut and burn fat. For this purpose, bodybuilding uses clenbuterol in combination with ketotifen and thyroxine.
