Introduction: Clenbuterol is a long-action adrenergic agonist that has several pharmacologic actions in humans. Clenbuterol in high doses can increase protein deposition and lipolysis similarly to anabolic steroids and is there by abused for bodybuilding and weight loss effects.

Aim: This systematic review aimed to summarize the existing scientific literature to understand the effects of clenbuterol on weight loss and muscle gain and consequently the possible side effects.

Methods: Literature review was conducted using the scientific data bases as Science Direct and Pubmed until April 2019, using search expressions “clenbuterol”, “side effects of clenbuterol”, “clenbuterol and weight loss” and “clenbuterol and bodybuilders”. The articles were select first by title and abstract and later it was made integral reading.

Results/Discussion: From the analysis of the studies described was found that beta-3 receptors are found on adipocytes and agonism has been shown to encourage lipolysis. Clenbuterol causes lipolysis and is noted to be a nutrient patitioning agente in skeletal muscle fiber, leading to increased muscle deposition.

Conclusion: Clenbuterol toxicity is clinically similar to toxicity from other beta adrenergic agonists and may result in nausea, vomiting, palpitions, thachycardia, hypotension, hyperglycemia, hypokalemia and a metabolic acidosis with increased lactate concentration. In addition, clenbuterol toxicity may be life threatening.
