Clenbuterol
Clenbuterol is a long-acting beta-2 adrenergic agonist (a bronchodilator and livestock 'repartitioning' agent) used off-label for fat loss — never FDA-approved for humans, banned in sport as an anabolic agent, and notable for serious cardiac and electrolyte toxicity. It is not a steroid and not a peptide.
