What is Clenbuterol?
Clenbuterol is a long-acting selective β₂-adrenergic receptor agonist with greater potency and duration than salbutamol. Studied for β₂-AR pharmacology, skeletal muscle anabolic effects (β₂-mediated mTOR activation), thermogenesis, lipolysis, and airway smooth muscle relaxation. Research use only.
