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.
Research Applications
β₂-AR Pharmacology
Long-acting β₂ agonism — receptor binding, cAMP elevation, desensitisation

Lipolysis Research
cAMP-driven triglyceride mobilisation, adipocyte β₂-AR signalling
Thermogenesis
Metabolic rate elevation, body temperature, uncoupling protein interaction
Airway Research
Smooth muscle β₂-AR relaxation, bronchoprotection, respiratory models
