What is Clenbuterol?
Clenbuterol is a selective beta-2 adrenergic receptor agonist activating β2-AR in bronchial smooth muscle (bronchodilation), adipose tissue (lipolysis/thermogenesis via cAMP/HSL), and skeletal muscle (anti-catabolic via β2-AR/cAMP/PKA → protein synthesis, reduced proteolysis). CAS 21898-19-1.
Research Applications
