A beta-2 adrenergic agonist. Prescribed as a bronchodilator for asthma in some countries and used in veterinary medicine as a tocolytic and bronchodilator. Significant cardiovascular side effect profile. Contamination of food supply is a documented false positive risk.
Clenbuterol is used in performance settings primarily as a thermogenic and muscle-sparing agent during cutting phases. The beta-2 adrenergic stimulation increases metabolic rate and promotes fat oxidation while the mild anabolic effect in skeletal muscle helps preserve lean tissue in a caloric deficit. Bodybuilders use it in the final weeks of cont...
Clenbuterol appears in contest prep stacks alongside T3 as the classic fat loss combination, where the beta-adrenergic stimulation of Clenbuterol and the metabolic acceleration of T3 produce additive effects on fat oxidation. This combination also creates additive cardiovascular stress and the combined risks are greater than either compound alone. ...
The cardiovascular side effects are not mild and they are not entirely reversible with chronic use. Tachycardia during use can be severe enough to be functionally limiting and genuinely uncomfortable. Cardiac hypertrophy with chronic use has been documented in animal studies and is a reasonable conc...
