Effects and dosage
Clenbuterol is a β2 agonist with some structural and pharmacological similarities to
epinephrine and
salbutamol, but its effects are more potent and longer-lasting as a stimulant and
thermogenic drug. It causes an increase in
aerobic capacity,
central nervous system stimulation, and an increase in
blood pressure and
oxygen transportation. It increases the rate at which body fat is metabolized while increasing the body's
BMR. It is commonly used for
smooth muscle-relaxant properties. This means it is a
bronchodilator and
tocolytic.
Clenbuterol is usually used in dosages from 20-60 micrograms (μg) a day when prescribed. A dose of about 20 μg (women) or 40 μg (men) should never be exceeded in a day.
Clenbuterol is also prescribed for treatment of
horses; however, equine use is usually the liquid form of clenbuterol.
