Clenbuterol is a powerful stimulant that increases metabolic rate and fat burning. Originally developed in the 1970’s to treat respiratory disorders in horses and other animals as well as nasal decongestant and asthma medication for humans. It acts as a bronchodilator, meaning that it relaxes the muscles around airways to make breathing easier.

Clenbuterol binds to the same receptors that respond to epinephrine (adrenaline) in your body, producing fat burning effects.

Furthermore, clenbuterol also binds to muscle cells and stimulates muscle protein synthesis, which is why it also helps you preserve muscle while cutting.

Both animal and human research has confirmed that clenbuterol raises metabolic rate and stimulates fat burning, and although it isn’t a steroid, studies show that it stimulates muscle protein synthesis, which will indeed help you retain lean mass while in a calorie deficit.
