These two very similarly named items may be easy to confuse, but there are vast differences between them that I will explain below. While Clenbuterol is not actually a steroid, its powerful fat burning capabilities are highly prized by some anabolic steroid users. Clenbuterol is a stimulant and a prescription bronchodilator used in the care of asthma patients. CCUT, on the other hand, is a legal and natural alternative to Clenbuterol created by Brutal Force with the intention of producing the same results without side effects.
