Clenbuterol is a non-steroidal beta-2 agonist primarily used for its fat-burning and thermogenic effects, making it a favorite for cutting cycles. Often referred to as the “cousin” of ephedrine, it enhances metabolic activity and promotes fat loss. It is not an anabolic steroid but is widely used by physique athletes and competitive bodybuilders.
In medicine, Clenbuterol is used to treat asthma in some EU countries but is banned for human use in the U. S., where it is approved only for veterinary purposes.
