Its action is based on the stimulation of beta receptors, which results in increased body thermogenesis (a large part of calories is spent on maintaining increased body temperature), thanks to which it has excellent fat burning properties. Additionally, it stops the destructive effect of cortisol/cortisone on muscle tissue and increases protein synthesis, which results in a strong anti-catabolic effect even during calorie reduction. In addition, it increases the level of T3, which may have very good properties that enhance the catabolism of fat tissue. In combination with steroids, it works synergistically.

Salbutamol is a drug known since the 1960s and still widely used for asthma. It dilates the bronchi and increases muscle tension, so it is sometimes included in the "diet" of less honest athletes. There is an opinion that it is a steroid. Is not.
