1 box contains 50 tabs.Each tab contains 20mg clebuterol hydrochloride.Clenbuterol is a very interesting and remarkable compound. It is not a steroid hormone but a beta-2- symphatomimetic. Clenbuterol, above all, has a strong anticatabolic effect, which means it decreases the rate at which protein is reduced in the muscle cell, consequently causing an enlargement of muscle cells. For this reason, numerous athletes use Clenbuterol after steroid treatment to balance the resulting catabolic phase and thus obtain maximum strength and muscle mass.A further aspect of Clenbuterol is its distinct fat-burning effect. Clenbuterol burns fat without dieting because it increases the body temperature slightly, forcing the body to burn fat for this process. Due to the higher body temperature Clenbuterol magnifies the effect of anabolic/androgenic steroids taken simultaneously, since the protein processing is increased.
