Ephedrine is a substance used by athletes to lose weight. It promotes the secretion of norepinephrine, which is similar to adrenaline, which in turn acts on alpha and beta receptors. Ephedrine increases the activity of the central nervous system, this after raising body temperature, which will stimulate the metabolism. This will help burn the fat layer. The anabolic effect of steroids can be enhanced with this substance, the metabolic rate being measured during the conversion of lipids, carbohydrates and fats by the body. Many athletes use 50mg before training to be better stimulated and workouts to have a higher yield. It is important that ephedrine is not used for a long time, because the body will get used to it.
