Why EAA adverse effects The presence of adverse effects is strongly related to the formation of metabolites produced during the transformations it undergoes in plasma testosterone. These transformations dominate the formation of dihydrotestosterone (DHT) and estrogens. The formation of DHT is known as reduction and in this reaction involves the enzyme called 5-alpha reductase metabolite responsible for benign prostatic hypertrophy, alopecia, acne and aggression training. The formation of estrogen is called aromatization and involves the enzyme called aromatase. This metabolite is responsible for producing gynecomastia, fluid retention, hypertension, lipogenesis and testicular atrophy (oligospermia). Other side effects: liver dysfunction, abnormal cholesterol levels, decreased immunoglobulins.The anabolic androgenic steroid, but not narcotic or psychotropic substances are consumed in many cases with a pattern of abuse in many sports, so that consumption of anabolic steroids for recreational, aesthetic or competitive, is considered by many psychiatrists as a drug, which produces short and long term health problems, physical and mental well in some cases, the type of psychosis. Anabolic steroids are synthetic substances related to male sex hormones (androgens). Cause skeletal muscle growth (anabolic effects), development of male sexual characteristics (androgenic effects) and also have some other effects. We use the term “anabolic steroid” here because of its familiarity, although the correct term for these compounds are steroids anabolic-androgenic steroids.Anabolic steroids were developed in the late 1930s primarily to treat hypogonadism, a condition in which the testes do not produce enough testosterone for growth, development and normal sexual functioning. The primary medical uses of these compounds are the treatment of delayed puberty, some types of impotence and body wasting caused by HIV infection or other diseases. During that decade, scientists discovered that anabolic steroids could facilitate the growth of skeletal muscle in laboratory animals, leading to the use of these compounds first by bodybuilders and weightlifters and then by athletes in other sports. The abuse of steroids has spread to such an extent in athletics that it affects the outcome of sporting events. Have developed more than 100 different anabolic steroids, but it requires a prescription to be used legally in the United States.Most come from steroids used illegally smuggled from other countries, are removed illegally from U.S. pharmacies or synthesized in clandestine laboratories. Most users are athletes who engage in high-performance, so it must rely on ergogenic aids that allow them to be at the highest levels of sport they are playing.
