Anabolic steroids are similar to synthetic male sex hormones. They are a class of chemically synthesized derivatives similar in structure and activity to the human androgen testosterone. The role of anabolism can increase the growth of skeletal muscle, and the role of male sex hormones can make male sexual characteristics more obvious. All synthetic androgenic steroids have a chemical structure similar to testosterone. In addition to the effect of increasing muscle mass and strength, and maintaining muscle volume during active or passive weight loss, these drugs also have an androgenic effect. In addition, it can speed up recovery after training, which helps to increase training intensity and time. However, if the system is not trained at the same time, taking these drugs will not increase the muscles.
Anabolic steroids were first used in 1930 to treat hypogonadism (there is not enough testosterone in the testes to meet the needs of growth and sexual function). After that, it is mainly used to treat late adolescence, impotence and so on.
In the 1930s, scientists discovered that anabolic steroids were beneficial to the growth of skeletal muscle in animal realization. After that, bodybuilders and weightlifters began to take it, and finally developed into a lot of sports and began to take anabolic steroids. Today, steroids are widely used in sports, which seriously affects the outcome and fairness of sports competitions.
To date, more than 100 anabolic steroids have been developed in the United States, most of which are illegal, some are smuggled into the United States, and some are developed or produced by some pharmaceutical companies or secret laboratories.
