Steroids are a general term for a large class of cyclopenta-condensed fully hydrogenated phenanthrene derivatives widely distributed in the biological world. Also known as steroids and steroids. Steroid compounds do not contain bound fatty acids and are non-saponifiable lipids; these compounds belong to isoprenoid materials and are produced by cyclization of triterpenes followed by internal molecular reorganization and chemical modification. Steroids include steroids (eg cholesterol, lanosterol, sitosterol, stigmasterol, ergosterol), bile acids and bile alcohols, steroid hormones (eg adrenal corticosteroids, androgens, estrogen), insect ecdysone, Cardiac glycosides and saponins and toad poison. In addition, there are synthetic steroid drugs such as anti-inflammatory agents (hydroprednisone, dexamethasone), steroid drugs that promote protein synthesis, and oral contraceptives. 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 male hormone testosterone.
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 male hormone testosterone. Anabolic effects can increase skeletal muscle growth, and male sex hormones can make male sexual characteristics more obvious.
All synthetic androgen 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 androgenic effects.
In addition, it can speed up recovery after training, which helps increase training intensity and time. However, if the system’s strength training is not carried out at the same time, taking these drugs will have no effect on muscle growth.
Anabolic steroids were first used to treat hypogonadism in 1930 (the testes cannot produce enough testosterone to meet the needs of growth and sexual function). After that, it is mainly used to treat late puberty, impotence, etc.
In the 1930s, scientists found that anabolic steroids are beneficial to the growth of skeletal muscles in animal experiments. After that, bodybuilders and weightlifters began to take them, and finally developed into many sports.
