Steroids in general include progesterone, estrogen and testosterone. These are originally present in the body. These are synthesized primarily by the ovaries and testes. Estrogen and progesterone are sometimes made in the placenta during the pregnancy period. However, steroids are further classified according to their functional and taxonomical origin. These includes: animal steroids, plant steroids and fungus steroids; each having their subclassifications. Animal steroids include insect steroids and vertebrate steroids. Vertebrate steroids are further classified into sex steroids, corticosteroids, and anabolic steroids. Anabolic steroids are considered to be the steroids in our modern language. These anabolic steroids are known for their ability to increase muscle mass and bone synthesis. Anabolic steroids are natural and can be synthetic. The discovery of this wonder substance initiated the history about steroid.
History about steroid dates back during the 1930s in Germany, when a scientist knew about the drug in a pharmaceutical form. During that time, no one took interest to discover its use. In the 1950s, methandrostenolone was introduced in the United States for its promising trials in other parts of the world. The use of the drug continued as it was approved by the FDA. In the 1960s to the 1980s, steroids were regarded to have doubtful effect. Little was known about its possible action. A study had shown that there was no considerable effect to those who took it and those who did not.
It was not only in the 1990s that when a thorough study was conducted about its use. In 1996, it was injected intramuscularly for 10 weeks. The results revealed there is indeed a noticeable effect for it to increase muscle mass and decrease fat among those who took the test.
It is not yet certain as to how the history about steroid will change its course in the future. During the past decades we have seen how it originated, evolved, and developed. Though steroids and other prohormones are now considered controlled substances, man will surely be able to modify its effect, its use, and mechanism of action. With all the advancement in technology, steroids will always be surely studied and be applied for the man’s benefit and advantage.
