What are Steroids?
Until the year 1935 scientists never knew that testosterone steroids were associated with an increase in muscle production. During the next two years scientists found through research with dogs that in certain circumstances steroids had an increase on muscle mass production. There are three major divisions of steroids: corticosteroids, estrogens and progestogens, androgens. Corticosteroids are found in both prescription and non-prescription creams that are used to control rashes and itches. These two common trade names are Cortaid and Lanacort. This form of steroid is not to be thought of as having addictive properties. The second forms of steroids are estrogens and progestogens. These forms of steroids are female sex hormones that promote sexual development and help to maintain a healthy reproductive system. The third forms of steroids are androgens. These are the male hormones called testosterone, which lead to secondary sexual characteristics and also help to maintain the male reproductive system. These specific forms have been labeled a highly addictive and are frequently abused; they are referred to as “anabolic steroids.”

How Are Steroids Used
There are two ways for anabolic steroids to be taken into the body, both orally and injected. Oral steroids are highly potent and are excreted fairly rapidly from the body due to short metabolic half-lives (usually within weeks). So, oral steroids are the first choice from athletes who want to rapidly improve their performance and try to escape from the drug tests. Unhappily, these drugs are the most toxic and which have more side effects. Injecting a steroid is less potent and generally exhibits delayed uptake into the body, especially if they are oil-based dilettantes. They have less liver toxicity than oral steroids, but athletes, in having detectability in drug tests for long periods make them less attractive.

Effects of Steroid Use
It has become apparent that anabolic/androgenic steroid usage has negative effects on the following systems of the body: liver and cardiovascular, central nervous, musculoskeletal, endocrine, and reproductive systems. The chart below shows each of the side effects in respect to the system that is affected. It also indicates whether the effects are permanent or just temporary.
