Anabolic steroids are the result from tests that are were made to produce a drug that has tissue-building ability that of the testosterone and at the same time separating it from testosterone's masculinizing properties. .
There are so many different kinds of people who use steroids; mainly they are athletes who want to compete, kids who are trying it for the first time and other school athletes, coaches in the GYM take steroids so they will look more muscular and huge from those who are training. On the other side, some people who perform hard work like policeman, fireman uses steroids to be more energetic. Models, dancers, and movie stars all of them take steroids for a better image (Yesalis, 5). Steroids have a medical use too. They help many patients who are going to make a surgery, for the elderly how want to regulate their hormones and many others use steroids to fight problems resulting from HIV and AIDS. But all these will not be our issue of discussion in this paper since we will concentrate on athletes" use of steroids (Yesalis, 6). .
There is one clear evidence that during hard training two things happen. First, the level of testosterone drops in the human body to the level of the castrated one. The other thing is that body release glucocrticoids which break down tissue, catabolic effect. We conclude that over training may cause muscle decrease. As a result the importance of steroids use while training is increasing. Steroids help in increasing protein syntheses through its interaction with the targeted tissue. So after the DNA in the cell, chromosome, interact with the anabolic steroids that have reached through the blood, various enzyme, structural and contractile proteins formation take place. This helps muscles to grow faster (Yesalis, 27-29). .
The other thing is Placebo Effect; it is the physical or the psychological change that results from taking an inert substance, believing that this inert will have a therapeutic effect.
