Those who are in the world of body building or any competitive sports, clearly know the amount of pressure they bear to achieve optimal performance. Many athletes are of the view that without artificially enhancing powers they are unable to reach the peak value. Now in this article I am going to discuss the use of anabolic steroids, its working and its effects on human body.

• The main ingredient of steroid is testosterone; it is a well known major male hormone.
• Testosterone affects the body in two ways, as an anabolic and as an androgenic influence.
• The anabolic actions cause an increase in muscle mass and body tissues.
• The androgenic actions are those that affect secondary sex characters in males.

After careful study, many scientists provided us some the best facts about testosterone:

• Through muscle fiber hypotrophy, it increases muscle size.
• It causes an increase in cross sectional area of muscle fibers.
• 300 milligrams of testosterone are needed to bring the body at normal position.
• Muscle itself is directly affected by this hormone.
• It also has an anti catabolic effect.

From the above facts we can easily judge the importance of this hormone; one must use it in positive way to get better results. Due to illegal nature of steroid, body builders have to search for the scientific data to confirm or to have better knowledge about the steroids and supplements they are using.

It depends upon the tendency of body builders to use powerful steroids that led them to the dangerous condition.
