Are body building steroids safe?

 
The body secretes steroid hormones in order to maintain several normal functions. The amount of steroid secreted is controlled very delicately, mainly by assessment of the concentration of steroid hormone present in blood. Body building steroids cause an increase in the concentration of steroids in blood. This will suppress the secretion of the normal hormones by your body. Over time, the organ systems in the body that secrete these hormones can stop functioning normally. Further, when you stop taking the hormones, your body may not be able to recover normal functioning of the steroid hormone system. So, taking external steroids whether for body building or as medication can have severe side effects. Steroids should _never_ be taken without medical prescription and supervision.
