Insulin is a highly anabolic and powerful hormone produced by all human beings and is essential to a well-functioning individual. Although produced naturally by the human body, insulin is often administered exogenously to those suffering from diabetes. Some performance athletes also use it in an effort to grow lean tissue. However, off-label use can be very dangerous; extreme caution is advised.
