There are many users of prescription HGH formulas as the reasons for undergoing hormone therapy is wide and varied. The most common use of prescription HGH, especially when it was first launched, almost two decades ago, was for the treatment of conditions in children, such as stunted growth, to help reduce excess body fat and encourage weight loss (treatment of obesity, whatever the cause) and for reversing the signs of early aging due to the reduced production of naturally occurring HGH.
