The main reason for the high popularity of the growth hormone in sports is the ability to reduce body fat (http://sportwiki.co/index.php?title=HGH_Review._Forms_and_action_of_the_drug._Dosage,_Side_Effects,_Cycles&redirect=no). Some of the studies confirmed that HGH increases the lean body mass. GH is a stress hormone that raises the concentration of glucose and free fatty acids. It also stimulates production of IGF-1. (https://en.wikipedia.org/wiki/Growth_hormone). IGF-1 stimulates the growth of most internal organs.
