The human growth hormone is secreted natural in pituitary glands of human body and determines the growth of cells and their separation. The human growth hormone also determines the how proteins are released by growing cells. HGH will impact the usage of carbohydrates and fats by growing cells. All such features together prove that HGH will not affect the way of reducing fat and developing lean mass in the body.
The human growth hormone was first observed from pituitary glands of dead people under autopsy, but this HGH from dead people had some form of brain disease. Human growth hormone supplements can be helpful for children for whom natural secretion of HGH was inhibited and their bodies and brain disease began to grow up later. Human growth hormone is no longer observed from cadavers and some fake types of HGH also known as HCH are sold widely in black market. Though Human growth hormone is naturally secreted by pituitary glands, the amount of secretion might vary depending on diet and exercise we take. 
The amount is secreted in huge quantity particularly among growing children while adults develop less HGH as they are not required for natural growth of body. You can enhance the HGH levels in your body through use of supplements. The other side effects include carpal tunnel syndrome, thickening of bones and enlarged organs. People might also face side effects water retention and gynocomastia through the use of these HGH supplements.
