1.  Another name for growth hormone is somatotropin, which is produced in animals, or somatropin, which is produced in human.
2.  GH has many important effects include decreased body fat, increased muscle mass, increased bone density, increased energy levels, improved skin tone and texture, increased sexual function, and improved immune system function.
3.  Peptides released by hypothalamus (GH- releasing hormone and GH- inhibiting hormone) are mainly responsible for GH secretion.
4.  GH secretion is considered as a negative feedback mechanism. The GH – releasing hormone stimulates (GHRH) the release of GH. When the GH levels in blood go too high, the GH – inhibiting hormone (GHIH) reduces the release of GH.
5.  Growth hormone is used in medicine to treat children's growth disorders and adult growth hormone deficiency. In recent years, growth hormone replacement therapies have become popular in the battle against ageing and obesity.
6.  The illegal use of GH in a sport event can change the result in a negative way. Athletes, who use GH, can easy win over one or two events but using too much GH causes their body aged faster. GH can bring an athlete to the top of his career but after that it will destroy every single cell in his body. The life shortened is not what every athlete is willing to do and because using too much GH is really dangerous so that is why they banned it.
