Growth hormone (HGH) is a protein secreted by adenohypophysis cells and is a peptide hormone. The growth hormone produced by recombinant DNA technology is referred to as r-HGH. Under normal circumstances, growth hormone HGH was pulsed secretion, growth hormone (hGH) secretion by the hypothalamus produced by the growth hormone releasing hormone (GHRH) and growth hormone inhibition hormone (GHIH, also known as somatostatin SS) regulation, also By sex, age and circadian rhythm of the impact of sleep secretion significantly increased. The main physiological function of growth hormone is to promote the growth of all other tissues outside the nerve tissue; promote the body’s metabolism and protein synthesis; promote lipolysis; antagonize the role of insulin; inhibit the use of glucose to make blood sugar and so on. Serum growth hormone determination contributes to the diagnosis of growth hormone deficiency caused by giant disease, acromegaly and hereditary growth hormone deficiency.
The human growth hormone is a natural protein hormone secreted by the pituitary gland. In the past, there was only one way to secret HGH: through human bodies. Human growth processes along with cell regeneration and reproduction of the human body growth is usually dependent on the HGH or human hormones. It is commonly used as growth hormones for children with growth disorders and also treats diseases, but over the last years, HGH has been touted specifically as a powerful means for the treatment of obesity and the aging process.
With age, this hormone decline by around 14% per decade. You should start noticing the reduction when you get to age 30. The reduction of HGH could be as a result of changing external conditions, inability to get adequate rest or sleep, aging, stress and high blood sugar among others
Since the late of 1980s, recombinant human rHGH is made and with good results in the treatment of patients suffering from a deficiency of this hormone. However, because of its anabolic properties, it was an abuse in the sport world. Athletes and body-builders felt that human hormones increase lean body mass and reduce fat mass. The use of HGH as anabolic steroid by experienced athletes has been for a long time been the subject of controversy, and is currently banned, yet it is only recently, that blood tests can establish between synthetic HGH release and that of the body
