Growth hormone or somatotropin is a protein based peptide hormone which is synthesized and secreted by cells of anterior pituitary, called somatotrophs. It controls several complex physiological processes such as growth, cell reproduction, metabolism, and regeneration in human body and animals. It is also considered as a drug that is helpful to humans.
Growth hormone is termed as somatotropin when it is produced naturally by animals. On the other hand the term somatropin or HGH refers to the growth hormone produced by recombinant DNA technology. HCG is used in the manufacturing of medicines that helps to combat the childrens growth disorders and adult growth hormone deficiency.
In last few years, the growth hormone replacement therapies have become the popular way to cure obesity and aging. Studies shows that a person, who is undergoes six month program of HGH, have successfully reduced their body fat by 14.4%. Also there has been an increase in the lean muscle mass by 8.8%.
Growth hormone starts to decline in human body, as they grow old. It declines up to 25% in every ten years, after the age of 30 so when you reach 60, you are left with only 25% of the original capacity.
Pattern of Secretion of GH:
Growth hormone is synthesized and secreted from the anterior pituitary gland, throughout the day. Process of secretion repeats at every 3-5 hour intervals. Largest production of this hormone occurs about an hour after your sleep.
However this level varies according to the individual and season. Some of the common factors which affect the HGH secretion are age, gender, exercise, stress, diet and other hormones.
Benefits of Growth Hormone:
Growth hormone was discovered in the 1920s and was isolated in the form of somatotropin in 1956. The effects of GH on our body system are:
- Improves the quality and duration of heart and kidneys
- HGH produces more energy
- Builds stronger bones
- Improves sexual performance
- Promotes and increase the synthesis of new protein tissues
- Improves the sleeping pattern
- Enhance metabolism of body fat and convert this to energy source
- Increases height in children and adolescent
- Increases calcium retention of bones
- Promotes lipolysis
- Plays a role in homeostasis
- Maintains the functions of pancreatic ducts
Who needs to take GH?
Synthetic growth hormone is injected after prescription, to treat the adults who have deficiency in hormonal growth. In adults the deficiency of growth hormone is rare and caused by pituitary adenoma, a tumor on the pituitary gland. It is treated by surgery or radiotherapy.
Injection of growth hormone in adults can increase the bone density, decrease the body fat, increases muscle mass, and exercise capacity. It is also approved to treat AIDS or HIV- related muscle wasting.
There are some websites which are selling the HGC in pills and they claim that they produce the same results which are produced through injecting it in the form of drug. These dietary supplements are called human growth hormones releasers.
There are many people who believe that making growth hormone legal and authorizing hormone replacement therapy would be great advantages to the health care system. There is no doubt that the HCG is targeted to meet the demands of the bodybuilders.
