Direct effects are the results of binding between growth hormone receptors and target cells. One example of this is the effect of growth hormone binding with fat cells which results in the breaking down of triglyceride in fat cells and prevents them from taking and circulating lipids. On the other hand, indirect effects are brought about by Insulin like growth factor-I (IGF-I). This hormone is secreted as a response to growth hormone. It is also one of the primary aides of growth hormone in affecting growth.
HGH together with IGF-I have significant roles in different processes in the body. Examples of these processes are:
1.) Growth of all tissues including repair
2.) Turning body fat into muscle
3.) Energy level improvement
4.) Bone strength
5.) Brain function
The body actively produces growth hormones during childhood and puberty years. This active production results to height increase in individuals. However, at the end of puberty years, secretion of growth hormone decreases. It continuously decreases as people grow older. The decrease in the production of growth hormone contributes to weakness of bones in older people and their loss of strength. In some cases, children are born with growth hormone abnormalities. Growth hormone deficiency results in low stature of an individual. Excessive growth hormones result in having too much height.
Human growth hormone is very important in as much that is has become the subject of research. Researchers are continuously finding ways to use growth hormones in reversing aging and increasing muscle mass. Several researchers and companies have produced HGH products. These products are mainly used in treating HGH diseases. They are available in injections, pills and oral sprays. These HGH products and supplements are also being used in combating age.
HGH products are induced into the body to increase the HGH secretion therefore making the user feel young again. However, the fact remains that age can not be defeated and the aging process is inevitable for every human.
