Human growth hormone, which is usually known as HGH, is nothing but a natural hormone which is produced in the body of all human beings. It is made in the pituitary glands of the human brain and in the master glands of our body which are located in our endocrine system. These hormones are similar to estrogen and even testosterone.

HGH stimulates development in a child and does play a vital role in an adult’s metabolism. In any human, the level of the growth hormone reduces by about 15% per every ten years after a particular age. HGH deficiency exists only when these hormones are absent or not produced in an adequate amount. It has to be in the right quantity, or it can cause various problems.
For a long time, scientists thought that HGH had a very vital role but only by the age of puberty. That means it wasn’t a part in growth and wasn’t used at all by the human body.

However recent studies have revealed that HGH is a part of a lot of physiological processes all through the life, and also is involved in the turnover of muscles, bones and collagen.
