HGH (human growth hormone) is a hormone that is primarily responsible for the growth and development of your body. Growth hormone (GH) is a very important hormone that can influence your health in many ways. It is powerful enough to change the way you look, feel, and function.
What are hormones?
Hormones are substances formed in a type of body organ called a gland. A hormone is then directly carried in the blood circulation to another organ or tissue where it has a specific effect. In case of HGH, such gland is called as pituitary gland and it is situated inside your skull, just at the base of your brain.
HGH Mode of action
It stimulates the liver and other tissues to secrete insulin-like growth factor (IGF-1). IGF-1 stimulates production of cartilage cells, resulting in bone growth and also plays a key role in muscle growth. In children, this leads to growth in the length of the bones and increases the child's height. By puberty, however, the cartilage at the ends of most long bones is converted to bone and subsequent action of growth hormone or IGF-1 usually cannot increase their length. Therefore, as per medical evidence, taking HGH injections cannot increase your height after the age of 22 in majority of cases.
