What is the human growth hormone?

Human growth hormone, also referred to as HGH, is released by the pituitary gland – which is a pea-sized gland found behind the bridge of the nose. Human growth hormones play an important role in promoting growth in children. However, human growth hormone levels begin declining when a person reaches the age of around 30, followed by declining by a factor of 2 or 3 when the person is around 40 years of age. In a nutshell, HGH levels continually decline with age.
