The Human Growth Hormone or the HGH is naturally produced by the human body in the pituitary gland. This hormone promotes cell growth and body metabolism to a large extent. The production of HGH is high during adolescence; however, it tends to decline after the age of 30. Today Human Growth Hormone supplements are available in different forms to stimulate the growth of the human body. Although HGH supplement intake has been questioned for the past several years, the growing usage and effectiveness can be attributed to its widespread popularity.
