Human Growth Hormone Human growth hormone is a chemical formula that prevents biological aging. For most people, the only thing known that has the same effect as HGH is "the fountain of youth". HGH is one of the many endocrine hormones present in the human anotomy, such as estrogen, progestoren, testosterone, melatonin and DHEA, whose production decreases with age. Many of these hormones can be replaced to discourage some of the effects of aging. HGH is far superior to any other hormone because it not only prevents aging but also reverses most of the signs and symptoms associated with aging. HGH, also known as somatotropin, is considered one of the most abundant hormones secreted by the pituitary gland. Somatotropin is produced at a rate that is most significant during adolescence, when accelerated growth occurs. As we age, the amount of HGH produced decreases significantly. Human growth hormone was primarily used to treat patients with growth hormone insufficiency due to limited availability. With the advent of new developments, HGH can be used to treat other symptoms such as Turner syndrome. Turner syndrome is a genetic defect linked to short stature. TS affects only women and is caused by a defect in one of the X chromozones. Growth hormone is also used for growth hormone deficiency in adults, caused by the onset of growth hormone insufficiency during childhood. Growth hormone secretions regulate a number of metabolic processes in adults. The only disadvantage of HGH injections is that the long-term effects are unknown. Some of the effects of somatotropin are most noticeable on cartilage and bone cells. If your body continues to produce growth hormone after the cartilaginous plates fuse, other bones respond such as your jaw, forehead, toes, and fingers.
