Human Growth Hormone: Human Gh
built 655 days ago
Growth hormone (GH) acts by interacting with specific receptors on the surface of the cells. Increase in height is one of the best known effects of growth hormone (GH) actions in children and it is stimulated by two mechanisms.

The pituitary releases GH when it receives a signal from the brain's hypothalamus in the form of growth hormone releasing hormone (GHRH). Release... can also be triggered by stress, exercise, emotional excitement, fasting, sleep, or hypoglycemia (low blood sugar). Release is inhibited by the hormone somatostatin and may be inhibited by lack of sleep, high blood sugar (hyperglycemia), obesity, a high blood level of free fatty acids, and by growth hormone itself. American endocrinologist Roger Guillemin and colleagues isolated somatostatin in 1973 and growth hormone releasing hormone (at that time called growth hormone releasing factor; now known to be a hormone) in 1984.
(The information here on growth hormone releasing hormone (GHRH) will only be of academic interest to most people. Many people may want to skip over this section. If you can't get real injectable HGH, though, the injectable GHRH product may be a reasonable option.)
The effects of growth hormone deficiency vary depending on the age at which they occur. In children, growth failure and short stature are the major manifestations of GH deficiency. It can ... cause sexual immaturity. In adults the effects of deficiency are more subtle, and may include deficiencies of strength, energy, and bone mass, as well as increased cardiovascular risk.
Despite its name, growth hormone does not directly promote growth; rather, it acts by stimulating hepatic generation of somatomedin C (insulin-like growth factor-1 or IGF-1), one of many growth factors. The plasma level of GH is regulated principally by the opposing effects of two neuropeptides that are produced in the hypothalamus and reach the pituitary by the portal circulation:
