HGH Facts

Human growth is a very complex process, and requires the coordinated action of several hormones. The major role of HGH in stimulating body growth is to stimulate the liver and other tissues to secrete IGF-1* . IGF-1 stimulates proliferation of chondrocytes (cartilage cells), resulting in bone growth. IGF-1 also appears to be the key player in muscle growth. It stimulates both the differentiation and proliferation of myoblasts. It stimulates amino acid uptake and protein synthesis in muscle and other tissues. Increasing HGH triggers IGF-1, which brings about regeneration, repair and optimization within your body against the signs of aging.

HGH is a fast worker once it is released in the blood. Within 30 minutes or so it has done its job and is gone, just long enough to reach the liver. After reaching the liver, it is converted into IGF-1 and various metabolites that regulate and control metabolic response. IGF-1 is a hormone just like HGH, but it is easier to measure in the blood stream because it stays in the blood stream longer. HGH starts this conversion in the body, but IGF-1 is what does most of the work. In the body, these hormone-like proteins and peptides promote growth, nourishment, and repair of cells, which are needed to rebuild tissues damaged by injury, illness, or the effects of old age.

Another area of the brain called the hypothalamus (hypothalamus controls body temperature, hunger, and thirst) monitors the amount of HGH in the bloodstream. When the levels of HGH in the bloodstream reach the optimum level, the hypothalamus releases another hormone called somatostatin* , which tells the pituitary to cut back on the levels of HGH that it is releasing.

*IGF-1: insulin-like growth factor-1, also called somatomedin C, is another cell regeneration and repair signaling protein.

*Somatostatin is a hormone widely distributed throughout the body, especially in the hypothalamus and pancreas, that acts as an important regulator of endocrine and nervous system function by inhibiting the secretion of several other hormones such as HGH, insulin, and gastrin. It exerts its biologic actions by binding to specific high-affinity receptors on the cell surface.
