In the human body growth hormone is produced by the pituitary gland. It exists at especially high levels during adolescence when it promotes the growth of tissues, protein deposition and the breakdown of subcutaneous fat stores. Upon maturation endogenous levels of GH decrease, but remain present in the body at a substantially lower level. In the body the actual structure of growth hormone is a sequence of 191 amino acids. Once scientists isolated this hormone, many became convinced it would exhibit exceptional therapeutic properties. It would be especially effective in cases of pituitary deficient dwarfism, the drug perhaps restoring much linear growth if administered during adolescence.
The 1980's brought about the first prepared drugs containing Human Growth Hormone. The content was taken from a biological origin, the hormone being extracted from the pituitary glands of human corpses then prepared as a medical injection. This production method was short lived however, since it was linked to the spread of a rare and fatal brain disease. Today virtually all forms of HGH are synthetically manufactured. The recombinant DNA process is very intricate; using transformed e-coli bacterial or mouse cell lines to genetically produce the hormone structure. It is highly unlikely you will ever cross the old biologically active item on the black market (such as Grorm), as all such products should now be discontinued. Here in the United States two distinctly structured compounds are being manufactured for the pharmaceutical market. The item Humatrope by Eli Lilly Labs has the correct 191 amino acid sequence while Genentech's Protropin has 192. This extra amino acid slightly increases the chance for developing an antibody reaction to the growth hormone. The 191 amino acid configuration is therefore considered more reliable, although the difference is not great. Protropin is still Anabolics 2002 considered an effective product and is prescribed regularly. Outside of the U.S., the vast majority of HGH in circulation will be the correct 191 amino acid sequence so this distinction is not a great a concern.
The use of growth hormone has been increasing in popularity among athletes, due of course to the numerous benefits associated with use. To begin with, GH stimulates growth in most body tissues, primarily due to increases in cell number rather than size. This includes skeletal muscle tissue, and with the exception of eyes and brain all other body organs. The transport of amino acids is also increased, as is the rate of protein synthesis. All of these effect are actually mediated by IGF-1 (insulin-like growth factor), a highly anabolic hormone produced in the liver and other tissues in response to growth hormone (peak levels of IGF-1 are noted approximately 20 hours after HGH administration). Growth hormone itself also stimulated triglyceride hydrolysis in adipose tissue, usually producing notable fat loss during treatment. GH also increases glucose output in the liver, and induces insulin resistance by blocking the activity of this hormone in target cells. A shift is seen where fats become a more primary source of fuel, further enhancing body fat loss.
Its growth promoting effect also seems to strengthen connective tissues, cartilage and tendons. This effect should reduce the susceptibility to injury (due to heavy weight training), and increase lifting ability (strength). HGH is also a safe drug for the "piss-test". Although its use is banned by athletic committees, there is no reliable detection method. This makes clear its attraction to (among others) professional bodybuilders, strength athletes and Olympic competitors, who are able to use this drug straight through a competition. There is talk however that a reliable test for the exogenous administration of growth hormone has been developed, and is close to being implemented. Until this happens, growth hormone will remain a highly sought after drug for the tested athlete.
The biggest mistake we can make with this drug is to get confused by the price tag. Even a relatively short cycle of this drug (and ancillaries) will cost in the thousand(s), not hundreds of dollars. We cannot jump to the conclusion that GH is therefore the most unbelievable anabolic. This hormone is simply very complex, and costly to manufacture In this arena, the money spent on it is well justified, the drug obviously necessary.
