A dietary supplement, GHR15 is one of the popular "growth hormone releasers" that have appeared on the market in recent years. Behind these products is the belief that increasing levels of human growth hormone in the blood will prevent or reverse age related changes in the body.
Human growth hormone, or hGH, is produced by the pituitary gland and plays an important role in growth in children and adolescents. Once full growth is achieved, at about age 21, the amount of the hormone produced drops off and continues to decline as the years pass. Experience with hormone replacement therapy in deficient individuals and athletes has suggested that raising levels in the blood can result in increases in muscle and strength along with decreases in body fat, and younger looking skin. Human growth hormone itself must be given by injection and is very expensive, factors that have instigated the development of growth hormone releases like GHR15.
Growth hormone releasers are required to stimulate the pituitary gland to release more hGH into the circulation, a natural alternative to hormone injections. These products are typically an amino acid package, containing a group of amino acids that are known to result in higher blood levels of growth hormone. In athletes, studies have shown that the amino acids arginine, ornithine, lysine, and tryptophan all have this effect, and growth hormone releasers like GHR15 typically contain some or all of these amino acids as well as others.
Growth hormone releases often also contain a beneficial of natural ingredients thought to augment the action of the amino acids. GHR15 contains anterior pituitary from cows, hypothalamus, ginseng, and a group of plant sterols and extracts used in natural healing and health. Some of these ingredients are thought to stimulate hGH release while the rest have other proposed health benefits.
The recommended dosage for GHR15 is four capsules daily (taken together) for five days, skip two days, then resume, repeated weekly for three months. Four tablets provide 1200mg of a blend of at least seven amino acids (glutamine, arginine, lysine, glysine, gamma-aminobutyric acid, pyroglutamate, tyrosine). This is actually a very small amount: one large egg provides well over 300mg each of glutamine, arginine, and lysine, and more than 200mg each of glysine and tyrosine, as well as 13 other amino acids for a total of more than 6000mg of amino acids. Similarly, half a cup of avocado provides more than 2200mg of mixed amino acids. While this suggests that supplementing with an hGH releaser is safe, it also suggests that the amino acids we need to maintain maximum production and release of growth hormone are readily available in a healthy diet.
Many testimonials report positive results from GHR15 and other growth hormone releasers. These products are readily available and quite inexpensive compared with hGH replacement injections. They are also likely to be safer (although individuals with a history of heart trouble are advised not to take products containing arginine). The pituitary gland releases maximum amounts of growth hormone during sleep and after exercise, so if you want to obtain maximum benefit from a growth hormone releaser, combine it with a healthy lifestyle including regular exercise, varied sources of dietary protein, and plenty of sleep.
