Amino Acids: GH Releasers
Arginine – This amino acid has been proven to release growth hormone in exercise trained men, which means that chronic use has some very good data behind it to show GH releasing properties. It works by blocking the hormones that reduce production.
Glutamine – This has also been shown in studies to increase growth hormone release in exercise-trained individuals and makes a very good amino acid to add to any GH releasing supplement. It’s best taken at night to help release growth hormone.
Lysine – This amino acid has been shown to potentiate the effects of the other amino acids for GH release and is good to add to blended GH secretagogs.
Arginine Pyroglutamate – Arginine has already been shown to increase growth hormone as does Glutamine and this supplement combines both into one peptide. This is simply Arginine bound to a cyclic glutamine peptide and it has been shown to have a better effect on GH than either arginine or glutamine alone.
Ornithine AKG – University studies have shown that Ornithine increases both insulin and growth hormone levels, which are needed to build and maintain muscle during intensive physical training. So, Ornithine has some serious beneficial effects for the bodybuilder. As the body ages, Ornithine may also help combat the muscle loss that is a normal part of the aging process. By helping to elevate growth hormone levels, Ornithine may help speed the production of muscle tissue and offset the effects of aging, which is of obvious benefit to the bodybuilder.
L-Tryptophan – This amino acid is back on sale in the U.S., thankfully, because it makes for one heck of a GH releasing product. Unfortunately, doses of 3-5g are necessary to achieve a positive GH response, making it a killer product to stack, but impossible to take in a combination supplement.
