A 1981 study by researchers from the Medical Clinic V. University of Rome, Rome, Italy showed a surprisingly good response in HGH release from oral administration of argynine pyroglutamate in combination with lysine in really tiny amounts.
Arginine pyroglutamate has the ability to pass the brain barrier, that's probably why is so effective in such small amounts and why causes such a remarkable effect on HGH release.
All other forms of arginine don't do that and the effect on HGH is after all negligible or even negative, therefore arginine pyroglutamate is in a class of its own.

Fifteen healthy male subjects, aged 15 to 20 years old, were given 1,200 mg of arginine pyroglutamate combined with 1,200 mg of L-lysine hydrochloride.
The results of this specific combination were spectacular, causing a large GH release that was sustained for several hours.
This breakthrough paper has often been misquoted and discounted, as several other researchers failed to replicate the results.
Unfortunately, these subsequent researchers used arginine hydrochloride and NOT arginine pyroglutamate, which was used with great results in the original study in 1981.
This is disappointing, as it had been known since 1977 that the specific chelate of arginine and pyroglutamic acid (arginine pyroglutamate) had effects on the body that are not shared by arginine or pyroglutamic acid when taken individually or together.
No nutritional supplement has shown equivalent results to the combination of arginine pyroglutamate and lysine for releasing significant amounts of biologically active GH when taken orally in small doses.
Interestingly, when both arginine pyroglutamate and lysine are taken individually, even in large doses, they are not effective.16 It is the specific combination of arginine pyroglutamate and lysine, taken in the proper ratio, which makes a very effective GH releaser.

Unfortunately it seems that here in Europe arginine pyroglutamate is rare to find and largely overpriced, if anybody knows a reliable seller with reasonable prices the information will be warmly welcome.
It may well be one of the cheapest and safest ways of increasing the release of HGH (in USA 500gr of arginine pyroglutamate, roughly enough for 1 year, goes for about 35$ and lysine is even cheaper).
Probably overlooked because too simple and not patentable...:(
Any direct experiences with this HGH booster?
