I came across and interesting website which explained how L-Argenine & L-Glutamine can help increase HGH up to 400% when taken at certain times.
I'm going to cut a bit of the article, credit the author, an give the link as the articles run several pages.
Let me know what you think, and if anyone has tried this to boost HGH....

Arginine is an amino acid that is known as a growth hormone releaser. The decrease of growth hormone in the human body with aging is a major reason why muscle mass tends to decrease with age and body fat tends to increase with age. Decreases in growth hormone also are partially responsible for the slower rate of skin growth with aging, which results in thinner and less flexible skin. Injections of growth hormone can reverse these problems. Even though the cost of growth hormone injections have come down in price considerably in the past few years, they are still very costly. Growth hormone injections introduce growth hormone in a manner that is very different from the way it is produced by the pituitary gland. Growth hormone cannot be taken orally, because it is broken down in the digestive tract.
An alternative method of increasing one's level of growth hormone is to take a growth hormone releaser such as arginine. L-arginine, or L-arginine hydrochloride, taken on an empty stomach, will cause a significant release of growth hormone in many people. It is necessary, however, to use a very large dose of arginine: 10 to 30 grams, depending upon many factors such as one's age and body weight. Taking a few capsules of arginine will have no effect on growth hormone in adults. Arginine's growth hormone release is enhanced if supplemental choline and B5 (calcium pantothenate) are taken at the same time. The choline can be in the form of any available form of choline or DMAE supplement. (Centrophenoxine, a very safe substance available from European or Mexican pharmacies, can also be used as a choline source. Centrophenoxine is converted to choline in the body.)
Article #2 on HGH - Begin Paste:
There has been only one scientific study showing that L-glutamine causes HGH release, but there is a large body of anecdotal evidence from anti-aging physicians and their patients that L-glutamine is actually effective in persons under about age 45.
There is a large body of scientific study on the effects of L-arginine on growth hormone release. In fact, the administration of a large dose of L-arginine is the standard test for the ability of the pituitary to release growth hormone. (Another test using insulin is actually more effective, but it is not accepted as the standard test by the U.S. Food and Drug Administration.) Most scientists believe that L-arginine promotes HGH release by inhibiting somatostatin. L-arginine has many other benefits in addition to being a growth hormone releaser. See the chapter of this manual on Arginine for additional information about using arginine as a growth hormone releaser and for safety warnings about the use of arginine.
There are several problems with the use of amino acids as HGH releasers. Their effectiveness generally diminishes with age, and with continued use. This has led some people to the opinion that amino acids such as L-arginine are weak HGH releasers. This can be a dangerous assumption. In some young people, L-arginine may actually cause dangerously high levels of HGH release. Many young people use L-arginine, but it should not be used by anyone until at least 5 years after they have completed their long bone growth (unless they are under close medical supervision).
I personally know of one 19 year-old female who took L-arginine (about ten grams) before bedtime for one week. She stopped after one week because it was making her nauseous, which was an indication of an excessive level of HGH release. Even though she had not grown since she was 16, during the subsequent month, she grew an additional inch, and had a noticeable growth of her heel bones.
For most people, the doses of amino acids mentioned above (2 grams of L-glutamine and 10-30 grams of L-arginine) are about right for maintaining youthful levels of HGH beginning at about age 30, and continuing into the 40's, and sometimes (but very rarely) beyond 50. In order to maintain its effectiveness, these amino acids should be used for about 6 weeks, then stopped for 2 or 3 weeks. The same 6-week ON, 2 or 3 weeks OFF cycle can be continued indefinitely. This cycling helps to maintain the effectiveness of the HGH release.
Unfortunately, the effectiveness of HGH release with amino acids is highly variable from individual to individual. (I cannot emphasize this individual variability enough!) For some people, it is not a very effective means of HGH release for any long period of time. For a few (very few) others, it maintains its effectiveness until the age of 60 and beyond.
