A good read about HGH and derivatives
The article above should give the reader a good insight of how, where and what to expect of HGH, also there is very interesting feedback on studies done in over 40,000 patients with HGH replacement therapy with no negative feedback (Pfizer) and cost per UI in the US
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 early 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.
The one way to enhance your HGH levels regardless of age, or other factors, is to use injectable HGH. For most people past the age of 40 years or so, (until tesamorelin becomes available) this is the only HGH option that will really work well. The use of injectable HGH has been a subject shrouded in mystery for most people. The rest of this chapter will describe some of the details about what using injectable HGH is really like
This plus a good read of:
The HGH Protocol post by BBB
The HGH Experiment by Cortez,
Should give the reader enough information about hgh and its uses
