There is no cheap alternative to recombinant HGH for injection. All oral products don't work as good and are mostly a money making scheme. Even high dose Arginine, Ornithine etc. are limited in the effects of increasing GH/IGF-1 even though they might prove effective for non-severe GH deficiency.
@amaru7, your are misleading people when you say that there is no cheap alternative to recombinant HGH injections. As mentioned earlier, the peptide injections used by body builders, such as CJC-1295, GHRP-2, GHRP-6, ipamorelin and hexarelin, work well to increase HGH.
This study for example found that the peptide CJC-1295 worked perfectly well as a HGH substitute. And in fact CJC-1295 was more convenient, as unlike HGH, it only needed to be injected once a day for normalization of growth in the mice.
This article compares HGH injections with HGH stimulating peptides, and finds a number of significant advantages of the peptides over HGH.
Certainly there are many oral HGH products out there, like "homeopathic HGH" and the like, that do nothing, and are cons, and purely sold as a money making scam.
And yes, taking high doses of HGH secretagogues such as arginine, ornithine, alpha GPC, creatine, glutamine, etc only has a very limited and weak effect in raising HGH.
But injectable HGH stimulating peptides work, and are a cheaper, easier to obtain and a safer alternative to HGH.
