injectible HGH good, oral HGH bad...
Used orally, rHGH is useless to bodybuilders. Orally administered GH has very poor bioavailability (absorption). The reason it doesn't work orally is that it's "digested," much like most protein supplements or even a piece of chicken, into smaller and smaller proteins. RHGH converts into single amino acids as well as tripeptides and dipeptides due to the digestive process. The body can absorb these smaller peptides (and not intact rHGH) just the same as any other amino acid or small protein molecule. It is claimed that GH is significantly absorbed from the oral mucosa if delivered by spray. The rHGH molecule is far too large to be effectively absorbed sublingually or transdermally. Given orally, rHGH can be considered an expensive amino acid supplement. While there are anecdotal reports of the homeopathic sprays and orals working for some, there is no credible evidence that oral or spray HGH has any health benefit.
