Have you tried "that hgh spray"? It's hardly a scam, try it before you make your own set of false claims.
it's a scam because there is absolutely no science to back up such products that contain picogram doses of the active ingredients. you're likely to get more of the active ingredients of these sprays by riding your bike down the street with your mouth open.
and if you believe in homeopathy, it's a scam because it's a misuse of the concepts of homeopathy. True homeopathy is that the "esssence" of an element (which there is no such thing) counters that element. You would take the essence of arsenic (arsenic diluted in water so much so that there is less than one molecule per dose) to counter the effects of arsenic. So the "essence" of HGH should counter the effects of HGH, not enhance it.
if picograms of GH under the tounge is so effective, then why inject thousands or tens of thousands of time more? if less is more, why not inject 1 IU or 1/2 IU, or 1/10 IU rather than 18 that some bodybuilders do?
