I'm not sure how wise something like this might be.. but if your short I can certainly see how attractive the Idea might be. I certainly wouldn' recommend actual growth to a growing boy... if you were lacking natural HGH, that is something the doctor could prescribe.. otherwise your messing with your health pretty seriously.
As far as boosters go... I don't think that's a great idea either. but then again, perhaps it's not a terrible thing. I can't say either way. But what I can say is there is alot of crap products out there that will do nothing for you.
I've been hearing really good things about a product called P-GH. (wonders if should of mentioned this.).
