I am 19 and a half years old and want a bigger cock. I have done lots of research involving HGH and penis size...it supposedly increases girth dramatically in some individuals. Now I want to know has anybody under the age of 25 used HGH and noticed a size increase?? I think that being younger will give you and advantage, I plan on taking 2 ius for the first few weeks and then upping to 4ius for 5-6 months total. I have been lifting for a couple years and im 190 with 10% bodyfat, so I'm not some fat loser trying to just get a bigger cock lol...please share your experiences!! Thanks.
