CD, HGH is a prescription drug, so unless this website requires a script I wouldn't trust it. One of my buddies who' 46, is using 4iu's 5 days on 2 off and getting good results. He says he feels like a youngster, and I swear his skin looks alot better! If you can get legit HGH, it can be a great drug for people over the age of 35.
