15-18 iu a day?? You guys kill me. The cost for serono saizen is $300 for 10 iu in Canada, and I also know several high-level bodybuilders who DO NOT go above 5iu's!!!!! Look, do you think "generic chinese" gh is the same as doctor prescribed?? nope.Unless a bodybuilder was a wealthy millionaire, he couldnt afford real gh at even 10 iu a day. I am personally taking doctor prescibed saizen and feel way better, skin, sleep, fat loss, and am running a minimum dosage.Thats like saying you need 2000mg of test a week to get big, once again, wrong.
