Ive been reading on the forums and think I already know the answer to this question but I'll ask anyways for more info I've been on hgh for 3 months know I'm 18 and I went from 5 8.5 to 5 9 while on it when I started my sex drive was extremely high but for what ever reason I am know seeming to have premature ejaculation and softer erections it's ****ed up because usually I'd have sex around 1-2 times a week but now I haven't had sex for 2 weeks because of this problem I was reading a damaged thyroid can cause premature ejaculation as well as elevated prolactin levels anyways long story short any one else experience this ? Did it stop after you got off ?
