Been on 5-8 iu's a day for a good yr. an half. Sometimes doing 10 iu from time to time. First got GREAT GAINS . Weight is staying steady maybe few lbs of water. Ok problem started when could NOT ejaculate during sex with my girl. Turns out SERATONIN level was extreamly HIGH . So started to lower down when I crashed . So now taking a Seratonin replacement . I guess that was the sense of well being , while on GH. Down to 2 iu's a day . My ejaculating is getting better. But the crash was VERY HARD. Can anyone relate to what I went through ? Have a specialist advising me. Said could tske up to 1 yr. before sex life is NORMSl .. Because could NOT keep my eyes open . I think I stayed on a little to long .. Thanks for any advice. If taken at 3 iu's a day . Think it's a GREAT supplement :banghead:
