Never did GH so don't know on that, never went over 15 iu pre, I take 15 iu then take about 120g of dextrose with about 60g whey. Take power aid to the gym with me good whole way through no hypo. With 15 iu I have plenty of time to get home and have a full meal while it's still active. Now granted I'm more round the 5 hr area at 15 iu if I don't eat correctly then I can feel the hypo coming on. I go gym bout 830 and don't call myself safe till bout 130 cause I've felt the hypo come on before that late. Just my experience. Sorry at work so probably not the best spelling and wording.
