My experience is that I load up with 1ml bacter water in my GH vial and take 10iu in morn at 6am and another 10iu at 11pm at night for 5 days then take 5 days off and repeat, my gains where incredible with no tiredness at all.. Works very well in conjunction with Test, tren etc.. Just my experiences, it actually took me into the 300 club...
