When I first started GH several years ago and still taking to this day I started at 8iu Ed,,, I ran that for 2 months and again this is when GH was dirt cheap. I started doing some more research and discovered from a pro BB that best results come from a M-W-F stick. The results I was getting from ED @ 8IU was great but money was in issue so I took a cheaper path. I'd say I started GH when I was about 37 years old I weighed around 205 at 5'9" tall and 16% bf of course I was using with gear and would use when I came off my cycle also. Results was good at 8 iu but was not getting lean part was because my diet. When I switched to the 5iu m-w-f an tightened up on my diet after after about a year plus and switched my workout up,,,, shit went crazy. I dieted hard for 2 months, my workout was a M-W-F lift 1.5 hours and NO cardio at all, this was at a private studio so no waiting for equipment to free up. Monday lift was chest/shoulders/tri,,,, wed was legs/calfs,,,, Friday was back/bi's. My body fat dropped 4% in a period of just 2 months with a strict diet and the definition was crazy, shit was popping out everywhere, I was getting shredded fast. My weight dropped just a little so I went off my diet only eating about 1 healthy meal a day, the rest was double bacon burgers and coke to drink. My body fat continued to drop still and ended up about 7-8% still to this day, with no diet at all and still no cardio. When I would come off my cycle I continued to run enathate at 300mg per week and still running GH dropped down to 3iu 3x per week, I honestly think the enath was a huge factor in cutting my BF with the GH. When I would start next cycle if it did not include enath I would stop the enath completely and re-start 2 weeks before end of cycle and still do it today. I have been running GH for probably 5 years, took a couple months break here and there because of laps in order. iMO,,, run 3-5iu M-W-F and enath when off your cycle and keep the dose the same, more is not always better, read my next post about Dr O'selle local Doc here in town,,, Try it for 3 months see what results you get.
