I use 1iu ed 5days on 2days off and I have never heard of females going higher than 2iu a day unless theyre willing to take big risks... Im no expert here but a year is a long time. Be responsible, you are dealing with cell growth over a long period of time so IMO I think keep it nice and low and do your cycles inbetween. I've gotten advice about HGH from a guy whos prepped international pro's and he said that low dose over longer period is, indeed, the trick. But again, the quality of the stuff is important. If its not great quality you may need to take more.
