I know your not a new guy and I wasn't going to ask you for stats and cycle history and stuff.
At 35 you should get benefit. 4iu's would be the minimum dose and a minimum time would be 3 months. The longer you run it the better. So, get more hgh or save your money, it's an expensive hobby.
You could string out what you have and do 4iu's a day mon-fri and then have the weekend off from it. I currently do 10iu's EOD, but i've seen little difference from doing it at 5iu ED and I wouldn't bother spliting the jabs morning and night either as some people like to do, I just do one before I go to bed.
You are missing something simple. If you have a vial of hgh with 10iu's in it and you add 1ml of bac water to that vial, then every .1ml will = 1iu. So if your doing 4iu's a day, if you used 1ml of bac water then .4ml = 4iu's
Is that any help?
