Lets say, a normal healthy male in their 20's, how many iu's a day do you think our bodies make? Big A over at ProMuscle said that the body makes around 4 ius a day, so its pointless to run 2-4 ius of GH because you are merely overriding the bodies natural gh production, but that sounds fishy to me, because lots of people see some gains at the 4 iu mark. What do you guys think? Im thinking its probably less than 1 iu a day.
