In reference to this question. If your goal was fat loss, would it be more effective to shoot the 4iu in the morning while remaining in a fasted state (for at least a while after the shot)? Or would it be better to still split the doses 2iu in the morning and 2 iu in the afternoon, but to make sure they are taken while in a fasted state or at least in the presence of little or no insulin.
I get the feeling that the split approach would work better (again for fat loss) because you would have the elevated gh levels twice per day. This is assuming you got the timing right with respect to when you eat your meals.
