Insulin resistance from HGH usage isn't from a certain dosage per say - it's more of a matter of duration. It's a cumulative effect.
It's kind of like this - 1-2 months using HGH, no problem
6 months + of HGH usage, that's when the problems start.
The easiest way to see if you are insulin resistant is to get a blood glucose testing machine (the one diabetics use) and test your fasting insulin when waking.
