I been using 1500 mg daily with very little reduction in fbg , im only using 5 ius hgh daily at night only and my fbg is creeping up into into the low to mid 90's ? I may switch to splitting the hgh to twice daily and see how that goes
It's mostly because rHGH suppresses T4 and thyroid hormones are involved in regulating blood glucose.
You don't have to reduce your rHGH dose, just supplement T3
