Let me try this one more time, Cybex......GH alone does NOT cause increased muscle mass. Weight gains associated with GH alone are primarily connective tissue, fluid retention, and growth of internal organs. So increasing the GH dose without changing the rest of the stack will only result in an increase in leanness...which is a good thing if that is your primary goal. I often increase my dose to 9 or even 12 iu in the last month of a 12 week cycle if I am not satisfied with the look I have achieved to that point. I want that paper thin skinned, vascular, ripped look while maintaining size. But if I don't have the mass, I am going to throw in some anadrol or the like instead.
The body also employs natural defense mechanisms in the presence of abnormal amounts of extrogenous GH - the defenses that prevent normal people from developing agromeglia - so there is a point where the effects of GH supplementation are negated.
I am attaching 2 pics. The first is at the end of a 12 week GH cycle where I increased GH, cut back insulin, and tapered androgens the last 4 weeks for a more ripped look. The second is at the end of a GH cycle where I kept GH level at 4.5iu, and increased insulin and androgens for a bigger look. As you can see, it isn't the GH that caused the additional mass.
