Gh will tend to favor gaining weight more than fat loss or I should be more specific..is muscle and bone density gain. THe main mechanism at work with GH is muscle preservation rather than fat loss. When ppl starve or dont eat GH levels seem to rise the highest. I think there is def some missunderstanding about GH being a fat loss agent. Diet is far more important in geting defined than GH.
Another twist with the GH is that with high GH results in higher IGF. Now IGF does tent to burn some fat but it also has the weird ability to make a person insulin resistant, temporarely anyway. When that happens you suppose to starve so adding food will just make you bigger, good for weight gain bad for fat loss.
So far I have not been impressed with the GH for fat loss but I've been impressed with mass and bone gain. The females I've seen take GH all gained muscle mass and increased bone mass and same thing happened in males.
Hope this helps
