I have yet to do GH...
But I have read elsewhere that with GH; dosing with T3 is a good idea. GH lowers thyroid hormones.
The only thing I could think of is low blood sugar.
For the slight thyroid suppression that is possible:
conservative - take nothing
moderate - t-100x, bladderwrack, coleus forskolin, selinium, zinc, chromium, copper
aggressive - T3 at a dose of 12.5 - 25 mcgs per day
For the insulin resistance that is possible:
conservative - 300mg of Alpha Lipoic Acid and 200 - 300mcgs of Chromium Piccinolate
moderate - 15mg of Actos - a prescription med to increase insulin sensitivity, Glucophage or Metformin to dispose of excess glucose and increase uptake in muscles.
aggressive - add a few IU's of insulin to your HGH cycle
