OK, the question is: HOw long can I take hcg before it starts to cause irreversible (on longer term) suppression of my tiny little brain. I have not been prescribed HCG due to any type 1 or 2 issues, but i have been using to combat testicular shutdown while on TRT or higher doses of testosterone. So if there is anything to negative feedback does this actually apply to HCG usage. Maybe it does not even apply and HCG only "mimics", but I am sure there has to be some message going to my brain and telling it not to make LH, etc. for now while I am supping the HCG. SHOULD I WORRY ABOUT DURATION OF HCG USAGE further shutting my down.?
