HGH & DHEA Levels After TRT

[bomb402]

Can anyone give me any evidence of natural endogenous HGH, DHEA, and other endogenous hormone levels pre and post TRT from your experience or that of others? I've heard so much of TRT causing an expedient decline in other hormone levels and want to verify this. I have not found any obvious studies.
Please don't give me any answers without evidence - be it your own or other posts here as I don't really care what your MD told you.
