You'll notice, as many others including myself have experienced while on trt, your DHEA levels will slowly begin to lower. I didn't realize this until I started feeling like crap mentally and physically. Be sure to have your DHEA-S levels checked now, and continue to monitor them over the years. Three years ago I had mine checked, and DHEA-S was below normal, and my endo at the time said this level was absolutely fine. Little did I know he was a total moron, and knew next to nothing about trt. After feeling like sh-t for a couple more years I started adding in a low dose of micronized DHEA, and it made a big difference. My current DHEA-S blood results should be available next week, I'll let you know the difference.
