Thanks again for the advice guys. I truly appreciate it.

I'm not opposed to trying out HRT patches, gels, or injections if that's what is prescribed, I just don't have any experience with it, and didn't want to do anything I'd regret in the long term.

I'll look into what tests are commonly run in a complete metabolic lab and will request them if people think it will help shed light on the matter.

Bob89, sorry, I should have been more clear. I was cutting fat until I was happy with the result, and now I'm trying to gain muscle. My lifts are not impressive amounts. For the amount of effort I put in, everybody is shocked that I have not gained more. I was carb cycling and lifting days are heavy carb days.

pittbulldad, I will also research low testosterone and headaches. That would explain a lot if they were related. Did you get them often, or only when working out? I've taken myself off of supplements except for protein powder, and I typically only get them when I work out hard. I keep myself well hydrated. I had a CT scan done, and doc said that the cerebellar tonsils looked like they were hanging low and crowded, but that it might have been the angle it was taken at. He also said he wasn't aware of them causing headaches.
