I've chased cortisol for years in my life with no success. If your sleep sucks, your cortisol will spike. It's a dog chasing his tails.
You can't sleep because because you're running supra physiological hormonal levels.
The sooner you get that, the sooner you will fix your problem.
There are plenty of people on this forum taking ambien, ibuprofen and all that trash to sedate themselves, just because they thought the higher the testosterone the better.
I hope you won't learn the hard way.
Dude, seems you are missing and missing the several times I said I had sleeping and cortisol issues before TRT...
