On basic TRT now have low Cortisol

[ruffcute]

I have been on basic TRT for a number of years now. When I say basic, I mean purely for functional normal level replacement therapy. I take just enough to keep my Free test in the 400-500 mid range.

The last couple of years have been pretty hard, and life has sucked somewhat, divorce, seeing the kids less etc so I know my stress hormones would be a little weird.
But over the last couple of years I have seen my TRT and other general hormones stay normal, but my Cortisol really fluctuate and now staying pretty low.

Here are some of my labs for Cortisol.
Aug 2020 - 490 nmol/L 170-500 range
Feb 2021 - 186 nmol
Oct 2021 - 114 nmol
Dec 2021 - 115 nmol
Jan 2022 - 172 nmol

If you need any other labs, I can happily look them up. I’m just not sure what to write down right now.

Does anyone know why I might be experiencing such low cortisol? Or if there would be a TRT factor?

I think the next step from the doctors perspective might be a ACTH stimulation test.
Unless they decide that 172 nmol is now in the range therefore screw further testing - I had that originally with my TRT.

Current meds I’m on:
Test Cyp - 0.3ml x 2 times a week 200mg/ml
HcG - 300 ui x 2 times a week
Anastrozole - 0.5mg x 2 times a week
