The fatigue could be brought on by excessive estrogen. You are using 875mg/w of test E. Just the frontload alone put a lot of test in your system. dbol also aromatises strongly. It could also be that Adex doesn’t agree with you. Have you ever used it before? What is your past cycle experience?
You can always try Letro, but I would make a point of being consistent and dosing either Adex or Letro ED to keep serum level steady. The half lives of both Adex and Letro don’t support anything longer than EOD with ED being better.
If you frontloaded test E, you should have frontloaded Adex also. At least 1 mg on first use.
I am currently on 700mg/w test E with no dbol and I am using .25mg Adex ED. I also frontloaded with 1mg on first use. I definitely don’t feel like my dose of Adex is too high and am feeling no ill effects.
On another matter, I notice you are taking your 1 grain of Armour Thyroid 2x/d. Is that one in the morning and one in the afternoon? If yes, does that normally (when not affected by these other compounds) keep your energy level more steady than a single morning dose?
