I haven't experienced any further atrophy since TRT but every damn time I upgrade T4/3 dosage I get the very same muscular symptoms. They start to fade away after a couple of weeks. However, I still suffer from significant fatigue that prevents me from exercising, so I haven't yet regained what has been lost.
I do suspect you aren't loosing any muscle mass either, even if it feels so. Talk with your endo about checking cortisol.
Any proper thyroid bloodwork must include TSH, FT3, and FT3. Thyroid antibodies (abTPO, abTG) should be done just once, to check for autoimmune thyroditis (hashimoto's).
