It was in my very first post....53% hemo. I meant HCT.
Nothing wrong with a blood draw I suppose but I'm pretty certain it's not your issue. Sometimes stress or atypical reasons can cause transient cardiomyopathies. I'm not a cardiologist, so I would just follow up with your cardiologist on this. Meantime I would not personally discontinue TRT or worry excessively, especially if you are symptom free in the setting of a high level of physical activity.
Good luck and sorry for being a bit impatient.
