Body shape is not a suitable metric to gage whether the dose of hormone therapy is therapeutic or not.
Personally in the absence of symptoms I will be aiming for a minimum of 400pmol/L estradiol for bone and cardiometabolic health. This approximates the average level across a healthy menstrual cycle, leaving out the ovulatory peak.
If I was at this level and still symptomatic, I would increase further, however I wouldn't personally want to be above around 800-1000pmol/L long term.
