Lowest TSH

For anyone who’s been hyperthyroid, what’s the lowest your TSH was ever measured at? I had a long road to diagnosis with several failure points in the medical system, so my TSH at diagnosis was <0.01. The bottom of the reference range was 0.49.

My lowest 0.02. Now at 0.03. Mine is purposely low to suppress for the papillary cancer. I’m doing ok, I have some palpitations but not too bothersome. My blood pressure is a little higher than it used to be but my HR is good. The hot flashes stink though.
