My wife has been using t3, on and off (mostly on), for 4 years or so now. I have been after her to come off for a month or so and get her TSH levels checked, just to make sure she hasn't damaged her thyroid. She did, and it came back 1.94. Normal range is 0.44 to 4.47. This just reinforces what my research has found...thyroid levels return to normal, after using t3...well, in her case it did . Just thought I'd share this info, in case anyone else is using or is going to use t3 in the future.
