I have never seen a single shred of reliable evidence to suggest that T3 usage has a negtaive affect on the thyroid long-term. So contrary to popular advice, I began a T3 course ranging from 25 - 50mcg per day... for 12 months non-stop!
I had thyroid tests done while on and my T4 and TSH were below normal, as expected. However, it has now been 3 weeks since my last dose and my blood work done yesterday reflects my T4 at 14.5 (normal) and my TSH at 3.3 (normal is 0.35 to 4.9).
I think my experience suggests that long-term moderate/low dose T3 has no negative long-term effect on the thyroid.
