I’m really think the the fear of T3/T4 is way to much over the top. Yes, it has risks. But I would say the gear we put in our body is significantly more risky, especially not done right.
I’ve seen IBFF pros who is in one of my other boards do a test. After 6 months of T3 at 100mcg ed, TSH returned to baseline in 2 weeks. Seen another do a experiment at 150mcg for 2 months and returned to baseline in about 3 weeks. Both posted TSH levels tested.
Although I’ll admit they were all men. Unless there is a reason females thyroid isn’t a resilient?
