I don't know why you would want to do that? I don't know if anyone knows for sure how bad it is or how long it takes to return to normal thyroid function. If it helps, I finished up a t3 and fina cycle and the t3 went:
1=25mcg
11122233344444444444444444443332221111.5.5.5.5
one week after stopping the t3 I had blood work done and tsh, t3 and t4 were all in normal range. Could I have tapered down quicker and still had normal thyroid function after a week? Maybe?
