I.m not taking t3, but t4 - euthyrox.

I would say find a new doctor, one who believes in T3 therapy. Honestly, in a nutshell you don't need T4 at all.

T4 is a storage hormone also known as a "pro-hormone" who's sole function is the building block that T3, the bio-active hormone, is made from.

Also, on a basic level, Reverse T3 (RT3) is what is made when the "wrong" iodine atom is removed from T4, it's a "mirror image" molecule to T3 and is not bio-active. It gets trapped in the T3 receptor, and prevents your body from responding properly to T3, leading to hypothyroid symptoms despite a normal TSH and normal T3 and T4 levels in the body. This is what we refer to as "Tissue Resistance to Thyroid Hormone".

It can be reversed by getting rid of T4.
