will t3 shut down ur thyroid after taking it?

What's the side effects of taking t3?
I know it wastes through muscle without test. But will it shut down ur thyroid like test shuts down ur testosterone production? Thanks guys

Typically no it will not IF you use it properly.
Just dont take too much,,,for too long. Taper up
and then taper back down off.

Yes. No need to produce naturally if exogenous is present.

This will be something that you will also need to have checked after you discontinue use. It would be helpful if you knew your numbers before starting to use it as a baseline. Mine has slightly changed since I discontinued using T4 and will keep having checked in an effort to see if returns to is normal range. I would try to use it for as short a duration as possible
