Old T2 +Coleus forskohlii

I have a bottle of the old T2 and was wondering if I could add plain ol’ Coleus forskohlii to it. Do you think I would get any added benefit or would this be overkill? I don’t want to screw my thyroid up. Thanks in advance…

Personally I’d just use the old regular T2 at higher dosages and then use the forskholii when you come off.
