I've recently been diagnosed as hypothyroid ( underactive thyroid). I'll be retested this week and again in 6 weeks, but I'm pretty sure the Doc is going to put me on thyroid meds. I've never used thyroid for Bodybuilding supplementation, but from what I've read everyone prefers T3 over T4. I believe they generally prescribe T4....synthroid, but was wondering if I should try to talk the doctor into something containing T3 instead. What are your opinions ?
