Sorry not trying to sound like a dick. I just want to make sure i understand your goals. Please correct me if im wrong. Basically you want to cut fat while maintaining muscle so you can be more healthy and so yo can get mri's. But the down side is when you cut to many carbs you feel like crap? Is that correct? *note i personally think 75mcg of t3 would be fine. I personally dont get good results from t3 unless my diet is about perfect. Buy if it is perfect. My fat loss is considerably more then just the perfect diet alone.
