Someone(I think 800m) posted studies about T2 in the IBE forum a bit ago, showing that it burns fat, preserves muscle, and increases endurance. If you dont want to run an anabolic with T3 I'd say go with T2 by itself instead. In that same thread I think ThermoLife Dicana is the only one on the market with that specific T2. Not cheap but if it does what it's supposed to, well worth it. Or you might just want to stop messing with thyroid/adrenal hormones alltogether and pick up some Anabolic Pump or DCP, both of which are supposed to be pretty amazing as far as fatloss/recomp properties go with no stims or affect on thyroid.
