It's a great stack. It is comparable in mechanism of action to stacking ECA with T3. TT-33 is T2, the main fatburning thyroid hormone, and OEP is supposed to be similar in action on the b2 receptors as ephedrine. I would also consider adding an additional supplement to act on the alpha receptors to further enhance the fat burning effects of your stack. I would look into Yohimbine HCL or Alpha-yohimbine (Alphaburn).
