Which substances are giving me a nice elevation in mood? They are contained in my pre w/o powder. I know the caffeine,theobromine,theophyll ine are giving me a bump but I have used other supplements containing these and not experienced the same mood elevation. The Energy & Nootropic complex consists of: The three compounds above plus L-,Choline Bitartrate, , ,Evodiamine, and Vinpocetine. I have done some research on them but haven't come to any great conclusions. The Vinpocetine is leading the list right now. Any suggestions?
