Anyone got any complaints/comments on stacking MuscleTech Nitrotech Hardcore, Controlled Labs Purple Wraath, and Optimum Opti-Men Multi's???

I like the NitroTech Hardcore for my protein shakes. I just think I need to get more BCAA's, in comes the Purple Wraath. I'm tired of GNC's MegaMens so I'm wanting to try some different Multi's. I'm also taking Fusion BB SubQ thermogenic.

Any tips would be appreciated.
