Yes i've used Fuze before, and at 4 caps a day I can definately feel a difference in my libido. I cant tell you how that would translate to muscle gain though. Tribulus isnt really touted as a muscle building suppliment, but it couldnt hurt.

as for stacking it, you definately want to have your pre and post workout nutrition taken care of. that means protien, dextrose, and maltodextrin. Looking at your sig, I would add in some creatine and citruline malate if you can afford to.

With a good diet and training you will make gains.
