The funny thing about Craze is that I was late to the party and didn't order my first (and only tub) of it until November 2012, which was at least several months after the "WTF is actually in this?" hype had gone viral.
It was some kind of berry flavor (maybe Berry Lemonade?), and I remember having unbelievably high hopes for it... and yet the first time I took ~1.5 scoops on an empty stomach prior to doing my cardio, I remember that I waited, and waited, and waited on it to kick on... and yet I eventually felt literally NOTHING from it. It might as well have been a stim-free PWO.
So obviously, the "special ingredient" had been removed from the formulation by the time I'd finally gotten around to ordering a tub. I really hope this isn't going to be the case with Excelsior moving forward, but I honestly don't have high hopes.
