Imo, I think you wasted your money... Xyience NOX CG3 isn't going to do a whole lot for you, not to mention, for the price, there are better products out there. From my understanding, it's a NO plus creatine. It be pointless to use something like that before you pitch. You're better off using BCAA's to fuel performance, and aid endurance then a NO booster. Save it for when you lift.
I've used a NO booster in the past-whether or not it actually aided my weight lifting is questionable, but I did see strengh gains while supplementing with Green bulge plus White blood-NO. I also experienced some incredible pumps while supplementing with these, too...
Just load up on good, clean foods before you pitch, and you should be good to go.
Anyways, imo, I think it would be more useful for you to just save the Xyience NOX CG3, and use it when you're working out.
