el3ctro...
NO-Xplode also comtains other ingredients that have not been researched extensively and are not proven safe. Taking this supplement does not sound like a good idea to me.
For mental focus...
I take something called SPARK from the advocare line. It contains the amino Jon suggested(L-Tyrosine) and others that create mental focus. I take it before school and before baseball games. I strongly suggest this instead of that NO-Xplode.
