Not to beat a dead horse, but I really like
NO Xplode.
I've been taking it on and off for about 6 months now.
I had amazing pumps when I first started taking it. The pumps have tapered off a little bit - I still get a good pump and the energy, focus, and stamina are all still there.
Like anything else - if you think it helps you . . . then it does.
Also, I'll never step foot in another GNC again.
You can get this stuff online for less that $40 easy.
I buy my stuff from ....we have boards sponsors.
