Good supplements aren't cheap. I've tried a broad spectrum of supplements and to tell you the truth stacking Nitrix with NO-Xplode has been the best thing yet. You take the nitrix all day long in pill form and it gives you a small but constant flow of nitric oxide so your muscles stay firm. Right before the gym I take the NO-Xplode and once all the NO2 hits you, your muscles swell up and your lifting far more than you could before.

Make sure you get the newer versions of these and I HIGHLY recommend using the Blueberry flavored NO-Xplode.
