my favorite energy supplement

Coffee.  It works.  I’ve tried NO Xplode, Dymatize Xpand, SAN Fierce, and Cytosport Cytomax (still love this stuff), all with the hope of finding that one product that gives me an even-keeled energy throughout my workout.  And recently I’ve discovered that coffee pretty much rules in this respect. I drink it hot and black, and it hasn’t failed yet.
