I have been using E-Caps and Hammer Nutrition for a couple of years. I did my last two IMs with nothing but. I also use the products while training. The first thing I noticed was how much better I recovered from my training. Better recovery today means better training tomorrow. During my long workouts and IMs, I use Sustained Energy with a number of E-Cap products. No one I know who uses this stuff has had any of the problems you so often hear about: bonking, bloating, barfing, etc. I strongly suggest that you visit the website at www.e-caps.com
and read about the products. They cost pretty much what other stuff does. The main difference is that they use no simple sugars, colorings, flavorings or fancy lableing. A lot of pros and AGers use these products.
