Karbolyn is the Outlast, Outmuscle, Outperform carbohydrate. It took over seven years to develop this ground-breaking technology, and after just one use you'll see why. Karbolyn offers the best of both "simple and complex carbohydrates": It absorbs fasts like a simple sugar, yet supplies your muscles with the sustained energy of complex carbohydrates. Now you can 'carb-load' in minutes and without stomach bloating. If you want a pure, clean carbohydrate source that's quickly converted into muscle glycogen (your body's powerhouse performance fuel) lightening-fast, this is it. Karbolyn is 100% gluten-free/stimulant-free and can be used pre-workout, during training or an event, or consumed after exercise to accelerate recovery.
