Release the hounds with GU’s version of rocket fuel—Roctane Energy Drink. The proven combination of glucose and fructose is the most easily and rapidly absorbed form of carbohydrate. And, a high electrolyte content is just what your legs crave to fire properly, while 35mg of caffeine stokes your central nervous system, increasing the release of free fatty acids into your bloodstream, and further sparing your limited glycogen stores. Plus, taurine and beta-alanine improve muscle endurance throughout the grinding hours of a road race, marathon, or triathlon. Branched-chain amino acids speed recovery and reduce muscle damage, histidine buffers against acidic byproduct, and of course the delicious flavors go down easy.
