What Our Gearhead® Experts Are Saying:"When I’m stacking big mileage or racing at threshold, Roctane Gels are what I reach for. The added electrolytes and amino acids keep me from cramping up or bonking, especially on long climbs or in hot conditions. The variety of flavors in the mixed box is clutch for all-day rides."When we’re going long and need more than just sugar to get us there, the GU Roctane Energy Gel Mixed Box steps in with a high-performance fueling solution. Roctane delivers the same 100-calorie carb punch as the original GU gels, but with 2–3 times the sodium and a potent mix of amino acids including BCAAs, taurine, and beta-alanine. That means better hydration support, muscle protection, and reduced fatigue when we’re hours into a climb, grinding out a century, or going deep in a race.
