What Makes GU Roctane Different?

GU Roctane combines maltodextrin and fructose as carbohydrate sources with sodium and a 1425mg Roctane Amino Acid Blend containing L-Leucine, Taurine, L-Valine, Beta-Alanine (CarnoSyn®) and L-Isoleucine.

GU positions Roctane for prolonged and high-intensity efforts. Compared with GU Original Energy Gel, Roctane provides a higher sodium range and a larger amino-acid formulation.

How to Use GU Roctane Energy Gel

GU recommends taking an Energy Gel shortly before activity with a few sips of water. For exercise lasting longer than one hour, GU recommends approximately one Energy Gel every 20–30 minutes while continuing to hydrate.

Individual carbohydrate, fluid, sodium and caffeine needs are influenced by exercise duration, intensity, environmental conditions and personal tolerance. Practise your fuelling strategy during training before race day.
