Whether it's half way through your work day and you're slowing down or you need a pick me up before your workout, the GU Roctane Energy Gel has got you covered. If you demand the most from your energy sources, Roctane Energy Gel delivers on that demand with amino acids that reduce mental fatigue and decrease muscle damage that will help you keep going throughout the day. A step up from GU's original Energy Gel, Roctane has more sodium and electrolytes for increased hydration. To wrap it all up, 35mg of caffeine gives you an extra boost for your workouts.
