      GU Energy Labs Roctane Energy Gels are designed for longer and more intense exercise than GU’s original energy gels. According to GU Energy Labs, Roctane Gels have three times more electrolytes and BCAAs than their original gel to help delay fatigue and improve muscle contractility for long-duration exercise. These gels have very positive reviews for both effectiveness and taste. They are available both with and without caffeine, but there are only three caffeine-free flavors.
