Amped-up Energy for Athletes
To avoid bonking while exercising, you need a portable source of easily digestible carbohydrates to fuel your muscles. Gu Energy ROCTANE Energy Gels are designed for long-duration and high-intensity training and racing with more electrolytes for hydration and amino acids for your muscles.
GU Roctane Energy Gels are crafted to supply both energy and key nutrients like electrolytes and amino acids to keep you feeling strong and energized. The precise blend of complex and simple carbohydrates will fuel you up, so you feel good, longer. Our huge variety of delicious flavors will save you from flavor fatigue, so you can stick to your nutrition plan and keep going.
What’s the ROCTANE difference? In short, Gu Energy ROCTANE Energy Gels are designed for long-duration and high-intensity activities, when you’re trying to up your mileage or push yourself further. But what does that really mean? It means that ROCTANE Energy Gels are packed with up to three times as much sodium (depending on the flavor), and three times as many branched-chain amino acids as compared to our original Energy Gels.
ROCTANE Energy Gels also have extra amino acids: Taurine can help maintain heart contractility and improve cardiac output during long exercise sessions and beta-alanine can help promote formation of the intramuscular buffer carnosine, which can help delay the onset of fatigue during high-intensity efforts.†
May reduce mental fatigue and help decrease muscle damage during exercise | Delivers ready-to-use energy for athletes and can delay bonking by sparing glycogen stores | Helps enhance performance by increasing focus and concentration while training or racing |

Oversize Items
