GU Roctane Energy Gel

GU Roctane Energy Gel is the brand’s gel formula for longer or more demanding efforts. It combines carbohydrate sources with sodium and an amino-acid blend that includes leucine, taurine, valine, beta-alanine and isoleucine. The flavor panels list 100 calories per packet.

Caffeine varies substantially across the selection. Lemonade is caffeine-free, several flavors provide 35mg per packet, and Cold Brew Coffee supplies 70mg. That makes the exact flavor an important detail when planning multiple packets during a session. GU recommends water alongside gel intake.
