Product analysis · 8.0 Good
GU Roctane Energy Gel is a energy gel (21 g carbs/serving; 35 mg caffeine). GU’s denser electrolyte-leaning gel line (~100 kcal / ~21–22g carbs per label) with higher sodium than classic GU and optional caffeine flavours — designed for longer efforts when you want familiar GU packaging with a more race-oriented electrolyte profile. I'd shortlist it for higher sodium than classic GU for longer warm efforts. The trade-off is carb dose still sits around ~21–22g — not a high-carb race gel — GU Energy Gel is the cleaner compare when that is most of your week. It fits buyers who actually need a energy gel (21 g carbs/serving; 35 mg caffeine), not a one-product rotation.
