可樂咖啡因（含瓜拿納）能量凝膠

The cola taste is spot-on and the guarana definitely gives it a nice kick—I grabbed the 15-pack to mix flavors and the discount made it a solid deal. They're easy to tear open mid-run and didn't leave that weird sticky mess on my hands.

These little gels got me through the final stretch of my long run without any stomach drama, and the cola taste is spot on. The caffeine kick from the guarana combo hit in about ten minutes, exactly when I needed it.

The box discount on the build-a-box is a nice touch if you're stocking up for a race season. These gels are easy to tear open mid-run and the cola taste is strong without being sugary sticky.
