The original GO Energy Gels by Science in Sport – but with a kick.

In case you don’t know, the GO was key in changing the game. They effectively deliver an easily digestible and quick supply of carbohydrate.

The SiS Caffeine Gel is based on the same formula as the innovative SiS GO Isotonic Energy Gel BUT with the addition of 75mg (or 150mg!) of caffeine. Fast energy with a mental and physical boost.

Unlike the lingering caffeine taste from most products, the GO Energy + Caffeine is clean in the mouth and easy to digest.
