SIS GO Energy + Caffeine Gel — 22g Carbohydrate, 75mg Caffeine
The PEAK4 expert team selected SIS GO Energy + Caffeine Gel for combining fast-acting carbohydrate with a genuine mental and physical boost, built on the same platform as the GO Isotonic Gel with 75mg of caffeine added.

Ideal for high-intensity racing or the toughest, most fatigued moments of a long endurance event, caffeine acts centrally on the brain to lower the perception of effort.

Adding caffeine increases the gel's concentration, meaning unlike the standard GO Isotonic Gel, this version is no longer isotonic and is recommended to be taken with water.

How to use

Take 1 gel 30 minutes before short, intense exercise, or 1-2 gels towards the end of long endurance events when fatigue sets in. Do not exceed 4 gels per day. Take with water.
