When should cyclists use the SiS GO Energy + Caffeine Gel?

The SiS GO Energy + Caffeine Gel delivers 22g of fast-absorbing carbohydrate plus caffeine in a single 60ml gel, built for the moments in a race or long ride when you need both a physical and a mental edge. Science in Sport put this on the same carbohydrate platform as the GO Isotonic Gel, then added caffeine to lower your perception of effort and sharpen focus when fatigue sets in. Berry, Citrus, and Orange each carry 75mg per gel, roughly one cup of coffee. Double Espresso carries 150mg, double the standard dose, so choose it deliberately rather than by flavor. Note that this gel is not isotonic, because the added caffeine raises its concentration, so take it with water.

Use one gel 30 minutes before short, intense efforts for mental preparation, or one to two gels toward the end of long endurance events when alertness and power output start to fade. Caffeine has been extensively shown to improve endurance performance by reducing perceived effort and increasing concentration. Do not exceed four gels per day, and count a Double Espresso as the double dose it is. Informed Sport certified, with every batch tested against the WADA banned substances list.
