Overview
When should cyclists use the SiS GO Energy + Caffeine Gel Box of 30?
The SiS GO Energy + Caffeine Gel Box of 30 gives you a full season's supply of race-ready caffeine gels, each with 22g of fast-absorbing carbohydrate in the format built for the hardest moments of training and racing. Science in Sport put this gel 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 that box 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, or one to two gels toward the end of long endurance events when alertness and power output start to fade. Caffeine has been extensively documented to improve endurance performance by reducing perceived effort and increasing concentration late in a race. Do not exceed four gels per day, and count a Double Espresso as the double dose it is. Informed Sport certified, every batch tested against the WADA banned substances list. The 30 pack is the right buy for athletes who use caffeine gels strategically across multiple training sessions and races.

FAQ
Good questions
Get to know Science in Sport

There's more to Science in Sport than this one product. Our Science in Sport page has the full Science in Sport lineup we carry and more about the brand.
Visit the Science in Sport page →How much caffeine is in each gel?
It depends on the flavor. Berry, Citrus, and Orange each contain 75mg, roughly one cup of coffee. Double Espresso contains 150mg, which is double the standard dose, so one Double Espresso gel delivers what two of the others would. Do not exceed 4 gels per day, and count the Double Espresso accordingly.
What is the difference between the Double Espresso box and the others?
Double Espresso is not simply a coffee flavored version of the same gel. Science in Sport sells it as their Double Caffeine option and it carries 150mg against 75mg in the others. Across a box of 30 that is a substantial difference in total caffeine, so buy it knowing what it is. If you are new to caffeine during exercise, start with a smaller pack of one of the 75mg flavors.
When is the best time to use the SiS GO Energy + Caffeine Gel?
Take 1 gel 30 minutes before short, intense exercise. For long endurance events, take 1 to 2 gels toward the end of the effort when fatigue and reduced alertness become factors. Do not exceed 4 gels per day.
Is the GO Energy + Caffeine Gel isotonic?
No. Unlike the GO Isotonic Gel, this product is not isotonic. The added caffeine increases the concentration of the gel, so it should be taken with water.
How many can I take per day?
Do not exceed 4 gels per day. Caffeine sensitivity varies between individuals, and higher doses can cause jitteriness, elevated heart rate, or GI issues in some athletes. If you are using Double Espresso, remember each gel counts as two standard doses.
