## Description

Product Description Consume 1 gel 1 hour before exercise for high intensity, short duration events to ensure the body starts with elevated caffeine levels. In longer duration events consume no more than 2 gels per day. Ensure you keep hydrated. This product is not intended for children, under 16's or pregnant women. Where hydration is important, SiS GO Energy + Caffeine Gel 150mg can also be consumed with SiS GO Hydro or GO Electrolyte to ensure a combination of energy, caffeine and fluid delivery during exercise. When pushing yourself hard, your brain controls how fatigued you feel. Caffeine acts as a stimulant on the brain to lower your perception of effort, allowing you to keep pushing and maybe stretch yourself a little further. 3-9mg of caffeine per kilo of body mass has been found to affect performance. 5 mg per kilo of body mass is thought to be beneficial for endurance performance, which for a 70kg person would equal 350mg. It can take 30-60 minutes after consumption for caffeine levels to peak in the blood, so if you are doing a short duration event (less than 60 minutes) you should take it before you start. Ingredients INGREDIENTS: Water, Maltodextrin (33%), Flavouring, Caffeine Anhydrous, Gelling Agents (Gellan Gum, Xanthan Gum), Acidity Regulators (Citric Acid, Sodium Citrate), Sweeteners (Acesulfame K, Sucralose), Preservatives (Sodium Benzoate, Potassium Sorbate), Sodium Chloride, Antioxidant (Ascorbic Acid), Pyridoxine HCI, Folic Acid, Cyanocobalamin. P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Directions Consume 1 gel 1 hour before exercise for high intensity, short duration events to ensure the body starts with elevated caffeine levels. In longer duration events consume no more than 2 gels per day. Ensure you keep hydrated. This product is not intended for children, under 16's or pregnant women. Where hydration is important, SiS GO Energy + Caffeine Gel 150mg can also be consumed with SiS GO Hydro or GO Electrolyte to ensure a combination of energy, caffeine and fluid delivery during exercise. Safety Warning For adult use only. Do not consume more than two gels per day. Maintain proper hydration. Not intended for children, pregnant women, or those under 16.

Review: Good coffee taste. - As long as you really like coffee this is the one for you. It will give you that little boost mid ride,you do need to wash it down with a little water as like most gels it sticks in your mouth.
Review: No riders bonking!! - The flavour is like a poor quality cold brew coffee, but the effectiveness with the caffeine was worth it. Helped me to stay alert without feeling wired, and no side affects such as racing heart beat.

### ⭐⭐⭐⭐ Core Gel
*by J***N on 23 July 2018*

Go down with no issues, taste is inoffensive and they give the required boost. Only small issue is they can be a little fiddly to open and you end up getting sticky gel on your hands that you have to deal with for the rest of your run
