Designed for endurance and high-intensity workouts, these gels are developed with elite athlete input and scientific precision to optimize physical and cognitive performance on the move. ## 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.
