Recommended usage

Consume 1 gel 1 hour before exercise for high intensity, short-duration exercises to ensure the body starts with elevated caffeine levels. In longer duration events consume no more than 2 double caffeine gels per day. Ensure you keep hydrated.


When is the best time to consume the GO Energy + Caffeine Gel?

We recommend 1 gel 30 minutes before short, intense exercise to provide mental stimulation for the race ahead. 1-2 gels towards the end of long, endurance exercise to improve alertness and concentration.

What are the benefits of caffeine?

Caffeine has been shown to increase endurance performance by providing a mental boost, improving alertness and concentration.

Will these upset my stomach?

75mg of caffeine is equivalent to one cup of coffee or one can of energy drink. However, individuals tolerate caffeine consumption differently to others, so make sure you try it out in training, before use in competition.

What does isotonic mean?

The tonicity of a solution refers to the concentration that affects water and carbohydrate transportation across cell membranes, most importantly the movement from the gut into the bloodstream. Ultimately this will affect how quickly the gel can be used as an energy source.

To be isotonic a solution must have the same concentration of dissolved particles as the fluid in the cells within the body.
