Science in Sport's new Go Energy caffeine gel double Espresso flavour differs from other caffeinated gels in having 150mg of caffeine, compared to the opposition who tend to offer between 50-89g.
With this mighty boost you would expect to feel a pick up. The taste is not as over powering as you might think given the caffeine content and there is a definite lift in how you feel. You will need to restrict how many you use in a ride, though.
Beside the caffeine content the gels include 22g of carbohydrates. Science in Sport say the body needs 3-9mg of caffeine per kilo of body mass to affect performance. Caffeine can also act as a mental stimulant when you're tired, so a caffeine-loaded gel like this would be best taken towards the end of a long ride, a few hours from the end when fatigue is becoming a factor.
The all important taste: it isn't as harsh as I expected. Don't get me wrong I like coffee but sometimes the prospect of a double espresso can be a bit daunting. However the SiS Go Energy with caffeine is palatable without causing you to wince as you swallow; there is no bitter taste. I certainly haven't tried more than two on a long ride and I'm not sure you would need to. If you feel that fatigued I would suggest calling it a day.
Any energy regime needs to be supplemented with other products so despite the obvious benefits of the caffeine gels you will need to keep on top of your hydration. The SiS Go Energy gel does offer a boost but at £10.99 for six you are paying a premium price so keep in case of extreme fatigue.
Provides a caffeine boost when you need it; tastes decent too
