As Double Espresso contains 150mg of caffeine per gel, it should not be used in the same way as a decaffeinated GO Isotonic gel. For the remaining carbohydrate intake during a long session, it is often better to combine with decaffeinated gels, sports drinks, chews or bars.
Double Espresso is the stronger caffeine variant in the SiS GO Energy + Caffeine range. SiS lists 150 mg of caffeine per gel on the official product page.
Caffeine can be useful when planned correctly, but it should be counted alongside caffeine from:
Coffee
Energy drink
Cola
Tea
Other caffeine gels
Caffeine tablets
PWO and other supplements
Caffeine sensitivity varies greatly, so test Double Espresso during training before using it in competition.
A practical approach could be:
Take the gel 30–60 minutes before a short intense activity.
For longer runs: save the caffeine gel for the latter part of the activity.
Use caffeine-free products for other energy intake.
Drink water or sports drink as needed.
Add up the caffeine from all sources during the day.
Double Espresso is particularly suitable when you want a planned caffeine dose:
Before a hard interval workout
Before a start where caffeine is tested in advance
During the latter part of a marathon
Towards the end of a bike race
During a long trail or ultra distance
Before a demanding climb or finish
When you want caffeine without drinking coffee
The product should not be used casually with every energy intake, as the caffeine content is high.
SiS describes GO Energy + Caffeine Gel as easy to consume straight from the package. However, it does not replace fluids during longer activities.
Plan liquid separately according to:
Temperature
Humidity
Intensity
Activity duration
Individual sweat loss
Other electrolytes and sports drinks
Water combined with the gel can also make the caffeine and espresso taste milder.
