Excellent product
Started using this gel earlier this year and I have had a great experience, it is reliable product easy in the stomach and helps you push and recover when you truly need it!

Yummy
These are easy to eat and give me the energy I need. Tutti Fruity is my fav. The milder sweetness/flavor is nice to have when I usually rely on other really sweet things.

My go to gel
I like the orange with added caffeine pre-race or pre hard session. Tutti frutti is my during the race or if I need some added carbs for a workout. Both taste good and are easy open and drink.
