Science in Sport GO Energy + Caffeine Gels, Double Espresso, 30 x 60ml

For coffee lovers these are great. Best gels I've bought.

Helped me to do London to Brighton

Easier than grabbing a Starbucks and easy to get down before and during a run. Or even a shift in the go at work. Wish they did them in packs of 50!

First off, these work - they've given me a stamina boost when I thought I was just too zonked to do any gym, and you feel that caffeine pep-up pretty quickly after downing one. That's not surprising, as the science behind them is what makes the difference in the company's other great workout product, Science in Sport 60 ml Go Isotonic Energy Gel Selection Box - Pack of 20 . The espresso flavour that I tried just isn't as pleasant and easy-to-down as the fruit variety pack, though, and I found there was a bit of a lingering aftertaste, so I'll probably be sticking with the fruity ones. For carbs + caffeine, though, you can't get a much easier boost than this.

The flavour is like a poor quality cold brew coffee, but the effectiveness with the caffeine was worth it. Helped me to stay alert without feeling wired, and no side affects such as racing heart beat.

Love SIS gels and been using regularly as easy to take and little mess. Need caffeine ones for my marathon. Tried these before a long run and omg, they taste foul! I love coffee, but these left a nasty taste. Couldnt shake it even 30mins into my run. They may be ok for some, but the after taste would really have me in a bad place on race day.

As long as you really like coffee this is the one for you. It will give you that little boost mid ride,you do need to wash it down with a little water as like most gels it sticks in your mouth.

These are honestly gross, they taste like coffee + metal + chemicals.. but they do the job, so suck it up, but crikey sis do something about the taste..

Super lecker und das Koffein geht sofort ins Blut. Für lange bikepacking Races perfekt.

La solita qualità dei gel SiS ma con una sapore decisamente più gradevole della media. Spesso succede che questi gel siano molto buoni quando sono freddi da frigo ma, una volta scaldati dal sole, diventino delle pappette pesanti e sgradevoli. Questo, viceversa, ha un sapore che si situa a metà tra il caffè e la cioccolata ed è quindi perfetto sia freddo che caldo. Più che consigliato!

The best kick start I’ve found!

Well known product to me and use it regularly for running.
