Science In Sport GO Isotonic Energy Gels, Running Gels with 22 g Carbohydrates, Low Sugar, Double Espresso Flavour, 60ml (30 Packs)

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.

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.

Great

Boy do I like this one. Decent price too

I’m not a coffee lover, but I was recommended these for my workouts. I used to feel nauseous after exercising, but after taking one of these, I felt energized enough to do the whole workout again! They’re great for recovery. I wouldn’t recommend using them outside of exercise or physical exertion, though.

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.

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..

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.

Throw them in your vest or pocket. Great taste and a good clean kick during training or a race.

The best kick start I’ve found!

Non ci credevo ma ti dà una carica non indifferente Lo uso quando,nelle uscite in bici, faccio percorsi superiori ai 100km o con alti dislivelli

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