Science in Sport Go Isotonic Energy Gel with Caffeine, Double Espresso, 60ml (6 Packs)

Helped me to do London to Brighton

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.

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 taste pretty nasty, not like any espresso I've tasted; however, the taste doesn't last long. After the strange flavour has gone, you definitely get a good caffeine kick and lasting energy through the gel. I don't train for traditional endurance such as running, riding etc, but having once of these before a gruesome long gym session will really help you power through tough workouts. I do prefer a more traditional powdered/liquid pre-workout, but there's no reason you shouldn't give these a try.

Great

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..

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.

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.
