Sis Go Energy Caffeine Berry 60ml Energy Gel

I find these easy to take as the viscosity means they are not too runny, so don’t spill while I take and run, and not too cumbersome to get through, like more solid options such as blocks. The added caffeine definitely gives the boost to push through on long runs without feeling like it’s too much of a chore - exactly what you need for distance training/events.

Was surprised at the flavour being as good as it was and how easily it went down. I think an attachment of the rip top opening to the package would be a good idea so it's not getting spat out on the road. Would also get a version of this with more caffeine as the amount in it could easily be increased to double the amount and I'd buy that.

I have used the Go gels for a while and have recently started trying the caffeine version.If you like coffee then you should like the taste of these gels, and I think they do provide a little extra boost when running. Usually, they are significantly more expensive than the Go gels, so I waited for a bulk special offer. Unfortunately the use-by date is tighter than I would have liked; so check carefully when responsing to offers.

A great taste and a brilliant item to have for long race events. I found these gels very good when I ran at the Southampton Marathon in September 2021. It was a very hot day and a course which had quite a bit of elevation. The gels came as a valuable boost when I was flagging during the second half of the race.

14 days passed after original promised date, SiS seems not to be able to make progress with UPS (called UPS myself, they require further input from SiS…SiS is made aware; “will send them an e-mail” nothing more, nothing less.But actually this product is great especially if you need a caffeine boost (and already had your espresso)

Usefulness goes without saying.This product is the most innovative energy gel in the world.Highly recommended.I am very satisfied with the delivery, packaging, and product condition.

A real boost when you need it

I use the SIS double espresso gels when I need an extra boost either for significant hill climbs or towards the end of long sportives. I can’t say they’re a taste great but they’re reasonably palatable when you need an extra hit and exhaustion takes hold. There is quite a significant amount of caffeine in these and the recommended amount is two gels in a day. To be honest I have found two to be more than enough in any given ride and as mentioned only use these on the longer all day sportives or mountainous climbing routes. Being the SIS hydro variety you do not need to take water with them. If your a coffee fan then you should be fine with the double espresso taste.

Awesome gels and speedy delivery

SIS gels are far superior to any others. Nice and thin, easy on the stomach and taste divine (particularly Cherry). I only wish I could get hold of the Cola Caffeine ones.

Great for long runs !

I bough this product a couple of weeks ago. I use it for long runs ( >10miles) . It has a nice taste and keeps you going! For me , it doesn't make me feel pain in the stomach as opposite to other products . I would recommend it !

Trusted friends !

I've been using these gels for years and they continue to be a favourite. Not the cheapest on the market but certainly very high quality and history of continuous improvement from SIS. Fuelld were super helpful and very quick to get them out the door and on the road to me, great service 👍
