Science In Sport GO Isotonic Energy Gels, Running Gels with 22g Carbohydrates, Low Sugar, Lemon and Lime Flavour, 60ml Per Serving (15 Pack)

Love Sis gels, never have any problems. I've switched to Beta fuel now as need more carbs for the distances I'm doing now but these were absolutely brilliant for my previous training. Never had GI issues, fine from the first use. Taste is not the most amazing but will get used to it over time.

Nice gels, have been using them for more than a year so far. Taste is not bad at all, easy to take in while running, and no negative side effects on digestion. The only thing to know is that you'd probably need some water right after, just to wash off sweet aftertaste

Good value compared to the more “premium” brands. I’ve been using SIS products for 25+yrs and find it easy on my gut. Simple packaging which sometimes is a bit slippery when trying to open after a long time running, plus having a retaining element on the top would be good. Stopping to pick up the tab is a pain if it falls. I find I don’t need to drink with them and for very long events real food is needed but these are a solid and reliable back up that fits easily in my pockets.

Cheapest way to buy the gels. My preferred flavour. High quality product which works for me for 5/10/HM distance.

SIS tend to be the go to gels in our household for long runs. Myself and my husband use them and they keep us both going. He has done a few half marathons using these and really rates them. I use them for my big runs too. They do a variety of flavours, on this occasion we purchased the lemon and lime (as they are my favourite) but they do lots of others too. They are quite pricey but Amazon do regular deals so I tend to check and order when they're reduced. Low sugar content which is good. I like the texture as it's slightly thicker than water, it's more of a gel based consistency which is what I prefer.

The product is as expected. Taste like lemon

As good as ever. A necessity for long trail runs👍

This is a great quality product that I've used for years and years. Flavours are massive now, such a variety, with newly added Cherry and Tutti fruitti. My only gripe is that some of the pouches can be lumpy and have a horrible texture, whilst others are smooth. But it doesn't stop me buying them, but would be nice if they were all just smooth.

Top! Got one for free

Todo llego rapido y perfecto

Geles de buena calidad!!!sin molestias en el estómago y fáciles de digerir

Product bought in June 2025, has a best-before date of September 2025. The gel has already gone lumpy and is very unpleasant. I’d have expected a far longer shelf-life; unfortunately the returns window had already closed when I opened the first packet; I’ve tried several since from the same pack and they’re all the same.

Tenete sempre presente che Il gel sportivo è molto soggettivo. Ognuno deve trovare il più idoneo al proprio fisico. Personalmente con questa marca mi trovo molto bene. Non mi da problemi di nessun tipo e sono molto d’aiuto in gare di endurance ma anche in un semplice allenamento di breve/media durata. Il gusto è molto buono.
