Science in Sport GO Isotonic Energy Gel 6 x 60ml Orange – Fast-Acting – Vegan – Formulation with 22g of carbohydrates, a great source of energy

I love these gels for my long runs and triathlons. I really feel the burst of energy I get after taking one, lasts 20-30mins. But they are crazily expensive. This pack was the best value this time, but other times different formats and flavours are on deal so search around on amazon and eBay to find the best value. All the flavours are great.

Taste great easy to eat on the go gives a great boost during cardio sessions 👍

I've been using these gels for a few years now, bought them off here because the price per unit was a lot better than I've seen in shops or elsewhere online. As always, they give a quick burst to your energy levels, so if you're at the end of a long ride/run and need something to take you through the last stretch home they're ideal. Easy to eat on the move, however when opening sometimes the tear-off bit comes off completely and some accidental littering can occur. If you're not too aggressive with opening it's easy to avoid though. The flavour is... palatable. As with most, if not all, of this type of product, they're designed to be consumed, not enjoyed. It's a very sweet, slightly fake-orange flavour. I would recommend this product, not for long term nutrition, but for a quick and easy pick-up. It can also be useful for emergency rations/in a first aid kit.

I use SIS gels as they suit me for longer rides. Important to take them before you’re tired for best effect. Always buy in box of 30 as you can get the best discount…vary the taste choice based on best discount…not a fan of the caffeine versions

Your isotonic gel of choice is completely personal preference as some tend to cause various side-effects. However, I have now tried s few different brands and I have found that these SIS Go to be just right for long runs (or other endurance events). The pack size is not too bulky and will fit snugly into most belt holsters or pouches, the consistency of the product is probably the best of both worlds - not impalatebly thick such that you end up gagging, nor is it so liquid that you might as well be drinking lucazade. I occasionally get irritation around my mouth because of the foil packaging - this isn't ideal, and I did consider dropping a star for it. However, I have since reflected and decided that it is likely to be my technique. The past suggests one every 20 minutes which I would say is fine if you are running no more than 12 miles (20km) or so. If you want to go any further I strongly advise you to ration them to perhaps once every 40 minutes otherwise you'll spend the next two days occupying the toilet in rather a lot of discomfort. As for the taste - these orange ones are the most palatable and the lemon ones are not too bad either. I suspected that they may taste of old army 'screech', but they are actually rather tasty. I now use SIS regularly for long runs (I actually don't bother for anything less than 10km). One every 40 minutes and sips of water as I go appears to keep me moving

I’ve used SIS gels for years. Got these for Trimpell 20 & Leighton Hall Trail half training runs. Ready for the Marathon now. I use 1 after 10k then every 3-4K depending on how I feel. I back them up with Oat Bars/Flapjacks as I get hungry. These gels work a treat, definitely keep you going when it starts to get tough.

Good product. However check the use by date, they have a habit of being within 8 weeks when purchased. Annoying.

Orange SiS gels are my favourite, so good to find a box of them where each gel works out better value for money than in the supermarkets. Provide the energy needed, easy to open and handy to have the box to keep them all together. Box is probably too big for the gels inside, but that’s hardly a problem!
