Bit thick but still very good
Really pleased with these, easy to use and work well giving me a much needed energy boost.They are quite expensive for what they are and they are much thicker that the normal gels so for 5* would prefer a bit cheaper and less 'thick'Still definitely recommend though!

A Powerful Energy Boost for Endurance Athletes
I recently tested Science in Sport Beta Fuel Gels during an ultramarathon, and I was impressed with their effectiveness.Key Features:* Enhanced Power Output: The new ratio of maltodextrin to fructose (1:0.8) provides a balanced source of carbohydrates for sustained energy.* Easy to Consume: The gels have a smooth texture and a pleasant taste, making them easy to consume during exercise.* Gentle on the Stomach: I didn't experience any stomach discomfort while using these gels, even during intense activity.My Experience:I used these gels during a mid-race lull when my energy levels were starting to drop. They provided a noticeable boost, helping me maintain a consistent pace and finish the race strong knocking over an hour off my previous race time. The combination of the beta fuel formula and the balanced carbohydrate content seemed to work well for me.Overall:If you're looking for a reliable and effective energy gel for endurance activities, Science in Sport Beta Fuel Gels are a great option. Their unique formula, easy consumption, and gentle on the stomach properties make them a valuable tool for athletes seeking to optimize their performance.

These are my go to
I’ve tried many different gels over the years and these are my favourite so far. The consistency is thick enough that I don’t get covered in sticky residue and it feels more gel like than others I’ve used. Not thick enough to save a bit for later though, once it’s open you need to finish it all or risk being left in a mess. I will say that it doesn’t feel like there’s too much in the pack either, it’s a good amount to not make you want to throw up. It’s easy enough to open, bit tricker when it’s a rainy run but I still managed. It gives me the boost I need and most importantly, doesn’t sit on my stomach and make me feel uncomfortable. It’s also tasty which with these things is a bonus!

Good product
As described, flavour is neither hear nor there. Good size for stashing on a run.

Good but awful taste
They work and provide energy but the taste is awful. On a positive note, they are less sticky than other gels.

making it easy to eat enough carbs
I ate a lot of these on an ultra marathon, they seem to sit a lot better in the stomach than other gels, and the increased amount of carbs mean you need to eat fewer gel packs! I was having 1 an hour with some other nutrition for the entire run.Tasty and easy to eat.

Fantastic experience overall. Will recommend to friends and family.
Dietary supplements are not a substitute for a balanced and diversified diet.
