Science in Sport Beta Fuel 80 Dual Source Energy Drink Powder, Strawberry and Lime Flavour Carb Powder, 80g of Carbs Per Pack (15 Pack)

Excellent mix, used for half Ironmans with no issues at all. Very decent lightly sweet taste with plenty of carbs, an impressive 80g of carbs (1:0.8) in just 600ml of water. No gastric discomfort, and honestly quite a nice taste and will definitely continuing to use this. Sachets are large (but expected), and price on subscription is great compared to other brands. Recommend it after having tried other brands and flavours.

Why did you choose this product over others?:Use them for rides longer than 2.5 hours for carb top up. Have been using them for years so know that they don’t upset my stomach. Sip it regulary as you ride along with some form of other electrolyte drink

These are good quality energy drink powders. My only issue with them, is that they could improve the flavorings a bit more as the strawberry/lime ones I had were just a tad light on flavour.

Very good and tasty

I usually get cramps in my legs so I am very worried each time I go on cycling sportive epic days.I feel that these SIS is really made a big difference in my fueling. It is very expensive but worth every penny

When it comes to supplements, it is super important you chose the right brand and one you can trust. I have tried dozens of supplements by Science in Sports and not once have I been disappointed. This Beta Fuel supplement is no exception. I have had several sachets for different work outs and I must say I am trilled with the results already.I found that these were most effective for cardio / endurance rather than weight training. This is because of the source of fast absorbed carbs this supplement provides which keeps you energised for hours. I cycle to and from university and found that this drink supplement was perfect to refuel when half way through my 16km daily commutes.The sachet mixes well in water (I found chilled was best) and provides a creamy texture which was tasty (had a nice citrus orange flavour), and hence I did not feel like I was force feeding myself on my brief cycle breaks. I am very happy with every aspect of this product. No side effects or jitters which is important for cycling in rush hour London. I also found that it improved my focus which is key also for cycling on busy main roads. Great value considering quality. 5 stars!Thank you for reading my honest review, I hope you found it helpful! :)

I've used beta fuel during my training and racing for a couple of years now and it's become a permanent part of my race kit.I usually mix up a sachet into a 750ml bottle the night before a race for convenience sake more than anything, I know the instructions say to mix with 600ml but I found it doesn't affect the energy intake as long as you have sorted your fuelling properly, that 750ml bottle over 1 hour will give you the same amount of energy as a 600ml over an hour.I find the powder mixes well and have never had any clumps in my bottle.The taste is nice without being overly sickly, which is nice because I normally drink at least 2 of these during a race and without being too sickly means I'm happy to keep drinking them without feeling sick.These are a little bit on the higher price range for cycling energy, and you can get cheaper tubs that does a similar job. However I have found that as this product does a much better job at fuelling than other powders and prevents any stomach issues that I've had with other powders.

Ok. Didn't give me the runs
