Fantastic products especially the Beta… Fantastic products especially the Beta line . Trying to take onboard more carbohydrates while cycling and feel it's fuelling me really well, with no drop off in performance. Have noticed my recovery seems to be better also when ingesting more carbs. Great products all through the range.

I have tried energy gels from many… I have tried energy gels from many well-known brands, but the only one that felt smooth and effective when ingested was SIS. It seems to be the world's best brand of energy gel. Due to the brand awareness as well as the quality of the product, you can trust it and see it consumed by many athletes, including European soccer players, runners, marathoners, and swimmers. Highly recommended!!

New Rego/Whey Great service and delivery as usual the new products are better packed,however I had to order vanilla love banana but not available,tried new vanilla yesterday very nice great product

Order was never received Order was never received. SiS use Evri as a courier company and unfortunately they are probably the worst! I contacted SiS via online Chat and was told to contact Evri which I did and was then told to contact SiS, not satisfactory! I have now contacted SiS again who are arranging a replacement, original seems to have been lost, fingers crossed it arrives this time! Unfortunately this isn't the first time Evri have lost an order from SiS!!

Great products and great support Great products and great support - I was in contact with their support and they were brilliant and responded immediately. I got next day delivery. I would recommend and I will be getting more stuff especially the chew gels as soon as these ones are used up!
