Science In Sport Reviews

I have been using the SIS products for triathlon training for years. The gels are easily digestible, and provide sustained energy for long sessions. I prefer the caffeinated ones, especially cola. The electrolyte hydration tabs also come in cola and are a must try. For recovery, the chocolate Rego protein powder tastes great and mixes in smoothly with ice and milk in my magic bullet.

Great products and excellent customer service. The SIS Go Electrolyte Powder in Orange flavor is my go-to on the bike.

Good mix of different products. Not keen on the energy bar, but will definitely buy the other products again.

Good produkts as usual but to much “air” in the package and one tube of hydration tablets had broken, were some of the tables was crushed and all over the rest of the package content. //E

The gels could taste better but they work. The energy bakes, again work but the only problem I've got is not eating them before I ride. Coming home from work watching TV working in the garden they have gone before I even get on the bike.

Great service yet again and great tasting hydro tablets

As always, top quality products (gels and soft bakes this time), however, it took more than a week to receive them, which is a bit of a let down. Also, because they are shipped from the UK to the Netherlands, once they arrive in the country, the tracking number doesn't work anymore as they change transport company.

many items out of stock lately, otherwise all good

I never got my product. I realize some of that is probably a FedEx issue however no attempt was made by the company to get my products to me once it was clear the shipment wasn’t coming. I was able to cancel my order after a month and received my money back no issues there. I’m not likely to order again. A friend told me it was great stuff and I’m an endurance athlete but I’ll go elsewhere. It’s essential to be able to get your nutrition when you need it. If you don’t receive before a big race your body has to be used to something else. That’s a definite no go!

Didn't receive anything. And when i ask where my package is, i get a email that It is making Nice process.... No It isn't...weeks are gone now and i don't have anything. Never order here again

I haven't received yeet

Great product. Love it, gives me tons of energy.
