SIS BETA fuel is a mix of 2 parts maltodextrin and 1 past fructose. You can get both online but I wanted to make it right at that moment at home. I mixed 30 milliliters of children’s lemonade concentrate mostly for the taste (15 grams of simple carbs) with 60 grams of table sugar aka sucrose so 75 grams of simple sugars. I’ve been fueling my workouts with this mix with great succes so far.… There is also @Dr_Alex_Harrison’s book that contains lots of great info: [https://www.amazon.co.uk/Diet-Endurance-Hydrating-Electrolytes-Performance-ebook/dp/B07YQFXDG1/ref=sr\_1\_1?dchild=1&keywords=dr+alex+harrison&qid=1626781224&sr=8-1](https://www.amazon.co.uk/Diet-Endurance-Hydrating-Electrolytes-Performance-ebook/dp/B07YQFXDG1/ref=sr_1_1?tag=raineoad-21) --- _[View the full topic](https://www.trainerroad.com/forum/t/carb-concentration-in-drink-mix/61027)._
