Expensive, but a game changer for endurance efforts. My go-to fuel. I mix this and use in a concentrate form so I can carry more with me, extending my ride times to 5 - 6 hours (rather than mixing per one water bottle).
Used bonus points to purchase, it seems to work fine for short low intensity rides, but something about it with high temps and intense workouts this stuff doesn't sit well and probably won't purchase again.
Love the GU line of products. I use Roctane gels and powders for most rides over 3 hours. It has everything I need. All I do is worry about drinking water (as needed), as I go.
A little spendy, unless you can get it on sale... but its a greatfast fuel for rides over 3 hours, exactly what your muscles need. I use this form (more affordable than the packets), and mix with water into a 6oz Hammer Flask, then carry 2 or 3 flasks with me as needed. Makes it very easy to consume on the go. Just need a shot every 30 minutes along with water. If I have enough, Ive never bonked with it. Im using Tropical Fruit.
Like that it has caffeine. For this class of product, the taste is better than Skratch, but I like both. Not bad price for what you get. I can drink a bottle per hour plus some chews with no issues.
Has a good blend of maltose and fructose so it isn't overly sweet. Mixes well with water on a ride, just drop it in and shape it up. I have been using both the caffeinated and regular, both are great for long rides when you need calories and electrolyte replacement.
