N=1 here, but perpetuem gave me GI issues and I didn’t like the taste. Soy protein? Pass.
I like Skratch a lot, but it’s tough to fuel with. Heed is OK, but I like Skratch better for hydration. Right now I’m fueling with Honey Stinger gel and Skratch. I’ve tried Maurten and Beta Fuel, but not sure about them. Tailwind is my next try.
I like Recoverite (whey isolate, glutamine, carbs, good flavor). Hammer gel flavors are good, and I alternate between those and Honey Stinger whichever is cheapest.
I’m hoping Tailwind works for me. (Not a fan of the recovery drink ingredients, will stick with Recoverite or home made).
