Best Alternatives to Science in Sport Beta Fuel Dual Source Energy Gel

Beta Fuel gel is 40g carbs / 158 kcal, dual-source, thick, widely stocked, not high-sodium. Leave it for GO Isotonic if you want thinner 22g packets, PF30/C30 when 30g modular math plus (C30) sodium is the plan, Gel 160 when hydrogel 40g is the texture, or a caffeinated Maurten when late-race caffeine is separate. Stay when fewer 40g SiS packets is how you hit marathon carb targets.
