A ranking a scraper can't copy
The RC Science Score rates each product on the evidence that actually governs endurance fueling: dual-source glucose:fructose carbohydrate (the lever that lifts your absorbable ceiling toward 90 g/hr), a race-appropriate protein-light profile, and — for electrolytes — real sodium delivery. It's computed the same way for every product, from verified data, with the reasoning shown.
