Science-Backed Dosing
Every recommendation is grounded in peer-reviewed sports nutrition research on carbohydrate oxidation, sweat electrolyte loss, and caffeine pharmacokinetics.
Fully Modular
Unlike fixed formulas, THRESH lets you dose each component independently — 30g to 120g carbs, precise caffeine, and Ironman-grade electrolytes.
Built by Athletes
THRESH was created by a triathlete training for Ironman who needed a system that actually worked at volume. Every dose reflects real race-day demands.
