What HYDRAX is

A system, not a supplement.

HYDRAX is a modular endurance fueling system designed around how athletes actually train and race. Each formula has a specific role, before, during, and eventually after long or intense sessions, without overlap, gimmicks, or unnecessary ingredients.

The HYDRAX system

A fueling system with jobs, not a shelf of vibes.

Most endurance stacks blur into each other. Ours doesn't. PRIMER is the 25 minutes before you start. CORE is fuel + fluid while you're out there. CREATINE is the daily baseline. RECOVER is still in development, and we'll ship it when it's honest, not when the calendar says so.

Before

PRIMER

Carbohydrate and sodium, including sodium citrate, taken 20 to 30 minutes before a hard session.

During

CORE

Fuel and fluid while you're out there: ~85 g carbohydrate and ~980 mg sodium per serve.

After

RECOVER

A post-session product still in development. It ships when it is ready.

In development

Always

CREATINE

The daily baseline. Not session-specific. Not phase-dependent. Creatine monohydrate underpins every phase of your training.
