Why we built it

Two firefighters. One problem on every shift.

We’ve worked the long shifts: back-to-back calls, heavy gear, and not much time to think about what’s in the bottle. We wanted a hydration mix we’d actually keep in the rig.

So we built one. RELENTLESS LABS is two firefighters making supplements for the people who show up when it counts.
