I built this because nothing on the shelf was calibrated for the heat.

The frustration that started it.

I was using the sauna 4 to 5 times a week. Following the Finnish data Andrew Huberman covered on his podcast. Søberg's research on cold and heat exposure. Bryan Johnson's protocols. All of it.

And I felt worse, not better. Lightheaded by Wednesday. Hungover by Friday. Sleeping like garbage. I assumed I was overdoing it. Cut sessions back. Same result.

I was using LMNT before every session. Plain water in between. Salt on my food. Doing everything the optimization crowd tells you to do.

30 minutes at 180°F drains roughly a liter of fluid. 1,000mg of sodium. 400mg of potassium. A meaningful amount of magnesium. LMNT was built for athletes losing sodium through gym sweat. Liquid IV was built for general dehydration. Nothing was built for sauna heat specifically.

That was the gap.

The build.

I spent six months finding a manufacturer who'd take a small first run seriously. Eventually landed on an FDA-registered cGMP facility in Long Island that produces pharmaceutical-grade supplements for clinical research.

Then I built the formula backward from the loss. 1,000mg sodium to match what a session drains. 400mg potassium because cardiac demand spikes in heat. 100mg magnesium citrate for sleep depth and recovery. 250mg vitamin C to buffer the oxidative stress that heat creates.

Then I stripped everything else. No taurine because of recent cancer-cell research. No creatine because saturation matters more than timing. No sugar. No dyes. No proprietary blends. Every milligram on the label.

The result is one product that does one thing better than anything else on the market.

What we believe.

• The sauna is the most underrated longevity tool we have. The Finnish mortality data is real. The Søberg research is real. The Huberman protocols work.
• The protocol fails when the supplementation is wrong. Most guys quit by month three because they feel worse, not better. That's a hydration problem, not a sauna problem.
• Every milligram on a supplement label should be defensible. If a brand hides behind a "proprietary blend," they're hiding underdosing.
• Marketing should match the product. We don't run banner sales. We don't do hype language. We don't make "doctor approved" claims without naming the doctor.
• Founders pricing exists because launching capital-light forces honesty. The first 500 customers get the price locked for life because they funded the production run.
