ENDURANCE FUEL

Endurance Fuel for the Few Who Don’t Quit

You Don’t Need Another Gel.

You Need Fuel That Respects the Work.

Most energy gels are built for finish-line tourists — high on sugar, low on substance. You’re not here for that. You’re training for hours, for miles, for heat, hills, and heart-rate ceilings. You burn clean, go long, and demand more from your body — and your nutrition.

Brutal Salty Energy is a fat-based, salt-forward endurance fuel made for athletes who suffer on purpose.

We formulated it for the few who understand what it means to stay in the fight — trail runners, cyclists, and triathletes who know that fake energy is worse than no energy.

This isn’t for everyone. It’s for those who train like it matters.

What Is Keto Endurance Fuel — Why Does It Matter?

Keto endurance fuel isn’t about trendy diets or metabolic hacks. It’s about training the body to burn fat efficiently, to stay steady, and to avoid the crash. While sugar gels overload your system with glucose and leave you chasing the next packet, our fuel works with your body — not against it.

Here's how it’s different:

  • Zero sugar
  • Fat-based for steady energy
  • No insulin spikes, no gut bombs
  • No fake fruit or lab candy flavor

If you're a fat-adapted athlete, or trying to become one, this is your weapon.

Brutal Performance

You’re out there when most people are still asleep, still making excuses. Up the mountain. Down the trail. Into the dark. You don’t need a gel — you need a tool. Something that keeps your system stable, your muscles firing, and your gut unbothered.

Brutal Salty Energy delivers dense calories, high electrolytes, and a formula designed for those who push longer than one hour and harder than one session.

This isn’t for weekend warriors. This is for athletes who want to outlast their own limits.

Who This Is For?

Endurance athletes

  • Trail runners, putting in 20–80km efforts
  • Cyclists, grinding through gran fondos, gravel races, and training blocks
  • Triathletes, balancing long sessions across three disciplines
  • Marathoners, who want to avoid sugar spikes and stomach wreckage
  • Mountain bikers, pushing climbs and technical endurance
  • Swimmers, needing clean burn before early AM training

If you demand a fuel that doesn't quit before you do — you're in the right place.

Salt-forward Fuel

One pouch = 360 calories + 24mg sodium.

No carbs. No filler. Just dense, usable energy for athletes who understand their output.

We don’t hide behind flavors. We lead with sodium, fat, and performance clarity. When you feel the gel go down, you know it’s working — because your legs keep firing, your brain stays clear, and your gut stays quiet.

This is keto endurance fuel, built for when performance matters more than taste.

We Built BSE for the long Fight.

Sugar Gels Were Built for 10Ks.

Most gels dump 20–30g of sugar in your system and call it “performance.” That’s not fuel — that’s panic. Sugar gels give you spikes, gut cramps, and a 45-minute crash that costs you more than it gives.

Brutal Salty Energy flips that model. No sugar. No crash. Just +300 clean calories from fast-burning fat and critical sodium — because endurance is war, and sugar’s the enemy.

If you've ever cramped mid-race, bonked at the turnaround, or spent an hour chasing your stomach instead of your pace — you already know.

Keto athlete refreshing

Not for Everyone.

You’re not here to optimize your wellness.
You’re here to earn it.
To grind when no one’s watching.
To fuel up, shut up, and go again.
You don’t crave comfort. You crave clarity
and the freedom that only suffering brings.This isn’t “self-care.” This is self-discipline.

Brutal Salty Energy is your companion in pain.
Salt-loaded. Fat-fueled. Bullshit-free.

Hard Questions, Straight Answers

Is this actually keto?

Yes — completely. No sugar. No starch. It's fat-fueled, salt-forward, and built for athletes who run on ketones. That said, endurance athletes sometimes benefit from 5–10g / hr of carbs during long sessions — not for fuel, but to support liver glycogen and delay fatigue. Don’t worry — that doesn’t kick you out of ketosis. It supports it. This isn’t about dogma. It’s about output.

Can I use this if I’m not doing keto?

Absolutely. Many athletes use it to stabilize energy and digestion without needing to be fully keto. It works for anyone who trains long, sweats hard, and wants to avoid sugar spikes.

Why sodium still matters?

Each pouch of Brutal Salty Energy contains 30mg of sodium — not to overload you, but to support baseline cellular function and water retention. Sodium is critical for nerve signaling, muscle contraction, and hydration regulation — especially under endurance stress.

In the future, we’ll be relaunching our proven electrolyte formula — designed to stack seamlessly with our fat-based energy system for full-spectrum endurance fueling. Until then, pair Brutal with a trusted electrolyte source if you’re training long, hot, or heavy.

Will it mess with my stomach?

No. That’s the point. Brutal was built to avoid gut bombs, bloating, or sudden “oh no” moments mid-race. It’s tested in heat, in effort, and under stress.
