What our customers say
Fatigue isn’t just running out of energy. In trained athletes, output often drops before fuel is exhausted or fitness is limited.
As Fatigue builds:
- Your body uses what it has less efficiently
- Reactions and responsiveness slow
- Output drops even though effort stays high
- You’re still working hard, but getting less back
EI8HT is designed to operate in this gap between the capacity your body has and what you can actually access when tired.
Most athletes don’t fade because they’re empty. They stop because fatigue gets in the way of going again.
EI8HT helps you use what’s already there under load so you can hold the peak when output would normally drop.

HOW AVROX WORKS
Energy comes from your muscles using oxygen to make ATP — the fuel that keeps your legs moving.
At easy pace: oxygen supply meets demand.
At high intensity (hard sessions & races): oxygen demand rises faster than supply.
When that happens:
Energy production drops
Legs feel heavy
Rhythm breaks
Pace fades
AVROX is formulated to increase usable oxygen at the muscle cell level when intensity rises — so your body can keep producing energy deeper into hard efforts.
This isn’t a stimulant. It doesn’t replace carbs. It helps the part of running where effort is highest.

Maintain output as fatigue builds.

Why athletes use AVROX
Most athletes lose performance, not because they have run out of fuel but because it's harder to access when fatigue starts to build.
EI8HT supports how your body utilises available capacity under load, helping sustain peak output when it would normally decline.

When it matters
The pace starts to feel uncomfortable
Intensity stays high
Focus begins to fade
Effort is there, but output isn’t
That’s when the difference shows up — between backing off and staying in it.

A catalyst, not a shortcut
It doesn’t replace training. It doesn’t bypass fatigue. It doesn’t add artificial ability.
It’s used as a nutritional catalyst — helping the body respond better to effort when tired, by supporting use of:
Existing physiological capacity
Available energy and substrates
The nutrition already taken on

Used across training, competition, and recovery
Daily training
Key performance sessions
Races and matches
Recovery between hard efforts
Not as a crutch or shortcut— but as support when repeat effort matters.
