Completely Organic and Vegan

Water, glycerine, emulsifiers (lecithin from sunflower), natural flavouring, sweetener (stevia) (citric acid), niacin, potassium choride, caffeine (Only found in Energy sachets), B12, liquorice extract, preservatives (potassium sorbate, sodium benzoate), vitamin complex (vitamin B3).

How to Prepare & Drink EI8HT:

  1. Tear open the top of the sachet completely.

  2. Pour the contents into a bottle containing approximately 200ml of plain water.

  3. Ensure the bottle has some headspace—around 1/3 of the total bottle volume. This space is essential as the friction between the water and the formula in this headspace activates the micro-bubbles.

  4. Close the bottle, shake well, and enjoy!

"It feels just as hard but you’re able to do more. Your ceiling raises. The pain is the same, but you’re on top of it. You make it feel controlled."

Becky Owen - AG-Triathlete 9 Time European Medalist

“As my training intensity started to increase I would be more fatigued and found I would crash within sets. But when I use EI8HT I find I last much longer before fatigue kicks in. Now I am able to stack higher intensity days back to back without feeling drained and scared of breaking”

Sophie - Professional Cyclist

“Unsurprisingly, I could feel the fatigue as the race progressed towards 4hours, however, I felt I was recovering faster than usual on the descents/flatter sections, therefore I was able to attack every climb, and

put time into my competitors.”

EFFE Pro Triathlete

“Normally after 2–3 heavy weeks my legs become flat and I struggle to produce power at the beginning of sessions, especially in brick workouts. This time, even when fatigue was clearly present, I was still able to activate and reach my usual training intensities much faster. I didn’t feel “fresh”, but I felt functional — like my body could still respond instead of staying blocked. For an endurance athlete that’s probably the biggest difference”

“I noticed the fatigue building and I was aware of it but I was still able to push through and hold decent numbers/power. It just made the hard efforts feel more manageable”

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

In Simple Terms:

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.

Take before bed to support overnight recovery.

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.

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.
