How to use

Use Pre-Workout as directed on the pack before training.

Because each serving contains 100mg caffeine, consider your total daily caffeine intake from coffee, tea, energy drinks and other supplements.

Avoid taking caffeine too close to sleep if you are sensitive to it.

Do not exceed the recommended serving.

Not suitable for persons under 18, pregnant or breastfeeding women.

Where it fits

2 – Training performance

Prepare for the session.

Pre-Workout sits in Step 2 of the CoreStorm system.

Its role is to support the pre-training window, when alertness, concentration and demanding training support matter more.

It does not replace Step 1.

1 – Daily foundation
Use Daily Creatine Powder for consistent daily creatine support.

2 – Training performance
Use Pre-Workout before demanding sessions where alertness, concentration and training demand matter.

2 – Training performance
Use Hydra-Creatine Powder when hydration, sweat loss and repeated effort are the bigger priority.

3 – Recovery & repair
Use Vegan Recovery Protein when protein intake, rebuild and readiness become the priority after training.

A system that holds together.

Pre-Workout

Built before the session

Pre-Workout is built for the pre-training window: the point before demanding sessions where alertness, concentration and preparation matter.

It sits in Step 2 of the CoreStorm 1–2–3 performance system – Training performance.

The formula leads with 200mg L-Theanine from green tea extract, paired 2:1 with 100mg natural caffeine from guarana. Creatine, L-citrulline, BCAAs and beta-alanine complete the wider pre-workout formula.

This is not a high-stim pre-workout built for noise. It is a more controlled Training performance product with a clear role in the system.

What you take when it actually matters.

What it delivers

Tennis player in action on a court with text 'alertness and concentration'.

Alertness and concentration before training

Each serving provides 100mg natural caffeine from guarana.

Caffeine helps to increase alertness and improve concentration, making Pre-Workout relevant before sessions where preparation, concentration and training intent matter.

What it delivers

L-Theanine-led formula

Pre-Workout is built around 200mg L-Theanine from green tea extract, paired 2:1 with 100mg caffeine.

That gives the formula its structure and separates it from conventional high-caffeine pre-workouts.

What it delivers

3g creatine per serving

Each serving includes 3g micronised creatine monohydrate.

Creatine increases physical performance in successive bursts of short-term, high-intensity exercise. That makes it relevant for demanding sessions involving repeated efforts, strength work or high-intensity output.

What it delivers

Built beyond caffeine

Alongside L-Theanine, caffeine and creatine, the formula includes:

3g L-citrulline
3g BCAA complex in a 2:1:1 ratio
1.2g beta-alanine
5mg black pepper extract

These ingredients are included as part of the wider pre-workout formula, without turning the product into a high-stim caffeine-heavy blend.

Pre-Workout with controlled caffeine at 100mg per serving

What it delivers

Lower caffeine by design

With 100mg caffeine per serving, Pre-Workout takes a more controlled approach to caffeine.

Built to a higher standard

Pre-Workout is built around a different approach to training support.

Not more caffeine for the sake of it.

Clear active amounts. No vague blends. No guesswork.

Not a high-stim formula dressed up as discipline.

Just a defined pre-workout formula built around L-Theanine, caffeine, creatine and supporting active ingredients.

Performance, built to a higher standard.
