10 actives · 4 pillars
A formula built on 4 performance pillars
Every ingredient has a job: energy, focus, pump, strength or endurance.

Energy & Focus
The pillar you feel first. Three reference actives: anhydrous caffeine, L-theanine, L-tyrosine.
- Anhydrous Caffeine USP
- L-Theanine
- L-Tyrosine USP
Pillar 02
Muscle pump
More muscle volume and better blood flow during the effort — the "pumped up" effect.
- Pure L-Citrulline
- Glycerol
- Himalayan Pink Salt
Pillar 03
Strength & Endurance
Strength, power and muscular endurance. Delays the burn during the effort.
- Beta-Alanine
- Taurine USP
Pillar 04
Optimisation

hidden doses. You see it all.
Zero hiding places. You see EVERYTHING.
The "proprietary blend" is a catch-all total that hides the real doses — very handy for masking underdosing. Here, every milligram is shown.
The "proprietary blend" is a common practice in this market.
8g
the citrulline dose that was studied
8 g of citrulline. The real dose, not the decoration.
The dose from the reference meta-analysis. Plenty of brands settle for 4 g "to look good" on the label. You go up to the dose that counts.

Capped at the ANSES limit.
Some US pre-workouts throw in 300-400 mg per serving, outside European standards. Here, the slider is locked at 200 mg — the ANSES limit, full stop.

The studies behind our doses
All our dosage ranges are calibrated on peer-reviewed scientific publications. Here are the 4 main ones.
Caffeine · Mental Drive
21 studies: strength and endurance performance
Caffeine is one of the most studied actives in a sporting context (e.g. the Grgic 2020 meta-analysis, 21 studies). Scientific information presented on a factual basis — no health claim is made for caffeine (EFSA/ANSES regulations).
Citrulline · Muscle Pump
12 studies: reps to failure & pump
According to a meta-analysis of 12 studies (Trexler 2019, European Journal of Sport Science): citrulline (≈8 g) supports performance on repeated sets to failure and perceived muscle recovery after the effort (a pump effect from 4g through nitric oxide vasodilation).
Beta-Alanine · Power & Stamina
40 studies: performance over 1-4 minutes
According to a meta-analysis of 40 studies (Saunders 2017, BJSM): Beta-Alanine 4-6g/day x4 weeks improves performance on efforts of 1-4 minutes through muscle carnosine saturation (pH buffer). Tingling (paraesthesia) is normal, temporary and reversible.
L-Theanine + Caffeine · Mental
Focus synergy & anti-jitters
According to the Kahathuduwa 2017 study (Nutritional Neuroscience): L-Theanine 200mg + Caffeine 160mg supports attentional accuracy and reduces perceived mental fatigue versus caffeine alone.

Frequently asked questions
Got a question?
15 answers to the questions worth knowing before your first tub — practical and scientific.
It is my first pre-workout, where do I start?
Starter format (15 servings) at "Mild" intensity: doses that are effective but light, so you can test your tolerance. You can step it up afterwards.
What is the difference between Simple mode and Expert mode?
Simple mode: you choose sport + intensity + flavour + format → we calibrate the 10 actives for you.
Expert mode: you set every dose to the milligram. For people who know exactly what they want.
Expert mode: you set every dose to the milligram. For people who know exactly what they want.
How and when should I take it?
1 scoop in 300-400 ml of cold water, 20-30 min before training. Mix for 20 seconds. One serving a day maximum. Take a week off every 8 weeks to stay sensitive to caffeine.
How long will my order take?
Read the shipping policy for preparation and transit times. Available methods, fees and destinations are confirmed at checkout based on your address.
Composition and transparency?
Transparent composition, with no banned stimulants (DMAA, ephedrine, yohimbine and the like). Every active is shown to the milligram. Before an official competition, check the regulations in force on the day.
Can I cancel it after building it?
Contact us as soon as possible to request a change or cancellation before production starts. It is effective only after our written confirmation. Read the applicable terms.
Is the −10% subscription commitment-free?
No commitment at all. Cancel in 1 click in your account area. You can change your formula at every renewal. Delivery charges follow the usual thresholds (pickup point free from 49 €).
Are there any side effects?
Normal effects: tingling skin (beta-alanine paraesthesia — a normal, temporary and reversible sensation; tolerance usually builds in 2-4 weeks) and mild mental stimulation (caffeine). If you are sensitive, choose the Mild intensity or switch on "Stim-free" for the evening.
Delivery: how much, and how long?
Read the shipping policy for preparation and transit times. Available methods, fees and destinations are confirmed at checkout based on your address.
Why 8g of citrulline and not 4g?
The Trexler et al. meta-analysis (2019, European Journal of Sport Science) shows that the maximum effect is at 8g. At 4g, the effect is suboptimal. Most brands put in 4g for reasons of cost, not effectiveness.
Why cap caffeine at 200mg?
ANSES recommends 200mg max per serving (Opinion 2013-SA-0212). Above that, adverse effects increase with no extra benefit. Many US pre-workouts go over 300-400mg/portion — outside European standards.
Beta-Alanine: daily or one-off?
The effect is cumulative over 2-4 weeks. Beta-alanine gradually saturates the stores of muscle carnosine (Saunders 2017, BJSM). The tingling (paraesthesia) is normal and shows that it is working.
Why a caffeine/theanine ratio of 1:1 or 1:2?
The Kahathuduwa 2017 study (Nutritional Neuroscience) uses caffeine 160mg + theanine 200mg: sustained attentional accuracy and reduced perceived mental fatigue, versus caffeine alone. In the builder, each of the two doses adjusts to the milligram — up to 200 mg each.
Is piperine just marketing?
Genuinely useful. Piperine (black pepper extract), dosed here from 0,5 to 2 mg per serving, is studied for its role in supporting the uptake of certain actives. The aim: absorb what you take better, without adding more of it.
How does glycerol work?
Glycerol draws water into the muscle cells (hyperhydration) — pump and prolonged hydration. The Patlar 2012 study (Journal of Sports Science & Medicine) observes support for blood volume and for endurance performance with a glycerol serving and ~500 ml of water before the effort.
Precautions for use
High caffeine content (up to 200 mg per portion): not recommended for children or for pregnant or breastfeeding women. Do not exceed the recommended daily dose.
Food supplement. It is not a substitute for a varied and balanced diet or a healthy lifestyle. Keep out of reach of young children.
