4g
The output layer
A full creatine dose for more output in short, hard efforts — the most tested supplement in sport.*
80mg
Clean energy
Espresso-strength caffeine with B3, B6 and B12 — drive without the pre-workout theatrics.
30
Built for consistency
Sugar-free, easy-mixing, 30 servings a box — the espresso and the sachet, one habit.
The Mechanism
01
Creatine drives output
The most tested supplement in sport — 4g daily keeps muscle stores saturated for repeated high-intensity efforts.*
4g daily02
Caffeine sharpens it
The ISSN position stand (Guest 2021) confirms caffeine improves strength, endurance and alertness at doses like this — the most evidenced aid after creatine itself.
80mg03
B vitamins keep it steady
Niacin, B6 and B12 contribute to normal energy metabolism and reduced tiredness — EFSA-authorised claims, not marketing.

4g
Creatine per serving — a full daily dose, every sachet.*
80mg
Caffeine — espresso strength: enough to lift output and focus, not enough to wreck your sleep.

Servings per pack — months of the habit at £0.18 a sachet.
Espresso-strength, crash-free
The proven kick
Improves alertness, reaction time and power output across strength and endurance sport — at espresso strength, below the dose where jitters and crashes start.
Energy metabolism
Contribute to normal energy-yielding metabolism and the reduction of tiredness and fatigue — the pathways caffeine borrows against, restocked.
The output layer
While caffeine works today, creatine compounds — saturated stores mean more output in every short, hard effort, session after session.*
The First Month
Muscle saturation
~25%
When to tear
One scoop · 300–500ml cold water
01
Foggy mornings
Brain fuel for the hard days
Gordji-Nejad (2024): a single creatine dose before 21 hours of sleep deprivation raised brain phosphocreatine, dropped subjective fatigue and beat baseline processing speed.
02
Pre-training
Strength and power
Half a sachet in 300–500ml of cold water, 30–60 minutes before. Hummer (2019): +13.4% back squat 1RM and +26% concentric work over six weeks vs placebo.
03
Post-training
Recovery and retention
Co-ingesting creatine with carbs raises whole-body retention ~60% (Green 1996) — and the caffeine has cleared by evening while the creatine keeps compounding — output today, saturation for tomorrow.
04
Daily maintenance
The unsexy one that matters most
Half a sachet, every day, rest days included. The long-tail benefits only show up if you stay saturated — and the ISSN position stand supports long-term daily use as safe.
Timing
Take it at a consistent time. Most people take it in the morning, or before/after training.
Results
Benefits typically show in 2–3 weeks, with full saturation around week 4.
Loading
No loading phase required. A standard 3g daily serving reaches saturation without GI discomfort or water-weight spikes.
Caffeine and creatine are the two most evidenced performance aids in sport, and almost nobody doses them together properly. 80mg — espresso strength — lifts alertness and power output without the jitters, while 4g of creatine does the long-term work underneath.
