Frequently Asked Questions
What is Fuel?
Fuel is an advanced performance supplement designed for endurance athletes, trail runners and anyone pushing their limits. It combines the Performance Matrix (for energy, focus and stamina) with the Shield Matrix (for recovery, muscle protection and immune support).
When should I take Fuel?
Take 2 sachets (28 g) mixed with 500–600 ml of water about 30–45 minutes before training or racing. For long events like ultra trail runs, take an additional sachet (14 g) every 3 hours.
Can I take Fuel on an empty stomach?
No. Fuel should not be consumed on an empty stomach, as some ingredients may cause mild stomach discomfort without food.
How many servings can I take per day?
Do not exceed 5 sachets per day.
Do I still need to eat if I use Fuel?
Yes. Fuel is a supplement and not a substitute for real, nutritious food. A balanced diet remains the foundation of performance and recovery.
Is Fuel safe for everyone?
Fuel is formulated for healthy adults. If you are under 18, pregnant, breastfeeding or have a medical condition, consult your doctor before use.
How does Fuel support recovery?
The Shield Matrix (BCAAs, glutamine, HMB) helps protect muscles from breakdown, supports gut and immune health and speeds up repair after hard sessions.
Is Fuel tested for banned substances?
Fuel is developed with clean sport in mind and does not contain ingredients on the WADA prohibited list. However, professional athletes should always check with their federation or team doctor.
How does Fuel differ from an energy drink or pre-workout?
Unlike typical energy drinks or pre-workouts, Fuel is designed specifically for endurance performance. It combines performance enhancers (for blood flow, stamina, and focus) with a recovery shield (for muscle protection and repair).
Can I use Fuel every day?
Yes. Fuel can be used daily before workouts, races or on your rest days.
Will Fuel upset my stomach?
Fuel is formulated with endurance athletes in mind. When consumed with food and water as recommended, it is generally well tolerated. Avoid taking it on an empty stomach.
How quickly will I feel the effects?
Most athletes notice improved focus, energy and stamina within 30–45 minutes after drinking Fuel. Recovery benefits are more noticeable with consistent use over time.
Why do I feel tingling after taking Fuel?
The tingling sensation, known as paresthesia, is a common and harmless side effect of beta-alanine. It usually appears 10–20 minutes after consumption and fades within an hour. The intensity depends on the dose — higher single doses cause stronger tingling.
Can vegetarians and vegans use Fuel?
Yes. Fuel contains no animal-derived ingredients and is vegan-friendly.
Can I mix Fuel with other drinks?
Fuel is best mixed with water for proper absorption. You can combine it with electrolyte drinks and/or isotnoics if needed, but avoid mixing with hot beverages.
How should I store Fuel?
Store Fuel sachets in a cool, dry place, away from direct sunlight and moisture.
Does Fuel contain sugar?
No. Fuel does not contain added sugars — it’s powered by amino acids, plant extracts, and performance compounds.
Is Fuel suitable for beginners?
Yes. Whether you are a recreational runner or an elite athlete, Fuel can help improve stamina, focus and recovery.
Can Fuel help with mental focus?
Yes. Ingredients like tyrosine, ginseng and rhodiola are included to sharpen focus, improve alertness and reduce mental fatigue during long efforts.
Is Fuel suitable for women?
Absolutely. Fuel is formulated for all endurance athletes, regardless of gender. The dosage is the same for men and women.
Will Fuel make me faster immediately?
Fuel won’t replace training, but it can enhance your performance capacity — improving stamina, delaying fatigue and helping you get more out of your sessions and races.
How long does one sachet last once mixed?
Once prepared with water, Fuel should be consumed within 2–3 hours for best taste and effectiveness. Keep it refrigerated if not used immediately.
