FAQ
What exactly is DUUS Energy+ gel?
DUUS Energy+ gel is a liquid pre-workout in individual sachet format, designed to be consumed in three seconds without water or preparation. Formulated with maple syrup and certified by Health Canada (NPN), it contains a combination of active ingredients — caffeine, L-Citrulline, Beta-Alanine, Taurine, and B vitamins — to support energy, endurance, and focus during intense workouts.
What is the difference between DUUS Energy+ and a classic powdered pre-workout? The main difference is the format and absorption speed. DUUS gel is consumed directly, without water, in three seconds, allowing for faster absorption of active ingredients than powders dissolved in water. Additionally, DUUS uses a natural maple syrup base rather than refined sugars, and its formula is precisely dosed to avoid the overstimulation and energy crash effects often associated with highly concentrated pre-workouts.
How much caffeine does each gel contain?
Each DUUS Energy+ gel contains 100 mg of caffeine, which is approximately equivalent to a strong cup of coffee. This dosage is calculated to produce a rapid and sustained activation of the nervous system without causing excessive nervousness or a sudden energy drop at the end of a workout.
What are all the medicinal ingredients in DUUS Energy+ gel?
The medicinal ingredients are: L-Citrulline (3g), Beta-Alanine (2.6g), Taurine (1g), L-Arginine (0.5g), Caffeine (100mg), Potassium (100mg), Niacinamide — vitamin B3 (16mg), Pyridoxine hydrochloride — vitamin B6 (5mg), Cyanocobalamin — vitamin B12 (0.8mg). Non-medicinal ingredients are: Distilled water, Maple syrup, Himalayan salt, Natural flavors, Carrageenan, Agar-agar, Sodium benzoate, and Potassium sorbate.
Why is Beta-Alanine included in the formula?
Beta-Alanine is an amino acid that helps buffer lactic acid in muscles during intense efforts, which delays the onset of muscle burn sensation. Scientific studies indicate a measurable improvement in resistance to muscle fatigue with regular supplementation, particularly during high-intensity efforts such as CrossFit, HYROX, or weightlifting.
What is L-Citrulline used for in DUUS gel?
L-Citrulline Malate 2:1 promotes nitric oxide production in the body, which improves vasodilation and blood flow to active muscles. Concretely, this leads to better muscle oxygenation, increased endurance during prolonged efforts, and faster recovery between sets. Studies have shown an improvement in anaerobic performance of up to 9% with L-Citrulline supplementation.
Does DUUS Energy+ gel contain sugar?
It contains maple syrup, which is a natural source of rapidly absorbed sugars (mainly sucrose). It does not contain added refined sugars or artificial dextrose. Maple syrup is specifically chosen for its ability to provide quickly available energy without causing an excessive glycemic peak.
Is the gel vegan and gluten-free?
DUUS Energy+ gel does not contain animal-derived ingredients in its medicinal formula or main ingredients. For individuals following a strict vegan diet or suffering from specific food intolerances, we recommend consulting the complete list of ingredients on the packaging or contacting our team for confirmation adapted to your situation.
Why do I feel a tingling sensation after taking the gel?
This skin tingling, called paresthesia, is a normal and harmless side effect of Beta-Alanine. It typically occurs on the face, neck, arms, and hands, and lasts between 15 and 45 minutes depending on your individual sensitivity. This effect tends to decrease with regular use as the body adapts. It simply confirms that Beta-Alanine is present in an effective amount in the formula.
Can DUUS Energy+ gel be taken by women?
Absolutely. The DUUS Energy+ formula is designed for any healthy adult athlete, regardless of gender. The dosages are adapted for general sports use. Pregnant or breastfeeding women should, however, avoid this product due to its caffeine content, as is the case for any supplement containing stimulants.
USE & PERFORMANCE
When should I take the gel relative to my workout?
The ideal time is 10 to 15 minutes before the start of your workout or competition. This allows caffeine and amino acids to reach their optimal concentration in the blood when you need them most — right from the first few minutes of effort.
Can I take the gel on an empty stomach, before breakfast?
Yes. The gel format and maple syrup base make it easy to consume on an empty stomach without significant digestive discomfort. If you are particularly sensitive to caffeine on an empty stomach, start by testing the gel with a small, light snack during your first uses.
How many gels can I take per day?
We recommend not exceeding one gel per workout session and a maximum of two gels per day, so as not to exceed the recommended caffeine intake. If you have two sessions in the same day, observe an interval of at least four to six hours between the two intakes to maintain your caffeine tolerance and preserve your sleep quality.
How long do the effects of DUUS Energy+ gel last?
The effects of caffeine generally last between 3 and 5 hours depending on your individual metabolism, caffeine tolerance, and hydration level. The effects of L-Citrulline on blood circulation are generally felt throughout the duration of the workout. Beta-Alanine, for its part, acts cumulatively with regular use over several weeks.
Do I need to take water with the gel?
No, it's not necessary. The gel is consumed directly from the sachet without water. That said, maintaining good overall hydration before, during, and after exercise is always good practice, regardless of taking the gel.
Can I take DUUS gel in the evening before a late workout?
If your workout ends less than 4 to 6 hours before your usual bedtime, the caffeine in the gel could affect your sleep quality. In this case, it is preferable to adjust the intake schedule or consult our team for personalized advice based on your caffeine sensitivity.
How can I maximize the effects of Beta-Alanine?
Beta-Alanine is a cumulative ingredient whose effects on muscular endurance gradually accumulate in the muscle with regular supplementation. To maximize its benefits, it is recommended to consume the gel daily, even on non-training days, and maintain this regularity for a period of at least 4 weeks to observe a noticeable improvement in fatigue resistance.
Is DUUS Energy+ gel suitable for official competitions?
The gel is certified by Health Canada (NPN) and formulated with ingredients widely used in sports nutrition. If you are subject to a specific anti-doping program (high-level sport, national or international federated competitions), it is recommended to check the complete list of ingredients with your sports doctor or federation before any use in competition.
Can I mix DUUS gel with water or a sports drink?
Although the gel is designed to be consumed directly, there is technically nothing to prevent you from diluting it in water or an isotonic drink if you prefer to consume it in liquid form. Note, however, that this method will slightly slow down the absorption of the active ingredients compared to direct consumption.
Can DUUS Energy+ gel be used during exercise, not just before?
The gel is primarily formulated as a pre-workout, but some athletes performing very long efforts (more than 90 minutes) also use it during exercise for an energy boost. In this case, pay attention to your total caffeine intake over the day and make sure you stay well hydrated.
FLAVORS & PRODUCTS
What flavors are available in the DUUS Energy+ range? The DUUS Energy+ range is available in four options: Cherry (intense and distinct flavor), Pink Lemonade (light and fruity flavor), Green Apple (vibrant and refreshing flavor) and the Mixed Box which combines all three flavors in 12, 24 or 48 gel formats. A new Summer Flavors is also available as a limited edition.
Which flavor do you recommend to start with? If this is your first time with DUUS Energy+ gel, the Mixed Box is the ideal option as it allows you to test all three flavors and determine your favorite before ordering in bulk. If you prefer to start with a single flavor, Pink Lemonade is generally the most accessible and versatile for a first experience.
Is there a performance difference between the flavors? No. The three flavors — Cherry, Pink Lemonade, and Green Apple — share exactly the same medicinal formula with identical dosages for all active ingredients. Only the natural flavors differ. The choice of flavor is therefore entirely a matter of personal preference.
Are the flavors very sweet? DUUS gels are sweetened with maple syrup, which provides a natural and balanced sweetness without being excessive. The sweetness level is generally described as moderate and pleasant, far from the very artificial flavors often associated with sports supplements. Green Apple tends to be slightly more tart, while Cherry and Pink Lemonade are perceived as sweeter.
Does the Mixed Box contain an equal number of gels of each flavor? The Mixed Box is evenly distributed among the three available flavors. For a box of 12 gels, you will receive 4 gels of each flavor. For 24 gels, 8 of each. For 48 gels, 16 of each. If you have a particular preference for a flavor, you can also order single-flavor boxes.
