What does 200 mg of caffeine represent in terms of coffee?

Pre Fuel contains 200 mg of caffeine — roughly the equivalent of a medium Tim Hortons coffee.

Can caffeine have an impact on sleep and recovery?

Yes, a 200mg mg dose of caffeine can disrupt sleep for some people, especially if taken later in the day. Poor sleep quality can also impact your physical recovery. We recommend taking this product at least 6 hours before bedtime, or choosing a stimulant-free version if you train in the evening.

Can I take it even if I’m new to the gym?

Yes — Pre Fuel is perfectly suitable for beginners or anyone new to using pre-workout supplements. It contains 200 mg of caffeine, which provides a solid boost of energy and focus without being too intense. It’s a well-balanced, moderate formula that can help you stay motivated, dialed in, and get more out of your workouts. 💡 Tip: If it’s your first time using a pre-workout, try starting with half a scoop to see how your body responds.

Can daily use of Pre Fuel potentially affect my natural energy levels?

Pre Fuel contains a moderate dose of caffeine (200 mg per serving) along with other stimulants. With regular use, your body may build some tolerance over time. To maintain optimal effects and keep your sensitivity to caffeine, we recommend taking a short break of 5 to 7 days after finishing each tub — or longer if you feel it’s needed.

Pre-workouts that contain Beta-Alanine often cause tingling sensations. Should I expect that?

It’s completely normal to feel a temporary tingling sensation, often around the face or arms — especially if you’ve never used beta-alanine before. These tingles are not harmful, usually fade within a few minutes, and tend to decrease over time as your body adapts. If you prefer to avoid this sensation, you can: * Start with half a scoop to assess your tolerance. * Take your pre-workout with a light meal to reduce the intensity. * We recommend Burner or Amino + Energy6 if you want stimulants without beta-alanine.

How long before a workout should I take this pre-workout?

We recommend taking it 30 to 45 minutes before your workout for best results.

Is this product made for everyone who works out?

It really depends on your training style. If your workouts involve long runs, high-intensity cardio, or sustained effort over time, a high dose of caffeine and stimulants can actually work against you. It can elevate your heart rate too much, making it harder to control your breathing and maintain steady performance. A small amount of caffeine can be helpful — but too much may reduce endurance instead of boosting it. 👉 If this is your style, we recommend Amino + Energy6. Pre Fuel is best for gym sessions focused on strength, power, or muscle pump — where you’re working in short bursts with longer rest periods between sets. 👉 If that’s your style, Pre Fuel is the right fit for you!

Can I mix it with other supplements?

Yes, absolutely. Most users combine it with EAA or creatine as part of their pre-workout routine. However, it’s very important not to combine it with other stimulant-based products, to avoid excessive caffeine or overlapping active ingredients.

Why isn’t it recommended for sports or athletic performance?

Two main reasons: 1. The very high dose of stimulants, which can elevate heart rate and interfere with performance in dynamic sports. 2. The high concentration of pump ingredients, which are great for weight training but offer little benefit — and may even hinder performance — during active sports. For athletes or sport-focused users, we recommend Amino + Energy6, a more balanced formula with moderate caffeine, essential amino acids (EAAs), and electrolytes to support endurance and hydration.

Can I take Pre Fuel on an empty stomach?

We don’t recommend it — especially if you’re sensitive to caffeine. Pre Fuel contains a high amount of caffeine, which can feel too intense when taken on an empty stomach. This may lead to side effects like jitters, nausea, or digestive discomfort. For better tolerance, we suggest taking it after a light snack or small meal, 30 to 45 minutes before your workout.

Can I take it even if I’m not going to the gym?

Technically yes, but it’s not recommended. Pre Fuel is a high-stimulant formula designed specifically for intense gym sessions. Taking it without working out could lead to overstimulation (e.g., jitters, restlessness) without any real benefit.

What are some possible effects of using Pre Fuel if you’re sensitive to stimulants or caffeine?

Pre Fuel contains 200 mg of caffeine per serving, along with other active ingredients like alpha-GPC. If you’re more sensitive to caffeine or stimulants, you might experience things like a stronger energy boost, slight jitteriness, or trouble falling asleep if the product is taken too late in the day. These effects are usually temporary and can vary from person to person. Tips if you’re sensitive: * Start with half a serving to assess your tolerance. * Avoid taking it within 6 hours of bedtime. * If you train in the evening or prefer to avoid caffeine, go for a stimulant-free formula like Pump Addict SF.

Will I experience a crash after using it?

Pre Fuel contains caffeine and other stimulants that provide a solid energy boost during your workout. For most people, there’s no major crash, especially when it’s taken before intense physical activity where the energy gets used properly. That said, everyone reacts differently. If you’re more sensitive to caffeine, you might feel a slight drop in energy a few hours later — especially if you’re sleep-deprived, dehydrated, or trained on an empty stomach. To minimize this, we recommend taking Pre Fuel with a light meal, staying well hydrated, and avoiding other sources of caffeine for a few hours afterward.

Will my product turn into a brick and clump like some other pre-workouts ?

Pre Fuel includes several highly hygroscopic ingredients, like Citrulline Malate and Alpha-GPC, which naturally absorb moisture and may clump if exposed to air or heat. To prevent clumping: * Store the product in a dry place, ideally at a stable temperature (below 25 °C) * Avoid leaving the container open or in humid environments (e.g. bathrooms or close to a dishwasher) Good to know: * Clumping is very rare — except in extremely humid conditions. * You can store the tub in the fridge to reduce clumping, but be aware this will dull the flavour intensity a bit. ⚠️ Important notice: Your car or your gym bag are VERY BAD storage spots for a pre-workout.

Can this product affect caffeine sensitivity?

Yes. Like any source of caffeine (coffee, tea, energy drinks etc.), this product can affect your sensitivity over time. Regular use may lead to a gradual tolerance. To help reset caffeine sensitivity, a break of approximately 11 days without caffeine is generally recommended, based on recent data (reference PMID: 39905628).

I loove this pre workout, I found all the products I’ve tried (4+) all made me super itchy. But this pre doesn’t do that at all! Also it being a Canadian brand made it that much easier to support.

I love having pre fuel before my workouts! Gives me the energy & push I need for a good gym sesh! The fruit punch flavor is also so good! I'm usually not the biggest fan of fruit punch because it tends to be too sweet, but this is subtle! I love BELIEVE!
