      Got questions?

      How safe are pre-workout supplements?

      Pre-workout supplements often contain ingredients like caffeine, beta-alanine, and various amino acids. While these can be effective, excessive amounts or interactions with other medications can cause side effects. We recommend taking ½ scoop of Blast X for first-time users to evaluate tolerance.

      Is this pre-workout suitable for both men and women?

      Most pre-workout supplements are designed to work for both men and women, however, the key is to look at the ingredients and make sure they align with your personal goals and health needs. Some supplements might have higher doses of stimulants or other ingredients that might be more intense, so it’s worth checking if they suit your comfort level and any specific health considerations you might have.

      What do pre workout supplements contain?

      Ingredients can differ depending on the brand’s formulation, but our Blast X advanced pre workout specifically features caffeine, beta-alanine, and L-citrulline as its key components. These ingredients work synergistically to enhance energy, endurance, and overall workout performance. Their popularity stems from their ability to address various aspects of exercise, making your workouts more effective and enjoyable.

      Is pre-workout the same as protein powder?

      No, pre-workout and protein powder are not the same. Pre-workout supplements are designed to boost energy, focus, and performance during exercise. They usually contain ingredients like caffeine, beta-alanine, and citrulline, and are taken before your workout. On the other hand, protein powder is used to increase protein intake and support muscle recovery. It's often mixed into shakes or added to foods and is typically consumed after a workout. So, pre-workout is about enhancing your exercise session, while protein powder helps with recovery and muscle building.

      Can pre workout supplements cause heart problems?

      Pre-workout supplements can potentially impact cardiovascular health due to their stimulant content. High levels of caffeine and other stimulants in these products can elevate heart rate, raise blood pressure, and cause palpitations or irregular heartbeats, particularly in sensitive individuals. To mitigate these risks, we recommend consulting a healthcare professional before starting any new supplement. Additionally, beginners should start with just 1/2 scoop of Blast X to assess their body's tolerance.
