Why do I need a pre-workout supplement?
Serious formulas such as XS™ Pre-Workout Boost, deliver: (1) extra energy to help you power through workouts, and (2) ingredients that help you perform better by fighting fatigue and boosting endurance.

What are the benefits of a pre-workout?
It depends on the ingredients used and the doses of those ingredients. A good pre-workout will provide you with improved focus, increased energy, reduced fatigue and support muscular endurance and performance.

What’s unique about XS™ Pre-Workout Boost supplement?
This formula has been intentionally designed to boost your training performance and thus help you achieve your muscle and strength goals. It utilizes science-based ingredients including clinical doses of L-citrulline and beta alanine to ensure you are getting the most of your workouts. Main ingredients include L-citrulline and Carnosyn®** Beta Alanine, which has been shown to boost nitric oxide and muscle pump for improved muscle endurance during exercise/workouts.  It also includes Caffeine, Rhodiola Rosea and L-Theanine to improve your alertness and energy levels without the caffeine jitters. Lastly, it has a mega dose of B-vitamins to help you support energy production from your food.

Why are amino acids included in this formula?
Amino acids are essential in building and repairing muscle fibers and with intense and prolonged exercise we lose amino acids in the process. XS Muscle Multiplier* amino acid blend has been included to help start replenishing lost amino acids from your training.

How much caffeine is in the formula?
This product contains 115 mg of natural caffeine per serving, about the amount in a cup of coffee. The formula in XS™ Pre-Workout Boost supplement is a balanced, high-quality formula without the extra caffeine. To learn more about caffeine take a look at this article; Caffeine in Energy Drinks: how much is too much?

Is XS Pre-Workout Boost supplement naturally sweetened?
Yes! It is sweetened with Stevia®**. In fact, it is not only naturally sweetened with Stevia, but it also contains no artificial colors, flavors, or preservatives. This is a quality, clean formula to support your training.

When is the best time to take a pre-workout?
Consume a serving of XS Pre-Workout Boost supplement 15-30 minutes prior to your resistance working sets! Caffeine has a half life of about 4-6 hours therefore it is best to take it prior to working out and 4-6 hours before bedtime.

Is it safe to take a pre-workout daily?
For a healthy adult it is safe to regularly take a pre-workout, however we recommend speaking with your physician if you have any concerns or medical conditions. We recommend taking a pre-workout prior to engaging in intense anaerobic exercises, which in a well programmed routine, can be equivalent to 3-6 times a week.

Can men and women benefit from a pre-workout?
Absolutely. More now than ever, men and women are seeing the benefit of improving their strength and muscle endurance, and a pre workout can elevate your training and help you obtain the results you’re looking for. Whether it is strength or improved performance, XS Pre-Workout Boost can assist in the training.

Is a tingling sensation common?
In some individuals, consumption of niacin (also known as vitamin B3 and nicotinic acid) may cause flushing of the skin that is generally mild. In addition, consumption of beta-alanine may cause a tingling or prickling sensation of the skin. In both cases, the effect is usually temporary.

Why is a signature and proof of age required for this product and not others?
New York law imposes the requirements for certain dietary supplements making “weight loss” or "muscle building" claims. Only those products making these claims require a signature and age verification upon delivery. For states with these mandates, products will also be charged an additional fee. This fee covers additional order handling costs and will be shown in your cart at checkout. LEARN MORE
