We use a unique blend of three different forms of caffeine, including Infinergy. The other two sources include Caffeine Citrate and Caffeine Anhydrous. This gives a very well-rounded feel to the formula and creates an extended release effect. Immediate, moderate and a slow-release sources allows KXR to give you the boost and energy you need for hours with ZERO crash.

Citrulline malate has been shown to improve muscular endurance, reduce muscle fatigue, and increase blood flow. Citrulline malate works by increasing the production of nitric oxide, which leads to vasodilation and improved blood flow. Additionally, the malic acid component of citrulline malate may help to buffer lactic acid, which can improve endurance and reduce fatigue during exercise.

Beta-alanine is a non-essential amino acid that is produced naturally in the body. It helps to increase the levels of carnosine in muscles, which can reduce fatigue during high-intensity exercise and improve overall performance. For those who train, beta-alanine can help to delay the onset of muscle fatigue and improve endurance.

Hydromax Glycerol works by increasing the amount of fluid within the muscles, which can lead to improved endurance and reduced fatigue during exercise. Additionally, Hydromax Glycerol helps to improve blood flow, which can further enhance muscle pumps.
