Do you need a long lasting energy supply that aids not only in maintaining maximum intensity to the very end of your workout, but also decreases recovery times dramatically? The unique and patented ingredients in Endur-O2 are proving to be the supplement industry's "next big thing". Endur-O2 utilizes the aerobic aid citrulline malate that has shown to sustain ATP levels well past the anaerobic stage where creatine benefits stop. Additionally, several clinical studies report that citrulline malate may also increase nitric oxide (NO) production more efficiently than the commonly accepted "nitric oxide precursors". A nitric oxide insurgence of substantial magnitude may not only offer continuous fuel for the muscle to keep you on the bike, treadmill or stepper but also add repetitions to your resistance training by reducing the burn of lactic acid build-up. Endur-O2 is additionally fortified with the US Government patented super creatine called Kre-Alkalyn®. Nearly 100% absorbable with virtually no water retention or bloating, Kre-Alkalyn® makes Endur-O2 the ultimate supplement for the athlete looking to push their workouts past the natural limits that formerly dictated fitness goals.240 Capsules Supplement Facts Serving Size4Capsules Servings Per Container60Amount Per Serving % DVCitrulline Malate 2600mg ** Kre-Alkalyn®(Buffered Creatine US Patent #6,399,661) 400mg *** Equivalent to 4 grams of Creatine powder. ** Percent Daily Values not currently considered essential.Other Ingredients Magnesium Stearate, GelatinDirections: Take four capsules twice daily.
