Highly promoted and proprietary arginine formula is considered an industry standard and for good reason. Provides strong nitric oxide-inducing substrates that require little conversion to induce rapid nitric oxide release. Evogen is using a HUGE dose of this to give you extreme vasodilation and pumps like you've never experienced before. Although many brands still use citrulline malate, Evogen has chosen to use a high dose of pure citrulline due to its superior results. This was not a cheap decision and the difference in results within this formula is unmatched. Not only does pure citrulline help boost nitric oxide levels, it also helps flush out exercise-induced toxins and waste products like ammonia. In fact, you feel more refreshed after a workout because of this, and it's key to the success of this formulation. Quantity: 480 gr. Flavor: Sour Watermelon.
