Enter With Purpose provides plenty of stamina to push through long workouts thanks to the inclusion of Beta-O (Beta Alanine Orotate) dosed at 2.5 grams and COP (Creatinol-O-Phosphate) dosed at 500mg per serve. The unique combination of beta alanine and orotic acid in Beta-O serves to buffer lactic acid whilst simultaneously boosting carnosine levels, providing enhanced performance, increased endurance and elevated exercise capacity during long duration workouts. The primary action of creatinol-o-phosphate is to prolong anaerobic glycolysis in the presence of excess lactic acid. Creatinol-O-Phosphate acts by overriding the mechanism of excess lactic acid accumulation by acting as an intracellular buffer, preventing a dramatic drop in pH and allowing muscle contractions to continue beyond the point at which they would normally shut down. Hence, Creatinol-O-Phosphate works in conjunction with Beta-O to increase muscular endurance. In addition, 1 gram of Betaine Anhydrous works to improve muscle strength and power, primarily through boosting muscle protein synthesis.

Backing up the impressive stamina blend, Enter With Purpose delivers 1 gram of Agmatine Sulfate and 600mg of Beta Vulgaris to increase nitric oxide production and support enhanced blood flow, nutrient delivery and long lasting muscle pumps. One criticism of EWP is the omission of Citrulline Malate to further enhance nitric oxide production and reduce fatigue. However for best results EWP can be taken with Run Everything Labs' pre-workout pump formula STW Show The World (containing 2.5 grams of Citrulline Malate and an additional 1 gram of Agmatine Sulfate) which enhances the effects of the nitric oxide boosting ingredients found in EWP.

In terms of its stimulatory effect, Enter With Purpose hits hard, boasting 300mg of Caffeine per serve to provide very strong physical energy to maximize training output. Surprisingly the "jitters" side-effect typically associated with higher stimulant pre-workout supplements is very minimal when using EWP and there is little to no harsh post-workout energy crash. The inclusion of Taurine in a 1 gram dose provides additional synergistic effects promoting greater concentration, alertness and an overall sense of well-being.

Finally, and arguably of most interest, is the 305mg "EWP Blend", a proprietary mix of Theobromine, Synephrine HCL and Arco Fuel (Arecoline Hydrobromide 98%) that works synergistically to increase energy, enhance mental focus, boost metabolic output and improve mood. Synephrine increases both energy and metabolic rate via adrenergic receptors in the brain, providing increased lipolysis and energy without the associated increases in heart rate that can cause the "jitters". Arecoline Hydrobromide and Theobromine stimulate various psychoactive mechanisms, crossing the blood-brain barrier and delivering some of the most intense mental focus ever experienced while using a pre-workout supplement.
