Set 1 ("Andro Stimulation"): Purpose: Support the naturally occurring testosterone response to exercise and amplify it to support a more anabolic response. The Andro Stimulation also further enhances the "Pump" response to exercise. Set 2 ("Neuro-Emotive Energy"): Purpose: Support overall neurological performance and motivation by enhancing cognitive function and decreasing the muscular pain associated with exercise. Will also enhance and sustain energy levels during exercise without overstimulation or a drop off in performance. Set 3 ("Nitric Oxide"): Purpose: Increase nitric oxide (NOX) levels, blood flow and dilation/volumization of cardiovascular and muscular tissues; improve quality of pumps (faster onset, harder). Set 4: ("Strength-Endurance"): Purpose: Enhance strength and power levels (increasing 1 rep maximum). Also boosts endurance by reducing blood lactates to increase your abili8ty to perform multiple repetitions. The formula is designed to maximize power output while minimizing water retention. Set 5 (Anabolic Solidification"): Purpose: Increase protein synthesis; enhance exercise-induced muscle hypertrophy; increase muscle size and hardness.
