BSN N.O.-XPLODE Pre-Training Performance Powder – Green Apple – 2.45 lbs The Original Pre-Workout Igniter. Re-engineered. In 2004 BSN® changed the landscape of sports nutrition forever when we introduced the first complete pre-workout supplement, N.O.-XPLODE®. BSN® pros have been hard at work over the past year to deliver the next evolution of pre-workout supplements. We talked to supplement users, heard the feedback, and crafted a formula designed to help deliver explosive energy, enhanced endurance and maximum performance through our new Master Performance Blend. We also took our work one step further and enhanced the taste, ensuring the new N.O.-XPLODE® delivers on the BSN® promise of great taste and superior mixability.
