Since its launch in 2013 as a category-defining pre-workout pump additive, Purus Labs NOXygen has remained unrivaled. For a smooth and long-lasting energy release, full doses of beta amino acid, VitaCholine natural choline bitartrate, and a special blend of ZumXR extended-release and anhydrous caffeine are now combined with NO3-T citrulline nitrate and Hydromax powdered glycerol, the cornerstones of NOXygen.
