🧪 Formulation Notes

Purus Labs NOXygen has remained unmatched since its inception in 2013 as a category-defining pre-workout pump additive. N03-T Citrulline Nitrate, combined with HydroMax a powered glycerol- the cornerstone of NOXygen - are now combined with full doses of beta alanine, Vitacholine natural choline bitartrate, and a unique blend of caffeine anhydrous and zumXR extended-release caffeine for smooth, sustained energy release. Rounded out by L-tyrosine and Huperzia serrata for focus and pink Himalayan sea salt for hydration, NOXygen PreWorkout is formula finally worthy of the NOXygen name.
