Centurion Labz Blood Rush Lemon Ice is a stimulant-free pre-workout supplement formulated to enhance muscle pumps and blood flow during your workout. The key ingredients include Norvaline, Hydromax (glycerol), L-Arginine, Citrulline Malate, and Beet Root Extract, which work synergistically to maximize nutrient delivery and hydration to the muscles. Blood Rush Lemon Ice is best taken 15-20 minutes before your workout to experience the full effects. For longer or more intense training sessions, you can try drinking half the serving pre-workout and the other half intra-workout to prolong the pump.
