This preworkout is NOT for the weak. We packed 350mg of caffeine into every scoop, because we know that extreme workouts need extreme energy to power them. Get ready to hit that new PR. STIMUL8 HARDCORE from FINAFLEX gives you the most energy out of any pre you’ve probably tried before. 

Ever wondered how those Instagram fitness models get such amazing pumps in their pictures? It’s probably citrulline. Citrulline is an amazing ingredient for enhancing blood flow and therefore “pumps” during physical activity. L-Citrulline Malate is what powers our exclusive Hardcore Pump & Energy Matrix. It provides the most insane pumps. In every scoop of STIMUL8 HARDCORE, there is 3.9G of this Matrix formula. *
