L-CITRULLINE One of the keys to a great workout is a great pump. The amino acid L-Citrulline contributes to your body’s production of nitric oxide, a vasodilator. When your blood vessels are dilated, your body is more effectively able to circulate oxygen and other performance-maximizing nutrients to working muscles
L-LEUCINE The amino acid L-Leucine is known as a trigger for muscle protein synthesis (aka muscle growth) and a fuel source for your hard-lifting muscles. Your body cannot make L-Leucine, so it must come from supplements or food.
Beta-alanine acts as a buffer between fatigue-promoting lactic acid and your muscles by producing carnosine, which keeps lactic acid in check during intense workouts. That means better muscular endurance, more energy for high-intensity or explosive movements, and better overall workout performance
Caffeine is one of the most common pre-workout ingredients because it works. Supplementing with caffeine has been shown to increase focus and improve workout performance, allowing you to dig in and get the work done
