Legion Pulse Pre-Workout
by Legion Athletics
"Mike Matthews' science-based pre-workout with 8g citrulline, 350mg caffeine, and zero proprietary blends"
Overview
Legion Pulse is the pre-workout from Mike Matthews, author of 'Bigger Leaner Stronger' and founder of Legion Athletics. The formula is built entirely on peer-reviewed research with clinical doses: 8g L-citrulline malate (the highest in any mainstream pre-workout), 3.6g beta-alanine, 2.5g betaine, 350mg caffeine, and 300mg alpha-GPC. Legion's philosophy is 'every ingredient at its clinically effective dose or it doesn't go in.' The brand publishes all research citations on their website and uses zero proprietary blends. This is the pre-workout for evidence-based fitness enthusiasts.
