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.

Our Verdict

9.0/10 — Excellent

Legion Pulse is the most scientifically rigorous pre-workout available. The 8g citrulline malate is industry-leading, and every ingredient is at its clinically effective dose. The 350mg caffeine is aggressive — start with half a scoop. For evidence-based athletes, this is the gold standard.
