How they differ in real use

Both the Legion Pulse Pre-Workout and the PEScience Prolific Pre-Workout made our Top 5 Pre-Workout Supplements, at #3 and #5. The best overall balance of evidence and quality control. Clinically dosed (8g citrulline, 3.6g beta-alanine, 350mg caffeine), Labdoor certified with published COAs, made in an NSF-certified cGMP facility. The cleanest tingle-free pick. At its full 2-scoop serving—6g citrulline, 320mg caffeine, theanine, citicoline—it's a coherent energy/focus/pump formula with published COAs, though it omits beta-alanine.
