Bulk and Pulse start from the same pump base — both run 8g citrulline malate and 2.5g betaine — so the raw pump foundation is close. Where they split is everything around it.
Pulse is deliberately concentrated: 350mg caffeine, 350mg theanine, 3.6g beta-alanine and 300mg AlphaSize material, and that's essentially the formula. It's narrow. Bulk takes the opposite approach — 200mg caffeine, 4g beta-alanine, plus tyrosine, taurine, theobromine, SenActiv, BioPerine and electrolytes — so it covers more of the workout at a more moderate stimulant load.
The other practical gap is servings: Bulk gives 30 full servings to Pulse's 20. For a daily driver that adds up.
Bulk: start with half a scoop, then move to one full scoop, taken 20–30 minutes before training. Count caffeine from other sources.
Legion Pulse: start with one scoop, which is half the full serving. Use two scoops (350mg caffeine) only once the lower amount is tolerated, 15–30 minutes before training.
Bulk is the better choice for most lifters. It gives up stimulant intensity but adds a broader performance, hydration and focus formula while providing ten more full servings.
Pulse is the better specialist choice for someone who wants 350mg caffeine without exotic stimulants. It's not badly dosed — it's simply narrower and much more stimulant-heavy.
