Legion is a supplement brand, and Pulse is its named pre-workout. “Legion pre-workout” does not describe every transparent-label or clinically marketed formula. This guide uses Legion’s original caffeinated U.S. Pulse information, verified October 12, 2026. It is a product-level overview, not a claim that every flavor, market or Pulse variant has an identical label.
Original Pulse’s two-scoop serving
The manufacturer information lists the following amounts for a full two-scoop serving:
- Caffeine: 350 mg.
- L-theanine: 350 mg.
- Citrulline malate: 8 g.
- Beta-alanine: 3.6 g.
- Betaine: 2.5 g.
- Alpha-GPC ingredient preparation: 300 mg, specified as 50% alpha-GPC.
One scoop provides 175 mg caffeine and half the other listed quantities. A 20-serving tub therefore contains approximately 40 individual scoops. Those are two ways to describe the same container, with different ingredient amounts per portion.
Compare ingredients on the same basis
A two-scoop headline cannot be compared fairly with another product’s one-scoop claim unless you also compare their complete servings. Reducing the amount of Pulse changes the whole formula, rather than selectively reducing caffeine. The scoop count and the gram weight printed on your chosen flavor both matter.
Keep the ingredient forms attached to their amounts. Eight grams of citrulline malate includes malate; it is not an 8 g declaration of pure L-citrulline. Similarly, 300 mg of a 50% alpha-GPC preparation is not 300 mg pure alpha-GPC. Original Pulse contains no creatine according to Legion, so do not assume it supplies creatine because that ingredient appears in other pre-workouts.
Other Pulse versions are separate formulas
Pulse Stim-Free, Pulse+ Burn and Pulse+ Pump should be assessed using their own product information. Do not carry the original caffeinated formula’s numbers into those versions. Before buying, match the complete name, caffeine status, flavor, serving definition and label on the actual container.
The verified information used here does not establish a flavor-specific scoop weight, taste ranking, mixability score or current availability. No personal testing or finished-product laboratory analysis is represented.
What the label cannot promise
The NIH exercise-supplement review distinguishes ingredient evidence from dependable results for a multi-ingredient product. Beta-alanine research generally concerns repeated supplementation, and tingling after a serving is not a measure of workout quality.
The FDA’s caffeine guidance also emphasizes individual sensitivity. Theanine does not make the caffeine disappear or guarantee freedom from sleep disruption. Include coffee, energy drinks and other supplements when reviewing total intake, follow the container’s directions, and seek professional advice about relevant medications or conditions. Choose using the verified formula and your needs rather than treating the largest labeled serving as a performance target.
