Legion Pulse Stim-Free is a caffeine-free pre-workout with disclosed ingredient amounts. Bucked Up also sells Non-Stimulant Pre-Workout and PUMP-OCALYPSE. The useful comparison is the serving-level formula, not which brand sounds more intense. This is a label review, without firsthand taste or workout claims.
Legion Pulse Stim-Free
The current manufacturer page lists 8 g citrulline malate, 3.6 g beta-alanine, 2.5 g betaine and 300 mg Alpha-GPC powder standardized to 50% per serving. That last ingredient corresponds to 150 mg active Alpha-GPC, not 300 mg of pure active ingredient. Compare the serving directions on your tub because scoop sizes and packaging can vary.
Beta-alanine’s studied benefits depend on regular use; an immediate tingle is not proof of improved training. Citrulline findings are mixed, and a higher headline gram number does not establish that one complete formula will outperform another.
Bucked Up Non-Stim and the older Zero links
The older Bucked Up Zero destination is currently unavailable. The legacy stim-free product link (unavailable) is retained here for reference. It should not be treated as a working purchase page.
The current Bucked Up Non-Stim listing describes a caffeine-free formula with 6 g citrulline malate 2:1, 2 g beta-alanine and 200 mg AlphaSize Alpha-GPC 50%, corresponding to 100 mg active Alpha-GPC. Those details describe the current Non-Stim product, not verified inventory at the older URL.
PUMP-OCALYPSE is a different formula
PUMP-OCALYPSE is also caffeine-free. Its listed serving includes 3.5 g HydroPrime glycerol powder at 65% yield, 3 g L-citrulline, 1 g PeakO2, 1 g arginine HCl, 500 mg agmatine sulfate and 500 mg betaine. The glycerol-powder weight is not the weight of pure glycerol.
The PUMP-OCALYPSE label and directions are more useful than assuming it provides the same ingredients as Pulse or Non-Stim. Its current ingredient list does not include beta-alanine. No head-to-head trial is presented here to rank its pump effects above Legion.
A practical decision
Compare the ingredients you want, total servings, sweeteners and final cost. The older Zero link remains unavailable; use the current manufacturer reference above for Non-Stim facts. Review PUMP-OCALYPSE separately if its different ingredient mix interests you.
Caffeine-free does not mean appropriate for every medical condition, medication or pregnancy. Follow the product warnings and get professional advice where needed. Avoid casually combining several formulas with overlapping ingredients.
The Bucked Up promotion link and offer terms do not establish a guaranteed 20% discount. Likewise, check the sample kit listing and current kit contents and cost rather than assuming a particular caffeine-free product is included.
