Product details
Where this label sits
Legion Pulse Stim-Free sits in the stim-free tier of the Scoop Sense pre-workout database, which spans 0–400 mg of caffeine per serving. Every active ingredient on the panel is listed with its own dose — nothing is hidden inside a blend total. It runs 21 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of July 2026 — never from the marketing page.
Key ingredients & studied doses
- Citrulline Malate · 8 g. Within the 6–8 g range used in most citrulline studies.
- Beta-Alanine · 3.6 g. In the studied range — tingles happen even without caffeine.
- Alpha-GPC · 300 mg. A choline compound studied for focus during exercise.
Flavors & sweetener
Same stevia-sweetened flavor family as regular Pulse.
Who it's best for
People who train late in the day or want zero caffeine — the effects here come from the non-stimulant ingredients. Derived from the label figures above — not medical advice.
How we log this label
Every entry is built the same way: we read the current supplement facts panel, log each disclosed dose, compare it against the amounts used in published research, flag proprietary blends, and state the cautions plainly. The full methodology explains each step.
This label against the research
How we evaluate labelsEach bar shows the amount commonly used in published human research, and where this label's dose falls against it. Research amounts are context, not a recommendation — they are not doses, and nothing here is medical advice.
-
Citrulline8 g
At or above the studied amount0studied range 6 g–8 g10 g
Studies use about 6 g of pure L-citrulline, or 8 g of citrulline malate — which is about 5.3 g of citrulline at the usual 2:1 ratio, and closer to 4 g if the label is 1:1.
Source: Gough et al., European Journal of Applied Physiology 2021 — “The most commonly employed dose of CM is a single acute 8 g dose”
-
Beta-alanine3.6 g
At or above the studied amount0studied range 3.2 g–6.4 g7 g
Studied as a daily loading protocol of 3.2–6.4 g taken for four weeks or longer. A single serving below that range still counts toward the daily total, but one scoop is not a studied dose on its own.
Source: Rezende et al., Frontiers in Physiology 2020 — “It seems that substantial amounts of BA are required to increase MCarn, with most studies using doses of ~3.2–6.4 g·day−1, for periods ranging from 4 to 24 weeks.”
-
Alpha-GPC300 mg
At or above the studied amount0studied range 300 mg–600 mg700 mg
Studied at 300–600 mg before exercise, with most trials at about 600 mg; the evidence base is small compared with caffeine or creatine.
Source: Marcus et al., Journal of the International Society of Sports Nutrition 2017 — “The majority of studies use doses of around 600 mg in an acute fashion”
Common questions about Legion Pulse Stim-Free
Is Legion Pulse Stim-Free really caffeine-free?
The label lists 0 mg of caffeine. It is still an active formula — ingredients like Citrulline Malate and Beta-Alanine are dosed to have effects — so read the full label rather than treating stim-free as effect-free.
Why does Legion Pulse Stim-Free make my skin tingle?
The 3.6 g of beta-alanine. The prickling (paresthesia) in the face, neck, and hands is generally considered harmless, is dose-dependent, and fades on its own — typically within about an hour. Most beta-alanine studies use 3.2 g per day.
Does Legion Pulse Stim-Free disclose every dose?
Yes — the label lists an individual amount for each ingredient, with no proprietary blends. That is what the "label fully disclosed" tag on Scoop Sense means, and it is what lets each dose be compared against the amounts used in published research.
