Pumpsurge
Our analysis — editorial take, not from the label
A caffeine-free label that prints a number for every ingredient and then splits each one across two columns. The 8 g citrulline, 2.5 g betaine and 2 g GlycerSize on the front of the tub all carry a 'per 2 scoop serving' footnote, so the working dose is 16.7 g and the tub's own '30 servings' count is single scoops.

Cautions
- The 8 g citrulline, 2.5 g betaine and 2 g GlycerSize printed on the front of the tub are two-scoop figures — the panel prints a one-scoop column at exactly half of each
- The '30 servings' on the same tub counts single scoops, so at the full two-scoop serving a container is 15 workouts
- The back-panel directions read 'mix one serving (1 scoop)' while the icons beside them say 1-2 scoops — the label points two ways

Product details
Where this label sits
Jacked Factory Pumpsurge 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 15 servings per container at the full labeled serving. Everything on this page comes from the manufacturer's supplement facts panel as of September 2026 — never from the marketing page.
Key ingredients & studied doses
- L-Citrulline · 8 g. At the full two-scoop serving this sits at the top of the 6-8 g range used in most L-citrulline pump studies; the one-scoop column is 4 g, which is under it.
- Betaine Anhydrous (BetaPure) · 2.5 g. Matches the 2.5 g amount used in most betaine power-output studies, but only at two scoops — one scoop is 1.25 g.
- GlycerSize (65% Glycerol Powder) · 2 g. About 1.3 g of actual glycerol, far under the roughly 1 g per kg of body weight used in glycerol hyperhydration research; a muscle-fullness dose rather than a hydration-loading one.
- L-Tyrosine · 1 g. Below the roughly 7-14 g acute amounts (100-150 mg/kg) used in most tyrosine cognitive-stress research.
Flavors & sweetener
Only two flavors, Strawberry Lemonade and Cherry Limeade, sweetened with sucralose plus acesulfame potassium and colored with beet root powder rather than artificial dye.
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. The bars compare what the label states; we do not laboratory-test the product to confirm it.
-
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.

-
Betaine2.5 g
At or above the studied amount0studied range 2.5 g3.5 g
Trials run from 1.25 g to 5 g a day; 2.5 g, usually split into two doses, is the amount most of them use.
Source: Lee et al., Journal of the International Society of Sports Nutrition 2010 — “Betaine supplement (B) was given as 1.25 grams (g) of betaine (Danisco Inc., Ardsley, NY) in 300 mL of Gatorade© sports drink, taken twice daily”
-
Glycerol2 g
Hyperhydration research doses glycerol by body weight — about 1.0–1.2 g per kg, roughly 70–84 g for a 70 kg athlete, taken with a litre or more of fluid before exercise. Pre-workout labels carry a few grams — the highest on file here is 4 g — which is far below any studied hyperhydration amount, and branded powders are usually 65% glycerol by weight, so check which figure the label states.
Source: van Rosendal et al., Sports Medicine 2010 — “endurance athletes intending to hyperhydrate with glycerol should ingest glycerol 1.2 g/kg BW in 26 mL/kg BW of fluid over a period of 60 minutes”
-
L-tyrosine1 g

Trials that report an effect generally use 2 g or more, and often far more relative to body weight than a pre-workout scoop provides.

Common questions about Jacked Factory Pumpsurge
Is Jacked Factory Pumpsurge really caffeine-free?
The label lists 0 mg of caffeine. It is still an active formula — ingredients like L-Citrulline and Betaine Anhydrous (BetaPure) are dosed to have effects — so read the full label rather than treating stim-free as effect-free.
Does Jacked Factory Pumpsurge 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.
Do the numbers for Jacked Factory Pumpsurge assume one scoop or two?
All figures on this page are per full labeled serving. The 8 g citrulline, 2.5 g betaine and 2 g GlycerSize printed on the front of the tub are two-scoop figures — the panel prints a one-scoop column at exactly half of each.
