Our analysis — editorial take, not from the label
Every dose is printed, but in two columns, and the two columns tell different stories. The 6 g citrulline, 3.2 g beta-alanine and 2.5 g betaine on the front of the tub are all two-scoop numbers; the '30 servings' claim beside them counts single scoops, which land at half of each.

Cautions
- 360 mg caffeine is the FULL two-scoop serving; the label prints a one-scoop column at exactly half (180 mg)
- The doses advertised on the front of the tub are two-scoop figures, but the '30 servings' count on the same tub counts single scoops — at label strength it is 15 workouts
- Beta-alanine tingles (harmless skin prickling) are likely at the full 3.2 g
Formulated for healthy adults — not intended for anyone under 18. Performance studies use roughly 3–6 mg of caffeine per kg of body weight, which puts 360 mg at the studied amount for a 60–120 kg adult. Full health & safety notes
Product details
Where this label sits
Jacked Factory Nitrosurge sits in the high stim 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 (Fermented) · 6 g. At the full two-scoop serving this sits inside the 6-8 g range used in most L-citrulline studies; a single scoop delivers 3 g, which is under it.
- Beta-Alanine · 3.2 g. Matches the 3.2 g/day amount used in most beta-alanine research at two scoops — expect tingles.
- Betaine Anhydrous · 2.5 g. Matches the 2.5 g amount used in most betaine studies, again only at the two-scoop serving.
- Caffeine Anhydrous · 360 mg. A high dose, paired with 180 mg L-theanine — half the caffeine amount, below the 1:1 theanine-to-caffeine ratio used in most focus research.
Flavors & sweetener

Who it's best for
Experienced high-stimulant users only — not a sensible first pre-workout. 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.
-
Citrulline6 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-alanine3.2 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.”
-
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”
-
Caffeine360 mg
At or above the studied amount0studied range 200 mg–400 mg450 mg
Performance studies most often use 3–6 mg per kg of body weight, which works out to roughly 200–400 mg for most adults. The FDA cites 400 mg a day as an amount not generally associated with negative effects in healthy adults.
Source: Guest et al., Journal of the International Society of Sports Nutrition 2021 — “Caffeine has consistently been shown to improve exercise performance when consumed in doses of 3–6 mg/kg body mass.”

360 mg per full labeled serving — roughly 3.8 small cups of coffee. Within the Scoop Sense pre-workout database (0–400 mg per serving) that places it in the high stim tier. The FDA cites about 400 mg per day as an amount generally not associated with negative effects in healthy adults, and coffee, tea, and energy drinks count toward the same total.
Why does Jacked Factory Nitrosurge make my skin tingle?
The 3.2 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 Jacked Factory Nitrosurge 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.
