Six Star
Pre-Workout Explosion 2.0
Our analysis — editorial take, not from the label
The 2.0 relaunch drops the old proprietary blend and prints a number beside every ingredient — then advertises the doubles. Every figure on the front of the tub is two scoops; the panel's own serving is one 10 g scoop at 160 mg caffeine, 1.6 g beta-alanine and 1.5 g citrulline, all under their studied amounts. Doubling reaches the beta-alanine and betaine research amounts and halves the tub.

Cautions
- The 320 mg caffeine, 3.2 g beta-alanine and 3 g citrulline on the front of the tub are two-scoop figures, footnoted 'Per 2 Servings' — the Supplement Facts panel's own serving is one 10 g scoop, at half of each
- The directions escalate: one scoop to assess tolerance, then two scoops before a workout, capped at two servings in 24 hours — so a 30-serving tub is 15 workouts at the dose the front of the tub advertises
- Beta-alanine tingling (harmless skin prickling) is likely at the two-scoop dose, where beta-alanine reaches 3.2 g

Product details
Where this label sits
Six Star Pre-Workout Explosion 2.0 sits in the moderate 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 30 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
- Caffeine Anhydrous · 160 mg. Below the 200-400 mg used in most caffeine performance research, and there is no theanine on the panel to pair with it. The 320 mg on the front of the tub is two scoops, which the directions escalate to after the first.
- Beta-Alanine · 1.6 g. Half the 3.2 g/day floor used in most beta-alanine research; the studied amount arrives only at the two scoops the directions build up to, and tingles are likely there.
- L-Citrulline · 1.5 g. A quarter of the 6-8 g used in most citrulline pump studies, and still under half of it at the two-scoop dose.
- Betaine Anhydrous · 1.25 g. Half the 2.5 g used in most betaine power-output studies; two scoops reach it.
Flavors & sweetener
Four flavors (Fruit Punch, Grape, Icy Rocket Freeze, Pink Lemonade) sweetened with sucralose alone and colored with FD&C Red No. 40 and Blue No. 1 rather than fruit or vegetable sources.
Who it's best for
Most regular gym-goers — the caffeine dose is in the range of about two cups of coffee. A reasonable pick when cost per serving matters. 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.

Caffeine160 mg
80% of the low end of the studied range0studied 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.”
-
Beta-alanine1.6 g
50% of the low end of the studied range0studied 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.”
-
Citrulline1.5 g
25% of the low end of the studied range0studied 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.

-
Betaine1.25 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.

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 Six Star Pre-Workout Explosion 2.0 make my skin tingle?
The 1.6 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 Six Star Pre-Workout Explosion 2.0 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.
