How much caffeine is in The Curse pre workout?

Matched JNX Sports / UK retailer panels for The Curse! list 155 mg caffeine anhydrous per scoop (inside the Mind Control Matrix). Brand directions allow 1–3 scoops; start with one scoop to assess tolerance. Two scoops are 310 mg caffeine — stay within a sensible daily total from all sources and do not stack with other stimulants.

How much caffeine is in The Shadow pre workout?

Matched panels for The Shadow! list 350 mg caffeine anhydrous per 9 g scoop — more than double a single scoop of The Curse!. It is intended for experienced stimulant users only, not for under-18s, pregnancy or breastfeeding, and should not be stacked with other high-caffeine products.

How much caffeine is in JNX The Ripper?

Matched brand panels for The Ripper! list 200 mg total caffeine per 5 g scoop from caffeine anhydrous plus guarana seed extract standardised to 47% caffeine. That is higher than The Curse! (155 mg) and lower than The Shadow! (350 mg) on a one-scoop basis.

What flavours does The Curse pre workout come in?

Live GymStack Curse tub flavours include Blue Raspberry, Cherry Limeade, Dark Grape, Fruit Punch, Green Apple, Lemon Rush, Orange Mango, Peach Mango, Peach Rings, Pina Colada, Pineapple Shred, Sour Candy, Strawberry Kiwi, Sweet Melon, Tropical Storm and Watermelon, plus EU-labelled packs and single-serve sticks in overlapping fruit flavours.

What is the difference between The Curse and The Shadow?

Both are JNX Sports stimulant pre-workout powders. The Curse! is the original line at 155 mg caffeine per scoop with a 3,000 mg beta-alanine/creatine blend and a smaller citrulline/arginine amplifier. The Shadow! is the higher-stim option at 350 mg caffeine per scoop with disclosed citrulline, beta-alanine, taurine, betaine and leucine amounts. Choose Shadow only if you already tolerate strong caffeine doses.

Is The Curse pre workout vegan?

JNX Sports markets The Curse! as vegan and gluten-free on current brand pages (no animal gelatine in the powder formula). Always check the tub you buy for the allergen and diet statements for that batch, including any “may contain” shared-equipment notes.

Does The Curse contain beta alanine?

Yes. Matched Curse panels put beta-alanine inside the 3,000 mg Energizing Muscle Fuel Blend with creatine monohydrate and citric acid. Shadow and Ripper also list beta-alanine. Tingling skin (paraesthesia) is a common, usually temporary effect.

Is The Curse Stim-Free Pump caffeine free?

Yes. The Curse! Stim-Free Pump is labelled caffeine-free / stimulant-free. Matched one-scoop facts centre on citrulline malate, betaine, beta-alanine, arginine, taurine and tyrosine with electrolytes — use it for evening sessions or when you want pump ingredients without caffeine.

Is JNX creatine monohydrate?

The Curse! Creatine powders on GymStack are micronized creatine monohydrate (unflavoured 300 g and flavoured 350 g options), with creatine chews also listed. Brand powder servings are typically 5 g creatine monohydrate per scoop. Creatine increases physical performance in successive bursts of short-term, high-intensity exercise at 3 g/day.

Can I stack The Curse with other pre workouts?

Do not stack The Curse!, The Shadow! or The Ripper! with each other or with another high-stim pre-workout or energy drink — caffeine adds up fast. Brand guidance allows pairing Curse with non-stim products such as The Curse! Creatine or Stim-Free Pump; still follow each label and the 18+/pregnancy warnings on the stim lines.

Was The Curse made by Cobra Labs?

Yes historically. The Curse! launched under Cobra Labs; the same brand family now trades as JNX Sports (Just Nip It). Older “Cobra Labs The Curse” searches and tubs refer to the same product line you see as JNX Sports The Curse! today.

The Curse vs C4 — how much caffeine?

On a one-scoop basis, matched Curse panels list 155 mg caffeine. Widely sold Cellucor C4 Original panels are typically around 150 mg caffeine per serving — a similar moderate band, not a Shadow-level dose. Formulas otherwise differ (Curse uses a creatine/beta-alanine blend plus citrulline/arginine; C4 lines vary by version). Compare live C4 options on our Cellucor hub if you want that brand.
