Is JNX Sports The Curse! worth buying?

“The Curse! offers genuinely cheap caffeine energy—155mg per scoop with 50 servings per tub and a widely praised Blue Raspberry flavour—delivering reliable energy and focus within 15–20 minutes. The 54/100 score reflects the main limitation: it's essentially a caffeine-only product due to the proprietary blend, leaving you without transparency on what else you're consuming.”

— AIScored Editorial Team, Mar 2026

What Do Reviewers Say About JNX Sports The Curse!?

Sample excerpts from currently available source material used in this product analysis.

"The Curse lives up to its name - extremely potent pre-workout. Amazing energy and focus but the crash is devastating. Also overpriced for 50 servings, tastes like sour candy, and keeps me awake for 8+ hours. Use sparingly due to harsh side..."

Reddit • CursedLifter

"Had to stop using after developing tolerance too quickly. The tingles are unbearable, taste is artificial, and withdrawal symptoms were bad. Expensive habit that became unsustainable. Prefer natural energy sources now after this experience."

Reddit • CaffeineCrashed

"Tasty snd convenient. Easy to take and pleasant tasting. Not sure yet as to the benefits as im only taking them a week. I'll buy them again."

"Delicious. These taste really lovely. I haven't been taking them long enough to know if they'll make any difference but I look forward to having them every day."

"Collagen sachets. I love the individual sachets as you can take them with you when you’re on the go"

Pros

  • +Delivers reliable caffeine-driven energy and mental focus within 15–20 minutes
  • +Excellent cost-per-serving ratio — one of the most affordable pre-workouts available
  • +50 servings per tub with good flavour options (Blue Raspberry widely praised)
  • +Suitable for vegans and free from gluten, dairy, and soy
  • +Moderate 155mg caffeine dose is manageable for most adults without extreme jitters

Cons

  • -Full proprietary blend hides all doses except caffeine — impossible to verify clinical amounts of beta-alanine, creatine, or citrulline
  • -5g total serving size strongly suggests sub-clinical doses of key actives (beta-alanine needs ~3.2g, creatine needs 3–5g alone)
  • -No third-party testing (no NSF, Informed Sport, or Labdoor certification)
  • -Contains artificial FD&C food dyes; L-Arginine AKG is an outdated pump ingredient outperformed by citrulline malate

Best For

Beginners wanting a low-cost entry into pre-workouts Caffeine-sensitive users preferring a moderate stimulant dose Budget-conscious gym-goers who prioritise energy over ingredient transparency Users who tolerate beta-alanine paresthesia without concern

Watch Out

  • !Proprietary blend makes it impossible to confirm effective doses of any ingredient beyond caffeine
  • !Rapid stimulant tolerance reported by regular users — cycling is advisable
  • !Higher doses (1.5–2 scoops) increase crash risk and may cause anxiety or sleep disruption
  • !Not suitable for those sensitive to stimulants, artificial dyes, or late-evening training
  • !No third-party purity certification — not appropriate for tested athletes
