JNX Sports The Curse!
by JNX Sports
The Curse! is a budget-friendly, high-energy pre-workout with a cult following thanks to its aggressive branding and surprisingly effective formula. At 155mg caffeine per scoop, it provides moderate stimulation, though many users take 1.5-2 scoops for stronger effect. The small serving size and low price make it one of the most cost-effective pre-workouts on the market.
AI Review Summary
The Curse! is a budget pre-workout that excels at providing basic caffeine energy at a very low price. The 50-serving tub at around 15 GBP works out to just 30p per serving, which is exceptional value. However, the proprietary blend and tiny 5g serving size mean active ingredient doses are almost certainly sub-clinical. Best viewed as a flavoured caffeine supplement rather than a comprehensive pre-workout.
