Myprotein Alpha Pre-Workout Powd...

Pros

  • Strong, fast-onset energy and focus driven by 300mg caffeine paired with 250mg L-theanine for smoother delivery
  • Effective pump from an 8g citrulline malate dose, which is at the upper end of evidence-backed ranges
  • Good value for money — consistently praised as one of the more affordable high-stimulant pre-workouts
  • Pleasant, drinkable flavours across multiple options (Blue Raspberry, Strawberry Laces, Orange Mango, Orange)

Cons

  • Reported quality control issues in recent batches — powder turning green and hardening into solid lumps within weeks
  • 300mg caffeine per serving is very high and unsuitable for caffeine-sensitive users or evening training
  • Not third-party tested, so label accuracy and contamination risk cannot be independently verified
  • Beta-alanine paresthesia (skin tingling) is strong and may be off-putting for beginners or those unused to it

Best For

Experienced gym-goers with established caffeine tolerance High-intensity or strength training athletes Morning or early afternoon trainers only Budget-conscious users seeking a potent pre-workout
