Myprotein Alpha Pre-Workout Powder with Beta Alanine and Caffeine - Blue Raspberry - 600g vs Beetroot Complex & L-Citrulline 10,000mg

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

Pros

• ✓Improved energy levels reported by most reviewers within 1–4 weeks
• ✓Noticeable circulation and blood pressure benefits noted by multiple users
• ✓Easy to swallow capsules with no aftertaste or digestive upset

• ✗No independent third-party testing (e.g. Informed Sport) disclosed
• ✗Vegan label on listing conflicts with product spec (marked False) — formulation transparency could be clearer
• ✗Effects on athletic performance specifically are modest; primarily a cardiovascular/circulation support product
