A high-quality pre-workout can mean the difference between a mediocre gym session and hitting new Personal Records (PRs). However, many commercial pre-workouts rely on massive doses of cheap caffeine while skimping on proven vasodilation and endurance ingredients.
5 Essential Ingredients Every Pre-Workout Must Have
| Key Ingredient | Clinical Effective Dose | Primary Benefit |
|---|---|---|
| L-Citrulline (Pure) | 6,000 mg – 8,000 mg | Drives Nitric Oxide production for intense muscle pumps and blood flow |
| Beta-Alanine | 3,200 mg – 6,400 mg | Buffers lactic acid buildup to increase endurance during high-rep sets |
| Betaine Anhydrous | 2,500 mg | Enhances power output, muscle cell hydration, and explosive strength |
| Alpha-GPC or L-Tyrosine | 300mg GPC / 1,500mg Tyrosine | Crosses blood-brain barrier for smooth mental clarity & tunnel focus |
| Caffeine Anhydrous / Malate | 150 mg – 300 mg | Boosts central nervous system arousal and metabolic output |
