ProLab Beta Alanine Powder is 100% pure, flavorless beta alanine with no fillers or additives. Beta alanine floods the muscles with the specialized amino acid carnosine to work as a buffer against lactic acid buildup. It is this lactic acid buildup with causes the burn and muscle fatigue often felt during high intensity exercise. Buffering the muscle acidity can help allow you to train at a higher intensity for a longer period of time before fatigue sets in and may yield a few more growth-stimulating reps. ProLab Beta Alanine Powder also supports prolonged stamina and can help reduce muscle soreness both during and after training allowing for faster recovery time between sets and between workouts. You do your part. We'll do ours.
