This is great for getting the actual recommended dose used in studies (3.2 - 6.4 grams). Pretty much every pre-workout only has half the minimum dose that you need, because if you take too much at once you get a tingling feeling. Thats why I take this once or twice a day at different times than my pre-workout, and its given me great results. I prefer this Beta-Alanine because its the high quality CarnoSyn brand that the original research was done on, and it has a great price in its pure powder form.*
