If you look at your amino acid powder, you will see a ratio that will look something like 2:1:1, 4:1:1, 8:1:1 and so on. These ratios mean the amount of amino acids within the powder. For workouts, leucine is considered the best for muscle growth so you the ratio might mean two parts leucine for every one part isoleucine and one part valine. This will typically be described on your BCAA supplement container.\r
