The source of the amino acids is not the free form of amino acid, instead it comes from caseinates. And similarly if you see the amino acids tablets from the same brand, the source is soy protein isolate which is worse than taking caseinates. So, I consider there is no use in spending money on such a supplement if you can get 2 lbs of whey protein or spend a bit more to get casein and a higher amount of protein. The main motive is recovery and the concept is to get amino acids quickly into the blood stream after workouts. The aim is compromised here due to slower absorption and therefore the protein from the supplement will go through the same process of digestion creating no difference at all for speedy recovery.
