Thanks for your response Eric. I read the article about BCAA on blog. Under BCAA -
"However, other reviewers conclude that most studies show no effects of BCAA supplementation on performance, such as prevention of fatigue during prolonged exercise [13,14] two recent studies support these conclusions. Watson and others  reported no beneficial effects of BCAA supplementation, consumed before and during prolonged cycling to exhaustion at 50 percent VO2max in the heat, on performance time, heart rate, and core or skin temperature. Cheuvront and others  reported similar findings with subjects exercising in the heat, noting no significant effect of BCAA supplementation on time-trial performance, cognitive performance, mood, perceived exertion, or perceived thermal comfort. Although current research does not support an ergogenic effect of BCAA supplementation, most investigators recommend additional research."
and in other article you wrote that you do not suggest to go for amino acid powders.
Isn't it right that BCAA's will get quickly absorbed and will be used directly by the muscles than the process to digest, assimilate the whey and then refilling the amino acid pool to feed amino acids to muscles?
