BCAA's

I have to admit that I've been drinking the Dara Torres Gold Medal Aminos Kool-aid for almost two years. I have experienced weight loss, enhanced muscular mass, and best of all improved swimming. While allowing for the placebo effect, I believe that the aminos have made a difference. Now, they have been discontinued, and I'm trying to find a substitute. (Why they have been discontinued, I have no clue. Bad business decisions? Marginal substances?) I've had a close relationship with the people in the office, and one day, they just didn't answer and I don't know what to make of that. My question is if anyone else has had positive results from BCAA-complex use, and what the alternatives to the "Dara" complex might be. When I read the label, there are a lot of "propriatary" blends, so I don't hope to match it exactly. But surely there might be a close substitute. Anyone????
