never heard of it...
sorry.

I've never heard of it either. I might Google "amonia water for sports" and see what happens. You never know.....

here's one link I found, there's many. apparently you can get it at Walgreens, $3.00 for 2 bottles.

Major League Baseball teams use ammonia towels. I don't know how it works. As far as I know you don't drink it but rather soak a towel with it. Usually the team trainer towels down the starting pitcher when he comes to the bench. Most MLB teams use a colored towel as the "Ammonia towel" so as not to confuse it with a dry towel, which is usually white.
