for a while i've just being doing the same as most people with BCAA powder, mix it with water and neck it!
then i tryed Scivation Xtend and it was just so much better then putting up with the nasty taste of BCAA's but it cost twice as much as buying standard BCAA powder, some people say thats because it has glutamine in it aswell but glutamine is one of the cheapest products out there. i buy 1kg for €20.
what ive started doing now is something i really like, just using concentrated lime juice. it really takes the bitterness out of BCAA's and i would say its even border-line pleasant to drink :P
all i do is: 150ml concentrated lime juice (u'll need about twice as much if its normal lime juice)
make it up to 500ml with water
10g BCAA's
5g L-Glutamine
works amazingly well and i think people will like it alot more then forking out excessive money for BCAA products or having to bare the taste of drinking it with water.
