any lifters here take Amino Acid supplements?

[purbeast0]

I know that amino acid's are pretty essential to building muscle mass, and I would like to know which brand of these people have used and had good experience with. I am about to order some stuff online and wanted to find out a good brand beforehand.

I have heard the capsules are huge though and are kind of hard to swallow, and I am not sure about the liquid or powder kinds. so what kind would you recommend ?
