I use Trueprotein.com BCAA. I use a blend of 80% instantized BCAA / 10% Leucine / 10% glutamine peptide and i get the Raspberry Lemonade BSL flavoring. That blend runs me about $55 for two pounds, that also includes shipping. The shipping is a little slow, but the product is good. Some day's I use up to 100g of this mix. Very good stuff.
