It’s important to understand that our EAA Complex includes all of the BCAA’s (Branched Chain Amino Acids) that you have used in the past, including a precise ratio of leucine. Research shows that blood levels of these KEY amino acids are directly related to muscle protein synthesis, so we formulated a comprehensive and efficient matrix to enhance lean mass directly and indirectly, and under various conditions. Now, that ratio is important, but there are some other very exciting points about this formula. Unlike some of the amino acid supplements on the market, you aren’t paying for cheap “filler” ingredients such as dextrose or maltodextrin when you purchase Purple Wraath. Also, we chose not to include the amino acid glutamine since it is not an essential amino acid, and our bodies can synthesize it on its own in sufficient quantities. Because the studies that we based this formula off of do not use tryptophan and since it has the potential for “sedative” like side affects, we designed Purple Wraath to be completely tryptophan-free.
