leucine question.

So based on the Layne Norton Study 3 grams of leucine per hour is all we need.

So the question is with this leucine peptide that just came out what would be so great about it if 3 grams maxes us out for MPS. I am going to make a new mix and was thinking of adding the leucine peptides. I can't seem to find any studies on leucine peptides on absorption etc how it is better than regular leucine and such so if any one can let me know that would be awesome.
