Glutamine Peptides instead of L-Glutamine in PW Drink?

Has anyone tried using glutamine peptides instead of L-glutamine in their PW drink formula? Doing a little research it seems that the peptide version would be absorbed more quickly and therefore a better choice.

Peptides are about the only useful form of L-glutamine supplement. About 90% (or more) of straight L-Glutamine gets digested for fart gas - Peptides, however, are mostly biologically available to “do their job”. I’m always amazed at how popular straight glutamine is when is way less efficient (and efficient is what matters) and pretty much a waste of money. Go with peptides any day. I dare anyone to prove to me that straight L-Glutamine does shit other than give you a nice placebo effect!
