Stick with Proteins that are high in BCAA's and Glutamine. Most formulations will tell you that the protein is "enriched" with both....be careful, you never know what you are getting.
Try Isolean by Scitec....it is loaded with 15g of BCAA's and 14g of Glutamine. It is the only protein/MRP that I have seen that actually tells you the exact amount of amino's per serving.
