no. just get a regular. personally, is one of my favorite protein powders, as this is a 100% whey isolate, and virtually no fat or carbs. the new version mixes great and tastes great as well, give this a shot.
btw, the claim that it increases NO production is just stupid, as the arginine that is present is mixed along with all of the other EAA's, thus conflicting with absorption, and interfering with NO production.
