Waste of money...perhaps due to the MAG-10 cost.
And the "whole point of MAG-10" doesn't mean that is the only way to use it. There are PLENTY of experiences outside of scientific studies etc or what is touted on this site that indicate combining a very fast protein with a slow one yields great results. So I don't buy this single-minded thinking towards how to use this type of protein.
MD already has whey isolate in it which is a fast protein, but not as fast as casein hydrolysate. Adding in MAG-10 gives one a fast, medium, and slow protein.
This goes against the popular protein pulsing concepts currently written on this site, but from experience I'm not going to throw away the tried and true slow + fast protein concepts just because of that.
