Do not buy - it refuses to blend - 01/19/2015 Overall Rating:1 out of 5 Reviewer:Smitty from Cleveland, oh Product:ISS Research Whey Matrix
Horrible product it has two jobs, to blend and fortify your body. I can tell you it will sit under your sink because you will despise having to mix this crap!

This protein mixes bad! There's tons of clumps in it every time. On top of that doesn't even taste that good! What the heck are these people thinking. Time to go back to the drawing board.
Absolute Worst Mixing Protein on Planet - 06/13/2012 Overall Rating:0 out of 5 Reviewer:Shedward Reviewer from Boston, MA Product:ISS Research Whey Matrix
ABSOLUTE WORST MIXING Whey Protein in the universe. It clumps up seconds after mixing for 3.5 minutes. I would not take a lifetime supply of this crap for FREE.
I gave it a try, won't be re-ordering - 07/13/2010 Overall Rating:2 out of 5 Reviewer:Dave from Orlando, FL Product:ISS Research Whey Matrix
This Whey Matrix seemed pretty good by the description and the price was attractive as well. Unfortunately, I find it does not mix with a spoon at all, despite the description. I also had trouble digesting this product. The vanilla flavor is nothing to write home about either to top it off! I'm going back to CytoSport Complete Whey.

This stuff is unacceptable. The only way you can mix it is in a blender. It does not taste nearly as good as other brands, Cytosport, Six-Star, certainly not Nector. In a weak moment I bought 5lbs at my gym, I am about to toss it..or though in some water to patch my driveway.
