Good stuff!
Mixes easily and tastes great, like a peanut butter chocolate shake. I never get gassy or bloated from this stuff.
I also like the idea of whey and casein, for both fast and slow release protein. BSN knows what they're doing.

Buy this Product!!!
Mixes great just a few shakes with at blender shaker and bottoms up. Tastes protein shake tastes GREAT but this goes down good. 25 grams of protein per serving low cals. can't beat the combo. You have to have protein to build muscle this does the job.
