I got chocolate and it is one of my favorite proteins. Not lumpy and tastes like chocolate pudding.

Tastes great. Not heavy or thick, like some others. And it's perfect for mixing with other things - the chocolate with my morning coffee is a great start to the day post workout. Highly recommend!

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.

Dissolved quick but as good as some others I have used. Still my go too for universal shakes. Girl friend loves to mix two scoops, one banana, cup blue berries and almond milk as a breakfast shake. Its great.
