Decent Chocolate Peanut butter flavour, and texture. I really enjoyed the chocolate biscuity bits on the outside of the bar.
I think I prefer the Arnold Muscle Bar over this, but only slightly, because of the slight aftertaste that this had.
But that said, I could quite happy destroy a number of these bars in one sitting.
Formula wise its pretty good at 210 calories, reasonably low fat for something that tastes so good.
Kinda expensive at over $4 per bar, but if you want a great protein bar this should be at the top of your list.
