no its not, what makes it better?
its may be better than some of the varieties and brands but not all of them, peanut butter is a simple product and the differences between them are minimal at best.
i buy the natural organic stuff from asda and its like 100% peanuts or thereabouts, myprotein's stuff is like double/triple the price in comparison
