Sounds fcking awful, lol!
I've never tried any of their casein other than vanilla and chocolate. Used to love the vanilla, can't stomach it anymore. The chocolate is decent IMO, but I haven't had it straight (i.e. not mixed with the Pro Complex for which I happen to prefer vanilla, which completely changes the flavor profile anyway) in a long time. They have a cookies and cream one that's decent. Don't bother with the PB chocolate though, yuck!
