Bests & Worsts Reviews from Amazon

I have a chocolate protien shake with peanut butter, oatmeal, milk and ice all of the time and love it. Added creatine and couldn’t even finish it. At first few sips it was a subtle chalky off taste but after a few more seconds tasted unbearable, very chemically. Hard to describe. Gave to my spouse and almost spit it out. This thing has amazing reviews and most say it has 0 tastes and only a few say it’s aweful. So do you think I got a bad batch? Or maybe some people like me react to the taste differently but odd my spouse would say the same. Not sure if I should try another brand or return and reorder this? It was sealed and looks normal comparing to photos. First time having creatine.
