How "flavorless" is the unflavored protein powder?

I took like the Unjury brands.  I lived off the Chicken Soup the week after surgery.  The plain has a bit of a smell but seems to work.  The flavored ones are not very flavored in my opinion but they work.

Thank you all for your input!  I especially loved the colorful descriptions (tastes like pee and popsicle sticks)!  Made me laugh out loud and got the point across lound and clear.
