Avoid Holland & Barrett's Banana flavored whey protein. The taste is ok upfront but a funky after taste leaves you wishing you made a different choice.
I recommend Natrual, it mixes much better with food (soups, yogurt, etc. NOT cottage cheese).
Unfortunately, I went for the value 2.5kg tub of Banana which will probably last long enough for me to get used to and possibly addicted to the funk.
