I tried the Whey protein powder form the big box stores...........it doesn’t taste very good. I bought one jug of it and had two wind up mixing just a half portion with a half portion of Isagenix. 2 of my shakes per day include bananas and have since June 2017 and I lost weight. Yes they have lots of sugar but there’s nothing like it mixing with with pineapple or blueberries.
