PRE Probiotic Enhancer Peach Mango

This tastes so much like a peach that it no longer tastes real. Does that even make sense? At first you think "Wow this actually tastes like fruit." Then the flavor stays around a little too long, and it starts to taste fake and chemical. Now that shouldn't happen because this is made with organic fruit juice concentrate. I don't know what is causing that to happen. I would blame the probiotics, but the other flavors I've had didn't have that taste. After another sip I put my finger on it. It tastes vaguely diet. I'm going to try to finish the rest of the bottle, but it's really not my thing at all.
