Got mine yesterday. Anyhow....
Tastes like Fruit Punch but it is blue colored.
To me it seems like it has a blue raspberry hint in it. Moleculars Whey Fruity Fruit Punch tastes more like fruit punch but I do not like the aftertaste of theirs. I like the taste of Crystal Sky a lot more and it does not have a bad aftertaste.
Mixes great...right up their w lemonade & fuzzy navel...Mixes better than Apple, Cherry, Kiwi-Strawberry. No clumps or unmixed powder problems.
Only thing I do not like is after I drank it my lips turned blue

(wiping your face takes care of the problem)
I still prefer the taste of Fuzzy Navel (my fav) and Lemonade but this is a good flavor and IMO way better than apple.
I'd give it 4/5 where id give Fuzzy Navel 5/5 and lemonade 4.5/5.
But if you like fruit punch I would definately give this a try. I am not the fondest of fruit punch anything.
