I personally am all over the green apple. I'm killing 2-3 servings a day right now and loving it. I actually like a bit more water than is suggested to make it not as sweet. With extra water it's SUPER refreshing!
No other BCAA product out there will compare to RPG in regards to taste. The apple was my least favorite...it was refreshing and very good but it pales in comparison to the warrior melon and especially bubba punch
