I really like a lot of the Xtend line of Amino Acids, Pineapple is good (VERY tart though), blueberry / blueberry lemonade both being my favorite so far. The Watermelon Lime flavor tastes a little watered down, even when I double up on scoops in a 16 oz. bottle I don't really have a lot of good flavor. Makes me think of licking the rind of a lime, that or running water of the back of a lime into a bottle of water and then drinking that. Again, their other flavors are pretty solid, I bought this one specifically for the l-carnitine for some assisted weight loss, so instead I recommend just purchasing another supplement with that amino in it and mixing that in with one of their other flavors.
