I got Isopure and I wasn't liking the taste at first but now I love them. They come in 20oz bottles with 40 grams of protein, they also cost $3.99. I really love the grape. My friend ordered me a box of them from amazon for about $40 for 12 to 16 bottles(i can't remember) but they have them in 7-11 if you wanna try it before you make a big purchase. They have about 15+ flavors. This also counts toward you 64oz Water intake. Hope this helps
