The premixed (liquid) clear Isopure is good, most of the flavors are fine. I particularly like the Alpine Punch and the Apple Melon. But the powdered variety, while cheaper per gram of protein, is simply disgusting. It does not dissolve well, is chalky, and has a nasty aftertaste. Spend the extra money and get the bottles. Plus, you can sample different flavors easily this way. If you get the powder, you get a huge, expensive tub of one gross flavor.
