This is a review for the Iso-100 Clear Ready to drink! macros for this RTD are great! 40 grams of whey isolate - NO FAT - & only 2 grams of carbs. This is perfect for anyone. Hardcore workout junkies, competitors or just any person who is looking for great protein in a not so thick - milky shake!. The taste is very light and very refreshing which is my favorite part. SO many ready to drinks are heavy, milky and even chalky. This ready to drink tastes like juice without the sugar & carbs. I loved the fruit punch (which is odd for me because I usually despise that flavor.) I cannot wait to try the grape!
