I usually buy the 10lb or 5lb Optimum bags but I see this stuff from Schwartz is reasonably priced and I like to contribute back to the board and it's affiliates where I can (big up to Finakits.com, the best in the biz!!!!!). Anyone ever tried this protein? Do 2 scoops mix up in a shaker with 12 oz of milk or does it clump up? Is it clean protein or does it make you bloated,etc.? Let me know. Thanks.
