Well after posting about the low carb ketchup I figured some people may be interested in this as well. A few weeks ago I bought a 25 lb bag of True Protein Whey Isolate which is on sale for an awesome price right now: http://www.trueprotein.com/Product_Details.aspx?cid=22&pid=6842 It comes unflavored but they have flavor packets you can add yourself. The protein itself mixes pretty easily(at least as easy as any whey can be) and has a very neutral flavor that takes on anything else that you want to add to it(extracts, fruit, etc). I was using it unflavored for the past two weeks but I just received in the mail 3 different flavors to add. I ordered the premium flavor packets in Dutch chocolate, Vanilla cream, and mocha. I have tried the mocha and chocolate so far and they are amazing!!! I am really impressed with the quality and they contain no sugar as well. They offer a ton of flavors so ill def be ordering some different ones. http://www.trueprotein.com/Product_Details.aspx?cid=57&pid=6777 Also I had to call once regarding the order and their customer service is stellar. I would definitely recommend shopping with them. They offer a ton of different custom mixes as well with many different types of protein(great for if you have any allergies).
