Best protein flavors!!! Tastes so good!!

I've gone through many different flavors as I try out the full spectrum of options available. So far the Cafe Mocha flavor is my favorite one, it reminds me of the smell of coffee in the morning. Flavor is great and just got a 5lb tub of it. Also purchased the chocolate peanut butter and the clear whey in the flavor cherry limeade. Other flavors purchased include chocolate fudge and vanilla butter cake which I'm also a huge fan of them. I think my favorite part of ordering from this company is how good everything tastes, everything always mixes well (I use water), and the shipping time is quick as well. In the last 2 orders I made they included extra protein crisp bars for free. I won't buy from anyone else again this IS the company for me.
