I waited for almost two months to try this product. At the time only the chocolate and vanilla were available, so a purchased two 5 lb vanilla tubs. I was so excited to try it until I tasted it. It is disgusting. I'm not sure if I should send it back and try a different flavor or just spend my money on another brand. I'm disappointed so far. :-( .

This was a good product at a good price point when it was $29.99. Unfortunately now it is just another overpriced whey protein blend. Bummer MGN. I think for a protein blend I will stick to my 6lb bag of Muscle Milk from Costco for roughly the same price.

I got a lot of the flavors. Good Product, just wish the fat wasn't so high. My main complaint is that they do not list the BCAA's on the container!!! I knew I wouldn't have bought a protien without it, but when I looked at the container it doesn't list it on the front or even under the breakdown of ingredients. It has a couple of words in the descriptions and that is it. You have to come to the website to see them listed. I almost bought more BCAA's because of it!!! Please get them listed on the container!!!

Flavor: Cake Batter

This stuff is disgusting in so many ways, and I question the quality of the ingredients. I mixed this stuff in a small blender so that everything was perfectly mixed. The amount and consistency of the foam produced is like nothing I have ever seen. The foam was almost like foam hand soap in its thickness and consistency! Leave this stuff sitting ofr more than 30 minutes and the resulting foamy sludge is unbearable. Although the flavor system itself wasn't terrible, this shake tasted like it had TONS of sucralose in it. These days, when whey is increasingly expensive, I like to save as much $ as possible. However, it's not worth it with this stuff. Spend a few extra and get something from a more well-established company...

Guys, this product is loaded with non dairy creamer..... and honestly, don't really think the amino acid profile is accurate. Taste was like a bad cup of gas station coffee with carnation instant creamer filling in the gaps of this over rated product.

I didn't find this flavor to be as "lights out" as others did. It tastes like regular chocolate to me and I personally MUCH prefer the Cake Batter (sold out as of now) flavor!
