Not a fan of the Muscle Milk Pro Series Knockout Chocolate
It's a bit thicker than expected and doesn't blend/dissolve well even in a blender bottle that's been shaken for about a minute. The Knockout Chocolate flavor isn't good and there definitely seems to be something 'off' about the flavor. Not as nearly as good as other protein shakes that I've had, so I cannot recommend.

Terrible option
Terrible protein powder. So thick it doesn’t mix or blend. Take a sip and you’re guaranteed to get a clump of powder. By far the worst protein I’ve tried.

DISGUSTING
Horrible. I almost threw up trying to drink this. It's thick and clumpy no matter how long I shake it and it tastes like stale cardboard with a hint of fart. Don't waste your money!

She thick
It's much thicker cause you use two scoops. The flavor is less sweet. Overall gets the job done if you're not going for taste. You'll have to add more milk/water for this one.

Just kinda gross
Every sip is hard to swallow, like I actually wanted to vomit. Also had to blend it if I didn't want to drink wet chunks of powder Also, it's "50g of protein" because the servings size is massive (this is 82g of powder while other brands can range 25g-40g) so it's not some revolutionary blend

Nope
I feel like it’s 50 grams of protein per serving because the serving is like a cup and a half of the powder. It’s too much and the flavor is not as good as the “regular” formula. I wouldn’t purchase again.

Doesn't mix well, clumpy
The taste is ok, but the consistency is clumpy when mixed with liquid for a shake.

Good 2nd Choice
My husband buys the chocolate when he can’t find the vanilla (which is frequent). He likes it fine and says he sees great results from it.

Highly Reccomend
This thing is just right. Mixes perfectly with milk (you wanna put ab 16 fl oz of milk when mixing 2 scoops of this protein) If you don’t add enough milk it will be too chalky and thick but if you have the right amount of milk it will do you justice!

This is the first one I have ever tried. I bought it solely because of the somewhat cheaper price and 50g of protein seemed like a lot. I noticed tremendous progress while using this. I personally think it taste a lot better in milk than water. Sprinkling it over ice cream is also a good way to add it. It never fully seems to dissolve but it doesn’t taste terrible when you get a unmixed part. I have just kept on buying this since I have no major complaints, so I have not tried anything else. But, I would recommend this.

Goldilocks and The 3 Bears. There. Had to add a title
Really works. Also, never completely mixes. I got rapid gains with this product.

Most protein for the price
I always blend it with whole milk and sometimes add peanut butter using a shaker bottle. It mixes well and tastes amazing. You get a lot more for your money with this protein powder.

Decent Macros
This Muscle Milk Pro Series provides some decent macros per scope (See nutritional label). Some other reviews noted that it doesn't blend that with, especially with almond milk. Can confirm. Did blend well with water though. Would prefer a larger size since a serving is technically 2 scopes and there's only 11 servings. You can go through it pretty quickly.

Not bad
It's ok. Flavor is not bad. It's a bit grainy, does not dissolve easily, but overall. I like it.

Buy something else
This does not blend well with the almond milk that I use. Will stay using the C-4, liked the taste of the better.
