It's not absolutely unbearable But if you've gotten used to the original taste of the red carton muscle milk you'll definitely notice a huge difference... it's just got a strong (gross to me) aftertaste that just sits in your mouth after the first sip and doesn't go away till you rinse your mouth out. I was however able to get a refund so that's nice! I think I'll be trying the premiere protein shakes next!

The original flavor/formula was my kid's safe food for breakfast for like the last 4 years. He refused this after one sip. I thought he was overreacting. Then I tried one this morning. I am super adaptable about my protein shakes and have never had one before this that I would actually call disgusting, but this one is, and now I have to suffer through 16 more of these so I don't waste the money we spent on them while still finding an alternative source of protein my kid won't refuse while he's in the middle of a growth spurt. This is about $600/year we would spend on these that Sam's won't have any more, and since this was my main motivation for the membership, we may not renew next year if the original aren't available again.

The flavor is TERRIBLE! I tried one and thought ... not good but tried the second one and I can't stand the flavor. I wish there was a return policy for the rest cause I'm not going to drink them. I will be throwing them out! The previous Muscle Milk with 25 grams of protein was good and I have purchased many in the past but this 33g is AWFUL!

I see a lot of complaints about the flavor but honestly it's super mild. It's mildly sweet and mildly chocolately without any strong chemical or bitter tastes. I'm personally a much bigger fan of this Muscle Milk than the old version. In fact I've had lots of protein shakes worse than this. It's easy to drink, it has 33 grams of protein, and doesn't include sucralose, acesulfame potassium, or aspartame all of which mess with my gut. 9/10 protein shakes and bars include one of those 3 so when a product comes out that I can safely consume, it's awesome. These use stevia which is great, and from what I can tell, not a lot of it. It has 11 grams of carbs including 3g of naturally occurring sugar and 2g of fiber. It's ultra filtered milk, there are going to be carbs in it. 9g of net carbs is basically nothing. Even though I'm on a severe carb restriction, those macros are perfectly fine for me especially considering its insane nutrient density and low cost per gram of protein. Typical protein foods will cost around 10¢ per G of protein whereas these work out to 5¢ per gram of my math is correct. This will be one of the only 3 protein shakes I go for now, so I'm glad Sam's has started carrying it so I can get it for a good price. Anyway, I felt the need to offset all the complaints happening because at the end of the day, it's a protein shake. It's a utility. The fact that it tastes even halfway decent is a blessing. If I want something super delicious, decadent, and indulgent, I'll go buy a milkshake and take the calorie and nutritional hit. Not everything has to be the most palatable thing in existence. Review not sponsored. I just don't want Sam's to stop carrying it.

SO DISAPPOINTMENT WITH THE “IMPROVED” FORMULA! It tastes like a weak, watered-down chocolate drink, not at all like a shake. I WILL be changing to another brand after being a regular consumer of Muscle Milk Chocolate Shake formula for over 8 years! I drank one every day, sometimes two. I'll drink the rest of the pack I purchased like I would drink medicine, but will not be purchasing more! Gave the product 2 stars only because it's still nutritious, even though it's no longer sugar-free.

I am so glad there is finally a better option from Sam's. I avoid all the artificial sweeteners like Sucralose and Ace K, and although Muscle Milk was my first protein shake brand ages ago, I stopped drinking it all this time because they always had such terrible ingredients. I am very pleased to see this new formula, it is hands down the cleanest protein shake I have seen. Even most other clean ones still use seed oils, this doesn't even have that! It's not a perfect chocolatey taste, but I will say it is so so close. There is just a tad bit of something missing, maybe a tiny bit more cocoa, then it would be perfect, but this is till a really good shake in my opinion. I am very pleased to welcome Muscle Milk back into my routine, it is definitely a nostalgic brand for me!

Horrible taste. This is like leftover milk from chocolate cereal. Weak muted taste in comparison to the 25 g that Sam's discontinued. We were avid buyers of this and my wife and I would drink two a day, now it looks like we have to choose something else.

[This review was collected as part of a promotion.] This stuff is amazing! Muscle milk never fails and always produces great protein drinks. It's easy to digest, the ingredients are clean, doesn't have a horrible after taste, value is superb and the serving size is just right. Can't wait purchase another case!

[This review was collected as part of a promotion.] These protein shakes are creamy and smooth. They have a light chocolate flavor that’s pretty subtle. They need to be served cold for the best taste, so I usually add a cube of ice or two to mine. Overall, these are an excellent way to consume a lot of protein in a quick and easy way. I really like the convenience of them and the ability to grab and go.

[This review was collected as part of a promotion.] I’ve been wanting to try these so I was super excited to get this campaign! I love that they have 33g of protein and only 3g of sugar. It’s hard to find shakes with low sugars. It’s super convenient when you’re on the go. I’m not a huge fan of the taste, I think it could be a little better but it’s doable.
