Good protein, trash price.......

It took years to get a decent protein back after they stopped selling muscletech. This was a reasonable offering. Too bad they just increased the price by almost 25%. Sams makes it hard to justify my membership....

Protein

The protein is a decent size that is able to last you for an extensive period but dang! In the last 2 weeks, the price has increased only 10 bucks while everything remaining the same. Smh

Samsclub raised the price....AGAIN

After 15 years of shopping at Samsclub, I'm canceling my membership. I'm sick of the constant price increases. Its no longer worth the membership since everything is either same price or cheaper elsewhere.

Worth the price.

This is really good protein powder. But I am astounded by how much the price has increased recently! But I will continue to buy because it is so good. Unless it becomes unaffordable.

The 'Milk Chocolate' Flavor is Disgusting

Optimum Nutrition is absolutely the BEST brand of whey protein isolate, HOWEVER, I will never purchase this flavor again!! The Extreme Milk Chocolate flavor is absolutely disgusting. It stinks as if spoiled and taste the same way it smells. ON's most popular chocolate flavor is their 'Double Rich Chocolate' which is the one I would expect Samclub to carry, as the most popular flavors would best serve members. The Double Rich Chocolate flavor, when combined with milk, yields something that tastes like a supermarket chocolate milk which is universally enjoyed. The powder fully dissolves and has no aftertaste unlike the 'milk' chocolate flavor. Please discontinue the milk chocolate flavor and replace with DOUBLE RICH CHOCOLATE, and I will be a frequent buyer. Till then, I will have to purchase our whey protein powder elsewhere.

Thanks for choosing ON! Extreme Milk Chocolate is a Sam's Club exclusive flavor but you may check out our shop page to purchase Double Rich Chocolate!

Bad taste

This contains artificial sugar and a type of corn syrup. Both are unhealthy and also have a bad taste. I gave it 2 stars for not containing the higher amounts of lead that other powders contain. I wish I purchased a smaller version to taste before buying this.

Love this product

I absolutely love this protein. The taste is on point, it’s easy to mix and has all the necessary amino acids. Also mixes very well

Highly Recommend!

Very good/smooth flavor! Reminds me of Nesquik. I honestly couldn't believe how good it was with just water, then I put it in some milk and omg it's good.
