Protein that'll change your life

Been buying a few 10lb bags of this protein for years! Love the flavor and size! Makes ordering once a year easy!

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.

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....

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.

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

Tasted good not worth the price.

Tasted good and I liked it but the price now is out of control. I bought it at 49.99 and now it’s over 70$ nope. Took it right out of my cart.

Thin/watery with a sour taste

It is thin/watery with a sour taste. Not sure why there are good reviews. I now have over 5lbs to use up...

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.
