They changed the Premier protein shake formula & I don't like it

I wrote to premier a few weeks ago complaining of the same thing. They said they didnt change the formula at all and would forward my information to quality control.
They wanted run dates and production numbers.
Within a week or so, they sent two new cases and they were fine.
I havent needed to buy any more yet......but I will. Just kind of waiting for the yucky supply at Costco to be purchased.
I would write them for sure...they need to know!!!

What I do is add 1/4 cup to 1/2 cup of 2% milk to the new ones. It tastes so much better. Not thick and not super sweet. Just right. And I get an added 5 grams of protein.

I got some like that too, i took it back and got new stuff, and pleased to tell you that it was not thick at all and tasted the same as it always has..

good thing with costco is they replace it even if you have drunk some and no questions asked...

I actually called the company today - before I read any of these comments - I wondered if the new container could have affected the taste - it has a yucky after-taste now - I have been using it 3 times a day since October and noticed a change in taste at the time the package changed.  Wondering if something in the packaging is making the taste different.  Customer service said only the  outside of the packaging changed, not the inside.  But it really tastes different to me - glad others have noticed as well.  I also bought mine at Costco...
