I am an elderly woman who is suffering from kidney and heart issues. I don't have much appetite, so also losing muscle like crazy. I am looking like all those other wrinkly, skinny old people I said I wouldn't. So my doctor said high protein shakes. Okay.
So I started researching. Because of price and ratings I started with a couple 4-pks of Premier from a local grocery outlet. Cafe latte...Yum! Then I went to Amazon to get regular deliveries because I no longer drive. Read lots of reviews. I noticed some mentions of outlets besides Amazon. I also noticed a link to 'Premier Store'. Given the bad reviews re slime and expiration dates, I carefully made sure I wasn't ordering through an outside source. Don't know if that actually helped, but I have not had any of those issues out of 180+. Although, to make sure on the slime, I open a bottle before shaking and check inside the neck, to wipe it out if suspicious. Then re-cap and shake, shake, shake. (One could also pour through a fine strainer and/or cheesecloth to not waste it.)
Besides Cafe Latte, I have tasted Peaches and Cream, Vanilla, and Strawberries and Cream. None if these are strong flavored, but I can taste the chocolate and coffee in my favorite. The Vanilla is refreshing, as is the Peaches and Cream (which has a delicate peach flavor). The Strawberries and Cream is cooling and not untasty, just not much flavor. And I have added Bananas and Cream, which is also nice but mild.
One more issue: digestive issues.
Some people's innards don't like the soy and some other ingredients. Others are more forgiving. I get some bloat but the benefit I receive outweighs any mild discomfort. Just because some people can't tolerate this product doesn't mean it's bad.
My last note...lead. Lead is bad. But I have been around lead for many decades, from leaded gasoline polluting roadside blackberries (oh, no!) to lead in paint for all kinds of things. It hasn't had much impact on me (that I know of) and I am not giving these to anyone else, so, in the meantime, whatever life I have left will not be spent worrying about it. Granted, you younger people and children do need to be cautious.
Ain't it fun?

UPDATE: 23 Oct 2023
1. To start, the shakes I get are shipped in thick, heavy-duty boxes in which the shakes are closely and firmly packed and the company name and other pertinent info is printed on the outside. If yours isn't you could have issues from an outside vendor, such as expiry dates and improper storage, not to mention higher prices.
2. Regarding the slime and stomach issues, they appear to be caused by the same "problem"--- the protein. While some flavor have two types of condensed (is that the word I want?) milk proteins combined.. Some have soy. The proteins sometimes separate a bit causing the slime. My suggestion above still holds.
And, I'm sorry to say, the stomach issues are also caused by the milk proteins and lactose. Over 60% of Americans suffer from some level of lactose intolerance (not allergy); an individual's level of intolerance will determine how bad you feel.
Jeeze!
Finally, recycling the bottles: Rinse and zip off the cover which is discarded. Done. BUT if you live in either Oregon (me) or Maine you have the option to redeem the bottles for 10 cents if the portion of cover stating that is still attached. Granted it's not a lot, but it builds.
(Oregon is in the middle of the Cascade Subduction Zone ... Inevitable massive earthquake...when, not if. So I am donating my $6 a month to our CERT I program to buy supplies. )
The choice is yours.
Now I'm done! Have a healthy life.

These protein shakes are positively delicious! You can drink them cold or at room temperature and still thoroughly enjoy getting your 30 grams of protein per bottle. I had gastric bypass surgery in February of 2022, and I am required to consume at LEAST 60 grams of protein per day, which means consuming at least two shakes or the equivalent in foods products each day. Since my stomach is but a fraction of what it was pre-surgery, I find it MUCH easier to just drink one of these cookies and cream shakes in the morning and one in the afternoon/evening. I've tried several flavors, but the cookies and cream is my absolute favorite!

We drink many of the Pure Protein shakes, but this is the first time for the root beer float flavor. It is a great flavor that brings back childhood memories of going to the ice-cream truck. Flavor very tasty making you want more. If people don't like protein drinks or are scared to try, this is a good drink for the beginner. A good way to get protein in if needing to push intake and not wanting to eat more solid foods. All three adults in our home need to increase their protein intake and while we like all the flavors of Pure Protein and we each have a different favorite; Root Beer Float is likely to become someone's new favorite. Planning to buy more of these soon the case is over half gone in less than a week.

It's hard to find a good tasting protein shake without a bad after taste, I love root beer floats band decided to give this a try and I was absolutely amazed at the taste, It was so delicious, I drink it after my workouts, and it cuts my appetite and keeps me full, Now it's not gonna taste like a sugared up milkshake but it's delicious. Premier protein shakes are the first I have ever enjoyed and I will be buying more flavors, but until then I'm stocking up on my root beer floats.

This is the Premier Protein Shake, Café Latte flavor. I've bought it repeatedly, and I always buy the 12-packs.

Major plus points for me:
* 30g Protein. One of the highest protein amounts you can get in a prepared shake for a decent enough price.
* Only 1 gram of total sugar and 0 added sugars while also low-fat with only 3 grams fat, 1 gram of that being saturated. Often when something is advertised as low carb/sugar, it will have extra fat and low-fat usually means more added sugars because companies do this to improve/balance taste. This product is low on both and thus, makes a great meal replacement if you'd like to lose weight or stay lean while also tasting fantastic.
* Each container is 11 oz/325 ml, which is also the recommended serving size, and this protein shake provides a great protein to weight ratio at only 160 calories per serving.
* Again, great taste, both chilled and at room temperature -- hear me out 😅. I suffer from chronic pain in my joints and it takes a while for my pain killers to kick in -- but I want my coffee/caffeine sooner than that. My fridge is downstairs and stairs are hard on me, first thing in the morning. Most of these protein shakes do not taste the same when at room temperature. This one DOES! It's as sweet as you'd expect from a Mocha and smooth as any coffee from your local coffee shop (not grainy or mealy at all). So, I don't have to keep it in the fridge and avoid extra pain that would come with retrieving it from downstairs.
* One serving/container has the same caffeine that would be in a cup of coffee -- perfect as I drink it within 30 mins of waking up, rather than just coffee.
* It has 24 vitamins and minerals, which makes me worry a bit less about taking vitamins separately (a quarter of daily recommended amounts) and adds to this protein shake's nutritional value.
* This is a gluten-free product if you can trust the labeling.
* SNAP/EBT-eligible item.

Downsides:
* Allergens: milk, soy
* Potentially problematic ingredients:
The shake has artificial flavoring, high oleic sunflower/soybean oils, phosphates used as preservatives, inulin, and sucralose. So if you want to avoid any of there, you might want to choose a different product.
* Price: All proteins have become so expensive, it's difficult to find a good product that hits all the healthy points without problem ingredients. With this as with similar protein shakes, I sometimes have to skip my purchase or switch to another brand sometimes because I have a fixed budget.

Overall:
One of the better protein products out there. True high protein, low carb AND low-fat. Gluten-free. Great taste and texture/consistency. A lot of benefits. Price could be better but this is also SNAP/EBT-eligible, which is a plus. There are some questionable ingredients but they're also in the majority of high-protein products, in general. The shake does contain the known allergens milk and soy, so IF you're allergic to either, do NOT buy this. Other than that, great product and highly recommended.
