Great drink Great value
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
Love these drinks 30 grams of protein can’t go wrong. They taste is good the texture is not an issue. I blend mine with ice you can even put coffee in it and that is amazing.
It is like a choc cappuccino.
I feel better when I drink one in the morning.

A small drink of chocolate packs a large amount of protein
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
These drinks are very convenient. I can take them with me if I’m running behind or I can just drink them here at home. The taste isn’t bad, I can handle it, but it’s not like drinking a glass of chocolate milk. The texture is quite smooth as it is already mixed up for you and it is always the same. I have never had a batch that is not been the same taste. I like that I can drink a small bit of chocolate and gain 30 g of protein.

Drink one every day over ice! Great taste!
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
I’ve been getting Premier Protein Shake on auto delivery for a while now, and it’s one of the best decisions I’ve made for convenience and consistency. Each shake packs 30g of protein with only 1g of sugar, which makes it perfect for busy mornings or a quick post-workout boost without the guilt. 
The auto delivery is a game changer—no more running out or last-minute store trips. It just shows up right when I need it, and I can easily adjust or skip deliveries if needed. 📦
Taste-wise, the shakes are smooth and actually enjoyable (not chalky like some others). I’ve tried a few flavors and haven’t been disappointed yet.
If you’re looking for a reliable, grab-and-go protein option with zero hassle, this subscription is 100% worth it! 💪

Low Calorie, Great Taste!
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
I started drinking Premier shakes while recovering from lapband surgery in 2012. They are delicious, low calorie , high protein meal replacements, with no added sugar. I have tried most of the flavors and I have 3 -4 favorites that I rotate. They are great on the go and a good addition to iced coffee. A good part of my weight management process.

Great quality
We had a banana tree in FL and these are every bit as good tasting. They are perfect, not over ripe and not hard.
Totally as good as the ones we picked in FL. The price we paid to the ones at the story locally. We think the value for the product is super.
