What's small and powerful and full of protein?
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
This is better than expected - filling - chocolate-milkish taste - lots of protein - only o few calories - good for
times you want to eat less but still have energy - It is a good product to have on hand - it is filling - this
is not exciting but rather useful in a busy life -when you don't want to cook, before a medical procedure
or any situation where less is more. The taste is good enough - best ice cold - I would recommend this
product.

Good taste, No sugar, Low Carb, High Protein
Flavor Name: Chocolate, Size: 11 Fl Oz (Pack of 12)
Highly recommended, no sugar, low carb, high protein.
This exceeded my expectations. It tastes good chilled, much better than other forms of protein supplements.
I have never had a ready mixed protein shake, so I was hesitant about buying it.
Protein powder always tasted too strong & not good after taste.
Although there are some Ok Protein bars, they do mostly have undesirable taste & not good after taste.

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! 💪
