The taste is definitely one of the best protein shakes I've ever tasted in my life! It's so good. But, the container could absolutely be filled up more for the price that we paying. Ttmhe size of the container is very miss leading.

Working it out in BootCamp Baby!!!

Great!! I have been using this product for 8 years now

Love it! Have been using since 2018. It’s the only one that doesn’t hurt my stomach or bloat.

This is the best protein i have ever had

Best flavor and doesn’t clump in hot coffee.

One of my favorites!!!

It was very chunky

Which is the best flavor ever?

Doesn’t make me sick the way every other powder does

the taste is good and fulfilling

I this my favorite flavor because it’s not as sweet as the others.

Taste more like coconut

Really love the Carmel flavor because it can be mixed into morning cafe or as an ice coffee!!! Really helps with sugar craving as well!

Taste great! Neapolitan has always been my favorite ice cream flavor. Now I can have it in a healthy protein shake.

The most delicious protein shake ever!

So far soooooo good! Great texture and taste! The only thing i would change is the artificial sweetener…but i just don’t like that fake flavor taste on my tongue. I was hoping the “ube” would’ve been a more neutral option…food for thought 😁

If you haven't tried it you should! Its delish!

It tastes just like having a sugar cookie!

im ready for my next order

This is one of my favorite flavors. I lobe to blend it with my oatmeal in the morning.

I love the taste of the protein powder.

I really enjoy the flavor of this protein powder and how well it dissolves in water. I drink it after my workouts or when I don’t have time to have a full meal.

Best low cal and carb free protein ever. Best flavor as well.

Love this protein

Once again yummy flavor!

This is by far one of my favorite, I can also get my teenage son to drink it.

Good tasting, dissolved well, add it to my protein shakes

Great taste

Churro is my favorite flavor. I it is especially delicious with coffee and coconut milk as the liquid base.

Tasty, Satisfying and Light
