Great Protein Powder

I really enjoy the caramel powder. I've had in coffee & almond milk and enjoy both. It mixes well, isn't chalky, and has a great, non-chemical/fake taste. I am excited to try other flavors.

Decadent fudge taste and consistency!

If you love a rich, fudgy chocolate taste whether you mix with water or a type of milk, this is the flavor for you! It always comes out tasting like a milkshake and pair it with some peanut butter, you won't regret it! Love the quality and that it doesn't taste 'proteiny'. On top of it all, they ship so quickly. Will be a repeat customer!
