I refuse to use any other protein anymore. This doesn't leave an aftertaste in my mouth, the flavors are delicious and there are zero fillers/processed ingredients. A true 10/10
Nick Yousef
Best protein i have tried. Doesn't give you the bloat feeling like others and mixes well in liquid. Odins blend is my favorite right now. If you are a coffee lover then Java over ice is the bomb.
Nicolé Douglas
I love the taste and how well it mixes. I use the chocolate and vanilla for my smoothies. The Natural is great for cooking. And, it doesn't mess with my stomach. Great source of protein.
Regina Erickson
Love this protein! so smooth with no gritty taste.
Sarah Guerrero
Delicious protein! There are multiple flavors to choose from and it dissolves so well. My personal favorite is the Odin Blend, if you like chocolate peanut butter and this one is definitely top tier!
Haley Erickson
We purchased a bag of single serving pouches. This came with vanilla, chocolate, natural, and java. Good quality protein, not too sweet and mixes well. Most importantly, VETERAN owned! Woof!
