### ⭐⭐⭐⭐⭐ 







  
  
    Tastes great and is effective
  

*by J***E on Reviewed in the United States on October 2, 2020*

I have a hard time with most proteins. The flavors get old, boring, and whey gives me a little nausea occasionally, especially with the cheaper stuff. This stuff is the opposite. It tastes amazing (like drinking cake batter), and I don’t feel strange after drinking it. I take it both post workout and before bed. I love it. If you get it on sale it’s a great value. I’ll continue buying it over their competitors.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Value, Great Product
  

*by Z***H on Reviewed in the United States on September 22, 2020*

Great tasting blend of casein and whey, great value for the money. Excited for the two new flavors they just added...and it just plain works. When compared to other blends or making one on truenutrion.com, this one exceeds those in value and quality. Chris Duffin is a guy who has always done his homework and this product is an example of that. Thanks.

### ⭐⭐⭐⭐⭐ 







  
  
    One of the best on the market!
  

*by D***G on Reviewed in the United States on July 24, 2020*

Great tasting, good nutritional profile, perfect mix of fast and slow digesting proteins.  Quality company and product. I purchased the vanilla flavor.
