Mixes well and the flavors are good considering the lack of sweetener. I also like the bulk of the 4lb container, but wish the bulk would be offered in a larger variety of flavors

Tastes GREAT!

I ordered 100% grass fed whey protein isolate in chocolate, in the giant 4lb tub. I've never tried this before so I was worried about the taste. I'm relieved to report that this tastes GREAT!!! Almost too good, actually. Using a little battery powered coffee stirrer didn't have enough power so I drug out the electric hand mixer, and BLAM!!! 8 ounces of milk and one scoop later and my football/baseball/wrestling son was very happy! Thanks Transparent labs. This stuff is great!!!

Damn near perfect

I love this stuff. Almost pure whey protein isolate. My only concern is the sunflower lecithin is not organic. The organic stuff isn't that expensive so I hope in the future they offer that recipe. Other than that adding this protein to my diet literally healed my shoulder. I work out too much and needed something that wasn't filled with additives. I appreciate this stuff so much. I feel great lately so this was just what I needed. But again, an organic option would be perfect. I'll still give this 5 stars as I couldn't find anyone else to offer my perfect recipe. Glass container would also be nice but frankly I get not wanting to mail glass. Great work team
