I really enjoy the taste of Genisoy Soy Protein Shake Fat Free. Great taste and it is fat free. I have my whole family drinking this just to help deal with the heat. Great flavors and it mixes well. I just wish it did not give me gas.

I bought Genisoy Soy Protein Shake Fat Free on something of a whim - I like some of Genisoy's other products - and was worried that it would be terrible. But it really isn't bad!  
 
The instructions read: For best results, add 1 scoop of powder to 8 oz. of protein fortified nonfat milk and mix in an electric blender, or in a shaker. Can also be mixed with water or other beverage of choice. I didn't want the extra added calories of the milk - plus I'm lactose intolerant, so I went ahead and mixed it with water, worried it would be bland. It was pretty tasty. The reason they say to put in a blender or shake is because it's difficult to mix - it gets very thick.  
 
Genisoy Soy Protein Shake Fat Free has Kosher status but it isn't clear here, but it's got a circle-K hechshar, if this is relevant for you. And this particular product has many more vitamins and mineratals than the Genisoy Ultra XT product. I'm going to go out and get the vanilla, too. Definitely recommended!

The first time I tried Genisoy Soy Protein Shake Fat Free, I mixed it with skim milk in my personal blender. The taste wasn't too horrible but it was kind of chalky, and it smelled like something very funny?? The flavor could use more chocolate as well to really make it seem authentic. Then I blended it with Silk Vanilla Soymilk, one of my all time fsavorites and no smell! It's comparable to Slim-fast with less sugar, less carbs, and more protein. It also tastes better ice cold.
