Good. dont listen to the chalky taste reviews

Saw reviews of this being chalky or bad taste and left chunks but after trying it. it is definitely not chalky and the taste is perfect. i use the helimix 2.0 vortex shaker and i get absolutely no chunks. for being the first protein powder I've tried ever it's good

It's helped cause I can't eat so much, and I have my meal balanced every meal. In order to stay hydrated.

Great price!

Very tasty and probably mixes the best out of all the powders I’ve tried. Ratio of protein per scoop weight is the best I’ve found so far.
