I recieved my free lb of lemon isolate and I have used it three times so far. I mixed it in water each time and all three times it fully disolved with shaking for aobut 15 seconds. There was also very little foam if any. The flavor was a little light but nice for after a workout when you don't to have a strong tasting protein shake that is way to sweet. All in all I give the lemon isolate 3 out of 4 stars. Also thanks again to Crowler for the free protein.
