I recently switched Whey powders after discovering labdoor.com. They test supplements and this one rated very highly. There are several great whey products out there, unfortunately there are many more that are absolute junk. I encourage you to do a bit of research to find out how your protein powder rates. Anyway, I picked the Optimum Nutrition Whey and it's been a great choice. My 16yo son and I both think it taste great, and mixes well. I bought the chocolate flavor. I have tried many whey powders this one is my favorite. I was SUPRISED to find that the last several protein powders I had used were full of fillers and we're spiked with aditives. Especially since the last two were quite expensive. I highly recommend ON Gold Standard.
