Up till now I was using GNC 100% whey chocolate flavor. It didnt taste that great but it was no trouble getting used to it. But today arrived my new shipment of supplements which contained 100% whey powder made by Optimum Nutrition. I got 5lbs of double chocolate and 5lbs of chocolate mint. I opened the chocolate mint first and am sippin it now. I gotta say this stuff tastes pretty friggin good. You all might consider giving it a try sometime. Its good enough tasting that sipping is enjoyable. Now the GNC stuff, I would just chug that just to get it over with. So long GNC....i found a new supplier.
