Noticed more muscle fullness due I think to the fact that its an isolate.But its not high priced like many others. Mixes very well,although you actually have to put some effort into moving the spoon,i may have a couple tiny clumps. As far as taste and quality, its one of my top three next to Muscle Milk and LEVEL ONE which are twicw as expensive. Not sure why BodyBuilding.com stopped selling this product.
