I think this is the best whey protein of ultimate nutrition series.i am saying this thing because this is an american brand which is cheaper than any other american brands of whey.it comes in the minimum 5.28lb weight and available in many flavours like strawberry, vanilla creme, chocolate creme, delicious raspberry and many more.in now date it costs around 4.5k-5k which is far better than other brands of whey protein.one serving size is 30g and from which 25g is protein so this is the best you can get from it.quality wise also its good and one should buy it if his/her main goal is lean muscle building.from my side thumbs up for this product.
