MET-Rx Ultramyosyn Whey Isolate is an ultra premium protein designed to provide optimum support for lean muscle, strength and exercise recovery. Ultramyosyn Whey Isolate contains protein that is processed using microfiltration to ensure an isolated whey that contains a minimum of 90% protein with minimal lactose and fat. These isolation processes separate the valuable protein from non-protein materials yielding a highly-purified whey isolate. MET-Rx Ultramyosyn Whey Isolate provides all of the benefits whey protein is known for and more, by carefully removing the fat and lactose that you don't need while increasing the percentage of aminos as compared to regular whey concentrate.
