Also. What's everyones beef with concentrate? Unless you're lactose intolerant concentrate actually has some benefits over pure isolates.
This guy does a good job explaining it....
First generation whey protein powders contained as low as 30-40% protein and contained high amounts of lactose, fat, and undenatured proteins. They were considered a "concentrate" and were used mostly by the food industry for baking and other uses.
Modern concentrates now contain as high as 70-80% plus protein with reduced amounts of lactose and fat. Many people are under the impression that a WPC is inherently inferior to an isolate. This is simply untrue.
Though WPCs will contain less protein on a gram for gram basis than an isolate, a high quality WPC contains all sorts of interesting compounds not found in the isolates.
Good concentrates contain far higher levels of growth factors, such as IGF-1, TGF-1, and TGF-2. They contain much higher levels of various phospholipids, and various bioactive lipids, such as conjugated linoleic acid (CLA), and they often contain higher levels of immunoglobulins and lactoferrin.
Although data is lacking as to whether or not these compounds found in a good WPC will effect an athlete's muscle mass or performance, studies do suggest these compounds can improve immunity, intestinal health, and have many other effects that both athletes and "normal" people alike may find beneficial.
The drawbacks of WPCs are they have slightly less protein gram for gram than an isolate, and contain higher levels of fat (though these fats may in fact have beneficial effects) and higher levels of lactose.
People should not be under the impression that a well made WPC is inherently inferior to a whey protein isolate (WPI) and may in fact be a superior choice, depending on the goals of the person.
For example, some people don't tolerate lactose well or are trying to watch every gram of fat in their diet while others may want the potentially beneficial effects of the additional compounds found in a high quality concentrate.
