When it comes to quality of a product, you have to think about the process it goes through to create it. That process can make more break a
product because it will destroy its bioavailability. That's the same reason I don't buy bulk protein cheap at a pharmacy. Your body probably won't recognize the majority of the proteins your ingesting because of the process that created it. This theory can be applied to the process of all supplements we take and how our body is able to use them, including the power chews at mr supps. Quality really does matter. Hope that helps.
