How is "% less" worked out?
We divide each container's price by the amount of active ingredient its label says it holds, then compare that price per 25 g protein. It is our comparison, not a store sale. The store sets the price at checkout.
Is a cheaper whey isolate the same as Dymatize?
We compare the labeled amount of the active ingredient, not quality, taste or testing. Each row shows any third-party testing we found. We don't test products and don't tell you what to take.
