Recent Supplement Study?

Hey All,

A friend of mine at the gym told me that there was a recent study done in which a 3rd party evaluated over 100 different supplements/brands. He couldn’t give me any info on how to find the study though. Does anybody know about this study? Was it a good one, or was it one of those things where somebody puts down all of the other brands while putting themselves at the top? Any help will be appreciated.
