This thread is titled "For all those NEW people asking about clen....".
Mastering the art of Google and posting studies doesn't really touch on the above. Its great food for thought and we human minds love to add ridiculous amounts of knowledge to our primitive minds. However, none goes to answering the simple question of "do these noobs need clen?". The answer to that question is probably no.
If they are serious about one day competing, then down the road perhaps that answer changes. But for those reading this now, all of those studies posted doesn't mean its fine to take clen. The thread just got sidetracked into a technical discussion.
