With the news out about Anderson, I'm wondering if it's even possible to compete at this level w/o PEDs at some point. I'm not talking about being natural for a fight or two. I'm talking about enduring the grind of year in, year out. Drug free. It just does not seem possible that a human body can withstand the kind of intense training in all areas that these athletes require. So, I'm interested to hear from guys who've actually trained intensely in these sports. Is it possible to be drug-free, at or near the top, and still have a long career.
