My brother-in-law is a bodybuilder and fitness guy. He does not use any stereoids at all and in fact, he is completely vegan. He might be featured (with my photo) at the cover of a Vegaterian magazine. He also won a competition couple months ago. Those guys work very hard! Pretty cool.
Here is his website: http://www.veganbodybuilding.com – even if you are not vegan, there are tons of diet and fitness related articles there that are very good read.
