He wasnt actually qualified in anyway to discuss people's health with them in terms of what drugs they should be taking though was he so it was acedemic surely?
As far as im aware he has no medical background at all, and his own "knowledge" was limited to a very small amount of trial and error with his own body.
People's bodies can vary in immensely subtle ways and it would be very easy for someone well meaning to actually give out fatal advice.

Without a doubt banning him was the right thing to do in light of him selling illegal drugs on here, but its a shame as I did like the guy and find his posts interesting and I know he inspired others, Benni for example I believe is hitting the gym hard now and making good progress largely as a result of chatting to him, and that side of his input to the forum being gone is a shame.
