I KNEW that someone would ask this I just never thought it would be you. Here's your answer though. 
Yes they are all stupid

I guess most of the gurus are too?

Seriously though, you don't think diuretics ever help someone who is very lean? I remember Duchaine talking about meat, how it looks when dried - grainy. He thought losing intramuscular water, which most don't want to do, can make you look freakier. Some competitors, like Dillet when he collapsed, with no veins due to dehydration, looked
freaky hard when near death.

Flex arguably looked his best in 93. Was it due to the diuretic schedule Jeff talked about, or was he just leaner then? Matarazzo almost killed himself with diuretics in the same show. Probably never looked quite like that at any other show.
