Arnold changed his calves though, thereby changing his proportions a bit
Yep that usually comes up when discussing this topic. Though I don't think Arnold's calves were ever really that bad from what I remember seeing and he obviously had great attachments and the fibers must have been there. But anyways the exception confirms the rule!

And pellius did miraculously improve his calves

I think I remember Serge actually coming on here and posting that he was slowly being poisoned by his ....daughter? Was it here? This is the only BB related board I visit and back in the day I still only visited a couple of others.
Now that you mention it I do remember that but I don't remember where I saw it either. Now I also remember that Serge went into a coma and then some from France claimed it was an insulin OD. Just a rumor AFAIAC. Maybe Serge was still using speed and in an amphetamine psychosis when he talked about poisoning LOL. Serge had told someone on promuscle he used speed when he was on top, as did many of the others back then.
