No. They didn't use any banned substances. Sorry but quit talking out of your... esp as a Juventino.
No rules/laws were broken. They "just" took advantage of what was allowed. They used a lot of it.
You can argue it was unethical (for me, it was) but not illegal. Also, there were talks of other clubs doing the same but they only investigated Juve.

Re physical atts, our CL win vs Ajax had more to do with "The Marine," our fitness coach under Lippi.
Conte and Zidane use the same fitness regime, the reason their teams are that fit.
