I'm not saying Federer is clean at all. He is my favourite player, but he's been fortunate not to have the same injury problems as Nadal.
A lot of it has to do with his game and technique is just less taxing and his body, other could be he has more natural talent.
Nadal's game would probably induce him to use some drugs to recover. IDK.,
