Throughout history? I think many players in the 70s-80s took PEDs without even knowing they were PEDs. Didn't Mcenroe use DMSO to boost his recovery time? He said it helped him, but I don't think DMSO is a banned substance.
I was kinda shocked to read that Mcenroe used DMSO. I have used in chemistry lab so many times before.
