PED suspension to Fantasy Viable asset

Just wondering if anyone has any recollection of an RB that got busted for PED’s and returned to be a good fantasy option.

In fact is there any player that got busted for PED’s in any sport that performed near their peak PED use that didn’t end up testing positive again?

The only name that comes to mind is Big Papi from the Boston Red Sox.

Tony Mandarich also comes to mind.
