You cannot prove a negative, only point to those who are more likely clean, usually or for a lifetime. It is easy if you go back 35 or more years. Folks are naive if they think nobody who tested negative ever used. Equally obtuse & agenda driven is the illogical assumption without evidence that everyone must have used. Deterrence never worked, nobody ever avoids PEDs for reasons related to health concerns, getting caught, or has any integrity whatsoever. I hope that this thread does not have such an agenda.
Nobody knows for sure, therefore, you can't answer the question without any certainty. Thank you. But, you do know the fighters that are on (drugs) it.
I don’t think Roberto Duran has ever done drugs...I’ve seen interviews where he warns kids about the dangers of drugs
Arguello Hagler Duran Monzon Pre-prison Tyson (maybe) Certainly not Evan Fields or Vitali/Wlad. Maybe Lewis but i doubt it.
Do you mean PEDs? Arguello was a drug addict. Tyson had his issues with drugs and alcohol, he said fairly early in his career. Duran was a party animal, I wouldn’t be surprised if he did some experimenting. I think PED use has been pretty prevalent in boxing and sports for decades. I don’t know which ones definitely didn’t use, or did use just by looking at their bodies. Sometimes fighters take PEDs and then look like big tubs of goo, like James Toney and Danny Batchedler.
