I think roy juiced no proof but he moved up alot on a small frame, holyfield possibly at times especially bowe holy 2 he put on 17 pounds of muscle not fat but... Evander never gained weight fast even in the transiiton from cruizer to heavy it took a year and not 6 months so i dont know, evander was muscualr but not huge so its difficult to say, you could argue if holy took stroids hed be 240 kind of like ibeabuchi, others toney, possibly tyson at times, hercules wever, ken norton but just guesses
