Paavo Nurmi, winner of 10 Olympic gold medals for Finland in the 1920s, used a drug containing the male hormone testosterone to boost his performance, a Swedish newspaper said.
The national daily Dagens Nyheter published a 1931 advertisement from a Swedish sports daily in which Nurmi and three Swedish athletes of the time recommended the drug Rejuven, which contained testosterone.
Testosterone is the key substance in muscle-building anabolic steroids, which are banned under the anti-doping rules of the International Olympic Committee.

The executive committee of the Federation of International Football Associations met for the first time since last summer's World Cup and rejected Asia's bid for a third spot.
It also banned Iraq from all international games because of its invasion of Kuwait, banned Colombia from playing host to international games because of
drug violence, and kicked Costa Rica out of the 1992 Olympic soccer tournament
because it used an overage player in a youth tournament five years ago.
Julio Cesar Chavez, the unbeaten junior-welterweight champion, got behind Bob Arum's promotional banner by signing a six-fight, $15 million deal.
Arum said Chavez had a contract with Don King for a fight against Meldrick Taylor or Hector Camacho in March, but that Chavez's deal with Arum would not go into effect until May.
Dan Duva, who promotes both Taylor and Camacho, said he had received a letter from Charles Lomax, King's attorney, stating that King was not prepared to go through with a Chavez-Taylor or Chavez-Camacho fight at this time.
Chavez knocked out Ahn Kyung-Duk in Atlantic City on Saturday. He won the International Boxing Federation junior-welterweight title and retained the World Boxing Council version by stopping Taylor with two seconds to go in their bout on March 17.
