A study says some players on the West Germany team that won the 1954 World Cup may have been injected with the same stimulant given to tank crews and Luftwaffe pilots during World War 2.
Rumors of doping involving the West German team have been around for years.
Some players have acknowledged receiving injections at the World Cup in Switzerland but believed they were given vitamin C.
But a new study by the University of Leipzig says they could have received methamphetamine, which under its trade name Pervitin had been used by Nazi Germany's troops.
"There are indications that they were injected with Pervitin instead of vitamin C," Erik Eggers, one of the authors of the study was quoted as saying by the newspaper Tageszeitung on Tuesday.
West Germany rallied to beat favourite Hungary - led by Ferenc Puskas - 3-2 in Bern and won its first World Cup title in its first post-World War 2 appearance.
The study on the history of doping in Germany was commissioned and funded by the German Olympic committee. It will be completed in 2012.
The first part of its findings were made public this week and disclosed that doping in some sports already took place as early as 1949.
