When Did Bodybuilders REALLY Start Using Steroids?

When did bodybuilders start using steroids, and were the silver era legends natural? This video follows the evidence year by year, from the first synthetic testosterone in 1935 to the York Barbell experiments of the 1950s and the arrival of Dianabol in 1958. It covers fake hormone products of the 1940s, the myths about Nazi steroids, Dr. John Ziegler's 1954 encounter in Vienna, and the isometrics cover story at York. It also names the first bodybuilders on record to take testosterone. Steve Reeves, John Grimek, George Eiferman, Leroy Colbert, Marvin Eder and Jim Park are each checked against what the historical record actually shows.
