Here's a quote from an article about the beginning of Dianabol >
However much Ziegler might have suspected drugs to be critical in the Soviets’ triumph over American lifters in Vienna, his experiments on York musclemen in this period were less than enlightening. He administered testosterone to 1952 Mr. America Jim Park, featherweight champion Yas Kuzuhara, and John Grimek, who recalled how Ziegler tried to convince me that if I took these shots 2 or 3 times a week, I would get stronger and more muscular without training...but I saw no reaction. In fact I told him I was feeling lousy compared to what I feel normally. So he suggested I return to training. I did. But after 6 weeks I gave it up [the shots]. I got no results.17 Nor did Park fare any better. He states that he received only one dose, and its only effect was to give him an instant erection upon seeing any female.18 There is no evidence that Hoffman or anyone else at York saw any potential for the drug. Whether Ziegler became discouraged with the results, feared possible side-effects, or became overburdened with regular patients cannot be ascertained, but he engaged in no further research with muscle enhancing drugs.
