Hoffman (who published Strength & Health) and the boys at York Barbell Club were certainly using them. Test was probably first used by the Russian in the 50s. Ziegler apparently was told about it by a Russian coach at the 54 Weightlifting Championships. He came back to the states are started giving the guys at York test shots and then worked with Ciba to develop Dianabol in 56 which he then gave to the York lifters.
