Synthetic testosterone itself would be developed in the 1930’s. The first batches of testosterone manufactured would have no ester attached (Testosterone Suspension) and needless to say would be fast acting and require very frequent injections. In 1937 the first ester controlled testosterone would hit the market thanks to Schering and their new Testosterone Propionate product.
