17α-Benzoyloxy Testosterone is an intermediate for the synthesis of 17-epi-Testosterone (T155005). Testosterone and epitestosterone are endogenous steroids that differ in the configuration of the hydroxyl-bearing carbon at C-17. Testosterone is the predominant male sex hormone, whereas the role of epitestosterone is largely unclear. In humans, both androgens are excreted mainly as glucuronide conjugates.
