Epitestosterone is a natural steroid an inactive epimer of the hormone testosterone. Structurally it differs from testosterone only in the configuration at the OH-bearing carbon C17. Epitestosterone is believed to form in a similar way to testosterone; a 1993 study found that around 50% of epitestosterone production in human males can be ascribed to the testis although the exact pathway of its formation is still the subject of research.
