17-epi-Testosterone-d3 is the labelled analog of 17-epi-Testosterone.Testosterone (T155000) and epitestosterone (T155005) 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.
