About 3-epi-Androsterone :
3-epi-Androsterone  is a steroid hormone with weak androgenic activity. It is a natural metabolite of dehydroepiandrosterone via the 5-alpha reductase enzyme. It was first isolated in 1931, by Adolf Friedrich Johann Butenandt and Kurt Tscherning. They distilled over 17000 litres of male urine, from which they got 50 milligrams of crystalline androsterone (most likely mixed isomers), which was sufficient to find that the chemical formula was very similar to estrone.
