Enodogeneous testosterone, testosterone precursors and metabolites: 19 Nor-steroids and establishment of normal urinary levels of these related compounds

Project Title: Enodogeneous testosterone, testosterone precursors and metabolites: 19 Nor-steroids and establishment of normal urinary levels of these related compounds

Researchers: E. Al-Dujaili (Queen Margaret University College, Scotland) I. Mason, M. Sharp (University of Edinburgh, Scotland)

Year accepted: 2002

Summary: Two clinical studies were performed on normal healthy volunteers who were known not to have taken anabolic steroids. The first one aimed to establish normal ranges for urinary nandrolone and testosterone levels in non-exercising subjects and those who routinely exercise for leisure purposes. The second study investigated the effect of a controlled single bout of exercise on urinary levels of endogenous nandrolone, free and total testosterone in female and male volunteers.
