research Dehydroepiandrosterone (DHEA) and Testosterone Concentrations in Human Hair after Chronic DHEA Supplementation

12 citations , March 2000 in “Clinical Chemistry”

This study found that a daily dose of 50 mg DHEA only slightly increased the urinary testosterone/epitestosterone ratio for a short period, without exceeding the IOC's acceptable limit.

research Testosterone and doping control

103 citations , June 2006 in “British journal of sports medicine”

This review discusses the use of anabolic-androgenic steroids in sports and outlines current methods for detecting urinary steroid doping, particularly testosterone, but reports no new experimental findings.

research Epitestosterone

59 citations , September 2003 in “Journal of steroid biochemistry and molecular biology/The Journal of steroid biochemistry and molecular biology”

This study suggests that epitestosterone may play a role in regulating androgen-dependent processes like prostate growth and body hair distribution by counteracting testosterone's actions.

Optimization of LC Method for the Determination of Testosterone and Epitestosterone in Urine Samples for Biomedical and Anti-Doping Research

research Optimization of LC method for the determination of testosterone and epitestosterone in urine samples in view of biomedical studies and anti-doping research studies

21 citations , November 2010 in “Talanta”

This study reported the development of a novel and reliable liquid chromatographic method to measure testosterone and epitestosterone in human urine, offering sensitive detection for doping control.
