General description

Epitestosterone is a stereoisomer of the hormone testosterone. Epitestosterone is often used to illicitly mask high testosterone levels in athletic drug tests. This Certified Snap-N-Spike® Solution is applicable for use in LC/MS or GC/MS applications for sports testing, urine drug testing or forensic analysis.

Application


  • Anti-doping analysis: Epitestosterone serves as a critical analytical reference in anti-doping, particularly for correcting urinary testosterone to epitestosterone ratios in athletes, ensuring accurate and fair sports testing practices (Martínez Brito et al., 2023).

  • Steroid hormone profiling: In biochemistry, epitestosterone is utilized in profiling steroid hormones, aiding in the study of hormone balance and endocrine disorders (Xu et al., 2023).

The validated micellar electrokinetic chromatography (MEKC) was proposed for the determination of five steroid hormones in human urine samples. That technique allowed for the separation and quantification of cortisol, cortisone, corticosterone, testosterone, and epitestosterone and was sensitive enough to detect

The screening of testosterone misuse in the doping control field is normally performed by the measurement of the ratio between the concentrations of testosterone and epitestosterone excreted as glucuronides (T/E). Despite the satisfactory results obtained with this approach, the measurement

Testosterone and other anabolic-androgenic steroids enhance athletic performance in men and women. As a result, exogenous androgen is banned from most competitive sports. However, due to variability in endogenous secretion, and similarities with exogenous testosterone, it has been challenging to

A simple and accurate liquid chromatography/tandem mass spectrometry (LC/MS/MS) method has been developed and validated for the quantitative determination of ephedrine, pseudoephedrine, methylephedrine, cathine, salbutamol, morphine and epitestosterone in human urine. Urine samples were spiked with internal standard and diluted
