The detection of misuse with naturally occuring steroids is a great challenge for doping control
laboratories. Intake of natural anabolic steroids alters the steroid profile. Thus, screening …

The use of anabolic steroids in sports is prohibited by the World Anti-Doping Agency. Until
the 1990s, anabolic steroids were solely manufactured by pharmaceutical companies, albeit …

The use of performance enhancing drugs in sports is prohibited. For the detection of misuse
of such substances gas chromatography or liquid chromatography coupled to mass …

The ionization of 46 anabolic steroids has been studied. The absence of basic or acidic
moieties in most of these analytes makes their direct ionization as [M + H] + by atmospheric …

The detection of new anabolic steroid metabolites and new designer steroids in urine is a
challenge in doping analysis. An approach based on precursor ion scanning for the detection …

The detection of target anabolic steroids in doping analysis has generally been performed
by gas chromatography combined with mass spectrometry (GC-MS). However, liquid …

The collision‐induced dissociation of forty‐one 3‐keto anabolic steroids and related compounds
has been studied using both triple quadrupole (QqQ) and hybrid quadrupole‐time of …

Objective: To assess and compare the prevalence of declared medication, such as
corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), β 2-agonists, narcotic analgesics, …

A method based on liquid chromatography–tandem mass spectrometry (LC–MS/MS) for the
direct quantification of glucuronides of testosterone (TG), epitestosterone (EPG), …

Several precursors of testosterone and nandrolone introduced on the nutritional supplement
market as performance enhancing drugs are banned in sports. Until now they are legally …
