Parallel analysis of stimulants in saliva and urine by gas chromatography/mass spectrometry: perspectives for "in competition" anti-doping analysis.
Stimulants are banned by the World Anti-Doping Agency (WADA) if used "in competition". Being the analysis of stimulants presently carried out on urine samples only, it might be useful, for a betterExpand
