Quantification of the Carboxylated LGD‐4033 Long‐Term Metabolite in Human Micro‐Dose Excretion Study Urine Samples

open access: yesDrug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled the first quantitative determination of the LGD‐4033 long‐term metabolite (M5‐b) in urine following controlled micro‐dose administration. The generated urinary reference data support the interpretation of adverse analytical findings and anti‐doping result management. ABSTRACT Selective androgen receptor modulators (

Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

open access: yesDrug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...
