In this work, a stable isotope labelling-flow injection analysis-tandem mass spectrometry (SIL-FIA-MS/MS) with simultaneous monitoring [M+H] + and [M+Cl]-method was developed for very specific and high throughput screening of anabolic-androgenic steroids (AAS) illegally added to healthy foods. Initially, a simple centrifugation step was carried out for liquid samples, and for solid samples, a . This paper describes a simple and effective qualitative gas chromatography-mass spectrometry (GC-MS) method to detect anabolic androgenic steroids (AAS): androsterone, nandrolene, dehydroepiandrosterone, 5ɑ-androstane-3β, 17β-diol, dihydrotestosterone, testosterone, methenolone acetate, methandienone, boldenone and fluoxymesterone, in food suppl. In recent years, anabolic androgenic steroids (AASs) have been frequently detected as undeclared ingredients in dietary supplements, where the adverse analytical findings (AAFs) were obtained from analysis of athletes' urine samples after ingestion.

Anabolic androgenic steroids (AAS) make up one of the most prevalent classes of performance-enhancing drugs banned by the World Anti-Doping Agency (WADA) due to the competitive advantage they can afford athletes. The anabolic action of the steroid hormones has gone through a period of great activity in both basic and clinical research. A complete understanding of the manifold anabolic effects still remains to be elucidated and the art of clinical application is only gradually becoming apparent. This volume should be useful not only to the experienced .

AuthorsSimultaneous detection of 93 anabolic androgenic steroids in dietary supplements using gas chromatography tandem mass spectrometry - ScienceDirect Journal of Pharmaceutical and Biomedical Analysis Volume 211, 20 March 2022, 114619Anabolic steroids (also known as androgenic steroids) are synthetic derivatives of testosterone. Legal, as well as the illegal use of anabolic steroids, is gaining popularity. There are two types of anabolic steroids: 1) 17 alpha alkyl derivatives: e. g. , oxandrolone, oxymetholone, and fluoxymesterone; and 2) 17 beta ester derivatives: e. g . Introduction The presence of anabolic-androgenic steroids (AAS) in illegal commercial products has been pointed as a global threat for public health. Due the correlation with adverse toxicological effects, there is a growing interest in the implementation of straightforward methods for the determination of AAS in seized products. GC-MS retention time Aim: This study aimed to investigate the gas chromatographic properties and mass spectrometric fragmentations of anabolic androgenic steroids (AASs) after trimethylsilylated derivatization. Materials & methods: A total of 113 AASs were analyzed through gas chromatography-mass spectrometry in the full-scan mode. Anabolic androgenic steroids (AAS) make up one of the most prevalent classes of performance-enhancing drugs banned by the World Anti-Doping Agency (WADA) due to the competitive advantage they can afford athletes. Anabolic-androgenic steroids (AASs) are very potent muscle builders, and professional sportsmen often take protein supplements to improve their performance. . anabolic-androgenic steroids in protein supplements using QuEChERS extraction followed by liquid chromatography-tandem mass spectrometry Food Addit Contam Part A Chem Anal Control Expo . Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are synthetic substances that mimic the effects of testosterone, the male sex hormone. They are used to increase muscle size, strength, and performance and are commonly associated with athletic performance enhancement and bodybuilding. Anabolic steroids are classified as . Anabolic androgenic steroids are the best-known class of PEDs in the sporting world. They are powerful mimics of the male sex hormone testosterone, and hence have major anabolic physiological actions such as increased muscle mass and strength. .
