By Drostanolone ( aka masteron ) is one of the most common anabolic androgenic steroids in doping tests. If you are a performing athlete and decide to buy Masteron to apply it on the course, this article will tell you how many days it is worth stopping the use of the drug to avoid problems in doping tests.
In the study described below, scientists examined the metabolic profiles of drostanolone in urine using tandem quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) liquid chromatography methods in full scan mode and targeted detection of MS / MS with accurate mass measurement.
The study involved one healthy male volunteer who had been injected with masteron steroid in USA, and liquid-liquid extraction was used along with direct injection analysis to analyze urine samples. Chromatographic peaks of potential metabolites were identified with an estimated [MH] (-) as the target ion in the full scan study, and deprotonated ions were analyzed in the MS …
