An experimental drug that mimics the effect of steroids, such as testosterone, without many of the harmful side effects is freely available online, according to new research. A group from the German Sport University Cologne in Germany detected the compound in a product called Andarine, available online for $100 and labeled as green tea extracts and face moisturizer. The research appears in the current issue of the journal Drug Testing and Analysis.
Mario Thevis, Ph.D., and colleagues, analyzed the advertised substance using state-of-the-art mass spectrometric approaches with high resolution/high accuracy (tandem) mass spectrometry. "One unit (30 mL) was purchased online and delivered in a box labeled to contain face moisturizer and green tea extract. The sealed bottle did not declare any content and no further documents accompanied package," said Dr. Thevis. He went on to explain that LC-MS(/MS) analysis of this solution revealed the presence of S-4 at approximately 150 mg/mL with equal amounts in each container, yielding a total of 4.5 g of the SARM. The active ingredient was identified and characterized by a) its elemental composition (as determined by high resolution/high accuracy mass spectrometry, b) comparison to synthesized reference material regarding retention time and product ion mass spectrum, and c) elucidation of its mass spectrometric behavior. Besides the detection of the active ingredient S-4, a significant amount of byproduct was observed.
