Natural Products Insider repots that 58 sports supplements have been tested using various chromatography methods, including GC., to test for steroids and stimulants. The study was commissioned and funded by Informed-Choice and conducted by HFL Ltd., a Cambridge, England-based testing lab. Matrix effects prohibited having conclusive data for four samples via LC-MS and six with GC-MS. Of the 52 supplements tested via GC-MS, 13 contained small amounts of banned steroids; LCMS testing on 54 products revealed six contained banned stimulants. The non-peer-reviewed study did not state which supplements were tested, whether they were blinded, where they were purchased, or which products passed or failed.
