Detection of designer steroids

Abstract

Illicit use of performance-enhancing steroids has proliferated among a wide range of professional and amateur athletes. This problem has attracted broad public attention and has led the United States Congress to draft legislation that proposes frequent testing of athletes. However, current testing protocols are inadequate as athletes can evade detection by using novel steroids that are unknown to authorities. We have developed a strategy that overcomes this limitation by virtue of its ability to detect “designer steroids” without prior knowledge of their existence.
