Baseball player Marlon Byrd has been suspended for 50 games for a positive test of Tamoxifen which is on the list of banned substances and classified as a performance enhancing drug by Major League Baseball. Tamoxifen increases testosterone and reduces the side effects of steroid use. Byrd has apologized and stated a medication he took for a previous condition resulted in the positive test. Interesting to note though, Bryd had a close working relationship with BALCO founder Victor Conte from 2008 to 2011.
