In February of 2009, Sports Illustrated reported that Alex Rodriguez tested positive for two anabolic steroids, testosterone and metenolone enanthate, while playing for the Texas Rangers in 2003. He claims to have purchased them over the counter, in the Dominican Republic. However, "boli," as he referred to it, is an illegal substance in the Dominican Republic. In an interview with ESPN two days after the SI revelations, Rodriguez admitted to using banned substances from 2001 to 2003, citing "an enormous amount of pressure to perform," but said he had not since then used banned performance-enhancing substances. He said he did not know the name(s) of the particular substance(s) he was using, and would not specify whether he took them in injectable form.
Methenolone enanthate, which has no approved prescriptive use in the United States of America, is the same steroid to which Barry Bonds allegedly tested positive in 2000 and 2001. A weak steroid on its own, it is generally used in conjunction with other steroids. The drug is generally preferred in injected rather than oral form due to its cost.
