Steroid chemist Patrick Arnold of Ergopharm testified in San Francisco federal court today in the perjury case against cyclist Tammy Thomas. Pat Arnold said under oath that THG was explicitly created to avoid detection by athletes subject to doping controls. He admitted to selling tetrahydrogestrinone (THG) to Victor Conte of BALCO and directly by mail to Tammy Thomas. (”Chemist testifies he created steroid at the heart of BALCO scandal,” March 25)
THG was also known as “the clear” because it was not detectable at the time Arnold developed it in about 2001.
Under questioning by prosecutor Jeff Nedrow, Arnold said, “That’s the primary reason why THG was developed.”
Arnold also said, “I believe that Miss Thomas understood full well it was undetectable and that that was its purpose.”
He said he believed the cyclist understood the drug had “steroid-like qualities.”
Tammy Thomas denied ever receiving any products from Pat Arnold other than Ergopharm 1-AD; she denied receiving anabolic steroids or other performance-enhancing drugs from Pat Arnold or anyone else; she denied using anabolic steroids.
