Jacobs produced test results from another laboratory, Aegis Labs, that tested a separate urine sample from Silva taken 40 days after the commission’s test. It reportedly came back negative for Boldenone, but did show the presence of ATD, a testosterone aid that produces metabolites of the illegal steroid, according to the Aegis doctor who conducted the test.
Jacobs claimed Silva could not have been positive for Boldenone given its extremely long half-life, compared to the relatively short half-life of ATD.
Somewhat ironically, CSAC commissioners raised questions about the chain of custody for Silva’s Aegis sample, which Jacobs could not provide documentation for. Chain of custody was one of the central pieces of Jacob’s defense of Sean Sherk in December of 2007.
Commissioners also noted that Silva could not produce proof that he’d ever purchased the Novidex.
Commissioner Dr. Christopher Giza noted that a level of even 1 nanogram of Boldenone in the body was widely accepted as proof of steroid use, and confirmed that Aegis labs had a more lax standard of testing for the steroid, accepting levels up to 10 nanograms in a test sample. CSAC’s laboratories, Quest Diagnostics and WADA facility Laboratoire De Controle Du Dopage, hold a 1 nanogram standard. Jacobs countered that he was not granted access to those laboratories.
The CSAC did affirm that its WADA laboratory found ATD metabolites in Silva’s “A” and “B” sample taken after the July fight.
At the conclusion of both sides’ arguments, the motion to uphold Silva’s suspension and fine was unanimous.
