I'm curious as to when he was tested in 2003 and what he tested positive for. He testified to never using "Illegal PED's". Many things were still available by law, but not allowed by MLB at the time.
At the hearing, Sosa testified that “everything†he had heard “about steroids and human growth hormones is that they are bad for you, even lethal†and that he “would never put anything dangerous like that†in his body.
“To be clear,†he added, “I have never taken illegal performance-enhancing drugs. I have never injected myself or had anyone inject me with anything.â€
This also happened to Sosa in April 2003.
You can ask any Cub fan, he was never the same after taking that hit. He could never stand close to the plate after that.
That being said, I do think that at some time he might have used PED's , maybe just not ones that were illegal at the time.
