Chris Colabello says he is still trying to figure out how a banned substance found its way into his urine sample.
Collabelo, who was suspended 80 games by Major League Baseball on Friday, also says the only supplements he takes are certified and provided to him directly by the Toronto Blue Jays strength and conditioning staff.
"I would never, have never and will never compromise the integrity of baseball. Ever. In my life," Colabello said. "And whether that means taking a performance enhancing supplement -- I just wouldn't do it. I don't do it. I haven't done it. I won't do it."
Colabello has gone to extreme lengths to figure out how this could have happened, and that he'll continue searching until he finds an answer.
"I've never called into question the science. That's not my intent," he says. "There's no denying that my urine sample had this DHCMT-M4 metabolite in it. I don't deny that.
"They found a trace amount of metabolite in my urine stream. And that's the only thing I know for a fact. I don't know where it came from. I'm still trying to figure out how it got there. It's all I can do."
