Unbeaten heavyweight contender Luis "The Real King Kong" Ortiz (28-0, 24 KOs) disputes any claims that he intentionally took any form of banned substance in the past.
The dangerous boxer is getting prepared for the biggest fight of his pro career, when he faces WBC world champion Deontay "The Bronze Bomber" Wilder (39-0, 38 KOs) on Saturday, March 3, from the Barclays Center in Brooklyn, New York.
They were originally scheduled to fight each other last November at the same venue.
The fight was postponed after Ortiz tested positive for a banned substance in a pre-fight drug test.
The WBC conducted an investigation and determined that Ortiz's failed test was connected to the boxer's prescribed medication for high blood pressure. There was already a cloud hanging over Ortiz, because he also tested positive for Nandrolone, an anabolic steroid, following a first-round knockout of Lateef Kayode in September 2014 - which Ortiz claims was administered to him without any explanation of what the drug actually was.
"A lot of people that believe in me and know me well, know that I would not do anything that can jeopardize my future as a boxer. I have too much at stake: my family, my children and the possibility to provide for them," Ortiz said.
"I had been taking that medicine for two years. It was my mistake not to disclose that prescription drug in the paperwork. I never thought a prescription was going to bring me so much trouble. I was taking this medicine to treat high blood pressure, but apparently it's also used to go to the bathroom a lot and mask other things. I drink two gallons of water per day. I go to the bathroom a lot already. I never put two and two together. I'm clean. The dose they found in my system was too low to mask anything at all. If I would have known this prescription drug was not allowed, I would have told my trainer and my doctor.
"I'm a heavyweight I don't need to make weight. Why am I going to go to the trouble of taking an illegal substance that makes you go to the bathroom a lot? I have no need. I simply didn't know it was banned. If I would have known, I would have said something to my trainer or to the doctors.
"I think the fight was not meant to be at that point in time last year. Destiny played a part. It was supposed to be postponed. Now there are no excuses."
