"I am truly shocked by what has happened and I lament that this has caused people to have doubts about my integrity. I have always been a clean fighter," Alvarez said in a statement released by Golden Boy Promotions.
Addressing the press, Canelo added: "I first got the call from Eric Gomez - 'you tested positive. My first reaction was, 'there has to be a mistake.'
"I am sad and feel powerless that this fight can not happen now. I have nothing to hide. I want to be transparent.
"I will do whatever I need to do to demonstrate I have never (intentionally) taken this substance. I have always operated as a clean fighter. I have always taken clean substances.
"I respect the sport unconditionally and would never do anything to tarnish something I have given so many sacrifices for. It saddens me that people are accusing me of doing something improper.
"From here on out, I will take increased precautions to ensure this will never happen again. This hit me hard. If it helps other athletes to clear their name. I wish it hadn't been me."
On Golovkin's damning media conference on the situation, the two-weight world champion said: "What Golovkin or his team say does not bother me at all. They're not experts, doctors."
