Chris Aceto Denies Rumor That Derek Lunsford Used PMMA Injections to Win 2025 Mr. Olympia

Aceto acknowledged the video and online chatter. He said people repeatedly mentioned Lunsford’s name. He said that repetition alone forced him to respond.

“I don’t know what it is, but I know Derek Lunsford did not use it,” Aceto said.
“Someone sent me a video today of accusations about Derek Lunsford. His name was mentioned over and over and over.”

Next, Aceto escalated his response. He did not call the rumor misleading. He called it false.

“I will tell you that it’s a lie,” he said.
“Can I make it any more explicit that it’s a lie?”

Then, Aceto explained why the wording mattered. He said calling something “alleged” does not remove responsibility from the speaker.

“The allegations — it’s not allegations, it’s accusations,” Aceto said.
“I don’t care how many times you use the word ‘alleged.’ It doesn’t mean you’re not making the accusation.”

Aceto Shuts Down Any Speculation About Competition Use

Aceto addressed the timeline directly. He said the rumor implied repeated use across competitions. He rejected that entirely.

“There’s an accusation directly against Derek,” Aceto said.
“Did Derek use it for the Arnold? Did Derek use it for the Olympia? No.”

Next, he clarified that he would never associate his reputation with unethical practices. He said he would not allow that implication to stand.

“If someone wants to accuse me or Derek of something like that, then they better be prepared to back it up,” he said.
“Because that’s not how this works.”

Then, Aceto emphasized that bodybuilding already faces enough scrutiny. He said false claims only undermine legitimate discussion.

“People throw things out there without understanding the consequences,” Aceto said.
“And once it’s out there, you can’t take it back.”

Lunsford’s Olympia Win and the Aftermath

Derek Lunsford’s 2025 Mr. Olympia win marked a return to the top. He reclaimed the Sandow Trophy after losing it the year before. The victory came against an elite field.

Next, Aceto said Lunsford’s preparation involved adversity. He cited physical setbacks and intense pressure heading into finals. He said none of it was hidden.

“This wasn’t an easy prep,” Aceto said.
“There were things he had to deal with that most people don’t even know about.”

Then, Aceto addressed speculation about Lunsford’s future. He dismissed the idea that money could shift his priorities.

“Even if the Arnold paid a million dollars, it wouldn’t change anything,” Aceto said.
“The goal is the Olympia. That’s always the goal.”
