What Did Canelo Alvarez Reveal About His Teammate’s PED Scandal? Shocking Message That Has Fans Buzzing!

In the aftermath of Jaime Munguia’s positive drug test, boxing superstar Canelo Alvarez has finally broken his silence. Known for his fiery personality and no-nonsense attitude, Canelo didn’t mince words when asked about his fellow Mexican boxer’s shocking PED scandal.

The news comes as a significant blow not only to Munguia’s reputation but also to the growing scrutiny surrounding Eddy Reynoso’s training camp, which has now seen multiple fighters embroiled in doping controversies.

Jaime Munguia Tests Positive for Exogenous Testosterone Metabolites

On May 29, 2025, reports surfaced that Jaime Munguia tested positive for exogenous testosterone metabolites following his May 4th bout against Bruno Surace. Munguia, who lost a unanimous decision to Canelo Alvarez earlier that night, now finds himself at the center of a doping controversy that could derail his rising career.

If the B-sample confirms the positive result, Munguia’s win over Surace will likely be overturned into a no-contest, and he could face a suspension of up to one year.

Munguia Responds: ‘Complete Surprise to Me’

Munguia wasted no time responding to the doping allegations. On May 30, he took to social media to share his thoughts:

“Throughout my boxing career, I have undergone numerous anti-doping tests and have never tested positive.
I was tested twice during this training camp, and both results came back negative, which is why receiving this notification of an adverse finding has been a complete surprise to me.”

He added:

“Several experts have explained that there are multiple ways contamination can occur, and I am fully willing to undergo any retroactive, current, or future testing to demonstrate that I have always been a clean athlete.”

Munguia’s statement aims to shift the narrative toward accidental contamination, a common explanation in doping defenses. But given the growing history of fighters under Eddy Reynoso testing positive, many in the boxing world are skeptical.

Canelo Alvarez: ‘Only He Knows What Happened’

When asked about Munguia’s drug test during a media appearance on May 30, Canelo Alvarez gave a blunt and revealing response. Speaking in Spanish, later translated to English, Canelo stated:

“I am with [Munguia] 100%, but only he knows what happened.”

While the statement shows solidarity, it also subtly distances Canelo from the controversy, indicating that only Munguia can truly account for his actions. This could be a calculated move to protect his own brand, which has previously come under fire for similar reasons.

Canelo Defends Eddy Reynoso: ‘Eddy Doesn’t Give Him His Food’

Perhaps the most intriguing part of Canelo’s statement was his defense of longtime trainer Eddy Reynoso, whose gym has now seen multiple fighters test positive for banned substances.

“Eddy doesn’t give him his food,” Canelo said, addressing speculation that Reynoso could have contributed to the failed test.

This is a clear effort to exonerate Reynoso from the scandal. With Canelo, Ryan Garcia, Oscar Valdez, and now Munguia all having dealt with PED allegations while under Reynoso’s wing, questions are swirling about whether the environment fosters clean sport.

By pointing out that Reynoso has no control over his fighters’ dietary intake, Canelo attempts to isolate the blame and prevent further tarnishing of his trainer’s reputation.

A Pattern Emerging Under Eddy Reynoso’s Camp?

The most damning aspect of this controversy is the emerging pattern of PED infractions associated with Reynoso’s gym:

• Canelo Alvarez tested positive for clenbuterol in 2018, blaming contaminated meat.

• Oscar Valdez failed a test for phentermine in 2021 but was still allowed to fight.

• Ryan Garcia tested positive for ostarine earlier in 2024.

• Jaime Munguia now tests positive for exogenous testosterone metabolites in 2025.

Critics argue that this string of positive tests paints a troubling picture. Even if each incident can be explained away individually, together they suggest a larger issue of oversight or systemic problems within the camp.

Canelo’s Own PED History Still Haunts Him

In 2018, Canelo Alvarez tested positive for clenbuterol, a substance that stimulates the heart and central nervous system, during pre-fight testing ahead of his highly anticipated rematch with Gennady Golovkin. The result was a six-month suspension and the fight being postponed to September.

Canelo insisted the substance entered his system due to tainted meat he consumed in Mexico, a defense that was widely debated. Despite returning to the ring with dominant performances, critics and rival fighters have continued to question his legacy.

These historical controversies only magnify the impact of Munguia’s failed test, especially since Canelo’s credibility is tied to Reynoso, who also trains Munguia.

Is Boxing’s PED Problem Growing Worse?

Performance-enhancing drugs in boxing have long been a thorny issue. While organizations like VADA (Voluntary Anti-Doping Association) and WADA (World Anti-Doping Agency) enforce anti-doping protocols, fighters and trainers continue to find ways to evade detection.

Recently, Jermall Charlo accused Canelo Alvarez of ongoing PED use, stating:

“They make the drug at the limit of non-responsive. They’ve been doing that sh*t for years.”

Charlo’s inflammatory remarks suggest that PED usage isn’t just a case-by-case issue—it’s a systemic problem fueled by money, power, and influence in the sport.

Fighters Remain Silent—Or Fearful

Jeff Mayweather, uncle to boxing legend Floyd Mayweather, added to the controversy when he claimed that fighters don’t ask Canelo to undergo stringent testing out of fear:

“They’re afraid that pushing for drug testing might cost them the fight—and with it, their biggest payday.”

This adds a chilling dimension: the very structure of the sport may discourage transparency, with many fighters prioritizing career-defining paydays over fair play.

What’s Next for Jaime Munguia?

If Munguia’s B-sample confirms the initial result, he could face a year-long suspension, and his victory over Bruno Surace would be ruled a no-contest. Such a setback would be devastating for a fighter who was just beginning to find momentum after facing Canelo.

It would also likely delay any major fights Munguia may have been lining up for late 2025 or early 2026. Worse, it could taint his name among promoters and sponsors, making future opportunities harder to secure.

Canelo Alvarez: Caught in the Crossfire Again

Whether he likes it or not, Canelo Alvarez remains at the center of the PED debate in boxing. His past, his association with Reynoso, and now his comments about Jaime Munguia’s positive test all keep his name entangled with the sport’s darkest issue.

Despite his efforts to separate himself and Reynoso from the scandal, the optics are increasingly difficult to ignore. More voices are calling for year-round, random testing and stricter consequences for failed tests.

Can Reynoso Regain Credibility?

While Eddy Reynoso is one of the most respected coaches in boxing, the frequent PED controversies under his watch are damaging his legacy. Canelo’s defense—that Reynoso doesn’t control his fighters’ meals—is unlikely to satisfy critics who believe the head trainer should be responsible for maintaining a clean program.

Moving forward, Reynoso may need to publicly address the issue, potentially by inviting more frequent VADA testing for all fighters under his wing.

Conclusion: The PED Problem Isn’t Going Away

The latest news involving Jaime Munguia’s positive drug test, combined with Canelo Alvarez’s response, highlights the growing and uncomfortable truth: PED usage remains an unresolved problem in boxing. Whether through contamination, negligence, or intentional abuse, the sport continues to grapple with trust and fairness.

Canelo’s loyalty to Munguia and Reynoso is commendable, but fans and fighters alike deserve more than vague reassurances. It’s time for boxing’s biggest names to take leadership roles in pushing for transparency, reform, and clean sport.

Until then, the shadows of suspicion will continue to hang over even the brightest stars in the sport.
