You see the guys on stage and your brain just short-circuits. They look like they’ve been carved out of granite, with shoulders the size of bowling balls and skin so thin it looks like Saran Wrap stretched over a bag of walnuts. It’s superhuman. Naturally, the first thing anyone asks is the big one: Are steroids allowed in Mr. Olympia? The answer is a messy, complicated "no, but also kind of."
If you look at the rulebook for the IFBB Professional League—the body that runs the Olympia—you’ll find language about following the World Anti-Doping Agency (WADA) guidelines. Technically, steroids are a "prohibited substance." But if you’ve ever spent five minutes in a gym, you know that the physiques standing on that Vegas stage are physically impossible to achieve on chicken, broccoli, and a good night's sleep.

The 1990 Experiment: The Year the Olympia Almost Died
To understand why the Olympia is the way it is today, you have to look back at the disaster that was 1990.
For the first and only time in the history of the main event, the IFBB decided to actually enforce drug testing. They brought in WADA-style urinalysis. The result? It was a total train wreck.
Several top-tier athletes failed. Some of the biggest names in the sport showed up looking "flat" or significantly smaller because they had to cycle off their gear to pass the test. The fans hated it. The "wow factor" was gone. The atmosphere felt more like a local YMCA meet than the pinnacle of human muscularity.
After that, the organizers realized something uncomfortable: people don't pay for tickets to see "average" guys with great genetics. They pay to see "monsters." The testing was quietly shelved for the Open Division the following year.
Since then, the unspoken agreement has been: don't get caught with it backstage, and don't make it a legal problem for the federation.
Wait, Does the IFBB Test Anyone?
Here is where it gets confusing. The IFBB does have a "Natural" division.
In the IFBB Pro Natural contests, the testing is intense. We’re talking urinalysis for anabolic agents, diuretics, and masking agents. Sometimes they even use polygraph tests (lie detectors) to see if you’re being honest about your history. If you fail there, you’re looking at a one-year suspension for a first offense and a lifetime ban if you’re a repeat offender.
But here’s the kicker: winning a Natural Pro show doesn't qualify you for the main Mr. Olympia stage. It’s a completely different track.
For the main event—the one where guys like Derek Lunsford, Hadi Choopan, or Chris Bumstead compete—there is no regular, rigorous drug testing for steroids. They do occasionally test for diuretics, but that’s mostly a safety measure to prevent athletes from dropping dead of heart failure due to extreme dehydration on stage.
The Difference Between "Allowed" and "Not Tested"
If you walked up to an official and asked, "Can I take Trenbolone?" they’d tell you no. It’s technically against the code.
But there’s a massive gap between a rule existing and a rule being enforced. Honestly, the Mr. Olympia is more like the "untested" federations in powerlifting. Everyone knows what’s happening. The judges know. The fans know. The athletes—many of whom, like Jay Cutler or Arnold Schwarzenegger, have spoken openly about "medical supervision" or past usage—definitely know.
Arnold famously told ABC News back in 2005 that steroids were "something new" and they did them under a doctor's care. Today, it's less of an experiment and more of a science.
Why don't they just legalize it?
Legalizing it would be a PR nightmare.
- Legal Issues: Anabolic steroids are Controlled Substances in the US (under the Steroid Control Act of 1990). A major sporting organization can't "allow" an illegal act.
- Sponsorships: Big-name supplements and mainstream brands need a layer of plausible deniability to stay involved.
- Insurance: Insuring an event that explicitly encourages drug use is almost impossible.
So, they stay in this "grey zone." The rules say no, but the stage says yes.

The Health Cost Nobody Talks About
We can't talk about steroids in the Olympia without mentioning the toll. The last few years have been rough for the sport. We’ve seen a string of premature deaths in the bodybuilding community—names like Shawn Rhoden and George Peterson—that have forced the IFBB to at least pretend to look at health screenings.
They’ve started emphasizing "health over sheer mass" in some judging criteria, but as long as the biggest guy with the craziest conditioning wins, the incentive to use Vitamin S (steroids) isn't going anywhere.
The pressure is insane. To get that "dry" look, athletes aren't just using testosterone. They’re using:
- Clenbuterol for fat burning.
- Human Growth Hormone (HGH) for recovery and size.
- Insulin (which is incredibly dangerous if timed wrong).
- Diuretics to shed every last drop of water between the skin and muscle.
Real Talk: Can You Win "Natty"?
Short answer: No.
You can have the best genetics in the world. You can train until your joints scream. But the human body has a "myostatin" limit—a biological ceiling on how much muscle it can carry. The men on the Olympia stage aren't just at the ceiling; they’re on the roof of a completely different building.
If you’re looking for drug-free competition, you have to look at organizations like the INBA/PNBA (International Natural Bodybuilding Association). They take testing seriously. They strip titles. They post a "Wall of Shame."
But the Mr. Olympia? That’s the "Open" world. It’s the Formula 1 of the human body. Just like you don't expect a Honda Civic to compete with a Ferrari, you can't expect a natural athlete to stand next to a 300-pound pro.
Actionable Takeaways for the Average Lifter
If you're following the Olympia and wondering how this affects your own fitness journey, keep these things in mind:
- Adjust Your Expectations: Do not compare your 18-inch arms to a pro’s 23-inch peaks. They are playing a different game with different "supplements."
- Focus on Longevity: Most pro bodybuilders pay a heavy price later in life. If you aren't getting paid six figures to be a giant, the risk-to-reward ratio for PEDs is usually terrible.
- Bloodwork is King: If you ever do decide to go down a "hormonal" path (even just for TRT), never do it without a real doctor and regular blood panels. "Bro-science" from a guy at the gym is a fast track to kidney issues.
- Natural is the New Flex: In 2026, the "Natural" look is actually more popular for the general public. Being lean, functional, and healthy is a much better long-term goal for 99% of us.
The Mr. Olympia remains the ultimate spectacle of what the human body can do when pushed to the absolute limit of science and willpower. Just don't let the lack of "testing" fool you into thinking the path to that stage is paved with nothing but hard work and protein shakes.
To stay informed on how the IFBB is changing its health protocols this year, you should keep an eye on the official IFBB Pro League updates regarding athlete health screenings, which are becoming more frequent even if "steroid testing" remains in the shadows.
