Is Mike O’Hearn on steroids?

Then you’ve come to the right place. Inside, you’ll find the official breakdown of whether or not Mike O’Hearn has ever used gear before…

Mike O’Hearn is a true legend in the fitness industry. He is famous for winning the natural Mr. Olympia competition 4 separate times, starring on the cover of hundreds of fitness magazines, and for starring in the 2008 TV series Gladiator.

Mike O’Hearn has always denied using steroids – but that doesn’t mean he is natty. Mike is either one of the biggest and strongest natural bodybuilders the world has ever seen, or a “fake natty.”

So what’s the verdict – is Mike O’Hearn really a natural bodybuilder? Or did he use anabolic steroids to go beyond his natural limits and take his physique to the next level? Let’s find out!

What Are Steroids?

People are constantly accusing Mike O’Hearn of using steroids, or for being a “fake natty.” But before we talk about Mike’s status as a natural bodybuilder, we have to talk about steroids themselves.

Most anabolic steroids are derivatives of the hormone testosterone.

They mimic the effects of testosterone in the body, which explains why they are so effective at building muscle mass and strength. Steroids are actually illegal in the United States and many developed countries, but that hasn’t stopped millions of men from using them.

Studies show that over 1 in 20 men around the world has used steroids at least once in their lifetime, and the numbers are very similar in the United States [1].

This makes sense, as steroids make it much easier to build muscle mass and lose body fat [2].

Many fitness influencers and Hollywood movie stars have used steroids to transform their physiques in record time.

Unfortunately, steroids also have many dangerous side effects that you need to be aware of. They are especially dangerous to the cardiovascular system, and can even cause death when used improperly [3] [4].

For most people, avoiding steroids altogether is probably the right choice. If you are still interested in steroids, then it’s important to do your research so you can make a well-informed decision.

Signs of Steroid Usage

How can you tell if someone like Mike O’Hearn is using steroids? The easiest way is to look for any obvious side effects of long-term steroid use.

Here are some of the most common signs that someone is on gear:

  • Shoulder / Back Acne
  • Rapid Body Transformation
  • Insanely Large Shoulders / Traps
  • Red / Flushed Skin
  • Completely Shredded Physique

Let’s take a closer look at each of these side effects.

One of the most obvious signs of steroid use is actually acne – especially on the shoulders and back. If you see someone with acne all over these muscle groups, then they are probably abusing anabolic steroids such as testosterone.

Another dead giveaway for steroid use is a rapid body transformation. Many actors and Hollywood movie stars can completely transform their physique in 3-4 months using different performance enhancing drugs.

If you see someone go from “Dad bod” to “God bod” in 12 weeks, then they probably used anabolic steroids.

Other signs of steroid use include insanely large shoulders and traps, red / flushed skin, or a completely shredded physique.

Is Mike O’Hearn On Steroids?

Is Mike O’Hearn natty? Or did he use anabolic steroids to become one of the world’s biggest fitness icons? Let’s look at the facts before jumping to any conclusions.

Mike O’Hearn has the following signs of long-term steroid use:

  • Insanely Muscular Physique
  • Extreme Muscle Density
  • Super Human Strength
  • Completely Shredded
  • Impressive Longevity

Mike O’Hearn has repeatedly claimed “natty” status, but looking at all of these potential signs of steroid use, I’m not so sure.

The biggest sign that Mike O’Hearn might be using steroids is his insanely muscular physique. Mike is 6 feet 3 inches tall and weighs an unbelievable 245 pounds. In other words, Mike O’Hearn is just as big as Arnold Schwarzenegger at the peak of his career!

Is it really possible for someone to be as big as the Austrian Oak without using anabolic steroids?

It’s highly unlikely in my opinion. Mike also has extreme muscle density in many muscle groups, including his chest, back, shoulders, and quadriceps.

Many anabolic steroids such as testosterone and trenbolone are known to help build this dense, powerful look, so this is another potential sign that Mike is on gear.

Of course, Mike O’Hearn isn’t just big – he’s also incredibly strong, and has what I would call “super human strength.” He can easily rep out 400+ pounds for reps on the incline bench press, and he regularly outlifts many of the strongest men in the world, including the world-class powerlifters Stan Efferding and Matt Wenning.

Again, it’s hard to believe that someone could get this strong as a drug-free athlete…

Mike O’Hearn has some other signs of steroid use, such as his completely shredded physique, and his longevity in the iron game. Mike stays completely ripped year-round, something that is almost impossible for a natural athlete to pull off.

He has also maintained his impressive physique well into his 40s – again, this is almost impossible to do without drugs, as men’s testosterone levels start to decline after age 30 or so.

So what doe Mike O’Hearn have to say about these accusations?

The truth is, Mike has always denied using steroids throughout his career. To his credit, Mike has competed in many drug-tested competitions, and even won the natural Mr. Universe competition 4 separate times.

Mike has performed many drug tests throughout his career, and all of them came back negative.

Mike O’Hearn has many signs of long-term steroid use, but he has repeatedly tested negative for anabolic steroids during his bodybuilding career.

I’m going to give Mike O’Hearn the benefit of the doubt and say he is “natural,” but it wouldn’t surprise me if he started using steroids in his 30s or 40s to maintain his impressive physique.

Mike O’Hearn Before And After Steroids

Mike O’Hearn has many of the usual signs of long-term steroid use, such as an insanely muscular physique, super human strength, and extreme muscle density.

But did he always look this way?

The truth is, Mike O’Hearn has always been a pretty big guy. Mike says that he weighed as much as 270 pounds when he was just 16 years old!

This is hard to believe, but I think he’s telling the truth here. Mike O’Hearn has always been a monster of a human being, and his physique really hasn’t changed that much over the years.

It’s hard to believe that someone can get as big or as strong as Mike without using steroids. However, in this case we have to give him the benefit of the doubt – especially when you consider he competed in many drug-tested bodybuilding competitions.

It’s hard to believe it, but Mike O’Hearn is probably natty.

Legal Steroid Alternatives?

Believe it or not, Mike O’Hearn probably built his incredible physique without using anabolic steroids.

This is great news for anyone who wants to build a fitness model physique without using illegal drugs.

If you want to build a Mike O’Hearn style physique, but aren’t interested in using anabolic steroids and other performance enhancing drugs, then “legal steroid alternatives” may be a good choice for you.

Legal steroid alternatives are natural substances that produce steroid-like results, but without any of their dangerous side effects.

If you are looking for a great legal steroid alternative to speed up your gains in the gym, then our #1 recommendation is a natural product called ecdysterone.

Ecdysterone belongs to a family of plant hormones called “ecdysteroids.”

Ecdysterone has a similar chemical structure to testosterone. However, unlike testosterone and other anabolic steroids, ecdysterone does NOT increase your hormone levels. Instead, it directly increasing the rate of muscle protein synthesis in humans.

Studies show that ecdysterone can increase protein synthesis by as much as 20%, which makes it at least as effective as some anabolic steroids [5, 6]. This may sound too good to be true, but the latest research shows that ecdysterone is the real deal.

Here are a few of the benefits that you can expect when using ecdysterone:

  • Increased Muscle Density
  • Faster Fat Loss
  • Increased Strength Gains
  • Enhanced Recovery

Best of all, ecdysterone is perfectly safe, with almost zero side effects.

If you are serious about reaching your fitness goals in record time, then we strongly recommend getting your ecdysterone through Huge Supplements. They manufacture their ecdysterone product right here in the US under FDA-regulated facilities, so you know you are getting the highest quality product for your money.

Testosterone Therapy vs. Steroids

Testosterone replacement therapy is the #1 treatment option in the world for men suffering from low T.

Here’s how it works: if you think you are suffering from low testosterone levels, then your doctor will order a blood test to measure your exact testosterone and estrogen levels.

If the blood test shows you have low T, then your doctor will give you a prescription testosterone medication that you can use to safely raise your testosterone levels.

Here are just a few of the benefits you can expect on a doctor-supervised TRT program [7, 8, 9]:

  • Increased Energy Levels
  • Improved Libido
  • Improved Bone Density
  • Improved Bone Density
  • Stronger Immune System

Don’t worry – testosterone therapy is extremely safe.

Most patients rarely experience symptoms, and when they do, it’s usually something minor like skin irritation. And this can be avoided entirely when you work with a company like Fountain TRT that uses testosterone creams, rather than painful testosterone injections.

If you are ready to get started with testosterone therapy, then we strongly recommend a reliable, patient-focused online TRT provider like Fountain TRT.

Mike O’Hearn and Steroids | Verdict

What’s the verdict – does Mike O’Hearn use steroids?

It’s very difficult to say for sure, but we believe the odds are very high that Mike O’Hearn is natty.

It’s true that Mike O’Hearn has many of the usual signs of long-term steroid use, such as an insanely muscular physique, extreme muscle density, and super human strength.

However, Mike O’Hearn has competed in many drug-free competitions, including the natural Mr. Universe contest, and he has never failed a drug test. Mike O’Hearn was also 275 pounds his senior year in high school, which tells us that he never went through a rapid “growth spurt” during his adult life.

Mike O’Hearn is probably just a genetic freak who was able to build his incredible physique without drugs.

To be fair, we think the odds are very high that Mike is on some type of testosterone replacement therapy program to maintain his physique. After all, Mike is well into his 40s, and men’s testosterone levels start to decline after age 30 or so.

If you are interested in getting started with testosterone therapy, then the online provider Fountain TRT is our #1 recommendation.

If you aren’t ready to get started with testosterone therapy, then a great legal steroid alternative like ecdysterone is another fantastic option.
