What Are Steroids?

Anabolic steroids are one of the most controversial topics in the fitness industry.

In reality, steroids are nothing more than man-made versions of the chemical testosterone. Steroids work by increasing the user’s testosterone levels to supra-physiological levels, or levels beyond what the user can produce naturally.

Steroids are illegal in most countries and considered a “banned substance” in most professional sports, such as the Olympic Games. However, that hasn’t stopped men all over the world from using them.

It’s estimated that over 1 million men in the United States has experimented with anabolic steroids, and the numbers are even higher in many other countries [1].

So what makes steroids so attractive?

Studies show that steroids are incredibly effective at building muscle mass and improving overall athletic performance [2]. Even some cyclists such as Lance Armstrong have been caught using steroids, as research shows they also greatly benefit the user’s cardiovascular endurance [3] [4].

Unfortunately, steroids also have many dangerous side effects. Some bodybuilders have actually died following long-term steroid use, while others have suffered permanent damage to their liver, kidneys, and heart.

Steroids are very dangerous, and illegal in most developed countries, so you should think twice before using them.

Testosterone replacement therapy is another viable option for men who want to safely optimize their hormone levels.

Signs of Steroid Usage

The truth is you can usually figure out if someone is using gear just by looking for some common signs and symptoms. If they have them, then the odds are reasonably high that they are “juicing.”

Here are some of the most common side effects of long-term steroid use:

  • Superhuman Strength
  • Insanely Bloated Stomach
  • Extreme Vascularity
  • Rapid Body Transformation
  • Insanely Muscular Physique

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

One of the biggest signs of steroid use is superhuman strength. Many bodybuilders, powerlifters and strongman competitors are so strong that it’s hard to believe. We’re talking about people deadlifting over 800 pounds and incline pressing the 200 pound dumbbells for reps!

It’s almost impossible for someone to get this strong as a natural athlete, so this is a clear sign that someone is on gear.

Another common side effect of steroid use is an insanely bloated stomach. Some drugs like growth hormone and insulin actually push out the stomach.

Many professional bodybuilders actually look pregnant, even when they are lean with six-pack abs! If you see someone who is lean with an insanely bloated stomach, then they are probably on gear.

Other signs of steroids include extreme vascularity, rapid body transformations, and an insanely muscular physique

Is Jason Giambi On Steroids?

Is Jason Giambi natty? Or did he use anabolic steroids to get an unfair advantage over his competition? Let’s look at the facts before jumping to any conclusions.

The truth is Jason Giambi doesn’t have any obvious signs of long-term steroid use.

He doesn’t have an insanely muscular physique, massive 3-D shoulders, or even ripped six-pack abs. He just looks like an out-of-shape athlete who spent too much time at Krispy Kreeme Doughnuts in the offseason!

However, that doesn’t mean Jason Giambi is a “natural” athlete. There is still plenty of evidence that he used anabolic steroids during his professional baseball career.

Jason was a professional baseball player for the Oakland Athletics, New York Yankees, Colorado Rockies, and the Cleveland Indians. Giambi has won various Major League Baseball awards like being the MVP in 2000, winning the All-Star award five times, and winning the Silver Slugger award twice.

Safe to say that Jason was exceptionally good at what he did. But did he use any Performance Enhancers?

The answer is a very straightforward “yes.”

Jason admitted to using both testosterone and growth hormone in 2003. In the testimony of the BALCO steroids, Jason admitted to using these substances during the 2003 season, which would have given him a massive advantage in the game.

So why did Jason decide to “take the plunge” and start using gear?

To be honest, his embarrassing performance in the 2003 season of Major League Baseball probably had something to do with it… During the 2003 season, his batting average dropped to a mediocre .250, and he led the league in strikeouts. Not good!

Secondly, because this was the “steroid era” of professional baseball, most of the athletes weren’t being tested for performance enhancing drugs. This means there was no chance of Jason being caught.

Unfortunately, 2004 was still not a great year for Jason. His career only saw a high again in 2005, when he was named the AL Comeback Player of the Year.

The bottom line is Jason Giambi used anabolic steroids to get an unfair advantage over other professional baseball players.

He tested positive for steroids, and he eventually admitted to using them starting in 2003. Jason is proof that you can use anabolic steroids, and still look like a cop who is investigating the drive through menu at your local Dunkin Doughnuts.

At the very least, steroids are not a magic drug that will automatically take you from “Dad bod” to “God bod.” You still need a smart diet and training program to see great results.

Jason Giambi Before And After Steroids

Jason Giambi doesn’t have any of the usual signs of long-term steroid use, such as an insanely muscular physique, a growth hormone gut, or red / flushed skin.

Okay, Jason does have a an extra “spare tire” on his stomach – but that was probably caused by him stuffing his face full of Krispy Kreme doughnuts in the offseason, rather than growth hormone abuse.

Jason Giambi pretty much looked the same from the start of his professional baseball career, to the end. His physique never really changed, and he never achieved that ultra-muscular look that you would expect from most steroid users.

Jason Giambi is proof that you can use anabolic steroids and still look like an out-of-shape athlete if you don’t train hard in the gym and follow a smart diet.

Legal Steroid Alternatives?

Anabolic steroids are probably not a great idea for most men. They are very effective for building muscle mass and strength, but they can also be extremely dangerous.

Many long-term steroid users have long-term damage to their internal organs, such as their heart, liver, and kidneys.

Besides, it’s not like steroids are a guaranteed way to get jacked. Jason Giambi probably took steroids during his baseball career, and he looks more like a couch potato than an athlete!

If you want to safely speed up your progress in the gym, then we strongly recommend a research-based “legal steroid alternative” like ecdysterone, rather than traditional anabolic steroids.

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

Insects produce ecdysterone because it boosts protein synthesis and dramatically increases their growth and development. However, newer research shows that ecdysterone works just as well in humans as it does in insects!

So how effective is ecdysterone?

Studies show that ecdysterone is as effective as dianabol and other anabolic steroids for building muscle mass and strength! This is possible because ecdysterone increases muscle protein synthesis in humans by up to 20% [5, 6].

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

  • Increased Muscle Mass
  • Reduced Body Fat Levels
  • Increased Muscle Strength
  • Faster Recovery

Don’t worry – ecdysterone doesn’t have any dangerous side effects. In fact, research shows that it is perfectly safe when taken at the recommended dose of 500 mg per day.

There are a lot of great online companies selling ecdysterone, but our #1 recommendation goes to Huge Supplements. They have more 5-star reviews than almost any other company, which tells us a lot about the quality of their products.

Testosterone Therapy vs. Steroids

Testosterone replacement therapy is one of the most important medical interventions for men in the 21st century.

Millions of men are suffering from signs and symptoms of low T, and while there are natural solutions that can help, testosterone therapy is considered the most effective strategy for optimizing your hormone levels.

The basic goal of testosterone therapy is to raise your total testosterone levels to that of a healthy 18 year-old male.

Don’t worry – testosterone therapy is perfectly safe, and completely different from something like anabolic steroids.

Here are a few of the benefits to a doctor-supervised TRT program [7, 8, 9]:

  • Decreased Body Fat Levels
  • Increased Muscle Mass
  • Improved Mental Focus
  • Improved Muscular Endurance
  • Increased Energy Levels

If you think you have symptoms of low T, then you have to talk to one of the online TRT doctors at Fountain TRT. All you have to do is complete their online survey, and one of their experienced TRT doctors will reach out to you to discuss your symptoms of low T.

Jason Giambi and Steroids | Verdict

What’s the verdict – does Jason Giambi use steroids?

We believe the odds are extremely high that Jason Giambi used anabolic steroids during his professional baseball career to gain an unfair advantage over his competition.

Jason Giambi doesn’t have any of the usual signs of long-term steroid use, such as an insanely muscular physique, super human strength, or extreme muscle density. In fact, Jason barely looks like an athlete!

I thought it was impossible to use steroids and still look like Dunkin Doughnuts’ “most valuable customer,” but he proved me wrong.

Jason Giambi tested positive for banned substances during his baseball career, so we are extremely confident that he used anabolic steroids. Jason Giambi may have used anabolic steroids, but they probably aren’t a good choice for everyone. After all, steroids can be extremely dangerous, and have many negative side effects.

If you are interested in optimizing your hormone levels, then a doctor-supervised TRT program is probably a better choice.

We really like the online company Fountain TRT, as they make it as easy as possible for you to get started.

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