What Are Steroids?

Steroids are hormones that occur naturally in the human body. They are important for your cells, organ, and tissues to perform their functions.

Anabolic steroids, or man-made versions of these naturally occurring hormones, are sometimes used by some bodybuilders and other athletes to build muscle mass and enhance their physical performance.

Steroids are technically illegal in the United States and many other countries, but that hasn’t stopped many people from using them.

Approximately 6.4 % of all men have used anabolic steroids before [1]. It is also reported that 2.9–4.0 million Americans may have used anabolic steroids, with possibly one million of these having experienced anabolic steroids dependence [2].

So what makes anabolic steroids so effective? The reason they work is they increase the levels of testosterone and other muscle-building hormones in your body. These hormones bind to your muscles and other tissues and increase different muscle-building pathways [3, 4].

Although steroids have many benefits, they also have serious side effects, which can negatively impact the human body. Steroids can cause adverse effects on your brain, cardiovascular system, muscular system, liver, urinary system, and reproductive system [5].

The bottom line is anabolic steroids are synthetic (man-made) versions of testosterone. They raise the levels of testosterone in the human body. Although they enhance physical performance, they also have many side effects and are banned in most professional sports. Anabolic steroids are also illegal in the US and many other countries.

Signs Of Steroid Use

Is it possible to say if someone is on steroids? The truth is you can never be 100% sure. However, there are some common signs and symptoms that you can look for in a potential steroid user.

Below are some of the most common signs of long-term steroid use:

  • Unusual Muscle Growth
  • Large / Prominent Jawline
  • Red, Flushed Skin
  • “Joe Rogan” Gut
  • Square Shaped Physique

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

One of the most common signs of long-term steroid use is unusual muscle growth. Certain muscle groups, like the shoulders and traps, have a large number of androgen receptors.

Many first-time steroid users find that their shoulders and traps grow way faster than the rest of their body. If you see someone with overpowering shoulders and traps, then that may be a sign of steroid use.

Another dead giveaway of steroid use is a “Joe Rogan” gut. Even when the individual is lean, their stomach sticks out in front of the rest of their body. This is caused by long-term growth hormone and insulin use.

These hormones cause the intestines and other organs to grow in size, which pushes out the stomach, giving the appearance of a distended gut.

There are other signs of steroid use, such as red / flushed skin, a hyper-masculine jawline, or a “square” shaped physique. If someone has some or all of these signs, then the odds are very high that they are using performance enhancing drugs.

Is Jeff Seid On Steroids?

Is Jeff Seid really natural? Or is he using steroids to take his physique to the next level? It’s hard to know for sure, but there is plenty of real-world evidence that Jeff may be using performance enhancing drugs.

Jeff Seid has the following signs of long-term steroid use:

  • Incredibly Muscular Physique
  • Ripped Year-Round
  • Cannon Ball Delts
  • Extremely Strong Jawline

The most obvious sign that Jeff Seid is using anabolic steroids is his incredibly muscular physique. Jeff Seid is 6 feet tall and weighs an incredible 200 pounds. It’s almost impossible for most natural bodybuilders to get this big, bug Jeff Seid makes it look easy.

Another huge giveaway is his ripped body. Jeff Seid is around 6-8% body fat year-round!

Research shows that most natural bodybuilders have a hard time staying this lean for extended periods of time, as their muscle-building hormones like testosterone start to decrease when they get to lean.

Jeff Seid is either on the juice, or an absolute freak of nature, as he can stay shredded year-round while maintaining a ton of muscle mass.

Jeff Seid has many other signs of long-term steroid use, such as his incredibly large shoulders, and his extremely strong jawline. Research shows that the deltoid muscles have a very large number of androgen receptors.

Most steroid users find that their shoulders grow way faster than the rest of their body, as the deltoid muscles are very sensitive to the effects of elevated androgen levels.

Seriously, when was the last time you saw a natural bodybuilder with Jeff Seid’s shoulder development? It’s just not something you see on most people. Jeff Seid also has an incredibly strong jawline, which may be a side effect of elevated testosterone levels.

Jeff Seid has always denied using steroids, and he has never failed a drug test. For example, here is Jeff responding to one of his fans who accused him of being on the sauce:

“No steroids were used in the making of this physique. Stay natural my friends.”

Jeff worked very hard to build his incredible physique, but we don’t believe him when he says he is natural. There are just too many obvious signs that he has dabbled with performance enhancing drugs in the past.

Jeff Seid Before And After Steroids

Jeff Seid has many of the usual signs of long-term steroid use, such as an insanely muscular physique and massive 3-D shoulders. But did he always look this way?

The truth is, Jeff Seid has always been ripped. He had six pack abs when he started lifting – a clear sign of his above average genetic potential. However, that completely changed when he started getting serious about his physique.

Today Jeff Seid is one of the biggest fitness influencers in the world, with extremely wide shoulders and an incredible V-taper.

Is it really possible for someone to transform their physique like this as a “natural” athlete? Technically it’s possible, but we have our doubts. It’s much more likely that Jeff Seid used performance enhancing drugs to transform his physique.

Legal Steroid Alternatives?

Jeff Seid may have used anabolic steroids to build his super-human physique, but that doesn’t mean they are a good idea for everyone. Steroids have many side effects, and can be extremely dangerous when used improperly.

Fortunately, there are legal over-the-counter products that you can use to get faster results in the gym. Some of these products are called “legal steroid alternatives,” because the produce results that are almost as good as many drugs.

One of the most popular legal steroid alternatives on the market today is called Ecdysterone.

Ecdysterone belongs to a family of plant steroids called “ecdysteroids.” Don’t worry – ecdysterone is not an anabolic steroid, and it has no long-term side effects.

Plants produce it because it causes them to rapidly increase in size. And studies have shown that ecdysterone produces incredible results in humans.
In fact, a recent study showed that ecdysterone works better than many anabolic steroids, including dianabol, for building muscle mass and strength [6].

Ecdysterone works by increasing the rate of protein synthesis inside the muscle cells. One study showed that it boosts protein synthesis by as much as 20% [7]! This is absolutely incredible for an over-the-counter product.

Best of all, ecdysterone has zero side effects in humans, especially when taken at the recommended dosage of 500 mg per day. If you are interested in purchasing your own ecdysterone, then we highly recommend the company Huge Supplements.

Testosterone Therapy vs. Steroids

Testosterone replacement therapy is a great way for men with low T to safely raise their testosterone levels.

The goal with testosterone therapy is to raise your total testosterone levels to the high-end of the normal, healthy range [8]. This is completely different from something like anabolic steroids, where the goal is to raise your testosterone levels to unhealthy levels to maximize athletic performance.

Most users on TRT report improved energy levels, increased muscle mass, decreased body fat, improved sexual performance, and an improved overall quality of life [9, 10, 11].

If you are interested in getting started with testosterone therapy, then we strongly recommend a good online TRT provider, such as Fountain TRT.

This company was founded by a board-certified urologist with decades of experience helping men with low T. Best of all, you can talk to your doctor, and get your prescription testosterone medication, without ever setting foot in a doctor’s office.
