What’s up fellow gym bros?

Thanks for stopping by.

In today’s article, we’re talking about steroids.

Who knew, right?

Specifically, we’re talking about two of the biggest boys in town.

We’re talking about Deca, and we’re talking about Tren.

Specifically, we’re looking at Deca vs Tren.

Over the decades, the sport of bodybuilding has grown and evolved at an astonishing rate.

We know that guys like Eugene Sandow gave birth to our beautiful sport.

And we know that greats like Lee Haney and Arnold Schwarzenegger helped to shape it into what it is today.

Back then, it was all about the aesthetics and the hard work that the bodybuilders put in inside the gym.

Nowadays it’s very much supplement orientated, which is kind of ironic when you think about it.

Supplements do play a huge role in determining how big and jacked a person can get.

But to build an Olympia-grade physique through creatine and whey protein alone?

Come on, nobody’s buying that, surely?

Well actually, plenty of people are buying that, which is why the supplement industry is raking in billions every single year.

Those that are truly in the know however, know that a 5-foot 10-inch man does not naturally weigh around 270 – 280 pounds of solid muscle.

They know that to get to the size of the dudes on stage at the Olympia.

You need to be taking some pretty strong gear.

That brings us to Deca vs Tren.

Legal Disclaimer:

We do not condone nor recommend the use of steroids.

Steroids are very dangerous and if misused or abused, they can potentially be fatal.

With that said, we understand that people choose to knowingly use them, despite being aware of the risks.

That’s why we have compiled this article and created this website.

Deca Durabolin

To inform our readers about the risks of steroids, and to look at how to use them as safely as possible.

Deca Durabolin:

Back in the 1980s and early 1990s, there was one steroid that ruled them all.

This fabled steroid was the stuff of legend in gym locker rooms up and down the country.

Gym bros would slink into the locker room after a lifting session, gaze upon their scrawny physique in the mirror.

And a year for a compound that packed muscle mass on while keeping them lean and helping their lifts increase in the process.

Their prayers were answered when word got about a steroid known as Deca Durabolin, for short.

For bodybuilders that were in the off-season and looking to beef up and pack on the muscle.

Deca was very much the steroid of choice.

Word spread about how effective it was, and soon, more steroid users than ever before were using Deca and they were seeing some very impressive results because of this.

Because it became so popular, bro-science quickly took over.

And Deca was viewed almost like a mythical creation of the Gods themselves.

People were quick to sing the praises of Deca, and somewhere along the way.

Some cretin decided to spread the rumor that Deca provided incredible gains in muscle mass, size, and strength, without a single negative side effect.

Sadly, people believed this hype and, let’s just say, there were sadly some lives lost.

And far too many men walking around with gyno, (man boobs) acne, hypertension, Palumboism, suppressed testosterone production, and much more besides.

Deca is milder than some steroids out there, but it certainly isn’t creatine.

Deca Vs Tren

What Is Deca?

Deca is an anabolic steroid that is used by bodybuilders in the off-season.

Who is looking to build muscle and bulk up?

It holds some similarities to Trenbolone, which is why we’re looking at differences today.

One similarity is the fact that it, like Tren, is lacking a carbon atom at the 19th position.

It also aromatizes at 1/4th the rate of what testosterone does.

Because it aromatizes slower than testosterone, this is why it is considered to be a fairly-mild steroid and no doubt.

It’s why some bro-scientists out there decided to flap their gums and run their mouths about how Deca was completely safe.

These same dudes were probably selling the stuff out of the trunks of their cars in the gym carpark.

So they would likely want to make out that Deca was completely safe, when in fact it wasn’t.

Like most other steroids, this drug wasn’t initially created to help lifters get jacked out of their minds.

It was produced in the 1960s by a company named ‘Organon’ and was designed for women.

Yep, it was created to help treat osteoporosis in women going through the Menopause.

These women being treated with the steroid however, soon noticed how they were gaining weight and becoming stronger.

Soon, the performance-enhancing benefits of Deca were looked into.

And athletes began using the steroid and seeing very impressive results.

A female athlete named Marion Jones was found to have used the drug, and after admitting to taking it.

She was subsequently cast into the eternal pits of hell, never to be seen again.

Okay, that’s a slight over-exaggeration, but she was stripped of her medals and publicly, shamed and disgraced by the media.

If a world-class athlete could use the drug and benefit from it.

What could it do for your typical gym rat looking to get jacked for summertime and beach season?

More and more lifters began experimenting with Deca, and the rest, as they say, is history.

Deca Pros

Now that we’ve enlightened you as to what Deca is.

We’ll now look at exactly what it is that makes this drug so popular amongst bodybuilders in the off-season.

A few benefits of using Deca include the following:

Great For Bulking

First and foremost, Deca is a drug that is used by bodybuilders bulking up in the off-season.

It is not a steroid for cutting, so if you want to get ripped, please stick to your winstrol and Clen.

Deca is very effective when it comes to building and retaining muscle mass, plus it also increases your strength.

Being strong is actually an important part of any bulking plan because the stronger you are, the more weight you can lift.

The more weight you can lift, the more pressure you can put on your muscles, and the harder you can work them.

Deca helps the muscles, or rather, the cells in your muscles, to retain more nitrogen.

Nitrogen is vital for protein synthesis, which is a natural process responsible for the production of new muscle protein tissues.

The more nitrogen you retain, the greater the rates of protein synthesis, and the greater the amounts of muscle you can build.

Yes, Deca does indeed cause a little bloating, but if you want to bulk up, it’s a great choice.

Increased Red Blood Cell Counts

Another great advantage of this steroid is that it helps to increase the amounts of red blood cells that your body can produce.

This is very important because red blood cells transport oxygen and nutrients around your body.

And deliver them to other cells, which are then used for energy.

The more oxygen and nutrients these cells can absorb, the more energy they can produce.

For athletic purposes, this is very important, and it is why athletes often train at high altitudes.

Great For The Joints

Now, the bigger and more muscular you are, the heavier you become.

This is not good for the joints.

This is why some steroids are very bad for the joints.

Deca however, is an exception.

Yes, it bulks you up, but it also speeds up the production of collagen.

Collagen helps to protect the joints and tendons.


This not only protects them, but it also helps to improve flexibility and mobility, which again, is great for athletic purposes.


Now it’s time for us to take a look at Tren.

Tren is the big daddy of all steroids.

Do you know those enormous bodybuilders that look like mutants and genetic freaks?

Well, they didn’t get that big by chugging down whey protein and creating a couple of times per day.

They got to the size they were because of the fact that they were almost certainly using Tren.

Tren is seriously strong, and it should only be used by experienced bodybuilders and steroid users that know exactly what they’re doing.

Tren is considered to be the most powerful steroid in the history of steroids.

And if you’re looking to bulk up and pack on some serious muscle mass this off-season.

Adding Tren to your stack is a great way to go about it.

When it comes down to which is the strongest, Tren is, by far, the more powerful of the two.

While Deca provides some nasty side effects, those provided by Tren are pretty awful if we’re being honest.

A Tren cycle has the potential to pack as much as 40 pounds of muscle onto your frame in a matter of months.

It increases nitrogen uptake levels, it boosts protein synthesis.

It builds muscle like there’s no tomorrow, and it even helps to keep you looking lean when you’re bulking.

What is Tren?

Known by many as the ‘King of Steroids’ Tren is a compound that only very serious lifters should consider using.

It is an AAS or Androgenic Anabolic Steroid that was created by a German pharmaceutical company for veterinary uses.

Yes, like many other steroids, it wasn’t actually created for human use at all.

But rather, for use on animals, and we’re talking big animals.

With that said, however, the years went by and soon after, another company picked it up and developed it for humans.

It was designed to help treat and prevent muscle wasting diseases.

It soon became quickly apparent, however, that it was too strong for use on humans, and by the 1990s it was discontinued.

Despite this, bodybuilders had quickly discovered how freakishly big this steroid could help them grow.

So you better believe it became readily available on the black market.

We mentioned earlier how it is lacking a carbon bond in the 19th position.

What truly makes it stand out, however, is the fact that it has a carbon bond located at the 11th position, and at the 9th position.

Because of this change in molecular structure, it is ten times more androgenic and anabolic than Deca.

So, when it comes to the best one, in terms of how powerful it is.

Tren most certainly wins there, but that doesn’t necessarily make it superior.

Tren Pros

Here’s a look at some of the key reasons why Trenbolone is considered the most powerful steroid in the world.

Increased Muscle Mass

When we say it builds muscle, we really mean it.

Tren has the potential to pack muscle mass onto your frame like there’s no tomorrow.

It increases IGF-1, which is an insulin-like growth factor.

Which is incredibly anabolic and therefore helps to promote increases in muscle growth and recovery.

Not only that, but it also improves nitrogen retention.

This means that you retain more nitrogen and that your body can carry out more protein synthesis.

The more protein synthesis your body performs, the more muscle you will build.

Increased Recovery

Another benefit of using Tren is the fact that your muscles will recover quicker after training.

This is vital because we build muscle, not when we train, but when we rest.

The greater your rates of recovery, the greater the amounts of muscle you will likely build.

Plus, it also means that you get to hit the gym quicker, and subsequently, your sessions will improve.

Less Cortisol

Cortisol is a stress hormone produced by the body in times of stress, that naturally suppresses testosterone production.

Studies have found that Tren actually helps to reduce cortisol in the body.

Meaning that you produce less and that your testosterone levels aren’t negatively affected.

Deca Vs Tren: When And Why To Use Each?

In truth, we can’t answer that because it depends on what you want.

Tren is stronger and so side effects are more severe.

Despite this, Deca is still dangerous so Post Cycle Therapy, or PCT, should always be run after using either of the drugs.

In terms of which is best, it really comes down to what you’re looking to get from your training.
