Deca Durabolin Guide: (Side Effects, Cycle, Benefits, Results)

Deca Durabolin Ultimate Guide : (Side Effects, Cycle, Benefits, Results)

If bulking up is your bag, then chances are you’ve come across deca durabolin.

Touted as a milder steroid that still packs a punch, it stands to reason bodybuilders rank it as one of the go-to roids.

This got me thinking:

“What’s so god damn special about this steroid?”

However, no matter how “awesome” deca appears to be we shouldn’t forget drawbacks are always waiting in the wings.

And this is why I’ve done my homework. I’ve dug up the good, bad and downright ugly all for your benefit in this ultimate deca durabolin guide.

Most guys are now using legal deca alternatives, as they mimic the muscle building results without the side effects. More on that later in the article.

Deca Durabolin: What is It?

Deca durabolin is the brand name of the active substance nandrolone decanoate.

It’s an anabolic androgenic steroid (AAS) made up of the hormone nandrolone and an ester of deconoate.

Here’s a chemistry fact for you.

Deca is part of the 19-nortestosterone class of steroids. It’s very much like testosterone apart from there is a change at the 19th atom.

You might be wondering what’s the big deal?

This small change makes a big difference.

The end result gives deca more of an anabolic stature than its competitors.


It’s extremely popular with guys looking to big up the bulk.

It gets better.

It can also hold its own as a therapeutic treatment for various conditions in the medical world.

This all depends on what country you live in.

In the US, deca durabolin is on the list of controlled substances.

Bottom line.

You can only get hold of it with a prescription for medical reasons.

On the other hand.

If you hop on over the border to Mexico you are likely to get it over the counter.

But before you even think about it.

Illegal importation of drugs will lead to heavy prison sentences if you get caught, so don’t even go there.

If competing is your thing, you won’t want to touch deca either.

Here’s the kicker.

It’s on the banned list for all major sporting bodies.

Which is why most guys are now using the legal deca alternative. You can see how it works here.

What Is Deca Durabolin Used for?

deca durabolin

You might be wondering.

“What is deca durabolin good for?”

It’s not just a popular performance steroid you know, it does actually have some proven medical benefits.

Here are a few legitimate uses deca durabolin puts claim to:

#1 Osteoporosis

Deca is known for favourable attributes when it comes to bone tissue density. This is why it’s been used as an effective treatment for osteoporosis. 1 2

#2 Muscle Wasting Diseases

The prevention of muscle wasting is another positive use for deca durabolin. Many studies have found it a good defence against catabolic diseases. 3

And that’s not all.

#3 Anemia

Deca’s red blood cell boosting abilities is also put to good use as alternative for treating anemia. 4

So when someone asks you “What is the steroid deca used to treat?” you can now look like a smart ass and give them the low down.

How Is Deca Durabolin used?

Many will tell you, their first choice of use for deca durabolin would have to be by injection.


Simply because most say the pill versions don’t cut it – it takes too long to hit the system.

Bottom line.

This means you better get used to deeply stabbing needles into large muscles like in your legs, butts or arms to get your fix.

Psst, can I let you into a little secret?

If the thought of needles doesn’t float your boat, there is another option.

The legal alternative to deca is available in an oral form and it will give you the same results.

Why not give that a try?

I tried and tested the #1 legal deca. Here’s what happened.

How Does Deca Durabolin Work?

Deca has a high anabolic rating. In fact, it pips testosterone in the rankings. Yet when it comes to androgenic capacity it’s considerably lower than the male hormone.

You might be wondering why?

The lack of androgenic effects is all down to the way deca works. It converts to DHN (dihydronandrolone) instead of DHT (dihydrotestosterone) in the system.

This is why many say it’s the milder choice compared to testosterone.

I’m not finished.

Deca durabolin also works by increasing protein synthesis, which we all know is vital for muscle gains.

It gets better.

Another classic way deca works is by encouraging nitrogen to store in the muscles. Increased nitrogen retention is also a major player in the muscle growth department. 5

IGF-1 is an insulin-like growth factor hormone is a hormone which funny enough has similar traits to insulin.

Here’s the deal.

The theory goes along the lines – the more of this baby you have in your body the greater chance you have of building muscle mass.

Guess what.

Deca durabolin works to increase the IGF-1 levels in the body.

As you can see, deca works in some significant muscle building enhancements into your workouts.

How Long Does It take for deca durabolin to kick in and how long does it work?

deca durabolin

One thing is certain.

Deca durabolin won’t hit your system fast and hard. In fact it’s totally opposite – this is one very slow releasing steroid.


The pace is controlled by the deconoate ester attached, and it’s this combo which basically slows it down to a snail’s pace.

Here’s the deal.

You will need to have some patience if you are taking this guy.

And that’s not all.

Deca has an incredibly long half life – 15 days. This means once in your system, it works for quite a while, I’m talking anything up to 3 weeks.

This results in one good thing – less frequent top ups.

Bottom line.

As it’s a “slowy”, it will take a while to kick in which means results may seem disappointing at first.

“How long does it really take to kick in?”

In short, you can expect to wait at least 3 to 4 weeks before you start to notice any real improvements.

Remember one thing.

Deca durabolin is a steady steroid, which requires self-control and time before it joins the party.

This also means deca tends to outstay its welcome – expect deca to hang around in your system for up to 18 months.

Deca Durabolin Benefits

Let’s get one thing straight.

You know that personally I’m not one for illegal steroids and this is by no means a pro deca durabolin guide. Having got that out of the way, I do feel it’s only fair to give you guys a true representation of the facts.

Which are?

Quite frankly it’s not one of the most popular roids for no particular reason. Here are the top benefits deca durabolin brings onboard:

  • Impressive gains in muscle mass – deca durabolin will not only give you some rapid increase in size, what gains you see will be lean muscle.
  • Improved recovery times – this is an important one, which means you can go harder sooner after each workout.
  • Easy on the liver – with deca you can forget about any toxic effects on the liver.
  • Milder on the side effects – the slower release of hormones means deca is lighter on the sides.
  • Increases appetite – deca will generate hunger to help you pile on the calories. It’s up to you to make sure they are the right ones.
  • Increased bone density – stronger bones means a stronger frame.
  • Less frequent deca durabolin injections required – let’s face it, who really likes stabbing juice into their butt every day?
  • Improves endurance – the increased production of red blood cells is going to let you bang through those extra reps.
  • Strength gains – as you get bigger and workout more naturally you will grow stronger too.
  • Improves overall performance – when you put all these benefits into one mix, it’s obvious you will see gains all round.
  • Eases pain in the joints – it’s pretty safe to say, anyone who lifts weights will have picked up the odd injury from overtraining along the way.

It gets better.

Some say that deca has anti-inflammatory abilities which help to disguise niggling injuries or pain.

Deca Durabolin Cycle and Injections

deca durabolin

A common question raised in forums time and time again is:

“How much deca should I take?”

I totally get why it’s often asked, after all it’s a valid point.

For obvious reasons deca is most commonly used as part of a bulking phase.

Getting the doses right, is often a tricky decision to make because everyone reacts differently.

Here’s the deal.

Beginners to deca should start in the region of 200 to 400mg per week for a max duration of between 12 to 14 weeks.

Whereas experienced bros typically take a higher dosage – between 600 to 800mg’s but for a shorter period of time.

“What’s the best way to stack deca?”

Despite what some might tell you, deca is a versatile steroid which works well stacked with others. In fact one of the most established stacks is a dianabol, deca and testosterone combo.

Having said that, it doesn’t need to get complicated, mixing deca and testosterone will do just fine for most.

“How often do I need to juice deca?”

In keeping with the simplistic approach, deca only really needs to be injected once a week at most. Although some prefer to split the dose into two smaller shots – either way, it’s what works for you.

Just one more point to take home.

One thing that’s just as important as your actual cycle is making sure you have covered the proper steps when you reach the end of it.

Make sure you have a rock solid PCT in place (post cycle therapy plan) or if you’re lazy just add this PCT supplement at the end of your cycle and it will take care of everything for you.

Deca Durabolin Before After Results

The million dollar question:

“What can I expect from typical deca durabolin gains?”

This kind of question opens a whole can of worms.


There are so many factors which can influence your gains.

Such as?

  • How much effort you put in during training sessions
  • How much deca you are juicing
  • What you are stacking deca with
  • Diet

Taking all this into account you could expect to gain anything from 15lbs upwards during your cycle.

But one thing I will say is your muscles will appear thicker or fuller with deca than other roids of similar status.

We go more deeper into this topic in our Deca Durabolin results article.

Deca Durabolin Side Effects

deca durabolin

You might be wondering.

“Is deca durabolin safe?”

Deca is known for its milder “sides”, across both androgenic and estrogenic points. This is one reason why it’s so popular.


Deca durabolin has a lower aromatization rate and it’s not so androgenic either. This means for many, the side effects are tolerated better on deca than on other steroids in the same class.

To give you a better idea, let’s compare testosterone and deca side by side.

Testosterone has an androgenic rating of 100 where as deca only stands at 37.

Now you can see where I’m coming from.


It goes without saying this doesn’t mean you have a get out of jail free card and that you won’t experience any of the potential drawbacks.

At the end of the day, if you start packing in the high level doses, you will experience the “dark side” of deca durabolin.

Talking of the “dark side” – guys, you might want to take note of this.

One side effect that will occur on deca is going to be a drop in natural testosterone production. It’s one of the traits of anabolic steroids but particularly in this one.

This has a knock on effect with libido and erectile dysfunction to such an extent it’s got its own nickname.

Can you guess what it is?

“Deca dick”

There is minimal risk of estrogenic side effects on lower doses of deca durabolin, but it is a progestin which can bring on similar traits:

  • Water retention
  • Gynecomastia
  • Increase in blood pressure

As for androgenic side effects, because of that low rating you’ve got a slight chance on limited doses. They include things like:

  • Acne
  • Baldness
  • Excess body hair growth
  • Oily skin
  • Mood swings
  • Low sperm count

Women, will experience masculinisation or virulization when taking deca, and that’s why iron maidens are best to avoid.

Side effects include:

  • Deepening of voice
  • Excess body and facial hair growth
  • Enlarged clitoris
  • Increased sex drive

It goes without saying, deca messes with your good and bad cholesterol levels too. This means if you already have issues in this area you might want to side step deca.

    Thanks for the info. First things first, I’m 60 and in pretty good shape (I’m told) however I’d like to be just a bit bigger. I’ve been doing some boxing and recently started to hook back into some weights.
    Diet is pretty good and I train at least 3 times a week.
    I’ve been offered some deca but it seems doing that alone is a no no.
    Any advice is appreciated.

    Hi I am 61 years old, I recently started deca mixed with my test, I feel great my blood pressure did increase quite a bit so my doctor increased my meds starting to fix that problem, my biggest problem is my gut, I’ve been doing crunches every day for years yet my gut is still there you can differentially see my abs but not what I want after 500 crunches a day what do you think is my problem, hell I’m strong my max bench is 325!!

      Hey Fidel,

      You do not need (and should not use) illegal drugs in order to get abs.

      You need to lose body fat in order to reveal your abs. It doesn’t matter how many crunches you do if there’s fat covering your ab muscles.

      Fidel Rosales,

      Abs are made in the kitchen, not in the gym, you have to plan your meals, NOT diet, not even need to count calories, just eat clean and you will see the difference, i went from 96kg to 80kg like in 3-4months without supplements, drugs i barrely did crunches and cardio, i just ate clean, did 3-4 times work out a week.

      Hey Chris,

      Decaduro is a legal and natural supplement that we recommend as an alternative to the steroid. It’s not our product, it’s just what I’ve come across as the best alternative available at the moment :). You can certainly take it with Testo Max.

      You would take them for 30 days or until achieved desired results.
