Deca – Pros, Cons and Everything In Between

Deca Durabolin used to be one of the most popular anabolic steroids out there back when steroids were all the rage in the world of bodybuilding. Nowadays, it is illegal to use in the United States without a prescription, while it still remains one of the go-to steroids around the world – so, should you use it?

Deca Durabolin (popularized as “Deca”) is a steroid that is made out of Nandrolone. Clinically, Nandrolone esters are most commonly used for treatments of people who suffer from diseases or syndromes that can cause catabolic states. Most commonly, they use it for cancer or AIDS, however, it is also being used less and less as the time goes on. However, it is not the use that made Deca this popular. It was the fact that a lot of athletes and bodybuilders chose to use Nandrolone esters to boost their performance or their physique.

So, what are the pros and cons of Deca?

Now, we know that anabolic steroids will provide certain benefits to anyone who chooses to use them over deciding to be a natty. But, the fact that you are taking a shortcut to bigger muscles, less fat in your body and not to mention the extra energy, can probably tip you off that there is a downside to using Deca as well. As we know, any steroid out there right now comes with potentially severe negative effects, so, we should probably list them out for you to be able to make an informed choice.


Now, there is a reason Nandrolone (still Deca, just a different name) is as popular as it is. It has already shown that it can be extremely effective for some people. Especially so if their body reacts to it perfectly. So, what are the benefits it provides to the user?

  1. You will eat more. While someone looking to cut will not be overly excited about the prospect of their appetite being overly stimulated, if they are trying to bulk up they will love how easy it will be to get those calories up. Remember, diet is still the most important factor in body building, and if you do not ingest enough of a caloric excess, you will not gain mass.
  2. Your blood cell production will be increased. Red blood cells are incredibly important, as you can guess, but most people do not know why. They carry hemoglobin, which, in turn, carries oxygen to where it needs to go. They will also take carbon dioxide from your blood and transport it to your lungs so that you can exhale it. All of this means that your workouts will become increasingly more satisfying and you will not be losing your breath or strength as quickly as you did without Deca.
  3. Your bones will have a higher density. Deca Durabolin also increases bone density. And, while this effect is incredibly useful in medical treatments of osteoporosis, it is also held in high regard by body builders. The fact that Nandrolone will increase the amount of minerals in your bones and strengthen them also means that it will allow you to lift heavier weights safely.
  4. The favorite one – more muscle mass. This is the reason people even start using Deca. With a smart plan and enough training, Deca will help you increase your muscle mass significantly. In fact, a study from 2005 has found that 2 years of using Deca even without any serious training can increase your lean mass for over 12%. You can only imagine how effective it is when you actually take your workouts seriously.
  5. Its side effects are a bit lessened compared to most other steroids. While it is not entirely safe, Deca is considered to be one of the safer anabolic steroids out there. It does not break down like other steroids and does not exhibit the same levels of liver toxicity. And, as you probably know, it does convert to estrogen, (which is not a good thing, mind you) but it does it at a slower rate than other choices. And thus, once more, it is a bit safer.

As you can see, the benefits are numerous, Nandrolone will provide a lot of help to anyone who is trying to reach their goals when it comes to serious bodybuilding. It will make you feel better while you work out. It will shorten the recovery period. It will help you maintain your calories and gain mass. So, are there downsides to it?


We have gone through the benefits of Deca, but using anabolic steroids does come at a risk, and some of the side effects that come with someone using Deca are quite frightening.  In fact, you can easily google the side-effects and see them on Web MD, we will just mention the more common ones.

  1. Mental effects. Using Nandrolone comes with a risk for your mental health. It has been linked to depression, insomnia, numbed or heightened emotional reactions, irritability and more.
  2. Liver problems. Sure, we mentioned that Deca is less toxic for your liver than most other steroids, but it is still toxic. If you have a pre-existing condition regarding your liver, you would be wise to avoid using Deca altogether.
  3. Bleeding risks. Those who use Deca are commonly faced with increased risk of bleeding. They bruise easily and can have other issues, such as unexpected nose bleeds. While it does not sound horrible, if you ever need to have surgery, it might be riskier than if you are a Deca user.
  4. Swelling. While water retention that causes swelling is not all too bad of a side effect, you need to understand that an edema can cause very dangerous symptoms. In fact, if you’re particularly unlucky, a single edema has the potential to be lethal.
  5. Acne. Deca can cause skin thickening and lead to serious acne problems to those who use it. And the problems can persist for over a year after quitting Deca.

And there are more serious potential side effects that come with people using larger doses and staying on Deca for longer periods of time. These include:

  1. Reduced libido and erectile dysfunction.
  2. Potential cardiovascular damage
  3. Serious liver issues.

Is it worth it?

Well, this is a highly subjective question to ask, what is worth for some is definitely not worth for others. If you are confident about your knowledge and experience, and you are not from the US, you can try it out. But, if like myself, you are from the United States, you should know that Deca is only legal to use with a prescription. And getting a thousand dollar fine might not be worth it in the end. So, why not try using some of the available alternatives?

Safe alternatives

Deca was first used in the early sixties, and, while it did provide great results, you should understand that, in this day and age, we have found better ways to get those results. There are legal and safe alternatives to Deca Durabolin that are a lot easier to come by. One of them is Decaduro, a legal steroid sold by Crazy Bulk. It offers almost all of the benefits while being devoid of side effects that Deca usually causes.

In essence, they have traded the sheer effectiveness of Deca as it was and toned it down a bit to make a perfectly safe version. Of course, you would still be wise to go through the list of ingredients and make sure you are not allergic to any of them and consult your doctor to see if it might clash with any of the meds you may currently be taking.

So, in the end, a choice to go with a legal alternative that offers a safe way to reach the same results seems to be a much smarter choice for anyone who wants to take their health seriously.
