6 Deca Durabolin Side Effects That You’ll Want To Avoid

Deca-Durabolin Side Effects

Deca Durabolin or just Deca, as it is more popular by that name, is a steroid used by bodybuilders for bulking up. It is one of the most commonly used steroids that not only increase lean muscle mass but also boost strength and endurance.

It is an anabolic steroid that increases testosterone levels and is also called Nandrolone sometimes as it has Nandrolone as the main ingredient. While many argue that Deca has little or no side-effects at all, the truth is like all other steroids it is not innocuous.

It is interesting to know that this drug is also used for some medical conditions like anemia, breast cancer, and osteoporosis. However, the dosages in these cases are so small, hardly any side-effect occurs.

Bodybuilders assume that taking this drug in large quantities will do no harm but that is far from the truth.

 6 Side Effects Of Deca Durabolin


If you have been reading about anabolic steroids or have used them yourself, acne would be no stranger to you. It is one of the most common side-effects of these steroids especially Deca. In some cases, the acne can be very severe so much that it may start popping by itself.

This would be a worrisome problem for anyone who loves and takes care of their skin and face. Even if the acne goes away, the marks it leaves behind may not go away so easily. You will have to regularly see a dermatologist.

Gastrointestinal Issues

Did you know that Deca is a derivative of Nandrolone that is known for causing some serious stomach issues? You could have pretty bad stomach aches or vomit. And if you are eating more to gain muscle, vomiting will definitely impact results.

And if you are not vomiting your food out, your diet may be affected by diarrhoea which is also a possibility in this case.

Low Sperm Count or Impotency

The genitourinary effect of taking large doses of Deca is low sperm count and low ejaculation volume. And besides that, there is also a high chance of prostate enlargement, especially in elder men. And if this was not scary enough, it may all together decrease your libido. Anabolic steroids have been known to have adverse effects on their user’s sex life.

Usually, ceasing the drug should get you back to your normal state. Obviously, this is something men who take the drug will experience. Women may experience other types of effects because of the same underlying phenomenon: increase in testosterone.

Virile Characteristics in Women

Even female bodybuilders take Deca and experience changes according to their own bodies. While men experience problems with their sperm count and libido, women experience the development of more virile characteristics like deep voice. They may also have menstrual abnormalities. This is because it increases the testosterone levels in women and affects their natural hormonal balance.

Hepatic Problems

While many of the side-effects are not life-threatening but this one may be. Deca Durabolin may cause liver abnormalities or worse, tumours. In fact, there have been reported cases of hepatic neoplasms and hepatocellular carcinomas because of high dosages.

The scary part is that tumours developed because of this drug may not be discovered until they reach the stage where they become life-threatening. And once a tumour develops, there is ample scientific proof that it may not get smaller even when the drug intake has been stopped.

Mood Swings and Depression

Addicted to Steroids

Although this is not as common as some of the other side-effects but Deca like most anabolic steroids may also have psychiatric effects. You may experience mood swings, anger or depression. This is quite unhealthy as it can affect your personal life and your relations with people around you.

It is important to mention that if you happen to have depression more frequently it is because of either a large dosage of the drug. Continuous depression, as you know, can have an adverse effect on a person’s mental and even cardiac health.


There is no doubt about the efficacy of the steroid Deca at increasing lean muscle mass and in helping bodybuilders bulk up. However, it comes with its own set of side-effects that you can never really be sure about because each body is unique and chemicals interact differently. Nevertheless, it is important to make the decision about taking steroids after knowing what it may cost you in terms of your health.

On the other hand, the severity of the side effects mostly depends on the quality of the steroid and the brand you are using. There are some top brands that offer alternatives that offer the same results but without any side effects as the products are made with all natural ingredients. So, you can still use the steroid but only from a quality brand if you want to avoid side effects.
