Key Takeaways
- Deca Durabolin can cause erectile dysfunction, commonly known as deca dick. 😬
- Deca dick can last anywhere from a few weeks to several months. ⏳
- Testosterone shutdown is a significant factor in the onset of deca dick. 🚫
- Incorporating testosterone or using PCT might help prevent deca dick. 🛡️
- Despite the risks, Deca Durabolin is popular in bodybuilding for its muscle-building benefits. 💪
Deca is a steroid often used by bodybuilders in the off-season to help them bulk up and pack on huge amounts of size and mass.
Deca is short for Deca Durabolin – also known as nandrolone.
Deca became very popular during the 70’s and 80’s. Arnold, Mike Mentzer, and Lou Ferrigno are some of the big names who were thought to be running deca during this golden era.
Thus it’s fair to say that deca durabolin has helped build some of the best physiques in bodybuilding history.
Deca Durabolin Gains
If you’re after huge muscles with insane thickness, Deca Durabolin is your go-to. This steroid is famous for packing on size and creating that full, solid look every bodybuilder dreams of.
But there’s more to Deca Durabolin than just muscle gains. It’s also known for a not-so-fun side effect: deca dick.
Now, you might be wondering, “What is deca dick?” Simply put, it’s a frustrating form of erectile dysfunction that can really mess with your game.
This happens because Deca increases prolactin levels, which can lead to a drop in testosterone and cause some issues in the bedroom. But don’t worry, we’ll get to how to avoid deca dick in just a bit.
For those considering a Deca only cycle, it’s important to know that while your muscles will grow, your libido might not keep up.
This is why many stack Deca with testosterone to help balance things out. But keep in mind that even with this stack, the sus and deca side effects are something to watch for.
So, is deca dick permanent? Not usually, but it can last for a while—sometimes up to three months.
Now, let’s talk about what you can expect from a Deca Durabolin cycle. You’ll see gains in both size and strength, and unlike other bulking steroids, Deca doesn’t cause excessive water retention.
This means your gains will be more about lean muscle and less about puffiness. It’s one of the reasons Deca Durabolin reviews are generally positive.
But let’s circle back to deca durabolin libido. Yes, Deca can decrease your libido, but stacking it with the right compounds can help.
Also, there are ways to manage deca erectile dysfunction during your cycle, ensuring you don’t experience the dreaded deka dick or decadick.
High-profile modern day bodybuilders who have this thick (deca) look are:
- Bradley Martyn
- Chul Soon
Here’s a couple of images of Bradley Martyn and Chul-Soon displaying this huge/thick look:


Deca Durabolin Side Effects
As far as steroids go, deca durabolin is considered a fairly healthy one.
In fact, some doctors even recommend people with joint problems cycle deca, due to its BMC boosting properties.
BMC = Bone mineral content.
Many other steroids can cause aching/sore joints, making Deca a great steroid to take when running other steroids causing you these side effects.
Deca also boosts collagen levels, helping improve the quality of your skin and prevent accelerated aging (associated with other steroids).
Deca only aromatizes at a modest rate, meaning you’ll retain less water than other steroids. Deca actually aromatizes at approximately 20% of what testosterone sustanon does.
Thus the weight you’ll gain on deca will mostly be lean muscle tissue, as opposed to water retention. Many people believe deca isn’t anywhere near as powerful as Dianabol for building muscle because a user might gain 35 lbs on Dianabol and only 20 lbs on Deca.
However, Dianabol is known to cause a fair amount of water retention, so 15 lbs of the weight you gain on D-Bol might be water retention. Whereas deca may only cause 5 lbs of water retention.
So in the above scenario, Dianabol is only slightly superior to deca when it comes to packing on size; building 5 lbs more muscle.
What About Deca Dick (Erectile Dysfunction)
Let’s talk about deca dick, a term you might have heard before.
It’s essentially erectile dysfunction that can be triggered by using Deca Durabolin.
If you’ve seen the movie Pain & Gain, you might recall the scene where Adrian (played by Anthony Mackie) tries to get intimate but can’t, due to his lack of action down there.
That’s a classic example of decca dick.
The main culprit?
Deca Durabolin can cause this because, like all steroids, it shuts down your testosterone production.
But with Deca, it’s more common and can even show up early in your cycle, unlike with other steroids where libido issues tend to appear later.
Some users find themselves stuck with deca dick for up to three months or more, with everything feeling “frozen” down below.
If you’re lucky, though, it might clear up in a month or so. But naturally, you’re probably wondering, “Does deca dick go away?”
The answer is yes, it usually does, but the timeframe varies from person to person.
You might also be thinking, “Does Deca Durabolin cause erectile dysfunction more often than other steroids?”
Unfortunately, the answer is yes, it does.
This is because Deca increases a hormone called prolactin, which interferes with your sexual function.
This could lead to lower testosterone levels, which in turn causes deca dick.
So, what causes deca dick?
It’s a combination of low testosterone and high prolactin levels.
Now, you might be curious, “Does Deca Durabolin increase libido at all?” Surprisingly, Deca can increase your libido at the beginning of your cycle. But as prolactin levels rise, this boost can quickly turn into a problem.
Deca Durabolin might give you impressive results, but you also need to consider the deca side effects.
Understanding these risks can help you figure out how to avoid side effects of Deca-Durabolin and keep your body in check.
As you weigh your options, check out a Deca Durabolin review or two.
These Deca Durabolin reviews can give you a better idea of what to expect from a Deca and test cycle.
They’ll also clue you in on how other users have managed deca libido issues and whether they’ve found ways to prevent or manage deca dick.
So, does Deca Durabolin really live up to the hype? And does Deca cause ED in every user?
That’s something you’ll need to weigh carefully before jumping into your next cycle.
What Causes Deca Dick?
Deca increases a hormone called prolactin, significantly more than other steroids that aromatize T.
The excess prolactin interferes with the secretion of gonadotropin-releasing hormone, resulting in decreased testosterone and erectile dysfunction.
Deca also reduces DHT, a crucial hormone for erections; due to it increasing nitric oxide production inside the penile tissue, sparking morning erections.
This is also the reason why drugs like finasteride, used to prevent hair loss in men, are often associated with sexual health problems, including impotence.
How to Prevent Deca Dick from Happening?
Simple – do not use anabolic steroids.
Some steroid users stack it with others such as testosterone, which might reduce erectile dysfunction during the cycle but eventually, it will further aggravate the overall damage to the body.
Caberglobin (Dostinex)
Dostinex is a drug used to treat hyperprolactinemia (when there’s too much prolactin in the bloodstream). This is essentially what happens on Deca Durabolin.
Thus steroid-users often combine ‘dost’ alongside deca Durabolin during cycles.
People on Dostinex often report very strong erections and their libido going through the roof (having multiple orgasms during intercourse). This is the perfect drug to combat deca dick.
You can get this via a prescription from your doctor if he tests your prolactin levels, and they’re excessively high.
Where to Buy Deca From Online?
Crazy Bulk manufactures a legal steroid called Decaduro, which mimics the effects of deca durabolin (without the side effects).
Decaduro has received a lot of positive feedback online and has a 5 out of 5 review on the Crazy Bulk website.
Here’s a transformation of a Crazy Bulk customer who used deca in the bulking stack:

Deca Durabolin Results: Before and After Pictures
Deca durabolin is a steroid primarily used for bulking. For those who don’t know too much about deca, here’s what you can expect from taking the steroid:
- Huge increase in muscle size
- Huge increase in strength
- Exceptional muscle fullness
…And it does all of this without causing too much in the way of side effects.
So when you take deca you won’t be playing Russian roulette with your health like you might with other bulking compounds such as anadrol.
And with deca you won’t retain much water either, making it a very aesthetic steroid, perfect for ‘lean bulking’.
…Basically meaning you’ll look like a Greek-God taking deca on a bulk instead of a fat mess.
Deca is similar to testosterone sustanon in the sense that it can give a user huge muscle/strength gains, without causing harsh side effects.
Deca and test are the only 2 bulking steroids I can say this about.
Trenbolone, injectable Dianabol, and Anadrol are the baddies that you should stay away from if you’re anxious about steroids’ side effects.
Typical Deca Durabolin Results (Before & After)
Bradley Martyn is a well-known bodybuilder online who went from being a natty dude with good genetics; to a global icon.
…who is a beast by the way.
Bradley is thought to be taking Deca due to his huge, thick muscles which deca is famous for creating.
When somebody is on deca, it’s usually pretty obvious. Guys can experience similar gains in terms of strength and size from other steroids, but the muscle fullness/thickness on Deca is leaps and bounds ahead of any other compound on the planet.
It’s an extra dimension of thickness that no other steroid creates and makes you look a lot bigger than you are.
Look at another picture of Bradley Martyn below, where this muscle thickness is obvious…

Deca was also used by Arnold – who had great success combining it with Dianabol. This combination helped him build extremely thick biceps and pecs, enabling him to dominate the sport and become the greatest bodybuilder of all time.

How Much Muscle Will You Build on Deca?
If you’ve never taken steroids before, the best steroids for a beginner are:
- Deca
- Testosterone
- Oral Dianabol
If you want to really maximize your gains on deca it’s to combine it with either testosterone or dianabol (oral).
Stacking deca with testosterone/dianabol will help you build around 30 lbs of lean muscle from your first cycle.
If you’ve done a few cycles already, but you’ve never used deca; expect to gain an extra 10-15 lbs of lean muscle tissue. This is actually a significant amount of muscle for a bodybuilder who’s been around the block a few times…and has consumed various cocktails of steroids.
Another bodybuilding great who was thought to be using deca throughout his career was Flex Wheeler. Flex is arguably the greatest ever bodybuilder who didn’t win an Olympia title.
Deca-Durabolin Cycles
Anadrol and Deca Cycle

Once someone has cycled Anadrol before and wants to take a more potent stack, but without a lot more side effects; Deca Durabolin is a worthy addition, as it is a mild compound.
Although natural testosterone production will become more suppressed and water retention may increase, the inclusion of deca does not greatly add to the negative effects of Anadrol. Also, deca Durabolin’s most famous side effect is deca dick (erectile dysfunction).
This is partly caused by it reducing DHT levels, which is crucial for nitric oxide production and blood flow inside the penis.
Thus, with Anadrol being a particularly androgenic steroid, this will prevent this and enhance sexual health, compared to taking deca alone.
Sexual function usually declines at around the third week on deca, thus Anadrol is added around this time, due to its androgenic attributes.
Deca is a slow-acting steroid, thus is usually cycled for up to 10 weeks, allowing enough time for it to peak in the bloodstream and have an effect.
Dbol and Deca Cycle

The above cycle will be less troublesome compared to Anadrol and testosterone stacked together, however, it will almost match the strength and size gains.
Blood pressure should be monitored and a PCT will need to be implemented to recover endogenous testosterone production; but as far as bulking stacks go, this is one of the best in regards to side effects.
This is thought to be Arnold’s favorite stack, helping him to win Mr Olympia 7 times and dominate bodybuilding. Huge, full-looking muscles are a certainty.
Deca Durabolin Cycle Facts
Here are some facts you should know before running a Deca Durabolin cycle.
It Causes An Increase In Appetite
As effective as this steroid is for building lean muscle tissue, if you’re using it during a cut, it can be counter-productive.
This is because Deca causes a big increase in appetite, meaning you’ll crave food more than ever and will struggle to feel full. If you’re bulking this is perfect, where a calorie surplus is optimal for maximum muscle gains.
Thus, if you struggle to put on size, this increase in appetite is a blessing. But if you’re trying to keep your body fat percentage on the low-side, you might need to be cautious about how many calories you consume on deca.
One of the Best Steroids for Size & Strength
Building strength and muscle size are 2 of the main goals for a bodybuilder, especially in the off-season.
If you want to gain a tonne of muscle and become as strong as an ox – deca is the steroid to take.
When using Deca, it’s not uncommon for users to gain as much as 30 pounds of solid muscle from a cycle.
Dosages of course vary, but studies have found that even tiny dosages of around 100mg every 14 days, can still produce notable increases in lean body mass.
Deca Encourages Nitrogen Retention
One of the main reasons why deca durabolin can build large amounts of muscle is because of its effect on nitrogen.
Deca helps the cells within your muscles retain more nitrogen, which is crucial for the muscle-building process. Greater levels of nitrogen retention creates a more anabolic environment in the body, helping to synthesize more muscle tissue.
Deca Is Great For Your Joints
One benefit of running a Deca Durabolin cycle is that it’s great for your joints.
Bodybuilders especially, suffer from painful joints as they grow older, because they’re heavier than the average person, due to them carrying more muscle.
Deca, however, is very useful because it stimulates collagen synthesis within the joints, helping them to become more lubricated and supple.
Collagen helps to cushion the joints and provide a protective layer for them.
This in turn means less pain and discomfort, and increased levels of flexibility and resistance to wear and tear.
Deca Boosts Red Blood Cells
The more red blood cells we have, the more oxygen/nutrients that are transported around our bodies via the bloodstream.
What does this have to do with bodybuilding?
Studies have found that deca naturally increases our number of red blood cells.
This in turn helps improve our circulation and overall health, as well as improving our performance in the gym. This means huge pumps during workouts and more endurance; helping you complete more sets and reps than before.
Deca Can Shut Down Testosterone Production
When running any steroid cycle, it’s always recommended to run a PCT (post-cycle therapy). This helps to ensure you don’t experience any adverse side effects that prolong after a cycle.
Deca, like with most other steroids, will shut down natural testosterone production within the body.
Testosterone is highly anabolic and plays a key role in muscle growth and repair, thus by running a PCT you’ll be able to elevate this hormone quicker than normal.
Note: Even when taking a low dose, deca can shut down your natural testosterone production.
Because of this, deca can cause a reduction in libido and sexual performance.
To combat this, deca can be stacked with testosterone, ensuring your test and libido stay intact.
Deca is Better For Your Organs
A lot of steroids have high toxicity rates, meaning they can damage the organs, especially the liver and kidneys.
Deca, however, is a lot more kind to your organs and is considered far less potent.
If used correctly along with a PCT, there should be no real damage to your major organs, which is a big positive.
Clomid is an Effective PCT For Deca
In most cases, either Nolvadex or Clomid will work equally as well for a PCT.
However, things are a little different with a deca durabolin cycle.
You see, deca interacts with receptors in the body, increasing progesterone and prolactin receptors. Nolvadex also increases these 2 hormones.
The idea with a PCT is to help restore hormone levels and get them back to normal after you finish a steroid cycle, not to further imbalance your hormones.
Nolvadex therefore, will fail to restore these hormone balances, which is why Clomid is usually run instead.
For example, if you were to experience prolactin-related gyno from taking deca durabolin and you took nolvadex – this side effect would only get worse.
Wondering What to Stack Deca With?
In order to experience the most gains on deca, it’s recommended to stack it with other powerful bulking compounds.
Single steroid cycles can be effective, but you’re almost certainly cutting your gains short.
Steroids that work synergistically well with deca are:
- Dianabol
- Testosterone
- Trenbolone
Stacking these 4 steroids together in an 8-week cycle can usually result in 30lbs of lean muscle.
As a result of reading this article, I hope you’ve learned a few new things about deca, a truly unique and powerful steroid.
Final Thoughts
In the world of Deca Durabolin bodybuilding, the results can be incredible, but the side effects like deca dick are something you can’t ignore.
The question on everyone’s mind is, “Does deca dick go away?”
The answer is yes, but it can take time, and not everyone experiences it the same way.
So, does Deca cause erectile dysfunction more than other steroids?
Unfortunately, it does, due to its impact on testosterone and prolactin levels.
Understanding this before starting your cycle can help you manage expectations and plan accordingly.
Remember, while Deca Durabolin can help you achieve your goals, it’s important to consider the full picture, including potential side effects.
Always weigh the pros and cons, and if you choose to use Deca, make sure you’re prepared for what might come with it.
Your gains are important, but so is your overall health.
FAQs
Can Deca Dick be Avoided (Without Taking Dostinex)?
Deca dick usually occurs in the 3rd/4th week when taking doses of 400mg or higher. Deca-only cycles are very likely to cause deca dick, as high doses will need to be used to experience good gains; and there’s no androgenic compound in the stack to keep DHT levels high.
What Are The Best Steroids For Sexual Function?
Generally, all steroids enhance sexual function during a cycle, and then post-cycle, it typically declines. This is due to a crash in testosterone, as exogenous testosterone has been discontinued, and endogenous testosterone levels are shut down.
The best steroid for sexual function is possibly Anavar or Primobolan, as these two steroids will not completely shut down natural test levels. Instead, they will just cause a modest decline, thus sexual performance is not greatly impacted.
In terms of bulking steroids, testosterone is possibly the best steroid for maintaining a high libido and strong erections; as it doesn’t greatly affect prolactin levels. However, endogenous testosterone will still be low post-cycle from taking the test, thus a PCT remains essential during this phase.
Does Deca Durabolin cause erectile dysfunction?
Yes, Deca Durabolin can cause erectile dysfunction, often referred to as “deca dick.” This is due to its effects on testosterone and prolactin levels, which can impact libido and erection quality.
How long does deca dick last?
The duration of deca dick varies from person to person. It can last anywhere from a few weeks to several months, depending on how your body responds and recovers after the cycle.
Can you prevent deca dick while using Deca Durabolin?
While it’s not guaranteed, some users manage deca dick by incorporating testosterone into their cycle or using post-cycle therapy (PCT) to restore hormonal balance. Always consult a healthcare professional before starting any cycle.
