Proviron Cycle: Results, Side Effects, And Dosages

Proviron Cycle (Mesterolone) – Benefits, Side Effects, Dosages

In today’s article, we are going to be talking to you today about a Proviron cycle.

Yes, in the world of bodybuilding, there is a dirty little secret that not too many people speak of.

No, we’re not talking about Arnold’s controversial comeback Olympia win in 1980, we’re instead talking of the “S” word.

No, not that S-word, we mean steroids.

To somebody with no real knowledge about human anatomy and health and fitness in general, steroids are the devil incarnate.

The mere mention of the word renders them unable to function and results in them mumbling words such as ‘road rage’ or ‘heart attack’.

Yes, we know that steroids are very dangerous, and we also know that they’re illegal but no two steroids are 100% alike.

Some of stronger than others, some are weaker than others, and some, in all honesty, you’d be better off not bothering with at all.

Today we’re focussing on one of the more popular and effective steroids currently on the black market.

Yes, we’re looking at running a cycle.

In this guide today we’ll be looking at what Proviron is, how it works, what it does, what a Proviron may look like, dosages, side effects, and whether PCT is required once your cycle is complete.

All of these questions, and more besides, will very shortly be answered.

Key Points

  • Proviron is an old steroid used mainly for cutting, promoting fat loss, and lean muscle preservation.
  • It inhibits estrogen conversion and can improve the effects of other steroids in a stack.
  • Proviron is taken orally, with daily dosages typically ranging from 40mg to 60mg.
  • Potential side effects include liver toxicity, accelerated hair loss in those prone to baldness, and acne.
  • Post-cycle therapy (PCT) is crucial after using Proviron to restore natural hormone production.

What Is Proviron?

Results 🎯Lean muscle, fat loss, no aromatization, catalyst for other steroids.
Side Effects ❤️‍🩹Liver toxicity, hair loss, acne, potential prostate enlargement if abused.
Dosages 🧪Daily 40-60mg, maintain free testosterone, avoid suppression.
PCT Required 📚Always needed, Clomid & Nolvadex.

Proviron, or mesterolone, is one of the oldest androgenic anabolic steroids currently on the market today.

It was created by a company known as Schering, who back in the 30s, was as big in the pharmaceutical industry as Apple is in the tech industry now.

That’s right, this steroid was first available on the market back in 1934.

That is pretty remarkable when you stop and think about it, as it means that it has been around before WW2.

Over the many years, it was available, it was marketed under many different names.

Despite this, Proviron still remained the most popular and it is Proviron how it is known to this day.

Though very unique, it shares a few similarities with Masteron, along with Winstrol and Anavar.

If you know your steroids, you’ll know that compared with the big boys like Tren, these steroids are actually quite mild.

You might like to check our article about Deca VS Tren.

Mild yes, but there are still powerful enough to provide impressive results and they can still do some damage.

Needless to say, this gives you an idea that Proviron is perhaps not as powerful as other steroids. It is, however, still very unique in its own way.

This steroid is not designed to be used for bulking purposes so if you want to become the next mass monster and pack so much size on that you’d give a prime Markus Ruhl a run for his money, Proviron isn’t for you.

It promotes lean muscle mass and fat loss and is, therefore, a great addition to many cutting stacks.

The FDA never actually approved this drug for therapeutic use, though it was approved in many parts of Europe.

It was used to treat androgenic deficiencies and can be used to treat a wide range of fertility issues, especially in men.

This steroid is a structurally altered DHT hormone that possesses the methyl group located at the carbon one position.

It is an oral steroid, it carries an androgenic rating of 30 – 40 and an anabolic rating of 100 – 150.

This rating is compared with testosterone, which in both categories, carries a rating of 100.

Proviron Benefits:

Now it’s time for us to take a look at a few common benefits associated with Proviron usage.

These include the following:

Fat Loss

If you want to pack 40 pounds of muscle in a single steroid cycle, Proviron isn’t the right choice.

It promotes marginal increases in lean muscle tissue, primarily by increasing core temperature, speeding up metabolism, and aiding in burning off stubborn body fat.

For those seeking to get lean, either before a show, a holiday, or just because, Proviron is hugely beneficial, making it one of the top fat-burning anabolic steroids.

Proviron is great for burning fat, leaving you looking leaner and slimmer than ever.

Great For Cutting

As many bodybuilders will know, the most challenging phase of any contest prep is the cutting period.

During this stage, the bodybuilder’s primary goal is to burn off as much fat as possible while preserving lean muscle mass.

Proviron is a valuable steroid because it promotes lean muscle growth and helps maintain existing muscle, all while boosting metabolism and burning body fat in a caloric deficit.

Inhibits Aromatization

One of the challenges with anabolic steroid use is the process called aromatization.

This is when testosterone in the body, or from the steroids themselves, converts into Estrogen, leading to issues like weight gain, water retention, hormonal fluctuations, and gynecomastia.

It also triggers the production of cortisol, a stress hormone with anti-anabolic effects.

Notably, Proviron, unlike most anabolic steroids, does not undergo aromatization.

In fact, it actively inhibits this process by binding to the responsible enzyme and preventing aromatization, offering increased protection against Estrogenic side effects.

Increased Lean Muscle Mass

Okay, while it won’t pack anywhere near as much muscle onto your frame as Anadrol, Trenbolone, Dianabol, or other powerful steroids, this is still an androgenic anabolic compound that has the ability to promote increases in lean muscle mass.

If you use this steroid and continue to eat right, work hard in the gym, and lead a healthy lifestyle, you will notice improvements in your physique which will become more noticeable with each passing week.

On average, you can expect around 10 pounds of lean muscle from a cycle, which is certainly nothing to be sniffed at.

Building this amount of muscle naturally would take years, rather than months.

Improved Effects From Other Steroids

For best results, bodybuilders often stack Proviron with other anabolic androgenic steroids.

There are two key benefits to combining Proviron with other anabolic steroids.

The first is its ability to prevent Estrogenic side effects, as mentioned earlier.

The second advantage is that Proviron acts as a catalyst for the other steroids in your stack, enhancing their effectiveness.

This occurs because Proviron possesses a high binding affinity to the androgen receptors in your body, ultimately making both Proviron and the other steroids in your stack more potent.

No Injections

Not everybody likes sticking a needle in their skin, and if you’re one of those people that hate needles, you’ll love the fact that this is an oral steroid.

You can check more about this on our Oral Vs injectable steroids case study.

It is therefore taken in tablet form and is simply swallowed in the same way that you’d swallow a painkiller if you had a headache.

Proviron Cycle (Mesterolone) – Benefits, Side Effects, Dosages

Proviron Cycle:

Now it’s time for us to take a look at a sample cycle for you to consider.

Remember, it all depends on what you want to get from your cycle and what your goals may be.

The following, however, does give you a general idea of what you should be running:

Cycle 1

Proviron Side Effects:

Now it’s time to address some of the less glamorous aspects of anabolic steroid use, specifically the side effects.

While Proviron is considered safer than many other real anabolic steroids, it can still pose serious health risks if abused. Common side effects encompass:

Liver Toxicity

As is the case with all oral steroids, even with Halotestin, one of the most severe side-effects you will need to watch out for is liver toxicity.

Oral steroids are notorious for damaging the liver.

This is because, unlike oil-based injectable steroids, oral steroids do NOT bypass the liver.

They pass through the liver and cause damage on their way through.

This is why PCT should always be used and it is why on-cycle support in the form of a Milk Thistle supplement, should always be used.

Baldness Issues

If male pattern baldness runs in your family, using this steroid could result in you losing your hair at a much faster rate than you would without it.

It does not, however, cause hair loss (RU58841) in everybody.

If you are not susceptible to hair loss, your head of hair will still remain perfectly intact.


Proviron is widely known for its potential to influence the androgen receptors, particularly in skeletal muscle tissues.

When using Proviron, it’s crucial to understand its impact on androgen receptors and its ability to enhance muscle density and muscle tissue.

However, this steroid also has a downside, as it can stimulate the accumulation of oils on the skin, which may result in acne development, affecting many steroid users.

This surplus of oils can clog pores, leading to unwanted estrogen-related side effects such as skin blemishes. Steroid users often face breakouts on the face, back, and shoulders.

Therefore, a stringent hygiene routine is essential for Proviron users to minimize acne risk and focus on optimizing muscle tissue growth without concerning themselves with liver damage or unwanted estrogen levels.

Enlarged prostate

Okay, this next side effect is only true in people who actively abuse this steroid.

If you consume more than you should and use it at the wrong times, it can result in the prostate gland becoming enlarged.

This can leave you susceptible to other health issues, including an increased risk of prostate cancer.

The moral of the story here is that you should never abuse steroids.

Proviron Dosage:

To reinforce your understanding of the information we’ve covered, let’s revisit typical Proviron cycle dosages.

Whether you’re a newcomer or experienced in the realm of steroid use, these guidelines are essential to remember.

As an easily absorbed oral steroid, Proviron is typically taken daily.

The recommended dosages usually vary between 40mg to 60mg per day, which can contribute to maintaining and optimizing free testosterone levels and enhancing overall testosterone production without the need for more complex treatments like testosterone replacement therapy.

This ensures that natural testosterone production remains active, helping to maintain healthy testosterone levels and avoid any potential testosterone suppression.

For those seeking to enhance their physique, these steroid cycle dosages are crucial to follow.

Most Unique Anabolic Steroid: Proviron

Proviron, an androgenic anabolic steroid, plays a unique role in the world of bodybuilding. It has characteristics that set it apart from many other steroids.

Proviron works by inhibiting estrogen conversion and promoting fat loss while preserving lean muscle mass. It is also known to boost the effects of other steroids when used in combination with them.

Additionally, Proviron doesn’t undergo aromatization, reducing the risk of estrogen-related side effects. This steroid can promote increased lean muscle mass, making it a valuable addition to bodybuilders’ cutting stacks.

Is PCT Required?

Post Cycle Therapy , or PCT as it is known in bodybuilding circles, is always required when running a steroid cycle.

It doesn’t matter how great you feel, or how weak the steroids were, you should always run PCT after ending a cycle.

It should look something like:

Clomid – 50/50

Nolvadex – 20/20/20/20


How many mg of Proviron should I take?

The typical daily dosage of Proviron ranges from 40mg to 60mg, depending on your goals and experience.

What is a Proviron Cycle?

A Proviron cycle is a period of using Proviron, typically in a bodybuilding context, to achieve specific fitness goals like fat loss and muscle preservation.

Can Proviron boost sperm?

Proviron may have some potential in boosting sperm count and fertility in men, but it should only be used under medical supervision for this purpose.

Hi Reda,
Love your insightful articles.
I have few enquiries if you don’t mind; what results should one expect from a proviron + dianabol cycle?
Dosage and duration for pct?
When to incorporate arimidx if I should?
Should my food intake be on a surplus or not if I look to benefit from an increase in lean muscle

Many thanks

Incorrect……..Proviron is NOT damaging to the liver despite it being an oral steroid. It is NOT a c17 methylated steroid (probably why its not more effective too). Even under heavy use, it has shown no damaging effects to the liver in all studies.

This is very there are many forums and sites claiming this and its not accurate, and yes its not a C17 methylated steroid so wont harm the liver, this gets to me same as when people say I’m gonna inject winstrol since its not an oral it wont pass through the liver wrong!! its a c17 methylated compound regardless if you inject it take it orally or even drink it lol

You probably believe that a white diaper over your face will protect you from microscopic size molecules
like the people I laugh at the riding a bicycle with a helmet on the beach and they have a mask on their not protecting their hands their knees or their elbows with the most likely to get hurt in a crash but they’re protecting themselves from coronavirus. They ride in the street with no lights and no mirrors and getting people’s way those are the Mindless dead

Pelle, you are seriously a major disappointment to your parents and extended family. If you can’t understand people wearing masks in an attempt to prevent a pandemic then you are just an asshole who is probably extremely lonely and will never get laid, never get invited to a party, never have any real friends etc. etc. I almost feel bad for you but then I remember, you’re an asshole.
How does anything in this article or anything anyone talked about have to do with wearing masks or bicycle helmets? You were just itching to get into a fight about something so pointless and about people wanting to try and protect their families health.
Get a life you. You are such a pitiful loser I can’t imagine being so delusional.

Coming from a libtard that wears a useless face diaper by himself driving his car after getting his 9th injection and just got over his 5th case of covid. Vaccine works, its you unvaccinated people that are the problem. But we never wore a face diaper, never got a shot and got a cold like the old days.🤡😂🤡😂
