Proviron, also known as mesterolone (C₂₀H₃₂O₂), is an oral anabolic steroid that shares some very strong similarities with Masteron.
It was one of the first anabolic steroids introduced to the medical industry and was produced in 1934 by the Schering pharmaceutical company.
Though other companies have created mesterolone under different brand names throughout the years, Proviron is still the best known and the most popular.
Profile – What Is Proviron?
The steroid is by far one of the most unique, and while it is not used for mass gains and bulking, it may play an important role during the off-season bulking phase. It is more commonly introduced into cutting phases, though once again, its function is quite unique in this case, as well.
People buy Proviron as it is a very commonly prescribed anabolic steroid in many countries, particularly in Europe, but has never been approved by the US’s FDA for medical treatments.
Proviron is derived from DHT, and although it is an oral steroid, it is one of the very few that is not alkylated. This means that the steroid can be added to cycles with other oral steroids without fear of increased liver damage.
However, its lack of alkylation means its bioavailability is significantly affected. Many bodybuilders and athletes do not use for this reason, but this is often a mistake. It can play vital roles in any steroid cycle.
In a bulking phase, Proviron does not directly affect Muscle Growth. However, it can enhance the action of other anabolic steroids, helping them work better, and thereby boosting their results.
Many, many athletes have found that adding it to a bulking stack can help them surpass plateaus without increasing steroid doses to extreme levels, as well. This means that bodybuilders and athletes can get more out of lower doses of other steroids.
For cutting purposes, bodybuilders may buy Proviron for its hardening effect, but because it binds so snugly with the androgen receptors in the body, it also stimulates the fat burning process more than most other steroids – and it may, in fact, even surpass Clenbuterol in this regard.
It is also a mild Anti-Estrogen, and while it is nowhere near as powerful as an aromatase inhibitor like Arimidex, it’s anti-estrogenic nature can help ward off things like libido changes, mood swings, and bloating during a cycle. Many men use it to increase their libido for just this reason.
Proviron Dosage and Warnings
The dosage you will need depends on your unique goals and your tolerance. Whereas most steroids that fall into this same category are safe for women, that is not the case with Proviron.
You may read stories of some women using low-dose with a great deal of success on forums, but it should be noted that because of its androgenic nature, the risk of virilization is very great. For this reason, women should avoid Proviron and instead stick to a less androgenic steroid like Anavar or even Primobolan.
With that in mind, men can use a wide range of dosage options. When they buy Proviron, they should consider their needs and tolerance, then purchase enough to complete an entire cycle. The chart below provides a great starting place for anyone interested in learning more about how to take.
|Goal||Reason to Use||Mon Dose||Max Dose|
With the above information in mind, the real reason why bodybuilders and athletes should continue to buy – even despite its rather low bioavailability – is the fact that it can burn significant amounts of fat, even in the midst of a bulking cycle.
At the same time, it will enhance the effects of any other steroid paired with it to the degree that men may be able to use lower dosages and still get the same desired results.
Proviron is quite mild, and it is not hepatotoxic despite its oral delivery, so the risk of extremely severe side effects is quite low.
Nonetheless, the side effects should always be in the back of your mind. They range from mild to severe. Side effects do not include those of an estrogenic nature, which means it cannot cause Gynecomastia when used in a cycle alone.
Most of the side effects are androgenic in nature. This steroid has a relatively high androgenic rating, which means some users may experience things like oily skin, acne, and even accelerated hair loss in men who may be genetically predisposed to male-pattern baldness. Of all the side effects, hair loss seems to be the most concerning. However, it does not directly cause hair loss.
Of course, like all anabolic steroids, there is also some risk of worsening lipid profiles when using Proviron. Men who have high cholesterol to begin with may want to avoid using this (and other) anabolic steroids until cholesterol levels have been controlled appropriately, and men who are otherwise healthy will need to eat a healthy diet rich in omega fatty acids to keep their cholesterol under control, as well.
In women, it can lead to severe virilization, even at low doses. Excess body hair growth, deepening of the voice, clitoral enlargement, and more will almost surely occur, and these are often irreversible.
Other steroids are far better suited for women’s needs, so use should be avoided in favor of these. Winstrol, Anavar, and Primobolan are all outstanding alternatives to consider.
One of the most unique things about Proviron is the fact that it stacks with almost any steroid fantastically. It boosts that steroid’s affinity, making it much more potent without the need to increase its dosage.
For Bulking phases, simply stack with steroids known for providing tremendous gains, which include Dianabol, Trenbolone, Deca Durabolin, and others. Because it is not hepatotoxic, there is no concern about stacking oral compounds in this case.
For cutting, it may be stacked with Winstrol, Anavar, and other compounds known to help maintain lean muscle mass during times of caloric deficiency.
The steroid will enhance the body’s ability to burn away unwanted subcutaneous fat, and the Winstrol or Anavar will promote muscle maintenance, hardness, and definition all at the same time.
It is vital to stack with testosterone in order to ward off the side effects associated with low levels of testosterone. It binds to testosterone receptors, which will effectively “shut off” your body’s ability to make its own testosterone.
By supplementing with exogenous testosterone, you’ll avoid these side effects, which may include fatigue, weight gain, sexual side effects, and more.
How to Create a Proviron Cycle
You can find Proviron to add to just about any cycle, but it is far more popular for cutting. If you are a beginner who is new to anabolic steroids, It may be a great starting place for your first cutting cycle.
A Proviron only cycle is not recommended; though it is mild, it does suppress testosterone production. For this reason, you should always include exogenous testosterone at doses between 350mg and 500mg each week if you are a beginner. Increase your dose gradually throughout your cycle until you reach the maximum dose (150mg each day) or the side effects become bothersome.
For intermediate and more advanced steroid users, a cycle may look like this:
This cycle is perfect for burning fat and hardening muscle, particularly when you’re on a calorie-deficient diet and interested in gaining outstanding muscle definition.
Steroids you stack will suppress your body’s natural ability to produce testosterone. Because of this, you will need to implement PCT after your cycle to boost testosterone production, reduce the effects of estrogen, and maintain your muscle mass.
PCT is relatively simple; when you buy Proviron, be sure to also pick up enough Clomid or Nolvadex to complete up to six weeks of PCT. Here’s how it would work:
- Clomid – 150mg each day for two weeks, then 100mg each day for another two weeks. If necessary, go down to 50mg a day and continue for another one to two weeks to counteract low-T and prevent estrogenic effects.
- Nolvadex – 40mg each day for two weeks, then 20mg each day for another two weeks. If you feel it is necessary, reduce the dose to 10mg a day and take it for another week or two.
You should only use HGH during your PCT if you used it on-cycle as it takes up to 12 weeks for it to have any effect. If you used HGH during your cycle, continuing it at a dose of 1IU to 2IU daily until you have completed your SERM will serve you well.
You will find tablets 25mg more than any other form, and this makes dosage simple. For example, if you will take 50mg each day, you can take both tablets in the morning (or just before a workout), or you can take one tablet in the morning and the other just before your workout.
Be sure to avoid taking it in the late afternoon or evening as this can cause some sleep disruptions.
There are some fears that Proviron and libido simply do not go hand-in-hand, and men are often afraid they will completely lose their sex drive if they buy Proviron for their performance enhancement needs.
In fact, It is prescribed in other countries as a male fertility drug. Does it increase libido? It certainly has in clinical trials, so there’s no reason to believe it can’t help you, as well.
Again, unless you are genetically predisposed to male-pattern baldness (meaning your father, grandfather, brothers, or other relatives are losing their hair), then there is no need to worry about side effects like hair loss.
However, if your hair is thinning, or if you have balding relatives, be aware that Proviron may very well speed this process.
Another common fear men express when shopping for Proviron is the fear of erectile dysfunction.
Erectile dysfunction is a common topic of discussion in forums, but again, there is nothing to fear. In fact, men who have erectile dysfunction before using steroids often find that it can reverse it to a degree, which provides them with a happier sex life.
It is thought that since it acts much like testosterone in the body, and testosterone plays such a major role in your ability to achieve and maintain a quality erection, Proviron can actually improve your erections.
If you live in a country where steroids are legal, it is not difficult to buy Proviron at all. In fact, you can probably find Proviron for sale in numerous pharmacies and drug stores.
However, if you live in the US, UK, and certain other countries where steroids are illegal without prescriptions, you may find it more difficult to buy.
The internet is often a good source, and you may find shippers willing to send to you through the mail. This is quite risky, though, and it may lead to legal trouble. Learning where to buy tablets can be tricky, so it’s vital to do your research.
It is not FDA-approved in the US, so you cannot buy Proviron online from any American seller. With that in mind, some forums have noted that a handful of merchants may ship to countries such as the US, but for many people, the legal risk is not worth the hassle.
Most people in the US buy Proviron from underground labs that process their own pills. Sometimes, though, these pills are counterfeit and not the proper strength, so it is important that you trust the seller.
Like almost every other anabolic steroid out there, if you are an otherwise healthy man who has no underlying medical conditions, you buy legally, and you use it according to the recommended guidelines, you can mitigate much of the risk associated with this steroid altogether.
You should not use if you have underlying medical conditions or if you are a woman as the risk is far too great.
