Proviron is the trade name for mesterolone. It is a unique anabolic steroid that offers clear advantages over other anabolic steroids. Proviron has very low androgenic properties and is taken orally. Supplements are generally not used in mass cycles, but they do play an important role in the surgical phase.

Studies show that Proviron has an excellent effect on sperm and causes male idiopathic oligospermia. This guide covers Proviron’s best cycle, including its effective dosage, benefits, and possible side effects.

What is Proviron?

Proviron is an anabolic steroid that is an oral derivative of DHT, so users do not need to inject it. This steroid is widely used in surgery and has many benefits. It was originally used to treat hypogonadism in men with low testosterone levels.

Proviron has low anabolic properties and benefits, so it is not used to supplement or increase muscle mass. It is not an effective compound that increases muscle mass. However, when used correctly with the right anabolic steroids, it offers amazing benefits. You can find Proviron here.

When users take Proviron, it binds to SHBG levels and increases available testosterone levels and increases the effects of other anabolic steroids. It strengthens muscle mass and helps to achieve the goals set for the work cycle. Users can also take Privor with other anabolic steroids like Winstrol, Anavar, Clenbuterol and Masteron.


Proviron has become popular as an anti-estrogen years ago because it has a high affinity for binding to the aromatase enzyme, so users of anabolic steroids (AS) may use it as a substitute for AI (aromatase inhibitors). Bodybuilders have used it during post-cycle therapy (PCT); Unfortunately, studies have shown that Proviron inhibits LH (luteinizing hormone) in some cases. As a result, high doses of Proviron may prevent pituitary recovery after a steroid cycle. Some users insist that Proviron does not interfere with HPTA when used in PCT or during bypass; However, this is debatable. As a side note, some studies support the long-term use of Proviron in large doses without severe suppression. Science supports the use of Proviron for PCT, but not in all cases.

Now that we have Aromasin, Arimidex and Letrozole, Proviron is outdated when it comes to using anti-estrogen. We know that true aromatase (AI) inhibitors can be used safely during post-cycle therapy and will not prevent HPTA. Although Proviron should not.


This does not mean that Proviron is not used in a cycle when you use aromatic compounds such as Dianabol, Testosterone, Nandrolone or Equipoise. In fact, the user can expect to look harder, more anxious and less swollen when stacking Proviron with a wet mixture.

Another advantage of Proviron is that it binds very well to SHBG (Sexual Hormone Binding Globulin), which is responsible for reducing the free alpha-testosterone of the farm circulating in the body. Probably because some people use Proviron during PCT.

Competitors will appreciate Proviron’s hardening properties. Because Proviron is reduced by 5 alpha and cannot produce estrogen, it contributes to a drier appearance.

Proviron on steroid cycles:

Proviron is a mild anabolic steroid. The use of Proviron seems to be limited during the cycle as new and more effective drugs and steroids are invented. It does not help with muscle growth, although it does trigger the androgen receptor.

Use it as part of a kit to inhibit the rise in estrogen levels, and use it frequently for this purpose before anti-aromatases and SERMs (Selective Estrogen Receptor Modulators) are built up. Although nowadays it is rarely used for this purpose due to SERMs as they are more efficient.

Proviron and LH

While it’s surprising that Proviron doesn’t help build muscle, the fact that it doesn’t help restore LH levels is typical of anabolic steroids.

Anabolic removes natural testosterone from the body and is therefore not useless in restoring LH levels. There is a debate here as to whether it acts as an inhibitor (like other anabolic steroids) or has no effect whatsoever.

Research tries to determine the effects, but the very nature of LH makes it difficult to study how various anabolic steroids affect it. Moderate changes in LH levels can occur minute by minute, so by the time the study is complete it is almost impossible to determine if Proviron was affected at this particular level.

This has led to misinformation and confusion in the data over the years and as such any relationship between Proviron and LH must be carefully scrutinized to help the user understand exactly what effect a steroid may have on their body.

Proviron and LH

Proviron Research

A study conducted 40 years ago in Sweden using Proviron at a dose of 50 mg per day showed an inhibitory effect that was not statistically significant as the LH area remained normal. Since then, there have been many studies that claim no effect has been found.

The problem with these studies is not the results, but the way they are presented. There is a large syntactic difference between “not statistically significant” and “no difference”. The latter is often cited as a source of misinformation for those who benefit from research.

Proviron is known to have side effects during post cycle treatment as it is a PAH inhibitor and should not be used. The goal of post-cycle therapy is to rebuild testosterone levels. Blocking them for a long time can have a serious negative impact not only on your libido.

What are the benefits of using Proviron?

Proviron is a unique anabolic steroid and offers amazing benefits when used properly with the right foundation. Proviron has a greater affinity for the aromatase enzyme than testosterone. Testosterone itself aromatizes, increasing estrogen levels and various estrogenic side effects.

Proviron works in the opposite way as it binds to the aromatase enzyme, so the enzyme affects the testosterone steroids. It reduces and increases the level of the hormone estrogen. Proviron may also contain SHBG, which blocks testosterone from binding to the sex hormone binding globulin protein. It also offers many other benefits such as:

  • Add lean muscle mass
  • Great for cutting
  • Not injected
  • Avoid the aroma
  • Improve your mood
  • Increase bone density
  • Muscle strengthening
  • Bomb effects
  • Increase libido
  • Fat loss
  • Great for cutting
  • Infertility treatment
  • Treatment of impotence

Proviron dosage information

Proviron dosages are easy to consume based on your experience. The recommended dosage and cycle length help users achieve more effective results. A typical dosage range for Proviron is 25 to 250 mg. Here is the most common Proviron dosage based on user experiences:

  • First time users: 25 mg per day
  • Moderate Users: 50 mg to 150 mg daily
  • Advanced Users: 150-250 mg per day
  • Beneficiaries: Less than 25 mg per day

Women should not exceed 25 mg per day as high doses may cause virilization in women. They also don’t take a Privoron cycle for more than five weeks, which is detrimental to their health.

Proviron Therapy post cycle

Proviron became popular as an anti-estrogen many years ago because of its high ability to bind to the aromatase enzyme, allowing anabolic steroid (AC) users to use it as a substitute for AI (an aromatase inhibitor). Bodybuilders used it during Post Cycle Therapy (PCT); Unfortunately, studies have shown that Proviron inhibits LH (luteinizing hormone) in some cases. As a result, a high dose of Proviron can prevent the pituitary gland from returning after a steroid cycle. Some users say that Proviron does not inhibit HPTA when used with PCT or while breastfeeding; but that’s debatable. In fact, some studies confirm long-term use of Proviron in large doses without severe suppression. Science supports the use of Proviron in PCT, but not in all cases.

Now that we have Aromasin, Arimidex, and Letrozole, Proviron is obsolete when it comes to anti-estrogen use. We know that true aromatase inhibitors (AIs) are safe to use during post-course therapy and do not inhibit HPTA. Although neither should Proviron.

With that in mind, it doesn’t mean that Proviron isn’t useful in a cycle that uses flavors like Dianabol, Testosterone, Nandrolone, or Balance. In fact, when folding Proviron with a wet mix, the user can expect a tighter appearance, more vessels, and less swelling.

Another advantage of Proviron is that it binds very well to SHBG (Sex Hormone Binding Globulin), which is responsible for lowering free testosterone circulating in the body. Maybe that’s why some people use Proviron during PCT.

Competitors will appreciate Proviron’s curing properties. Because Proviron is low in 5-alpha and cannot produce estrogen, it helps you look drier.

Cycle treatment with Proviron is generally not recommended for beginners and women. Higher doses of Proviron can cause testosterone suppression in men, no matter how mild the anabolic steroid Proviron is. Therefore, users should participate in cycling therapy at the end of the Proviron steroid cycle.

The ideal PCT Proviron cycle lasts four weeks. Users can use Clomid, Nolvadex and HCG for post-cyclic therapy. A good PCT cycle will give users profitability and save them from the various estrogenic side effects that occur as a result of using Proviron. It also increases the levels of the natural hormone (testosterone).

Proviron Therapy post cycle
  • Clomid: 50 mg daily for four weeks
  • Nolvadex: 20 mg daily for four weeks

Once upon a time, Proviron was considered a great alternative to post-cycle therapy. The reasons are pretty clear, as Proviron can conclude:

  • Increased sperm count;
  • Increased levels of LH and FSH (also called follicle stimulating hormone and luteinizing hormone);
  • Estrogen decreased slightly.

Today we have Nolvadex (Tamoxifen) and Clomid (Clomiphene Citrate) – all healing effects are achieved after just one cycle and do not destroy your cholesterol like Proviron. If you still want to use Proviron the old-fashioned way, you can add it to the classic Nolva PCT at a light dose: just run 20mg DE for 2 weeks and add around 25-50mg Proviron. This way you can avoid the higher dose (40 mg) of Nolva and keep your PCT short (2 weeks instead of 4).

Post Cycle Therapy or PCT as it is known in bodybuilding circles is always necessary when performing a steroid cycle.

Regardless of how good you are feeling or how low your steroids have been, you should always do PCT after a cycle.

PCT should be in the form of Clomid and Nolvadex.

It should look like this:

  • Clomiphene – 50/50
  • Nolvadex – 20/20/20/20

Possible side effects of Proviron

Proviron also has several side effects like other anabolic steroids, with prolonged use or high doses of Proviron. However, it is one of the safest and mildest anabolic steroids in high doses, and long-term use can cause a number of side effects such as:

  • Toxic to the liver
  • Alopecia (hair loss)
  • Pimples
  • Enlarged prostate
  • Deep voice in women
  • Hair growth in women
  • Increase your bad cholesterol levels
  • Testosterone suppression
Possible side effects of Proviron

Users can avoid all of the above side effects by sticking to the recommended dose and cycle length with protection. Proviron is not a 17 alpha-alkylated steroid, but oral Privoron has a very high risk of liver toxicity. Therefore, it is important to use liver protection products like LIV-52 or Samarin or SamaGen during your Proviron cycle. This protects the user’s liver from various liver diseases and injuries.
