What is Proviron?

What is Proviron?

Proviron is an entirely different concept when it comes down to what one would assume they know about steroids. After all, it is a steroid, its effects, however, are very mild and its use is very specific.

Proviron could even be considered more of a supplement than a direct steroid. After all its best use is to supplement other steroids and promote gains from other compounds. Sounds a little funny for it to be considered a steroid itself.

As far as timelines go, Proviron is one of the oldest steroids on the market. With data going back to the early 1930s Proviron was first manufactured by Schering and was used as a treatment for low testosterone diagnosis in men. 

Up until this day it has been used as a part of a PCT when releasing more free testosterone into the bloodstream means more gains can be kept post cycle. While being run on cycle with other compounds it reduces SHBG which allows more free testosterone to work its magic. 

Gains from Proviron alone are pretty much non-existent, In terms of mass and strength that is. Using Proviron alone users may feel more energy, more optimistic and generally in a better mood.

Proviron is widely available as a pharmaceutical-grade drug and is still prescribed and sold in many countries worldwide as a treatment for men with low libido or as a low testosterone treatment.

Using a c17 alpha alkylated tablet does have its downsides. Side effects can be more widespread and common when taken without precaution or run for longer and high dose cycles.

Androgenic Rating: 35

Anabolic Rating: 100

How Much Does Proviron Cost?

Users can expect to pay around £35 – £45 per 100 tabs.

What Does a Proviron Cycle Look Like?

This is where things get a little hazy. Especially considering it can be used as a part of a PCT or as a supplement to enhance a cycle. Proviron is more likely to be used as a part of cutting cycle given its ability to not be aromatised by the body.

Doses usually range from 50mg – 100mg daily. It can be used where more androgen based compounds are being run to build up levels of an anabolic compound, say if you’re running Winstrol, Anavar or Primo adding some Proviron can enhance the overall solid look of the muscle.

If you’re planning to use Proviron as a part of a PCT then 50mg per day is usually enough, when combined with Nolvadex or Clomid to promote natural testosterone production and keep negative effects away.

As with anything to do with performance-enhancing drugs, not everything works for everyone. It is important to listen to your body and see what works for you.

What Are The Side Effects of Proviron

Any drug can have side effects and steroids are no different. Side effects of Proviron can come in various ways, however, it is important to note when taking oral steroids they can affect the liver much more than injectable steroids.

Side effects from steroids can affect the cardiovascular system, estrogenic and androgenic.

When using anabolic/androgenic steroids, it is essential to understand the risks associated with the use and also how to minimise the chances of them occurring. 

It is important to note that not everyone will experience side effects from steroids. It is essential to know and understand the risk associated with them, though. 

Winstrol has also been known to be used by female competitors, the side effects for women can be much more serious and often not reversible.

We can break down the side effects of Proviron into the following subjects;


  • Estrogenic side effects
  • Androgenic side effects
  • Cardiovascular side effects
  • Hepatotoxicity
  • Natural testosterone shutdown

Androgenic Side Effects Of Proviron

The androgenic rating of Proviron is quite weak when compared to almost any other steroid and it is also primarily classified as an anabolic steroid. Yet, many people report suffering from oily skin, breakouts on the back and shoulders as well as deepening of the voice and an increase in body hair growth.

If you suffer from male pattern baldness, it is possible Proviron will increase the rate at which you are losing hair.

Estrogenic Side Effects

Proviron is not aromatized into estrogen within the body. As such users who would normally be more sensitive to estrogen-based side-effects can run it without an issue. 

Cardiovascular Side Effects

It can affect cholesterol levels by reducing HDL or ‘good cholesterol’ and increasing LDL ‘bad cholesterol’. This shift, over time, can result in the hardening of the artery walls and higher levels of fat in the bloodstream leading to strokes, or heart attacks if left unchecked and untreated.

It is highly recommended for anyone thinking about running a cycle, or who has already run one to get blood tests done at least every three months. This not only allows you to know what is going in regards to your health but also make any necessary adjustments before starting.

Does Proviron affect the liver?

Proviron does not have a C17 Alpha Alkylated structure and as such should not affect the liver. 

Natural Testosterone Shutdown 

Using any form of steroid will lead to the suppression of your natural test production. This often returns after the cycle has stopped. In rare cases or when users have been on cycle for prolonged periods, people can be shut down permanently or suffer from low testosterone levels for many years.

PCT ancillaries such as HCG can help keep the testes stimulated and producing natural testosterone. It is usually taken as a part of a PCT (post cycle therapy).

Benefits of using Proviron

  • Oral tablet, convenient and easy to take
  • Great to enhance other steroids
  • Perfect for enhancing PCT
  • No estrogenic side effects
  • Considered quite mild, suitable for first-time users


Proviron isn’t quite the mass monster we have come to know from many other PEDs on our list, yet it still does have quite a lot to offer. It is one of the most versatile compounds on the market and its ability to enhance other steroids is second to none.

One of the greatest things about Proviron is its ability to reduced estrogenic based side effects in other steroids while being combined on cycle. This makes it particularly appealing to those who are more sensitive to estrogenic sides.
