Proviron is the most famous brand name for the Mesterolone.

So, this is a sex hormone and androgen hormone playing an extremely important role in the proper formation an development of male genitals and many other men like traits. This compound is mainly prescribed by doctors to men suffering from low libido, but is also used as a precursor to full Testosterone Replacement Therapy (TRT) and also can be helpful for depression, lack of sex drive, unipolar, bipolar and others.

The compound is considered highly androgenic and with extremely low anabolic activity, in fact is so low that is considered practically inexistent. Due to high androgenic and low anabolic activity, Mesterolone found in Proviron or Provibol is not as famous as other steroids when it comes to bodybuilding uses, nonetheless, the compound is still used by some as an aromatase inhibitor (AI).

How Long Does Proviron Take to Work? | Provibol – Proviron Half Life

Proviron – Provibol is starting to work in a matter of minutes after the compound is used but it requires a while until you start seeing its effectiveness. Mesterolone is offering a half life of approximately 12 hours and the half life is the amount of time needed for half of amount of the steroid to be flushed out of the system. This means that Mesterolone is going to stay in the system for about 24 hours.

Despite the fact that this orally active steroid used as an aromatase inhibitor starts to work nearly immediately after its use, the compound requires a little while to build up in the system until the effectiveness starts to be noticed.

Provibol Usages | What Does Proviron Do? | What is Mesterolone Used For?

As it was mentioned, Provibol or Proviron containing Mesterolone are being used in medical settings as a prescription drug for multiple needs. Most often is given to men with low libido but it might have other uses too.

Nonetheless, the compound is still used in bodybuilding and it got popular years ago as an anti estrogen drug despite being an steroid, that’s because Provibol is having a high affinity to bind to the aromatase enzyme.

In the past, bodybuilders were using it as a form of Post Cycle Therapy (PCT) but nowadays this is rarely done because of the availability of much better options and chances that Proviron is suppressing Luteinizing Hormone (LH), but not in all situations.

Therefore, Provibol is used in bodybuilding as a part of “wet” steroid stack. Mesterolone is used alongside aromatizable steroids such as Dianabol, Equipoise (Boldenone), Testosterone, Nandrolone or any others.

With this steroid stack, the users ensures getting big by using the aromatizable steroid and is maintaining the water weight under control. Therefore, such a steroid stack would offer more vascularity, harder look and better definition overall.

Other than this, Proviron is strongly binding to SHBG – the hormone making steroids useless. By binding to SHBG, Proviron used alongside with other steroids is enhancing their effectiveness. This is the reason why Mesterolone is a better choice for many people than actual aromatase inhibitors.

How to Take Provibol? | Proviron Dosage | How Much Mesterolone Should I Take?

Provibol containing Mesterolone is an orally active steroid coming in form of tablets that should be taken by mouth on a daily basis because of the short half life of 12 hours. Most people prefer to use it 2 times a day, while once a day administration would still ensure stable blood levels.

In order to achieve perfect balance of big size and muscles as well as hardness and definition when stacked with other steroids, Provibol dosage is greatly depending on the dosage of the aromatizable steroid and logic says – the higher the dosage for the other steroid, the higher the dosage for Mesterolone.

As for female users – we do not recommend Proviron – Provibol at all because is too highly androgenic and barely any anabolic.

Despite being an orally active steroid, this compound is not C17 alpha alkylated so no liver issues should appear. That’s why you can take it for a cycle length as long as 8 weeks. Most used doses of Proviron are in the range of 25 mg up to 75 mg a day.

You can try 25 mg a day of Proviron and Dianabol for 6 weeks. Then you can increase to 50 mg each. Add supplements and a PCT protocol for avoiding negative side effects.

Provibol Side Effects | Proviron Side Effects | Mesterolone Side Effects

Being an anabolic steroid, is quite obvious that side effects are possible when talking about Mesterolone products. Pretty much as with any other steroids, side effects are dosage dependent which means that using too high dose of Proviron would obviously come with negative side effects.

Being a pure DHT derivative steroid, is quite obvious that androgenic side effects are to be expectable. Aggression, male pattern hair loss, acne, oily skin and others related can occur when using Provibol.

Other than this, you might get negative side effects on your cholesterol values as well as a negative effect on the cardiovascular system. Other than this, there might be other side effects not mentioned above.

However, remember that Proviron is by far not the worst in terms of side effects, at least for male users. The side effects intensity and frequency is greatly depending on many factors and dosage of the steroids, lifestyle choices, if there are any pre existent health issues and whether or not are you using cycle supporting supplements all play important roles.
