What is Mesterolone? | What is Proviron?

Mesterolone is a Dihydrotestosterone (DHT) derivative compound that is very often sold as Proviron since this is the brand name for the active substance and chemical name Mesterolone. Nonetheless, this androgenic and barely anabolic steroid – Mesterolone, can be found as many other trade names either.

Mesterolone is the steroid that is basically increasing your dihydrotestosterone levels because although is an DHT derived compound that is synthetically made in laboratories, is the purest DHT steroid you can find out there.

Due to the fact that Mesterolone sold as Proviron is barely anabolic, is not a steroid used for increasing muscle mass.

Nonetheless, DHT is still playing a very important role in bodybuilding and in a healthy male individual. It responds for the formation of male genitals including many other needs such as being the main androgen in hair follicles and prostate.

DHT is being formed naturally, about 5% of testosterone is going through 5 alpha reduction to form the potent DHT androgen, but with Mesterolone – you increase the numbers artificially.

Proviron is a precursor to full Testosterone Replacement Therapy (TRT)

In bodybuilding, as it was mentioned, is not helpful for increasing muscle mass due to almost no anabolic activity. Instead, the compound got pretty popular as an anti estrogen compound because it has a high affinity to bind to the aromatase enzyme.

That’s why, anabolic steroid users are using Proviron – Mesterolone in their steroid cycles (mainly in bulking cycles when they use aromatizable “wet” steroids) as an Aromatase Inhibitor (AI) analogue.

In the past, Mesterolone was also used as a Post Cycle Therapy (PCT) drug, but studies have proven that it suppresses LH and therefore is not recommended to be used for such needs. After all, this is a steroid and although it may not cause a serious suppression, it still not recommended.

Why would you need Mesterolone – Proviron when you have actual aromatase inhibitors (AIs)? Mesterolone and AIs are used for dealing with estrogenic side effects and for offering a harder look, more defined muscles with more vascularity and less puffiness of muscles. So, Proviron and AIs are helpful when taken with a wet steroid.

Yet, Meterolone is offers the benefit of binding very well to SHBG (sex hormone binding globulin) – something that AIs do not offer. This is the hormone that makes other steroids less effective. When Mesterolone is used, other steroids effectiveness is getting enhanced and that’s while it gives the estrogenic protection. So you get a drier look, no side effects related to estrogen and better results when using other steroids.

That’s why there’s no point to use Mesterolone – Proviron alone.

This is an orally active steroid that should be taken by mouth, swallowing with enough water. How much of it you should take depends on the dosage of the aromatizable steroid – once again, for getting the perfect balance.

You can take it with oral steroids (because is not C17 alpha alkylated so it doesn’t affect your liver) or you could use it with injectable wet steroids. Proviron is usually taken for as much as the cycle goes, but using it for more than 8-10 weeks is not very recommended.

You could try:

6 weeks of 25 mg of Proviron – Mesterolone and 25 mg of Dianabol with supplements like Cardarine and N2Guard.

8 weeks of 50 mg of Proviron and Dianabol with supplements.

75 mg a day is maximum recommended for man while women should not use this steroid at all.
