(PROVIRON) MESTEROLONE

Overview

Proviron represents one of the oldest anabolic androgenic steroids on the market. A product of the giant pharmaceutical company Schering, it would first appear in 1934. Officially known as Mesterolone, it has appeared under numerous brand names over the years, but the Proviron name has continually remained dominant. It has also remained one of the most misunderstood anabolic steroids among steroid users.

In many ways, Proviron is a very unique anabolic steroid. It shares some strong similarities to Masteron (Drostanolone) and to a degree Anavar (Oxandrolone) and Winstrol (Stanozolol) but in totality it is its own unique animal. In a performance capacity, Proviron is not used to promote large buildups in mass, although it can serve an important purpose during such a phase of training. We will, however, find Proviron to be far more common in cutting cycles, but once again its purpose will be somewhat unique.

Benefits

Mesterolone is a dihydrotestosterone (DHT) derived anabolic androgenic steroid. Specifically it is a structurally altered DHT hormone possessing the addition of a methyl group at the carbon one position. This allows the hormone to survive oral ingestion by protecting it from hepatic breakdown. This is one of the only oral anabolic steroids that is not C17-alpha alkylated (C17-aa) but instead carries the added methyl group. Oral Primobolan is the other most well-known oral steroid that carries this same methyl group. While the added methyl group does in fact protect it from breakdown, the total bioavailability of Proviron will be far less than most all C17-aa oral steroids. For this reason it has fallen out of popularity among many performance enhancing athletes but as we will see perhaps unjustifiably so.

Proviron carries an androgenic rating of 30-40 and an anabolic rating of 100-150. All ratings derive from and are measured against testosterone, which carries a rating of 100 in both categories. Despite having an anabolic rating that is potentially greater than testosterone, Proviron will display very low anabolic traits. This is very similar to Halotestin (Fluoxymesterone), which carries a massive anabolic rating but very little translatable anabolic activity. In the case of Proviron, while structurally very anabolic, the Mesterolone hormone converts and reduces to Diol metabolites, in turn reducing anabolic activity. However, Proviron’s androgenic rating is a different story. In fact, its translatable androgenic activity appears to commonly be higher than its structural rating would imply.

 

Dosage

Note; dosage information is only for scientific reference purposes. SARMs Central, does not condone the human consumption or use of this substance outside of a controlled scientific environment (i.e. a lab).

Standard Proviron doses to treat androgen or male fertility will normally fall in the 50-75mg per day range. Normally the total dosing is split into 2-3 25mg doses per day. In androgen deficiency plans, the total dosing almost always starts at 75mg per day and slowly reduces to 25-50mg per day depending on patient need.

In a performance capacity, Proviron doses normally range from 50-150mg per day. Most men, however, will find 100mg per day to be the minimum beneficial dose with both 100mg and 150mg being highly effective. Total use will normally last between 8-12 weeks. However, in an effort to breakthrough a sticking point in a cycle, say towards the end of a cycle a 6 week course of Proviron may do the trick.

When you’re planning your Proviron use, you will find it stacks well with all anabolic steroids. During the cutting phase it will be most beneficial in conjunction with steroids like Anavar, Masteron and Winstrol as well as Primobolan. It will greatly promote the androgenicity of these steroids in order to provide and promote the hard look desired. In a bulking phase, while it will stack well with all anabolic steroids it’s hard to say if you’ll need it or not. Some will simply keep it on hand and include it when it proves to be possibly necessarily beneficial.
