2.Product Description:
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.
As a therapeutic agent, Proviron is one of the most commonly used anabolic steroids in modern medicine. However, the Mesterolone hormone has never been approved by the U.S. FDA. It will primarily be found in European medicine, especially in Western Europe. The primary purpose of use is treating androgen deficiencies, age being the most common culprit of the condition. It is, however, also used in pre-pubescent males as well. The hormone is also used as a fertility aid in men and this alone makes it a very unique anabolic steroid as most anabolic steroids tend to have the opposite effect.
3.Product Functions:
Mesterolone is a dihydrotestosterone 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.
On a functional basis, Proviron carries four primary traits that largely define its mode of action. First and foremost the Mesterolone hormone has a strong binding affinity to Sex-Hormone-Binding-Globulin (SHBG). In fact, it appears to be one of the strongest anabolic steroids in this regard. By binding to SHBG, a hormone partially responsible for reducing free testosterone, binding SHBG will enhance the amount of circulating free testosterone. More importantly for the anabolic steroid user, it will make a larger percentage of the anabolic steroids used available in a free rather than bound state. A simple way to look at it is the anabolic steroids you’re taking become more powerful and potent.
