Proviron Mesterolone Injectable Testosterone Anabolic Steroid Hormones For Bodybuilder 1424-00-6

 

 

Detailed Product Profile:

CAS:1424-00-6

Molecular Formula: C20H32O2

Molecular weight: 304.47

Assay: 99.5%

Appearance: White crystalline powder.

Usage: Can be used as pharmaceutical material, is often used as an antiestrogenic treatment and may be used by those who have had a poor reaction to testosterone treatments. The drug has shown to be beneficial in treating sexual dysfunction, impotency and low libido. Mesterolons binds to estrogen receptors, reducing their activity, which not only reduces estrogen production, but also encourages natural testosterone production in the body.

Description:

Proviron (mesterolone) is an interesting anabolic steroid, though it is not of much value to bodybuilding. It seems that the most common reason for many to consider including it in a steroid stack is for anti-estrogenic activity. In the days before anti-aromatases and the use of SERMs (selective estrogen receptor modulators) such as Clomid and Nolvadex, there was some merit to this.

 

An amount of aromatizing steroid marginally over the amount that would be tolerable without Proviron became tolerable with the inclusion of it. However, the effect is indeed only marginal, and much better anti-estrogenic agents now exist. When these are used, there is no need for Proviron as an anti-estrogen.

The mechanism by which it has some effectiveness in this regard is from binding weakly to the estrogen receptor without activating it, and to the aromatase enzyme.

 

In the first case, this partially reduces the number of receptor sites momentarily available to bind estrogen, thus reducing estrogenic activity. In the second case, some fraction of aromatase molecules at any given moment are unavailable to bind and convert testosterone, their binding sites being occupied with mesterolone.

 

What’s the difference between proviron and masteron:

The main difference between Proviron and Masteron is their relative level of anabolic activity in skeletal muscle. Both steroids are capable of attaching to and activating the androgen receptor in muscle tissue. As such, both are theoretically capable of supporting muscle growth. But there is one major problem with Proviron.

 

Like the base steroid dihydrotestosterone, Proviron has a high affinity for the 3-alpha hydroxysteroid dehydrogenase (3HSD) enzyme. Why is this important? It is important because 3HSD produces a weaker steroid by removing the highly important 3-keto group on the active steroid molecule. It this case it produces what are known as weak steroid “diols”. 3HSD is present in high amounts in muscle tissue, and represents a sort of blocking wall for the steroid to get through before it is able to find its corresponding receptor in the cytosol of the cell.

 

Proviron and DHT will be actively looking for 3HSD if you will, and as a result very little will find the receptor before being converted to weakly active steroids. This is why people do not gain a lot of muscle mass while taking DHT or Proviron. The 1-methlation may result in improving the oral bioavailability of Proviron, hence the fact that it is an oral drug, but it doesn’t do much to protect it from 3HSD.
