What is Proviroxyl – Proviron (Mesterolone)?

Proviroxyl (Proviron – active substance Mesterolone) is representing one of the oldest anabolic androgenic steroids on the market as is one of the very first steroids that were ever discovered. This stuff is not the most powerful anabolic steroid on the market available, nonetheless, is still a very beneficial anabolic steroid that many bodybuilders got a lot of help using it.

Proviroxyl is indeed a very unique anabolic steroid which can greatly help those who understand how to use it properly. It is having pretty big similarities to Drostanolone Propionate,Stanozolol as well as Oxandrolone, however overall this stuff is still considered to be very unique, although has similarities to other steroids.

What is Mesterolone – Proviroxyl Used For?

Proviroxyl is not being used in order to promote some larger buildups in the mass as it won’t be as helpful as other steroids for this purpose, nonetheless, this stuff is by far more common in the cutting cycles during the time when the individual needs to lose body fat and preserve lean muscle tissue, even though is for somewhat unique purpose. Actually, the active substance in Proviroxyl is Mesterolone (but you might have heard about it as Proviron) and it has chemical names: 1 alpha-methyl-17 beta-hydroxy-5 alpha-androstan-3-one.

This substance is having an active life of up to 12 hours but the detection time is around 5 to 6 weeks. By purchasing oral Proviroxyl (Mesterolone) from Kalpa Pharmaceuticals, you can expect to get the contents of 30 x 25 mg tablets of this steroid. This steroid is great, so let’s check it all further to see why is considered so good.

What Mesterolone Does? | Proviroxyl (Mesterolone) Effects

This steroid is best used during the cutting phase compared to as if it would be used during the bulking phase of training. Although it can help with both these training cycles, the effects are much more helpful during the cutting phase. It is going to be very helpful for those individuals using it to make them burn body fat at a much more efficient rate. Those people using this steroid would burn off fat much faster and much more efficiently.

In addition to this, because of the anti estrogen effects that Proviroxyl possesses, the user of this product is going to be a lot much less prone to get some water retention and this is why, it has the potency to eliminate the need for a traditional anti estrogen that is very often being used by a lot of bodybuilders during their administration with many steroids.

Plus to everything, due to the enhancement of the circulating free testosterone, Proviroxyl is having some really amazing benefits when testosterone levels are low as it can greatly help. In fact, with a low dosed testosterone cycle that is including a lot of other anabolic steroids, the total results are going to be a lot much greater for that individual who is including Proviroxyl to their cycle, compared to the individual who is not going to include it.

Ultimately, the primary base benefit is the increased androgenicity of the other steroids that are being used in order to offer a much harder and a lot much more defined physique.

How Much Mesterolone You Should Take? | Proviroxyl (Mesterolone) Administration

In the performance capacity, it has been established that to get an anabolic effect of Proviroxyl and in the same time to keep it safe, this steroid dosage protocol is usually ranging anywhere between 50 to 150 mg per day. This level is tolerable by most people using it and in the same time is going to be great in offer amazing results.

Nonetheless, it was noticed that most men find out that the 100 mg per day is actually their minimal beneficial dose as they report getting much more out of 100 mg compared to 50 mg a day, however it is said that both 100 mg and 150 mg daily are being highly effective and there’s no need to use more than it. By taking higher doses, the individual is getting higher chances of getting side effects.

The total use is going to normally last anywhere between the 8 to 12 weeks. It is not recommended to get over this cycle length. This product is not recommended for women’s use because of its high virilization. There are other steroids that should be considered by females as they are much safer alternatives.

But men can find this product be extremely beneficial as Proviroxyl is stacking very well with a lot of anabolic steroids, in fact, it can be said that it stacks very well with all of them. By using this steroid during the cutting phase, is going to be the most beneficial when is being taken alongside with such steroids like for example: Oxandrolone, Primobolan, Stanozolol as well as Drostanolone Propionate. Proviroxyl is great during the cutting cycle, as is any of the steroids that were mentioned earlier.

By taking them together, the individual can get great effects because such stacks can greatly promote the androgenicity of those steroids in order to offer and promote the very desired hard look during the cutting phases of the athletes and steroids.

How Dangerous Is Mesterolone? | Proviroxyl (Mesterolone) Side Effects

Although this steroid is not recommended for women’s use because of the high virilization profile, Proviroxyl is still carrying one of the highest safety ratings among all of the anabolic steroids out there which means that is one of the safest steroid when compared to others. All of this indicates that most men are going to be able to use this steroid without getting any negative side effects, or very little and unnoticed, but still keep in mind that the side effects do indeed exist.

The Mesterolone hormone is not aromatized by the body and is also having no progestin nature, and therefore, the side effects like for example gynecomastia or excess of water retention should not occur while administering with this drug, in fact, they are impossible to occur. This makes the common use of an anti estrogen during the use of steroid administration be pointless. This is also going to greatly reduce the risk of getting high blood pressure, the type of high blood pressure that is being often associated with the anabolic steroid use. Since it offers no water retention, the blood pressure is having even lower chances to appear.

This steroid is androgenic steroid with no anabolic characteristics, however it does have androgenic side effects. The Proviroxyl androgenic side effects is including: acne, oily skin, body hair growth as well as accelerated/ worsening of hair loss in those men who are predisposed to male pattern baldness. Keep in mind that these effects are very highly dependent on the genetic predispositions.

Because of the very high virilization, as it was earlier mentioned, Proviroxyl is not recommended by female use, they should avoid it in order to avoid getting the masculinizing effects. Such effects are including body hair growth, clitoral enlargement, a deepening of the vocal chords, menstrual irregularities and others. The steroid has pretty high potency of offering such effects, that’s why women should opt for much safer alternatives like for example Primobolan and Oxandrolone. Those steroids are having a much lower virilization rating so they are considered to be much safer.

It is important to understand that Proviroxyl can also negative affect the cholesterol values pretty much as all other anabolic/ androgenic steroids, but the bad news is that Proviroxyl can affect it at a far more pronounced rate than most of the anabolic steroids. The use of steroids is generally not recommended to anyone who is having high cholesterol or any other cholesterol issues, but that’s especially true for Proviroxyl as you should avoid it by not worsening your cholesterol problems.

But even if you are a healthy enough individual to use Proviroxyl, you still should keep a close eye on your cholesterol levels and to have a cholesterol friendly diet. The steroid can greatly suppress / reduce the HDL cholesterol values (good cholesterol) and in the same time greatly increase the LDL cholesterol values (bad cholesterol). Make sure you keep a cholesterol friendly lifestyle including a healthy diet and active cardiovascular activity.

It is also important to keep in mind that all anabolic or androgenic steroids are suppressive to the natural testosterone at least at some level because different steroids do it at different rates. But in the end – they are all suppressive. This means that even though Mesterolone is not a hormone that is going to significantly reduce the natural testosterone production, is still going to do it at least to some extent. Because of the minimal testosterone suppression effects that it has, it is possible to use this anabolic steroid without the exogenous testosterone added to the plan, but generally doing so it is not recommended.

An individual using it can have a cycle of Oxandrolone taken alongside with Proviroxyl and to keep his testosterone levels from falling way too much in order to get a very low testosterone level. However, it very much depends on the genetics as well as the dosage used and that’s why adding at least some exogenous testosterone would be recommended.

In addition to this, most people are also going to include some other anabolic steroids that are very highly suppressive (at least much higher than Proviroxyl for example) to the natural testosterone production alongside with the Proviroxyl making the use of the exogenous testosterone be essential.

It doesn’t matter of the specifics of the cycle, as soon as all of the anabolic steroid use are going to come to an end and any trance of any steroids are going to get flushed out of your body – the natural testosterone production is going to start once again. But it is important to keep in mind the fact that the levels won’t return back overnight. The natural testosterone production is just going to start, it would require sometime until you would get the normal testosterone levels.

This is the main reason why most people who are using steroids suppressing the testosterone are strongly encouraged to add a Post Cycle Therapy (PCT) plan during that moment. This would make sure that the testosterone is going to restore faster and the user would get a safer/ better and faster recovery.

Although Proviroxyl is coming in form of tablets and is taken orally, the steroid is not C17 alpha alkylated which means that is not hepatotoxic. No hepatotoxicity means that the steroid is not going to cause any stress to the liver, therefore liver damage is impossible. However, make sure that you do check your liver in case you are taking Proviroxyl stacked with other steroids that might be C17 alpha alkylated and stressful to the liver.
