How does Proviron work?

The primary mechanism of action of Proviron is to inhibit aromatase, which is the process by which your body converts testosterone into estrogen. By inhibiting this conversion, Proviron helps to increase the amount of free testosterone in your body while simultaneously lowering estrogen levels. In addition to its effects on testosterone and estrogen levels, Proviron has also been shown to inhibit 5-alpha reductase, which is the enzyme responsible for converting testosterone into DHT.
The result of these three effects is that you will experience significant gains in muscle mass without experiencing any extra water retention or bloating. This makes Proviron a great choice for anyone who is looking to experience significant gains in lean muscle mass without having to worry about gyno or any of the other negative side effects that may be associated with other anabolic steroids.

What are the positive effects of taking Proviron?

As we talked about previously, there are several benefits of taking Proviron that make it such an attractive steroid supplement:

  • Increase in free testosterone levels: Since Proviron inhibits aromatase and 5-alpha reductase, it will increase the amount of “free” testosterone in your body because less total testosterone will be converted into estrogen or DHT. This means that you won’t experience any additional water retention, acne, or hair loss like you typically would with other anabolic steroids and you won’t experience any inhibition of your libido like you might with other DHT-derived steroids.
  • Boost in muscle mass: Proviron is not a steroid that causes water retention or high levels of estrogen like we already mentioned, but it does have the ability to significantly boost muscle mass due to the fact that it binds to the androgen receptor in muscle cells. This increases protein synthesis, which in turn helps to increase muscle mass.
  • Increase in strength: Just like with its ability to increase muscle mass, Proviron is also known for helping athletes improve their overall strength levels even without any significant water retention or bloating. Again, this is because of the fact that Proviron binds to the androgen receptor in a similar way that testosterone does. This helps athletes train harder and thus, gain more strength over time.
  • Increase in red blood cell count: Proviron has also been shown to increase levels of erythropoietin (EPO), which is a hormone that is released by your kidneys when they sense that your blood oxygen levels are low. This hormone is what stimulates the bone marrow to produce more red blood cells, which in turn increases your body’s ability to transport oxygen and help you recover from strenuous workouts.
  • Decrease in estrogen: Finally, one of the most well-known benefits of taking Proviron is its ability to significantly lower estrogen levels. This means that you won’t have to worry about experiencing any additional water retention, bloating, or gyno like you might with other anabolic steroids.

Mesterolone benefits for bodybuilding

We have discussed some of the benefits of mesterolone, and now it’s time to explain how these benefits could actually be particularly useful for people who are interested in maximizing their bodybuilding results.

Enhancing testosterone is one of the most important things for many bodybuilders. Testosterone is involved in a number of bodily functions that are important for helping to improve the results of your workouts.
Testosterone helps muscle growth. By enhancing testosterone levels, you are able to increase the rate of hypertrophy – that means that you’ll actually be able to stack on the pounds of muscle a lot quicker than you would be able to otherwise.
Testosterone boosts libido. This might not be immediately apparent as something that can help to boost your workouts, but libido is important. Libido equals sexual energy, and if you’re able to channel that sexual energy into a workout instead of chasing tail, you’ll be amazed at how much of a beast you can become.
Testosterone provides more motivation and energy, and it can be instrumental in helping you find the determination to actually hit the gym. Furthermore, once you’re there, you’ll be better able to hit the weights.

Muscle hardness and density are among the most desired results from working out. By increasing the amount of testosterone available to your body, mesterolone can help you maximize your muscle hardness and density.
This is a sure-fire way to help you improve your physique. Remember, though, that these benefits are most likely only going to be significant if you struggle with some sort of issue that prevents your body from producing testosterone.
That said, mesterolone can be useful in pre-contest training because it helps to provide an additional bonus to the hardness and density of your muscles. This is likely because it helps to reduce the amount of estrogen circulating in the body more so than an increase in the amount of testosterone.
Now it’s time for us to take a look at a few common benefits associated with Proviron usage.

These include the following:

Fat Loss

If you want to pack on 40 pounds of muscle in a single cycle, Proviron isn’t the steroid for you.
It promotes marginal increases in lean muscle tissue, but primarily it works by increasing core temperature, speeding up the metabolism, and helping to burn off stubborn body fat.
For those of you looking to get lean, either before a show, a holiday, or just because, Proviron is hugely beneficial, which makes it one of the top fat burning steroids.
Proviron is great for burning fat, leaving you looking leaner and slimmer than ever.

Great For Cutting

As many bodybuilders will know, the hardest part of any contest prep is the cutting.
During this phase of the prep, the bodybuilder’s primary objective is to burn off as much fat as possible, while maintaining lean muscle mass.
Proviron is a very useful steroid because it promotes lean muscle growth and enables the body to preserve what existing muscle it already has.
All of this is while the metabolism is ramped up burning off body fat, and you’re in a caloric deficit.

Inhibits Aromatization

One of the worst things about steroid use is the fact that many steroids promote a process known as aromatization.
This is a process where testosterone, either in the body or via the steroids themselves, is converted by the body into Estrogen.
Estrogen causes weight gain, water retention, hormonal fluctuations, gyno or gynecomastia, and much more besides.
It also promotes the production of cortisol, which is a stress hormone that is anti-anabolic.
Proviron however, does not aromatize.
In fact, it inhibits the aromatization process.
It is able to do this by interacting with the enzyme responsible for aromatization.
It binds to it and actually inhibits aromatization activity.
This means that it is able to offer much more protection against Estrogenic activity – helping you to avoid many of the side effects associated with it.

Increased Lean Muscle Mass

Okay, while it won’t pack anywhere near as much muscle onto your frame as Anadrol, Trenbolone, Dianabol, or other powerful steroids, this is still an androgenic anabolic compound that has the ability to promote increases in lean muscle mass.
If you use this steroid and continue to eat right, work hard in the gym, and lead a healthy lifestyle, you will notice improvements in your physique which will become more noticeable with each passing week.
On average, you can expect around 10 pounds of lean muscle from a cycle, which is certainly nothing to be sniffed at.
Building this amount of muscle naturally would take years, rather than months.

Improved Effects From Other Steroids

For best results, bodybuilders often stack Proviron with other anabolic androgenic steroids.
This is beneficial for two reasons.
The first benefit is the fact that it helps to prevent Estrogenic side effects as we mentioned previously.
The next benefit is the fact that Proviron actually acts as a catalyst for the other steroids in your stack, so it can make them more effective.
It does this because it carries a very strong binding affinity to the androgen receptors in your body.
This means that the Proviron, and the other steroids in your stack, become more effective.

No Injections

Not everybody likes sticking a needle in their skin, and if you’re one of those people that hate needles, you’ll love the fact that this is an oral steroid.
You can check more about this on our Oral Vs injectable steroids case study.
It is therefore taken in tablet form and is simply swallowed in the same way that you’d swallow a painkiller if you had a headache.

Who can benefit from taking Proviron?

If you are hoping to experience significant gains in lean muscle mass, stimulate natural testosterone production, increase libido, and reduce estrogen levels in your body, then Proviron may be a great choice for you. Although it is typically taken by men, women can also take Proviron to achieve the same effects.

Safety Recommendations

Regardless of your preferred cycle length, you should always take Proviron doses no more than once per day. More frequent administration can lead to significant increases in blood pressure levels and other adverse effects that are associated with taking higher amounts of this anabolic steroid.
In addition, individuals who use Proviron should only do so if they have been thoroughly educated about its effects on the body and how to maintain a safe dosage. Steroid abuse is never recommended under any circumstances, but with one of the least toxic compounds compared to most other forms of AAS, Proviron is one of the safest steroids to use.
However, it should be noted that individuals who are taking Proviron for any length of time should get their blood pressure levels checked regularly in order to ensure that their heart health is not at risk while they are supplementing with this anabolic steroid.
