Proviron is one of the oldest anabolic androgenic steroids on the market. The production of pharmaceutical giant Schering first appeared in 1934. Officially known as Mesterolone, it has been sold under various brand names over the years, but the name Proviron has always prevailed. It is also one of the most misunderstood anabolic steroids among steroid users.

In many ways, Proviron is a very unique anabolic steroid. It has strong similarities to Masteron (Drostanolone) and Anavar (Oxandrolone) and Winstrol (Stanozolol) to some extent, but overall it is a unique animal. In terms of performance, Proviron is not used for weight loss, although it may play an important role in this stage of training. However, we will find that Proviron is much more used in hairstyles, but again the purpose will be quite unique.

As a drug, Proviron is one of the most common anabolic steroids in modern medicine. However, the hormone cholesterol has never been approved by the US FDA, it is found mostly in European medicine, especially in Western Europe. Its main purpose is to treat androgen deficiency because age is the most common cause of this condition. However, it is also used in pubic men. The hormone is also used as a fertility aid in men and this alone makes it an individual anabolic steroid because most anabolic steroids have the opposite effect.

Features and functions of Proviron:

Mesterolone is an anabolic androgenic steroid derived from dihydrotestosterone (DHT). More specifically, it is a structurally altered DHT hormone that replenishes the methyl group at the first carbon position. This allows the hormone to survive when taken orally and protects it from liver damage. It is one of the few oral anabolic steroids that is not C17-alpha alkylated (C17-aa), but contains an additional methyl group. Oral Primobolan is the second most popular oral steroid containing the same methyl group. Although the added methyl group protects it against degeneration, the overall bioavailability of Proviron is significantly less than that of most oral C17 steroids. Therefore, this has been detrimental to many performance-enhancing athletes, but as we shall see, this may not be justified.

Proviron has an androgenic rate of 30-40 and an anabolic rate of 100-150. All values ​​are based on testosterone, which is reduced by 100 in both categories and measured accordingly. Although its anabolic rate may be higher than that of testosterone, Proviron exhibits very little anabolic properties. This is very similar to Halotestin (Fluoxymesterone), which has a high anabolic rate but very low anabolic activity. In the case of Proviron, the hormone mesterolone, although highly anabolic in structure, is converted and metabolized into a diol metabolite, which in turn reduces anabolic activity. However, the androgenic evaluation of Proviron is a different matter. In fact, its convertible androgenic activity is generally higher than the build score indicates.

Based on performance, Proviron has four main properties that largely determine the mechanism of action. First, the hormone mesterolone has a high affinity for sex hormone binding globulin (SHBG). In fact, it is one of the most potent anabolic steroids in the world. By binding to SHBG, the hormone partially responsible for lowering free testosterone, binding to SHBG increases the amount of free testosterone in the blood. More importantly for an anabolic steroid user, they exhibit a higher percentage of anabolic steroids when used in the free state rather than the bound state. An easy way to do this is if the anabolic steroids you are taking have become stronger and more effective.

Proviron also has the ability to interact with the aromatase enzyme, the enzyme responsible for converting testosterone to estrogen. By binding to the aromatase enzyme, Proviron can effectively inhibit aromatase activity, protecting against estrogenic side effects. It will not have any anti-estrogenic effect close to the level of aromatase inhibitors (AI), but it will be noticeable. Depending on the type of cycle a person is in, Proviron may well cover all of their androgenic needs.

The hormone mesterolone also has a strong binding affinity for the androgen receptor. Again, this contributes to some extent to the functionality of other steroids and, more importantly, it promotes increased metabolic activity through direct lipolysis. So that leaves the last question about Proviron as a fertility drug. It is an anabolic steroid that does not inhibit gonadotropins like other anabolic steroids. It increases sperm production with minimal suppression and extremely strong androgenicity as androgens are needed to stimulate spermatogenesis. This not only increases the number of sperm cells produced, but also improves sperm quality significantly and just as significantly. Before we move on, let’s understand that Proviron has the ability to suppress gonadotropins, but there is a threshold that must be crossed for significant suppression to interfere with sperm production. This will make sense when we get to the side effect section.

Proviron effects:

Proviron will not be the main steroid in the enhancement phase and will not be the low season for most men. There are exceptions, and we will discuss them here. Proviron supplements can help a man recover from a shock during a cycle. At some point in each cycle, the progress begins to slow down, and in some cases it stops completely. By the way, Proviron improves the overall looseness of other steroids used in the tank, it can help some people overcome this stone damage. Out of season, most people use more testosterone. Many people also use large amounts during the cutting cycle, especially bodybuilders, but diets with low testosterone are more common in the cutting phase. But for various reasons, there are those who prefer to survive the low season on limited testosterone doses. In these plans, Proviron can provide the little androgenic support they need. Although not always necessary, it can be helpful.

The best time to use Proviron is undoubtedly the cutting phase. This steroid has the ability to provide a therapeutic effect similar to Masteron, but more importantly, it enhances the healing effect of other steroids. Next, let’s take a look at its strong binding to the androgen receptor, which actually allows a person to burn fat much more efficiently. From there, we must consider the anti-estrogenic effects of Proviron. This ensures that the person is less exposed to water retention and, as already mentioned, can manage without conventional anti-estrogens depending on the cycle. Therefore, we find ourselves with a sharp increase in free testosterone circulating. This can be very helpful since testosterone levels are often much lower at this stage of anabolic steroid use. In fact, with a low-dose testosterone cycle containing other anabolic steroids, we can safely say that the overall results will be better for someone who uses Proviron than someone who does not. Finally, the primary benefit of essential medications is the increased androgenicity of other steroids used to support a tighter, more precise physique. It should be noted that although Proviron can certainly provide these properties, they are only visible when you are thin.

Side effects of Proviron:

Possible side effects of using Proviron; However, this anabolic steroid has one of the highest levels of safety among all anabolic steroids. Most men can use this steroid without side effects, but despite the low probability, side effects are possible. For women, this steroid may not be recommended for therapeutic or potent purposes. The level of virilization is very high and should be avoided by women who want to protect their femininity. To help you understand the possible side effects of Proviron, we have divided them into separate categories with everything you need to know.

[1] Estrogen:

The hormone mesterolone is an estrogen. It has no flavor or progestin. As a result, Proviron side effects do not include related side effects such as gynecomastia or excessive water retention. Such side effects are not possible with this steroid. It also significantly reduces the risk of hypertension, as high blood pressure associated with anabolic steroid use is often a result of excessive water retention. In fact, Proviron is supposed to be an anti-estrogen, preventing or at least significantly reducing the conversion of testosterone to estrogen.

[2] Androgens:

The side effects of Proviron can be androgenic. This is not surprising as the main purpose of this steroid is androgenic activity. These Proviron side effects can include acne, accelerated hair loss in people prone to male pattern baldness, and hair growth. These effects largely depend on genetic disposition. For example, those who do not have the genetic predisposition to male pattern baldness do not lose their hair. People who are not acne prone should not have acne problems. It should also be noted that the hormone mesterolone is not metabolized by the 5-alpha reductase enzyme. Conversion to DHT does not occur, DHT is already present, so 5-alpha reductase inhibitors such as finasteride have little effect on the androgenicity of steroids.

Due to its strong androgenicity, Proviron causes severe virilization in women. This can and probably does include hair growth, deepening of the vocal cords, and clitoral enlargement. The use of this anabolic steroid is not recommended in women. There are several anabolic steroids that have a much lower virilization rate such as Anavar and Primobolan. These steroids should always be preferred by women.

[3] Cardiovascular system:

Cardiovascular stress, especially cholesterol issues, are the most dangerous side effects of Proviron. This anabolic steroid can negatively affect cholesterol to a much greater extent than most anabolic steroids. If you have high cholesterol, do not touch this steroid. If you are healthy enough to enjoy them, you should be very careful with your level.

The hormone mesterolone can significantly affect HDL and LDL cholesterol levels. Studies have shown that this steroid has the ability to reduce HDL cholesterol (good cholesterol) by over 30% and increase LDL cholesterol (bad cholesterol) by over 60%. Proviron is great to use without causing serious cholesterol problems, but it does require some effort. The most beneficial diet for cholesterol is important. It should be rich in omega fatty acids; You must eat a lot of fish oil every day. The human diet must also be very limited in saturated fats and sugars. It is also recommended to use a cholesterol-lowering antioxidant while taking Proviron. For some this is irritating, but you should include a lot of cardiovascular training in your program. If you are considering using this steroid, it is highly recommended that you follow these instructions. If for some reason you are unable to do so, you should not use this anabolic steroid.

[4] Testosterone:

All anabolic androgenic steroids naturally inhibit testosterone to some degree. The degree of suppression varies greatly from steroid to steroid and may be minimal when using Proviron. Studies have shown that using the hormone mesterolone is more than possible without significantly reducing natural testosterone production. That doesn’t mean it’s not removed, it just means it’s minimal and totally useless. A total dose of 150 mg or less per day should not significantly affect your natural testosterone production. When the total dose starts to increase above this point, the suppression rate also increases. However, increasing the dose to more than 150 mg per day does not benefit men.

Due to the minimal testosterone suppression, this anabolic steroid can be used without exogenous testosterone or at least in minimal amounts. A man can cycle Anavar with Proviron and prevent testosterone levels from dropping to very low levels. However, most people will use other anabolic steroids that significantly inhibit natural testosterone production with Proviron, making the use of exogenous testosterone crucial. Those who manage without it bring the body to a low testosterone level. This condition can be accompanied by a number of unpleasant symptoms and is extremely unhealthy.

Regardless of the specifications of the cycle, when all anabolic steroids disappear, natural testosterone production will resume. Most people at this stage are advised to implement a Post Cycle Therapy (PCT) plan. The PCT plan will speed up the recovery process; however, it will not return to normal by itself. It will take time to fully recover, but without a PCT plan it will take much longer. With a PCT plan, you ensure that you get enough testosterone to keep your body functioning while your levels naturally increase over time. It must be written; Natural recovery includes the absence of a previous low testosterone level. It is also believed that the hypothalamic-pituitary testicle (HPTA) axis is not severely damaged by overuse of anabolic steroids.

[5] Liver toxicity:

Although Proviron is an oral anabolic steroid, it is not toxic to the liver. It is not a C17-aa anabolic steroid and does not cause stress or damage to the liver.
