Overview and History of Omnadren

Omnadren, for all intents and purposes, is an almost identical twin to the Sustanon product. Both are oil-based injectable solutions of Testosterone that contain a mixture (or ‘blend’) of 4 different variants of esterified Testosterone in a particular concentration/ratio for each. Sustanon contains similar esterified variants of Testosterone that Omnadren does, but Omnadren typically contains the following:

Testosterone Propionate (30mg)
– Testosterone Phenylpropionate (60mg)
– Testosterone Isocaproate (60mg)
Testosterone Caproate (100mg)

Hence this is why Omnadren is often commonly compared to Sustanon, which contains all of the aforementioned Testosterone esters with the exception of Testosterone Caproate, which is simply replaced with Testosterone Decanoate (in Sustanon). The difference between Caproate and Decanoate is that the former is a shorter ester, and therefore a shorter acting variant of Testosterone that exhibits a shorter half-life. Unbeknownst to many athletes and bodybuilders, some of the very first Omnadren products actually contained Testosterone Isohexanoate and Testosterone Hexanoate listed as the last two variants in the mixture (instead of the last two listed above). However, these were not different Testosterone ester variants – they are just different names for the same final two variants (Isocaporate and Caporate).


Omnadren is a product of Polish origin developed by the pharmaceutical firm Polfa, and was developed during the Cold War under the Soviet Union’s iron curtain. The final ester being different from Sustanon is a decision that was made in order to circumvent any potential patent and legal issues among pharmaceutical corporations, Organon (the developers of Sustanon) and Polfa (the developers of Omnadren). The typical use for Testosterone and its different variants is for the treatment of androgen deficient males (hypogonadism or andropause), and Omnadren was initially very widely used for this purpose. This treatment was almost exclusive, with the only other known approved treatment being pubertal delay in adolescents, and to a much lesser extent, female breast cancer.

Polfa ceased manufacture of Omnadren in 1994, but after reorganization shortly after in that same year, Polfa inherited its new name, Jelfa. The primary reason for such a restructure and renaming was due to the fact that there were various other companies utilizing ‘Polfa’ in their name. So while Polfa ceased manufacture of Omnadren in 1994, Jelfa continued to manufacture it – essentially, there was no change to the situation except for a change in company name and logo. Omnadren is still manufactured today in Poland, and it is very common to see this product on other markets in the same region in many other countries in Eastern Europe and the Caucus region.

However, there is one surprising difference today: every single vial of Omnadren that is manufactured today actually contains the exact same blend of Testosterone estered variants as Sustanon. This means that Omnadren is basically just a clone of Sustanon today. All of the old preparations are nowhere to be found in the world today. This means that the current preparation of Omnadren as of this writing today (2013) contains the following Testosterone blend:

Testosterone Propionate (30mg)
– Testosterone Phenylpropionate (60mg)
– Testosterone Isocaproate (60mg)
– Testosterone Decanoate (100mg)

Chemical Characteristics of Omnadren

Omnadren, as previously mentioned is a precise blend of four different types of esterified Testosterone variants. Each of these Testosterone variants are molecules of Testosterone with esters chemically bonded to them at the 17th carbon position of the Testosterone structure. These esters used to be: Propionate, Phenylpropionate, Isocaproate, and Caproate under the old formulation. Today they are the following: Propionate, Phenylpropionate, Isocaproate, and Decanoate.

The addition of these esters slows down the rate of release of Testosterone into the bloodstream, which results in augmented half-lives of the different esterified forms of Testosterone. For example, Testosterone itself with no ester attached to it possesses a half-life of approximately 2 – 4 hours. When the Propionate ester is attached to it, for example, creating Testosterone Propionate, the half-life of Testosterone is now extended to 4.5 days, providing a slower release and activity of the hormone. Once in the body, enzymes work to cleave off and remove the attached ester from the Testosterone molecule, of which the end result is pure Testosterone free to do its job in the body. The process of enzymes removing the ester is what is responsible for the varying half-lives and release times of the different esterified variants.

Omnadren itself with all of its Testosterone variants as a whole is designed to provide an initial fast peak of blood plasma Testosterone levels in approximately 24 – 48 hours following administration. Following this process, blood plasma levels of Testosterone are to remain elevated for a 21 day period due to the longer esterified Testosterone variants in the mix[1]. The goal and the idea behind the development and marketing of Omnadren was to primarily treat Testosterone deficient men and with the unique release rates of Omnadren, this is almost exclusively what the product was designed, intended, and used for.

Omnadren Side Effects

Omradren causes the same sorts of side effects that other compounds of testosterone do. in general, adult males who are healthy do tolerate Omradren very well. While this anabolic steroid is made in a lab, it’s testosterone nonetheless and the body won’t recognize the difference between synthetic and natural testosterone. In therapeutic settings, for low testosterone treatment, side effects may occur, but the odds of them happening are fairly rare, since patients are gaining testosterone that they were lacking, rather than bringing up testosterone over normal levels.

With therapy for purposes of enhancing athletic performance, Omnadren side effects may be more noticeable. However, they are typically quite easy to control. In general, males tolerate higher-than-standard levels of testosterone pretty well. Also, there are smart steps to follow which help those who use Omnadren for performance purposes to minimize or avoid side effects. Now, let’s talk about possible side effects of Omradren…

1.) Estrogenic

This anabolic steroid is estrogenic in a moderate way. This is because it has the capacity to aromatize. Aromitization happens when testosterone is converted into estrogen. When estrogen levels go up, side effects may manifest. The key estrogenic symptom linked with usage of Omradren is gynecomastia (excess breast tissue growth in males). As well, water retention may be a problem. When water retention is present, blood pressure may become high.

To minimize or eliminate the estrogenic side effects of this anabolic steroid, many Omradren users take anti-estrogens. There are a couple of popular choices and they are SERMs (Selective Estrogen Receptor Modulators) and AIs (Aromatase Inhibitors). Some of the most well-known and trusted SERMs are Clomiphene Citrate (Clomid) and Tamoxifen Citrate (Nolvadex). Popular examples of Ais are Letrozole (Femara) and Anastrozole (Arimidex). Aromatase Inhibitors are usually the most effective choices as they inhibit the process of aromatization and also lower levels of serum estrogen. However, there is a downside with AIs. They may negatively impact cholesterol levels and this side effect may be exacerbated by usage of testosterone which is exogenous. To manage cholesterol is not impossible. It’s something to think about before embarking on therapy with Omnadren.

For a lot of males, SERMs offer protection against cholesterol side effects. How well SERMs protect men from cholesterol issues linked with Omradren really depends on their dosages of the anabolic steroid, along with the way that they react to the steroid. SERMs do tend to positively impact cholesterol levels. If it’s possible for you to achieve your goals with a SERM, rather than an AI, you may want to stick with a SERM. Try it first and see how things go.

A lot of men do need AIs. In particular, if men are taking doses of testosterone which are supra-physiological, they may require AIs. SERMs may not work as well.

2.) Androgenic

This anabolic steroid may also trigger side effects which are androgenic. Such side effects may include hair loss which is accelerated, acne skin conditions and growth of body hair. With the hair loss symptom, men generally need to be genetically prone to male pattern baldness in order to be affected. Such side effects may happen because the hormone, testosterone, reduces to DHT (dihydrotestosterone), as it interacts with the enzyme, 5-alpha reductase.

Side effects are largely contingent of predispositions which are genetic. Some men will be ok, but other may want to think about using Finasteride, which is an inhibitor of 5-alpha reductase. Using an inhibitor may not stop androgenic side effects completely. However, it should help quite a bit.

Women who utilize Omnadren may experience symptoms of virilization. This happens due to the androgenic properties of Omnadren. Examples of possible virilization symptoms include vocal chord deepening and enlargement of the clitoris. Women do require testosterone, as males do. However, they don’t need nearly as much. Some females do require therapy for low testosterone. When they do, Omnadren is not chosen for treatment. For performance purposes, most females find that other anabolic steroids provide good results without the same risk of side effects. Omraden does have a relatively high rating for virilization.

3.) Cardiovascular

We touched on the risk of cholesterol side effects earlier. Using Omradren may negatively impact cholesterol levels. In particular, it may suppress levels of HDL cholesterol. When utilized alongside an AI, this side effect may be more pronounced. With this in mind, we recommend embracing a lifestyle which is cholesterol-free while you injecting Omraden. To offset the cholesterol side effect of this exogenous testosterone, you should follow a diet which is healthy and which features plenty of Omega fatty acids. As well, you should get lots of exercise which is cardiovascular.

While it’s possible to experience negative side effects linked with Omraden while following a healthy lifestyle, chances are good that a healthy lifestyle will be enough to counteract these side effects. However, if you have underlying health issues, you may be at higher risk of this type of side effect.

4.) Testosterone Suppression

When a person utilizes a testosterone hormone of any type, such as Omandren, the steroid will suppress the natural production of testosterone. If a person is a low testosterone sufferer, this possible side effect won’t be concerning. This type of person isn’t making enough of the hormone anyway. For a person who does produce enough testosterone naturally, typical natural production of the hormone will occur again after treatment with Omnadren, as long as the person hasn’t used the steroid in very high doses over the long term.

Basically, when a person stops using an exogenous testosterone steroid, he or she will not be able to produce testosterone naturally afterwards, until the body recovers. This is why a lot of people choose to follow (PCT) Post Cycle Therapy which speeds up the pace of recovery. While PCT won’t get a person back to normal, it will reduce the amount of time which is needed in order to recover. As well, it will make it possible for the person to access sufficient testosterone for optimal bodily function, as natural testosterone production levels begin to rise.

5.) Hepatotoxicity

This steroid isn’t hepatotoxic. This means that it will not trigger strain or damage to a liver organ.

Omnadren Administeration and Uses

For therapeutic usage (to treat low testosterone), this anabolic steroid is typically prescribed in a dosage of two hundred and fifty milligrams for a single injection, every three to four weeks. For performance-enhancing purposes, dosing is higher and more frequent. When utilized in order to minimize the suppression of testosterone which is triggered by the usage of other types of steroids which are anabolic, two hundred and fifty milligrams of Omnadren every seven to ten days it a normal recommendation. In order to access genuine anabolic advantages, most males will inject five hundred milligrams a week, which is divided into a couple of doses, one of which is injected each week.

Seven hundred and fifty to one thousand milligrams per week of this steroid is a pretty common dosage for those who want performance benefits. These doses are high, though, and this means that the risk of adverse side effects go up! However, men may take steps to reduce the risk. In general, five hundred milligrams per week of Omradren is more than enough for most guys.

Irrespective of dosage, many males get benefits from dividing their doses into smaller doses which are injected every other day. This dosing setup and schedule assist them with keeping their blood levels stable and also ensures that they are able to stay at their peaks all of the time. Some men find that they experience fewer dips in testosterone when they follow this dosage setup and schedule. If they injected on a less-frequent schedule, they might experience dips in testosterone, as the Phenylpropionate esters and short/small Propionate in the steroid might cause these dips.

Buy Omnadren, Availability and Legality

This anabolic steroid is not available within the pharma market in the USA. Its availability within the pharma market is Europe is rather limited. It is available in UGLs (underground labs) which carry the steroid. Some UGLs may offer a testosterone blend which features the original, older form of Omradren. However, the original, legal version of Omradren hasn’t been available in any legal pharma markets for a long time.


Many people have to get genuine Omradren through Web-based suppliers. This is often a risk, as a lot of labs which market steroids online are not high-quality laboratories. It’s important to research a source carefully before ordering Omradren online. A lot of suppliers don’t carry this anabolic steroid. An alternative which is easier to find is Sustaron 250. If you order it, you’ll get a steroid with the same blend of testosterone.

It is simple to buy this steroid online. Most people aren’t able to find it in any other way. As well, it’s quite affordable when compared to other compounds of testosterone. While it’s usually more affordable than Sustanon 250, while more costly than testosterone of the single ester type (including Testosterone Cypionate, Testosterone Propionate or Testosterone Enanthiate), it’s not very expensive in general. If you do make the choice to purchase Omradren via the Web, you should be able to purchase as much of it as you like.

Bear in mind that you may be scammed. You may send money and receive nothing. You may receive a product which is under-dosed or one which is contaminated with germs. We’ve cant over-stress the importance of being careful before ordering. Do some research and learn all that you can about prospective suppliers.

Omradren is a Class III controlled substance in America, which means that you’ll be breaking the law if you order in online or buy it through a local steroid dealer. The Steroid Control Act, which came into being in 1990, along with the Steroid Control Act of 2004, put Omradren in the illegal category. If you’re busted for ordering this steroid, you may need to pay big fines or spend time in jail. Other countries have different penalties.

This is a great anabolic steroid. While it’s not better than other forms of testosterone, this four-ester combination does provide a range of advantages for therapeutic and performance purposes.
