Steroid Profiles


(Testosterone Blend)

Omnadren is a four-part testosterone blend that is virtually identical to Sustanon 250. While the original mixture was slightly different, the current model is a perfect mirror. As a testosterone compound, Omnadren represents a truly versatile anabolic steroid. It holds strong therapeutic benefits and as testosterone is one of the most important steroidal hormones in performance enhancement.

Omnadren was developed by Polfa in Poland under Soviet Union rule. Under the Polfa label Omnadren was dosed at 250mg/ml in the following concentration:

  • 30mg Testosterone Propionate
  • 60mg Testosterone Phenylpropionate
  • 60mg Testosterone Isocaproate
  • 100mg Testosterone Caproate

This is the precise mixture of Organon’s Sustanon 250 with the exception of the final Caproate ester. Sustanon 250 contains the same first three testosterone esters in the same concentrations, with the final 100mg being comprised of Testosterone Decanoate. However, currently the Omnadren mixture has been changed by replacing the Caproate ester with the Decanoate ester making it identical to Sustanon 250. The Omnadren brand name is now also owned by Jelfa Pharmaceuticals. The Jelfa name simply replaced the original Polfa shortly after the fall of the Soviet Union. An important note, the original Omnadren mixture containing Testosterone Caproate is no longer available. Any supposed Omnadren with this ester listed will be a counterfeit.

Omnadren Functions & Traits:

Omnadren is a four-part testosterone blend that is designed in an effort to provide fast acting testosterone benefits with long lasting effects. The purpose of all testosterone blends is to provide exogenous testosterone therapy to patients in a way that limits the total injection schedule while simultaneously maintaining stable testosterone levels. By this mixture, the individual can easily treat a low testosterone condition with one injection every 3-4 weeks. This is quite an improvement over standard single ester testosterones, which will require 1 injection every 7-14 days.

For the performance athlete, Omnadren and other testosterone blends do not provide an advantage over single ester testosterone forms. While Omnadren contains four distinct testosterone forms, it is no more or less potent than any testosterone hormone. Further, the performance athlete will need to inject the hormone far more frequently in order to maintain not only stable levels but also peak levels of testosterone.

For the low testosterone patient, Omnadren is a perfect remedy. If you suffer from low testosterone, the only thing that will remedy the condition is testosterone. Low testosterone can be an extremely bothersome condition that comes with numerous possible symptoms. Such symptoms can affect your physical, mental and sexual well-being. Such a condition is not life threatening, but if ignored it can be a gateway to numerous conditions that can be life threatening indeed. If you suffer from low testosterone, common symptoms include:

  • Loss of Libido
  • Erectile Dysfunction
  • Increased Body Fat (despite diet & exercise)
  • Loss of Strength (despite diet & exercise)
  • Loss of Muscle Mass (despite diet & exercise)
  • Insomnia
  • Decreased Mental Clarity
  • Decreased Focus
  • Lethargy
  • Irritability
  • Depression
  • Weakened Immune System

If you suffer from any of these symptoms, you are encouraged to have your testosterone levels checked. However, if you live in the U.S. you will not be prescribed Omnadren. This testosterone blend is predominantly found in Eastern Europe. In the U.S. single ester testosterone compounds dominate the pharmaceutical market.

For the performance athlete, Omnadren will provide enhancements in every area that affects low testosterone treatment. However, in this case, it is the enhancement of direct effects brought on by high testosterone levels that are of interest. In a therapeutic setting we are merely attempting to return levels to a normal range. In a performance setting, we are attempting to take them above and beyond what could ever be achieved naturally. Through high testosterone levels, the following is provided:

  • Enhanced Protein Synthesis: This refers to the rate by-which cells build proteins, the building block of muscle tissue.
  • Enhanced Nitrogen Retention: All muscle tissue is comprised of approximately 16% nitrogen. The more we retain the more anabolic we remain. Conversely, a nitrogen deficiency will result in a catabolic (muscle wasting) state.
  • Increased Red Blood Cell Count: Red blood cells are responsible for carrying oxygen to and through the blood. Higher levels of blood oxygenation result in greater muscular endurance, as well as improved recovery.
  • Increased IGF-1 Output: Insulin-Like Growth Factor-1 (IGF-1) is a potent and naturally produced peptide hormone. It is highly anabolic, carries numerous traits that affect our bodies recovery and further affects nearly ever cell in the human body.
  • Inhibition of Glucocorticoid Hormones: Glucocorticoid hormones (stress hormones) are in many ways the precise opposite of anabolic steroids. They destroy muscle tissue, promote fat gain and can make improvements very difficult when they become dominant.

By increasing our testosterone levels, we create the perfect anabolic atmosphere for nearly all performance related goals. Through high levels, we further enhance our metabolic rate. High testosterone levels will not directly burn body fat, but they will promote a more efficient metabolism. This will be beneficial in both an off-season and cutting phase.

Effects of Omnadren:

For the individual who suffers from low testosterone the effects of Omnadren will result in the condition no longer existing. While that may sound simple that’s really all there is to it. Your testosterone levels were low, you injected Omnadren and they no longer are. Problem solved. For the performance athlete, as a remarkably versatile anabolic steroid, the effects of Omnadren can be beneficial in many ways. In the end, the total effects will be dependent on your diet and training, especially your diet.

For the off-season athlete looking for increases in lean muscle mass, Omnadren is one of the best choices he could ever make. High testosterone levels with adequate food intake will result in growth at an accelerated rate. Further, due to the metabolic enhancement provided, the individual will gain less body fat than he would otherwise. Make no mistake, you can still gain a lot of fat, but you can control and make better use of your calories when testosterone levels are high. The individual should also find his strength increases significantly.

Then we have the cutting phase and in some circles testosterone is often viewed as a poor cutting steroid. This thinking is due to the hormone’s ability to aromatize and promote excess water retention. However, as we will see later on water retention can be controlled. More importantly, the use of Omnadren during this phase will protect your hard earned muscle tissue during the diet. In order to lose body fat, you must burn more calories than you consume, and this will put lean muscle tissue at risk. High levels of testosterone will ensure you protect as much muscle mass as possible. High testosterone levels will also ensure you burn fat at a more efficient rate than you would with normal levels. When it comes to a cutting phase, losing body fat and protecting muscle mass are the primary goals, and Omnadren will ensure they are met.

Regardless of who you are or why you’re supplementing with this steroid, all who use Omnadren will find their rate of recovery is enhanced, as well as their muscular endurance. This makes Omnadren a fantastic steroid for performance athletes. They may not be looking to add a lot of size and they won’t if their calories are not at surplus levels, but the other benefits are invaluable. Couple this with the boost in strength and you have a perfect steroid for athletic enhancement.

Side Effects of Omnadren:

As a testosterone compound the side effects of Omnadren will be identical to all testosterone compounds. This makes Omnadren a very well-tolerated steroid for most healthy adult men. While synthetic in nature, it’s still testosterone and the human body will make no distinguishing difference between it and what you naturally produce. In a therapeutic setting to treat low testosterone, while side effects are possible the odds are highly in your favor. In such cases you are merely replacing what you’re lacking and nothing more. In a performance setting, this is where the side effects of Omnadren will be the most pronounced. However, they can still be controlled. Most men can tolerate high testosterone levels fairly well, especially if they take the correct steps. In order to understand the side effects of Omnadren, we have broken them down into their respective categories along with all you need to know.

[1] Estrogenic:

Omnadren is moderately estrogenic due to its ability to aromatize. Aromatization refers to the conversion of testosterone to estrogen, and as estrogen levels rise this can lead to side effects. The primary estrogenic side effects of Omnadren are gynecomastia and excess water retention. Water retention can also promote high blood pressure if it gets out of hand.

In order to combat the estrogenic side effects of Omnadren, anti-estrogens are often recommended. You have two choices in anti-estrogenic medications for this purpose, Selective Estrogen Receptor Modulators (SERM’s) or Aromatase Inhibitors (AI’s). Common SERM’s include Nolvadex (Tamoxifen Citrate) and Clomid (Clomiphene Citrate). Common AI’s include Arimidex (Anastrozole) and Femara (Letrozole). AI’s will be the most effective as they inhibit the aromatase process and lower serum estrogen levels. Unfortunately, they can also have a negative impact on cholesterol, which can be exasperated by the use of exogenous testosterone. Cholesterol management is possible but must be taken into consideration. For many men, depending on the dose and individual sensitivity to estrogenic side effects, SERM’s will provide the protection they need. As a bonus, they appear to have a positive impact on cholesterol. If you can get the job done with a SERM this should be your first choice, but many men, especially with supraphysiological doses of testosterone will need an AI.

[2] Androgenic:

Omnadren carries with it several possible androgenic side effects. Such effects include acne, accelerated hair loss in those predisposed to male pattern baldness and body hair growth. These effects are due to the testosterone hormone’s reduction to dihydrotestosterone (DHT) due to its interaction with the 5-alpha reductase enzyme. Such effects are highly dependent on genetic predispositions, many men will be fine but some may consider the use of a 5-alpha reductase inhibitor like Finasteride. The use of an inhibitor will not completely reduce the androgenicity of the hormone, but it will make a notable difference.

The androgenic nature of Omnadren can also lead to virilization symptoms in women. Such symptoms include body hair growth, a deepening of the vocal chords and clitoral enlargement. Women need testosterone just as men; however, they need far less. There are women who need testosterone therapy, but Omnadren is not a form that’s recommended. In a performance capacity, most all women will find other steroids to be their best options. There are steroids that carry a much lower virilization rating and should be the first choice of any female athlete.

[3] Cardiovascular:

The use of Omnadren can have a negative effect on cholesterol. The noted effect will most commonly result in HDL cholesterol suppression. This can be more pronounced with the use of an AI. For this reason, a cholesterol friendly lifestyle is very important when using exogenous testosterone. A healthy lifestyle should include a healthy, cholesterol friendly diet, one that is rich in omega fatty acids and should include plenty of cardiovascular activity. While adverse cholesterol affects are possible, most men will be fine if they live a healthy lifestyle and no underlying issues exist.

[4] Testosterone:

The use of Omnadren or any testosterone hormone will suppress natural testosterone production. For the low testosterone patient this is of very little concern. Such an individual is no longer producing enough testosterone to begin with. For the individual who still produces adequate amounts of testosterone, assuming he does not supplement with reckless abandonment will find his natural production begins again once all exogenous steroidal use has come to an end.

Due to the suppression, once all steroid use has come to an end implementing a Post Cycle Therapy (PCT) plan is commonly recommended. This will speed up the rate of recovery. It will not return you to normal on its own, but it will greatly cut down on the time frame of recovery. It will also ensure you have enough testosterone for proper bodily function while your levels continue to naturally rise.

[5] Hepatotoxicity:

Omnadren does not carry a hepatotoxic nature and will present no stress or damage to the liver.

Omnadren Administration:

In a therapeutic setting, Omnadren is normally prescribed at 250mg in one single injection every 3-4 weeks. For the performance athlete, the dosing and injection frequency will be greatly enhanced. To combat testosterone suppression caused by the use of other anabolic steroids, 250mg every 7-10 days is normally recommended. For true anabolic benefits most men will find 500mg per week split into two 250mg doses per week to be beneficial and well within the realm of control. 750-1,000mg per week of Omnadren is not uncommon. Such doses will greatly increase the probability of adverse side effects but should still be very controllable for many men. However, most men will not need more than 500mg per week.

Regardless of the dose, many men find splitting their dose into smaller every other day injections to be very beneficial. This will not only maintain stable blood levels but it will ensure they are at their peak at all times. Many feel they have less dips in testosterone levels that would otherwise occur with less frequent injections due to the small/short Propionate and Phenylpropionate esters that in part make up Omnadren.

Availability of Omnadren:

Omnadren is not available on the U.S. pharmaceutical market and is very limited on the European pharmaceutical market. There are several underground labs that carry the compound, and some may even carry a testosterone blend comprised of the original mixture, but the original Omnadren mixture of Omnadren has not been available on any legitimate pharmaceutical market in a long time.

For most, the only way to obtain true Omnadren will be through a large internet based supplier. However, this can be risky as many of the labs found online are anything but quality labs. Researching your source will be imperative. If you’re supplier does not carry Omnadren, and many won’t, remember you can always buy Sustanon 250 and you will be receiving an identical testosterone compound. Most all suppliers carry Sustanon 250.

Buy Omnadren Online - Warning:

You can easily buy Omnadren online; in fact, it’s the only way most of you will ever be able to find it. You will also find that it’s a fairly affordable testosterone compound. It’s generally a little cheaper than Sustanon 250 but normally a little more expensive than single ester testosterone like Testosterone Cypionate, Testosterone Enanthate or Testosterone Propionate. If you decide to buy Omnadren online, another bonus is you’ll be able to buy all you want, but there are a few concerns when making an online purchase.

Anytime you buy Omnadren online or any anabolic steroid there’s always the risk of being scammed. You send your money but receive nothing in return. There’s also the risk of purchasing an under-dosed product or worse yet one that’s contaminated with bacteria. For these reasons, being patient and researching your supplier and the lab in question is beyond imperative. If you do these things, you will be able to find a quality supplier, but there’s an even bigger risk you need to be aware of. If you buy Omnadren online and you live in the United States you will be breaking the law. In the U.S. anabolic androgenic steroids are classified as Schedule III controlled substances by way of the Steroid Control Act of 1990 and the Steroid Control Act of 2004. Those who are caught violating this law risk severe punishments that can include heavy fines and jail time. The legality surrounding anabolic steroids can, however, vary greatly depending on the country in question. Some are similarly strict as the U.S. while others are far more lenient. However, most all countries will frown on online purchases.

Due to the risk associated with buying anabolic steroids, if you are looking for high quality anabolics you are encouraged to visit the sponsors here at The sponsors here at carry high quality and clean anabolics. Equally important you will not need a prescription and you can buy them without the risk of legal consequences.

Omnadren Reviews:

Omnadren is a fantastic anabolic steroid; in this there can be no doubt. However, it is in no shape or form superior over other testosterone forms. The four ester blend does not present a more powerful testosterone compound, you will not receive better results just because you’re using Omnadren over a single ester testosterone compound. The mixture itself simply presents an advantage for therapeutic patients but presents no advantage or disadvantage to performance enhancing athletes. If this is an anabolic steroid you’d like to use, you can easily find a good deal if you do a little digging.
