Dynabol (Nandrolone Cypionate)

(Nandrolone Cypionate)

Nandrolone Cypionate first appeared in the 1960’s around the same time as Nandrolone Decanoate, but would enjoy short-lived success on the human pharmaceutical market. Nandrolone Decanoate, best known by the trade name Deca Durabolin has largely dominated the human Nandrolone marketplace along with Durabolin (Nandrolone Phenylpropionate). However, while short lived on the human market Nandrolone Cypionate has enjoyed some success on the veterinarian market under the name Dynabol.

Dynabol first appeared though the veterinarian compounding group Jurox in Australia but would vanish from the market in 2001. In 2002, SYD Group in Australia would obtain all Jurox rights and reintroduce the Dynabol product, but this time under the name Anabolic DN and Anabolic NA. SYD group would also begin manufacturing a much stronger Nandrolone Cypionate, which it introduced to the Mexican veterinarian drug market. However, this venture was short lived as the U.S. DEA charged SYD Group with illegally exporting the compound from Mexico to the U.S. market for off label human use. Since that time the compound can only be found in Australia and under very tight control.

While no legitimate pharmaceutical, human or veterinarian Dynabol exists, at least no longer under that brand name, Nandrolone Cypionate can still be found. However, it is a very rare mixture of Nandrolone and largely not sought after as there is so much Nandrolone Decanoate and Nandrolone Phenylpropionate on the market. However, you will find some Underground Labs (UGL’s) that make it and regardless of the brand in question most all refer to all Nandrolone Cypionate as Dynabol.

For all intense purposes, Dynabol is identical to Deca Durabolin. The total Nandrolone traits will be the same, the possible side effects are identical and the end results should be a mirror. The only notable difference is the Cypionate ester is slightly smaller than the Decanoate ester, which will give Dynabol a slightly faster release time, but not by much. The difference in these two compounds on a functional basis is meaningless. The individual could use Dynabol or Deca Durabolin in a performance or therapeutic setting and receive the same results.

Dynabol Functions & Traits:

Dynabol represents an anabolic androgenic steroid comprised of the Nandrolone hormone. Nandrolone is a hormone that belongs to the 19-nortestosterone (19-nor) class, which infers that it is the testosterone hormone lacking a carbon atom at the 19th position. While this is a slight change to the testosterone hormone, it creates a very unique hormone in Nandrolone. Nandrolone is slightly more anabolic than testosterone carrying a rating of 125, but it is also far less androgenic carrying a rating of 37. With Dynabol, we then have the Nandrolone hormone attached to the rather large Cypionate ester, which is attached in order to control the hormone’s release time. Once in the bloodstream, the ester begins to detach and the hormone is released into the body. Due to its design, this will cause a sharp spike in Nandrolone the first 48 hours post injection followed by a slow continuous release of the hormone for approximately two weeks.

As a therapeutic agent, Nandrolone is one of the more beneficial anabolic steroids we have at our disposal. However, as Dynabol was only used in human medicine for a short time its use here may seem irrelevant. However, by understanding the Nandrolone hormone as a whole we can better understand Dynabol. The Nandrolone hormone has proven beneficial in the following treatment plans:

  • Osteoporosis
  • Advanced Breast Cancer
  • Lean Tissue Promotion pre and postoperative
  • Geriatric Weakness or Fatigue
  • Frailty
  • Burn Victims
  • Ulcers
  • Anemia
  • Growth & Development Retardation in Children
  • Pituitary Deficient Dwarfism
  • Preserving Lean Mass due to disease, i.e. AIDS, Cancer, etc.

Nandrolone has also been shown to hold an enormous amount of potential in therapeutic rejuvenation plans, and is sometimes prescribed by varying hormone replacement clinics. However, this practice is far more common outside the U.S. as the U.S. tends to be many years behind in anabolic steroid research compared to most of the world. This is largely due to strict government regulation that has prevented such research, but rejuvenation therapy with Nandrolone appears to be promising and when we examine the specific traits of Dynabol you’ll understand why.

Dynabol like all Nandrolone compounds carries several specific steroidal traits that largely define its total mode of action. They are not necessarily unique to the Nandrolone hormone, but there are two in particular that give this steroid an edge over many others. It will be these traits that also make Dynabol a very valuable commodity in performance enhancing circles, so much so that Nandrolone is one of the most sought after anabolic steroids by steroid users .The primary traits of Dynabol include:

[1] Enhanced Protein Synthesis:

Protein represents the primary building block of muscle. It is not the only necessary part of the equation, but it is imperative. Protein synthesis represents the rate by which cells build proteins, as this is enhanced, so is our ability to build and preserve lean tissue. Growth can now occur, recovery is improved and a better athlete developed. This will also greatly benefit any patient suffering from a muscle wasting disease or a geriatric patient.

[2] Enhanced Nitrogen Retention:

Nitrogen represents an integral part of lean muscle tissue; approximately 16% of all lean muscle mass is comprised of nitrogen. As nitrogen levels fall, this can lead to a catabolic (muscle wasting) state. Conversely, with enhanced nitrogen levels our anabolic atmosphere is enhanced. While this will prove beneficial to tissue building it will be imperative to lean tissue preservation and recovery.

[3] Increased Red Blood Cell Count:

Most all anabolic steroids increase red blood cell count to one degree or another. Red blood cells are responsible for carrying oxygen to and through the blood, and a higher count results in greater blood oxygenation. This will result in greater muscular endurance and also makes Dynabol a well-suited compound for treating anemia, a condition brought on due to a low red blood cell count. However, it is possible to increase red blood cells too much, but this would take an enormous amount of Dynabol for an extended period of time and is highly unlikely with responsible use baring any underlying issues.

[4] Enhanced Collagen Synthesis:

Collagen represents a protein in all connective tissues in the body but is most commonly associated with the connective tissue in the tendons, ligaments and cartilage as well as within the muscle tissue. The enhancement in synthesis should provide stronger connective tissue and recovery in the areas affected and will play an integral role with our next Dynabol trait.

[5] Enhanced Bone Mineral Content:

Bone Mineral Content (BMC) represents the density and strength of our bones. This enhancement through Nandrolone will provide stronger bones making it suitable for osteoporosis treatment. In fact, Nandrolone has proven to be one of the most effective combatants of osteoporosis on earth but due to U.S. regulations it has still not made it to such U.S. treatment plans in high capacity. When we consider the enhanced bone mineral content along with collagen synthesis, which can occur at high levels even with very low Nandrolone doses, this will provide tremendous therapeutic relief. Many athletes will use it solely for the joint pain relief it can provide, and it is true relief not a masking effect.

[6] Increased IGF-1 Output:

Insulin-Like Growth Factor-1 (IGF-1) should be enhanced to a degree due to Dynabol use, but it won’t be tremendous. However, any increase is beneficial due to IGF-1’s tremendously potent anabolic nature and positive effects on recovery.

[7] Inhibition of Glucocorticoids:

Glucocorticoid hormones, often referred to as stress hormones, destroy muscle tissue and promote fat gain. In many ways, they are the precise opposite of anabolic steroidal hormones. Some glucocorticoids are necessary to our wellbeing but only small amounts. Lowering total levels or inhibiting them from existing will result in a stronger metabolism and better physique. Therapeutically, this will prevent muscle tissue breakdown that often needs to be avoided or halted in such cases. This could also make Nandrolone a suitable hormone for those who have experienced prolonged exposure to corticoid hormones.

Effects of Dynabol:

By now we should be able to see the effects of Dynabol, but we want to look at things in a more realistic sense in order to give you an idea of what to expect. In this case, we will be strongly concentrating on performance enhancement but even through this concentration therapeutic benefits will be understood.

For the off-season athlete the effects of Dynabol will be tremendous. In fact, Nandrolone along with testosterone and the possible addition of Anadrol or Dianabol is one of the oldest most popular stacks of all time. The individual should be able to gain a lot of muscle mass, and while it won’t come fast it will be produced at a steady, even rate. Some do complain about water retention being problematic with Nandrolone and the hormone does aromatize; however, its rate of aromatization is only 20% that of testosterone. By controlling ones diet, which many fail to do in the off-season as well as using an anti-estrogen, water retention should not be an issue. The individual should also find he gains his new mass with less body fat accumulation that would otherwise occur due to the metabolic enhancement provided.

Very few think of Dynabol or any Nandrolone compound for that matter as a cutting steroid, at least very few gym rats and recreational steroid users. However, this can be a very common steroid in competitive bodybuilding circles during contest prep time, and odds are strong they will be leaner than you’ll ever be. Dynabol will provide significant protection to your lean mass. In order to lose body fat, you must burn more calories than you consume. This puts lean tissue at risk as the body will often take from muscle tissue to meet its energy demands. Even with a well-planned diet this will occur, but by enhancing the anabolic atmosphere with compounds like Dynabol this is minimized. Many also use Dynabol or related steroids during a diet for joint relief and overall recovery. Hard training alone is rough on the body, but when very lean it often becomes a little more intense.

Dynabol and perhaps more so other Nandrolone compounds are the most popular steroids in performance athletics. Nandrolone has for years been a primary steroid in professional football and has become essential to the game despite fan ignorance. This again goes back to the healing properties and pain relief provided. When we say pain relief, again we’re not talking about a masking effect such as through NSAID’s or opiates but rather true healing. Then consider the recovery promotion of connective tissue and muscle tissue overall and this steroid becomes invaluable. Further, due to the notable increase in red blood cell count muscular endurance is enhanced, the athlete doesn’t tire out as fast, and as a result, a better athlete now exist. Regardless of your reasons for use there is hardly an athlete or individual who cannot benefit from these effects of Dynabol.

Side Effects of Dynabol:

Dynabol, like all Nandrolone compounds, is a generally well-tolerated anabolic steroid for most adult men. In fact, an argument could be made that it carries a higher tolerable nature than testosterone due to its very low androgenicity. However, possible side effects of Dynabol most certainly exist, but when we understand the cause and effect it is very possible to avoid them. Total dosing will play a role, larger doses can increase the risk of adverse effects, but we must also take into account individual response. We are all unique in that we can display varying responses to varying hormones. Most healthy adult men will not have an issue with the side effects of Dynabol or related Nandrolone compounds when used responsibly. However, there will be some who even with what we label responsible use find issues arise. In order to help you understand the possible side effects of Dynabol, we have broken them down into their separate categories with all the information you’ll need.

  • Estrogenic: The possible side effects of Dynabol include those of an estrogenic nature. This is due in part to the Nandrolone hormone’s ability to aromatize. Aromatization refers to the conversion of testosterone to estrogen, and this can lead to gynecomastia and excess water retention when estrogen levels rise. However, the Nandrolone hormone only aromatizes at approximately 20% the rate of testosterone, but it also carries a strong progestin nature. Progesterone has the ability to promote estrogenic related effects, especially gynecomastia by stimulating the estrogenic mechanism in the mammary tissue. When Dynabol is used in conjunction with an aromatizing steroid like testosterone this increases the potential for such an effect.

    In order to combat the estrogenic side effects of Dynabol anti-estrogens are often recommended. There are two types of anti-estrogens that are useful in this regard, Selective Estrogen Receptor Modulators (SERM’s) like Nolvadex (Tamoxifen Citrate) and Aromatase Inhibitors (AI’s) like Arimidex (Anastrozole). SERM’s function by binding to the estrogen receptors, which in turn prevents the estrogen hormone from binding and becoming active. AI’s function by inhibiting the aromatase process, and as a result, lower serum estrogen levels. AI’s will be the most effective, and truly the only effective means in combating the progesterone activity. However, some men are not as sensitive to progesterone activity and will be able to get by with a SERM. Further, AI’s can have a negative impact on cholesterol where SERM’s cannot. In fact, SERM’s although anti-estrogens act as estrogen in the liver and can promote healthier cholesterol levels. SERM’s should be your first choice if they can get the job done.
  • Androgenic: The side effects of Dynabol despite its very mild androgenicity can include those of an androgenic nature. The androgenic side effects of Dynabol can include acne, accelerated hair loss in those predisposed to male pattern baldness and body hair growth.

    While androgenic side effects of Dynabol are possible, the likelihood of such effects is greatly diminished due to the Nandrolone hormone being metabolized by the 5-alpha reductase enzyme and reduced to dihydronandrolone (DHN). This is the same enzyme responsible for reducing testosterone to dihydrotestosterone (DHT) but DHN is far less androgenic in the target tissue of the skin and scalp. It is, however, very important to note that while metabolized by the 5-alpha reductase enzyme 5-alpha reductase inhibitors like Finasteride will actually interfere with the Nandrolone hormone and increase its androgenicity. The use of a 5-alpha reductase inhibitor with Nandrolone will increase the risk of androgenic effects. It is also extremely important to remember androgenic side effects are highly dependent on individual sensitivity, and as Nandrolone is moderate to weak in androgenicity such effects are unlikely in most men. This makes Dynabol and related Nandrolone compounds a preferred choice by many men who are sensitive to androgenic effects.

    Despite a low level of androgenic activity the side effects of Dynabol can include virilization in women. Virilization symptoms can include body hair growth, a deepening of the vocal chords and clitoral enlargement. Women can use low doses of Nandrolone, therapeutic doses in order to provide the needed relief, but performance use is not recommended. Women who desire performance based supplementation will find steroids with lower virilization ratings like Anavar (Oxandrolone) and Primobolan (Methenolone) to be better suited for performance based needs.
  • Cardiovascular: The side effects of Dynabol can include improper lipid levels and high blood pressure. High blood pressure is normally attributed to high levels of water retention, which can be controlled with an anti-estrogen and proper diet, in most cases. Cholesterol is a different story as Nandrolone will on average lead to a 25% reduction of HDL cholesterol, and this is without the use of an AI. The use of an AI may increase the adverse cholesterol action. This is a stronger, negative impact on cholesterol than testosterone can provide but typically much weaker than what can occur through the use of C17-alpha alkylated (C17-aa) anabolic steroids.

    Due to the potential negative effects of Dynabol on cholesterol, a healthy lifestyle is important. Cholesterol can be kept under control, but it will take some effort. The individual’s diet should be rich in omega fatty acids, which can easily be accomplished by daily fish oil supplementation. Saturated fats and simple sugars should also be avoided and plenty of cardiovascular training made part of your daily routine. Many may also find the use of a cholesterol antioxidant supplement to be very useful.
  • Testosterone: The side effects of Dynabol will include strong natural testosterone suppression in all men who supplement with therapeutic or supraphysiological doses. Data has shown that a mere 100mg of Nandrolone, a single injection is enough to completely suppress all natural testosterone production. Some studies have indicated that this low dose will not cause total suppression but at minimum a 75% reduction. In either case, this is enough to send any man into a low testosterone condition. A low testosterone condition can come with numerous bothersome symptoms, sexually related are the most common during the early stages, and it can also be extremely unhealthy.

    Due to the suppressive nature of Dynabol, all men who supplement with the hormone will need to include exogenous testosterone. The form of testosterone you choose is of no consequence, all that matters is you provide your body with enough of the hormone to meet its needs. If adequate amounts of testosterone are applied a low testosterone condition will not occur.

    Once the use of Dynabol has come to an end and all exogenous hormones have cleared the system natural testosterone production will begin again. However, recovering your prior levels will take some time; in fact, it can take several months. For this reason, most men are encouraged to implement a Post Cycle Therapy (PCT) plan once all steroid use has come to an end. Such a plan will greatly stimulate natural testosterone production and ensure a smoother recovery. It will not return your levels back to normal on its own; there is no PCT plan that can accomplish this. However, a solid PCT plan will ensure you have enough testosterone to meet your body’s needs, protect you from a cortisol buildup as well as protect your overall health as your levels continue to naturally rise.

    An important note on natural testosterone recovery – natural recovery assumes no prior low testosterone condition existed. It also assumes no severe damage was done to the Hypothalamic-Pituitary-Testicular-Axis (HPTA) due to improper supplementation practices.
  • Hepatotoxicity: Dynabol is not a hepatotoxic anabolic steroid and will present no damage or stress to the liver.

Dynabol Administration:

Therapeutic Dynabol dosing guidelines no longer exist as the steroid is strictly used in veterinarian medicine. However, if it were used in human medicine we can expect it would be similar to Deca Durabolin doses as the two compounds are so similarly related. This would place therapeutic Dynabol doses in the 50-100mg every 3-4 week range for approximately 12 weeks. However, in cases of anemia or severe muscle wasting the total dosing would fall in the 100-200mg per week range with 200mg per week being very common.

In a performance setting, in order to provide the therapeutic benefits along with strong joint and pain relief 100mg per week is generally considered the bottom dose. 200mg per week will provide the same benefit as well as a slight anabolic boost and far greater enhancements to muscular endurance. For the purpose of lean muscle gains, 300mg per week is standard with 400mg per week being far more common. Many men will, however, find they can tolerate 500-600mg per week very well, but this will increase the risk of adverse effects and is generally more Nandrolone than most need to meet their goals. Regardless of the dose, one injection per week will normally suffice. However, some may find two smaller equal injections per week to be more manageable and keep blood levels at their peak.

Regardless of the total Dynabol dose, in a performance setting 8 weeks is the minimum time frame of use to receive any benefit with 12 weeks being far more efficient. You will also find Dynabol stacks well with any and all anabolic steroids but will not benefit from the use of another Nandrolone compound.

Availability of Dynabol:

Dynabol is not in high supply and is generally only found on the Australian veterinarian market. You will not find Dynabol or any legitimate Nandrolone Cypionate compound on the U.S. pharmaceutical market. You will also find this steroid to be very rare on the black market. You will not find many if any internet steroid suppliers that carry the Dynabol brand and a generic Nandrolone Cypionate compound will also be extremely rare. However, if this is a steroid you desire simply using Nandrolone Decanoate will meet your needs. Nandrolone Decanoate is in high supply in all markets across the globe including the original Deca Durabolin brand manufactured by Organon.

Buy Dynabol Online - Warning:

You can buy Dynabol online from select steroid suppliers. Generally this will be very large suppliers who keep the steroid on hand for select customers. However, the ability to buy Dynabol online or at the pharmacy will be impossible for the vast majority. However, once again Nandrolone Decanoate and other Nandrolone compounds like Nandrolone Phenylpropionate can easily be purchased online, but this can come with several risks.

When you buy Dynabol or any Nandrolone compound online you will be doing so through a black market supplier. You can find very good deals on high quality products, but you can also waste a lot of money. You could be scammed out or your money, purchase a low or under-dosed product or worse yet one that is contaminated with bacteria. Then there’s the legal risk associated with such a purchase, and it is a big risk for those in the United States. In the U.S. anabolic androgenic steroids are classified as Schedule III controlled substances by way of the Steroid Control Acts of 1990 and 2004. Under this legislation the only way you can legally purchase and possess an anabolic steroid is with a prescription. Further, this prescription must be granted on the basis of medical need deemed justified by the U.S. government. Those who violate this law will be subject to heavy fines and prison time.

The steroid laws of the U.S. are very strict, but you will find they are far more lenient in numerous countries around the world. While most will not allow an online purchase many allow anabolic steroids to be purchased over the counter without a prescription for personal use. It is imperative you understand the law as it pertains to where you live before you make any anabolic steroid purchase.

Due to the strict steroid laws of the United States and a few other countries around the world, and due to the often unscrupulous nature of many steroid suppliers, you are encouraged to visit the sponsors here at The sponsors here at can provide you with high quality anabolics without a prescription or fear of legal risk.

Dynabol Reviews:

Dynabol is a high quality and generally well tolerated anabolic steroid. It’s not so much that Dynabol itself is a fantastic steroid but specifically the praise belongs to the Nandrolone hormone. In a therapeutic capacity the Nandrolone hormone may be one of the most valuable and beneficial hormones in existence. Unfortunately, especially in the U.S. the full benefits have yet to be appreciated due to the strict laws surrounding anabolic steroids, including the laws surrounding research itself. However, many physicians are beginning to understand the true benefits of the Nandrolone hormone, and in time it may very well become a more common hormone used in traditional medicine. Let’s hope so, for we know without question those who have been privy to such treatment have seen their lives transformed.

In a performance capacity, Dynabol as with all Nandrolone hormones is one of the best steroids you could ever choose. While numerous steroids have come and gone since Nandrolone was first synthesized it has remained atop the list of favorites for numerous athletes. Solid gains and ones that are easy to maintain are very common, and when we consider the healing and recovery benefits of this steroid it is virtually impossible to beat. Then we’re left with its extremely high threshold of toleration, and when looking for a quality steroid this puts Dynabol and Nandrolone in general far above most steroids.
