Dynabolon is a once popular anabolic steroid comprised of the active steroidal hormone Nandrolone attached to the very large Undecanoate ester. Very similar to Nandrolone Decanoate (Deca Durabolin), Dynabolon’s Undecanoate ester is slightly larger providing an even longer lasting therapeutic window. However, while once a popular steroid in therapeutic treatment plans and among performance enhancing athletes, Dynabolon is no longer on the market. In fact, there are no pharmaceutical brands of Nandrolone Undecanoate currently produced, and it is also rare on the black market.
Dynabolon first appeared in the early 1960’s and enjoyed relatively strong success throughout much of Europe. The compound was also sold as Psychobolan in some markets, but Dynabolon remained the dominant brand. This anabolic steroid proved to hold numerous therapeutic benefits and was approved for the use in the treatment of osteoporosis, malnutrition and any general catabolic conditions. However, despite a very decent track record of safety, in the 1990’s Dynabolon and all Nandrolone Undecanoate compounds would slowly disappear from the market.
Dynabolon was also a somewhat popular anabolic steroid among performance enhancing athletes during its more than thirty years of existence. However, while every bit as effective as Nandrolone Decanoate, it never gained a mass following due to the Decanoate version being so readily available. In some markets, while available in much of Europe, Dynabolon was hard to find leaving many performance enhancing athletes always choosing Nandrolone Decanoate or the faster acting Nandrolone compound in Nandrolone Phenylpropionate (Durabolin or NPP). Regardless, this was an excellent steroid for off-season mass gains and general athletic enhancement, but while no longer existing the individual can still receive the same benefits of Dynabolon with other existing Nandrolone forms.
Dynabolon Functions & Traits:
Dynabolon is an anabolic androgenic steroid comprised of the 19-nortestosterone (19-nor) hormone Nandrolone. The 19-nor classification notes a structural change to the testosterone hormone in that it lacks a carbon atom at the 19th position. Dynabolon is also a Nandrolone hormone attached to the very large Undecanoate ester; in fact, it is the Undecanoate ester that defines Dynabolon. The Undecanoate ester is one carbon atom larger than the Decanoate ester, and as a result, provides a longer active Nandrolone window.
As a Nandrolone hormone, Dynabolon carries an anabolic rating of 125 and an androgenic rating of 37. While it’s anabolic rating is only slightly higher than testosterone, its reduced androgenicity is welcomed by many who are sensitive to androgenic side effects. Dynabolon is also a very moderately estrogenic hormone in that it does aromatize. However, its rate of aromatization is only 20% that of testosterone, but it’s also a progestin and this will calculate into its total estrogenic activity.
On a functional basis, Dynabolon is a very basic anabolic steroid. It does not possess traits that we can call unique to this Nandrolone form. However, it possess some basic steroid traits at varying levels of power that can prove very useful when combined with the right cycle, diet and training program. The functions and traits that represent Dynabolon and largely provide its therapeutic and performance benefits include:
 Enhanced Collagen Synthesis:
Collagen plays an important role on the strength of tendons and ligaments, as well as an important role in cartilage and bone density. It is also plays an integral role on the connective tissue within the muscle tissue of the human body. Collagen is a naturally produced protein and the primary protein of all connective tissue. With an enhanced rate of synthesis, there is simply more available to do what it does best. This will play an important role on recovery and rejuvenation along with enhanced bone mineral content, and is precisely why Dynabolon is so valuable to many athletes.
 Enhanced Bone Mineral Content:
When bone mineral content is low, this causes the individual to be more susceptible to osteoporosis and bone fractures. Conversely, enhanced bone mineral content will strengthen the skeletal structure. In fact, in conjunction with collagen synthesis, Dynabolon along with other Nandrolone hormones could very well be a perfect solution for many who suffer from osteoporosis.
 Increased IGF-1 Production:
IGF-1 (Insulin-Like Growth Factor-1) is a naturally produced hormone of immense anabolic power. It is also essential to our body’s recovery abilities, and affects nearly every cell in the human body. With higher levels of IGF-1, there is simply more available for the body to work with.
 Increased Red Blood Cell Count:
Red blood cells can provide the benefit of greater muscular endurance when the total count is increased. This is due to the cells being responsible for carrying oxygen to and through the blood. This will also play an important role on the recovery process, as well as the individual’s total anabolic atmosphere.
 Decreased Glucocorticoid Production:
Glucocorticoid hormones, cortisol being the most well-known, are commonly referred to as stress hormones. While essential to our health in small amounts, they also have the ability to destroy muscle tissue and promote body fat gain. Glucocorticoid hormones are in essence the opposite of anabolic steroids.
 Enhanced Protein Synthesis:
Protein synthesis represents the rate by which cells build proteins, the primary building block of lean muscle tissue. When synthesis is increased, protein is used more efficiently, the body is primed for anabolic action, more tissue is built and preservation of lean tissue enhanced.
 Enhanced Nitrogen Retention:
When nitrogen levels fall, this can lead to a catabolic (muscle wasting) state. This is due to all lean muscle tissue being comprised of approximately 16% nitrogen. When nitrogen retention is enhanced, this ensures the anabolic atmosphere is maintained, and is essential to the preservation of lean muscle tissue.
Effects of Dynabolon:
The effects of Dynabolon on anabolism primarily cause this steroid to be viewed as an off-season bulking agent and nothing more. Without question, this is one of the best bulking steroids on earth, but its benefits towards athletic enhancement may be the most beneficial of all. Nandrolone hormones are very popular among many athletes, including those who have no desire for any pronounced lean tissue growth. This is due to the effect of Dynabolon and other Nandrolone hormones being one of the best for promoting increases in muscular endurance and recovery; recovery is where it truly shines. Due to the effects of Dynabolon, you will not tire out as fast; your muscles will be able to work at their peak performance for longer periods of time under stress. Then we have healing, and hard training and performance can cause the body to take a beating. When we heal faster, and in this case we’re talking about true healing, we can perform at a higher level more frequently. Further, when it comes to healing this is where actual progress is made. Progress isn’t actually made when we train. Training actually tears down the muscle tissue, but healing is what makes it stronger and what makes it grow. Regardless of your purpose of use, the effects of Dynabolon on muscular endurance and recovery will be enjoyed by all who supplement with this anabolic steroid.
While beneficial to performance in a general sense as described, no one can deny the effects of Dynabolon in regards to lean tissue growth are anything but phenomenal. This steroid will not promote rapid weight gain, but with adequate calories it will promote significant gains in lean muscle mass. Some of the weight may be water weight, but this can be controlled through proper use. More on this when we look at the side effects of Dynabolon. As a great mass promoter, the effects of Dynabolon in this regard should be easier to hold onto compared to many anabolic steroids once use is discontinued. The individual should also find he gains less body fat during his off-season use due to an enhanced metabolic rate. This does not mean you won’t gain fat during your off-season, growth still requires excess calories, but you should be able to make better use of your nutrients consumed.
The effects of Dynabolon can also be beneficial during a cutting cycle. This is hard for many to wrap their head around as the steroid will not promote strong conditioning effects like Trenbolone or Winstrol. However, it is an excellent lean tissue preserver, and as lean tissue is always at risk when in a calorie deficit, which is necessary for fat loss, this can make Nandrolone beneficial. Due to the enhanced endurance provided by the effects of Dynabolon, the individual should be able to maintain more stamina during what is often an energy draining phase of training. The aspect of recovery will also be tremendously beneficial as recovery often becomes a little more difficult during a calorie deficit.
Side Effects of Dynabolon:
Possible side effects of Dynabolon do exist, but this is one of the most well-tolerated anabolic steroids of all time. While side effects of Dynabolon are possible, most men will find the threshold is very high. In fact, most healthy adult men can supplement with this or any Nandrolone steroid side effect free if they take the proper measures and thoroughly understand the hormone. In order to help you understand the possible side effects of Dynabol, we have broken them down into their separate categories along with all the information you’ll need.
The side effects of Dynabolon can include those of an estrogenic nature due to the hormone aromatizing. Aromatization refers to the conversion of testosterone to estrogen, and as estrogen levels rise this can promote water retention and gynecomastia. As a secondary action, excess water retention can also promote high blood pressure when it becomes severe.
While estrogenic, the Nandrolone hormone is only mildly estrogenic aromatizing at only 20% the rate of testosterone. However, this is enough to promote pronounced estrogenic activity, and it is also a progestin. Progesterone can increase the risk of gynecomastia due to it having the ability to stimulate the estrogenic mechanism in the mammary tissue, especially in sensitive men.
Due to the possible estrogenic side effects of Dynabolon, most men are encouraged to include an anti-estrogen with their Nandrolone use. There are two classes of anti-estrogens, Selective Estrogen Receptor Modulators (SERM’s) like Clomiphene Citrate (Clomid) and Aromatase Inhibitors (AI’s) like Letrozole (Femara). SERM’s function by binding to the estrogen receptor, and as a result, prevents the estrogen hormone from binding. AI’s function by inhibiting the aromatase process, and as a result, lower serum estrogen levels. AI’s will be the most effective. Unfortunately, when aromatizing steroids are conjoined with their use, this can have a negative impact on cholesterol. SERM’s are not as effective, but they can be enough for some men. Further, SERM’s will actually have a positive impact on cholesterol due to their estrogenic like action in the liver.
The possible side effects of Dynabolon can include those of an androgenic nature. However, such effects are highly unlikely in most men as the androgenicity of this steroid is tremendously mild. Such effects are highly dependent on genetic predispositions and include accelerated hair loss in those predisposed to male pattern baldness, acne in sensitive individuals and body hair growth.
Due to the possible yet unlikely androgenic side effects of Dynabolon, some may be tempted to use a 5-alpha reductase inhibitor in order to reduce the hormone’s androgenicity. However, this is not advised. 5-alpha reductase inhibitors like Finasteride are sometimes used to reduce the androgenicity of testosterone due to it being metabolized by the 5-alpha reductase enzyme and thereby reduced to dihydrotestosterone (DHT). Nandrolone is also metabolized by the 5-alpha reductase enzyme, but it is reduced to dihydronandrolone (DHN) not DHT and the use of an inhibitor will actually increase the hormone’s androgenicity.
The androgenic side effects of Dynabolon can also include virilization symptoms in women. Such symptoms can include a deepening of the vocal chords, clitoral enlargement and body hair growth. While only mildly androgenic, the translating androgenic activity appears to be higher in women than its structural rating implies. Some women can use this steroid without virilization symptoms if the dose is kept low and use is short-term. However, most women will find faster acting Nandrolone compounds like Nandrolone Phenylpropionate to be far more tolerable and manageable. Further, if virilization symptoms begin to show, the Phenylpropionate version can be discontinued and the symptoms will fade away if use is discontinued at their onset. If symptoms are shown and use is continued with any form, the effects may be irreversible. It will also take a lot of time for Dynabolon to clear the body due to its long acting nature making it a very poor choice in Nandrolone for women. Female use is not advised.
The side effects of Dynabolon can include high blood pressure, but if water retention is controlled and there are no underlying health issues, most men should not have a problem. However, the side effects of Dynabolon can also include improper lipid profiles. Cholesterol can be an issue, and the Nandrolone hormone can have a slightly stronger impact than testosterone. It should not have a strong statistical impact on LDL cholesterol, but it can significantly reduce HDL cholesterol levels. This can in turn skew the total lipid reading as HDL cholesterol is largely responsible for the regulation of LDL cholesterol.
Due to the possible cholesterol issues surrounding Dynabolon, a healthy lifestyle is imperative. If you have healthy cholesterol and live a lifestyle that promotes its continuation, bearing no underlying health issues, lipids should remain stable. In order to achieve this, a healthy cholesterol friendly diet is the first step. Saturated fats and simple sugars should be limited and omega fatty acids should be made an integral part of your diet. Daily fish oil supplementation will prove very useful. The individual should also ensure he implements plenty of cardiovascular activity into his routine.
The side effects of Dynabolon will include natural testosterone suppression in all men who supplement with the steroid regardless of genetics and total dosing. Not only will suppression occur, it will be significant in all men. For this reason, the use of exogenous testosterone with any Nandrolone compound is imperative. Those who do not include exogenous testosterone, the form of testosterone is inconsequential, will fall into a low testosterone state. Such a condition can be extremely unhealthy and carries with it numerous possible bothersome symptoms.
Once the use of Dynabolon and all anabolic steroids has been discontinued and all the exogenous hormones have cleared the system natural testosterone production will begin again. This is assuming no damage was done to the HPTA due to improper steroid use. It also assumes no prior low testosterone condition existed.
While natural testosterone production will begin again, it will be slow and you will be at risk of a low testosterone condition post steroid use. For this reason, most men are encouraged to implement a Post Cycle Therapy (PCT) plan in order to ensure a smooth recovery. This will stimulate natural testosterone production and protect your health. It will not return your levels to normal on its own, this will still take some time, but it will ensure you have enough testosterone for proper bodily function as your levels continue to naturally rise.
Dynabolon is not a hepatotoxic steroid and will not damage or stress the liver.
Dynabolon, while no longer available, was an anabolic steroid that was found in ampules that contained 80.5mg of the Nandrolone Undecanoate compound. In therapeutic settings, standard Dynabolon doses were normally 80.5mg every 7-14 days. In more aggressive situations, the total dosing could be increased by three to four times that amount.
For the athlete, two ampules per week in one single dose or two equal doses per week (1 amp tice per week) will provide the therapeutic benefits. This can be a great dose in a well-planned cutting cycle for endurance and recovery purposes. For the purpose of off-season mass gains, most men will find 4-5 ampules per week to not only be very beneficial but also very well-tolerated. Higher doses can be used, some men can tolerate as much as 600mg per week very well. However, such doses will increase the risk of side effects and most men will not need such doses to reach their goals. Regardless of the total dosing, you will find Dynabolon stacks well with all anabolic steroids. However, there is no reason to conjoin it with another Nandrolone hormone. This steroid, due to its very slow acting nature is not suited for short-term use. Use should be at least 10 weeks with 12-16 weeks being optimal.
Availability of Dynabolon:
Dynabolon is no longer available in any market. There is no legitimate pharmaceutical Nandrolone Undecanoate available in any market. However, you may be able to find a few underground labs that still make a Nandrolone Undecanoate compound, but they are not common and their quality is unverifiable.
Buy Dynabolon Online - Warning:
You may be able to buy Dynabolon online if you find a random underground lab supplier that carries it, but again it’s not common. With so much Nandrolone Decanoate and Nandrolone Phenylpropionate available, you will still be able to buy all the Nandrolone you want.
If you are able to buy Dynabolon online, keep in mind there is no way to measure the quality of this steroid. Further, if you live in the U.S. you will be breaking the law. In the United States anabolic androgenic steroids are classified as Schedule III controlled substances. Any purchase or possession of any anabolic steroid will require a prescription based on approved government medical need in order to be legal. While steroid prescriptions can be obtained, you cannot get a prescription for Dynabolon or any Nandrolone Undecanoate compound. You will find, however, the law is often far more lenient in many countries. In some countries you can legally buy anabolic steroids for personal use so as long as the purchase is made at the pharmacy. Conversely, some countries are similarly strict as the U.S. making understanding the law as it pertains to where you live imperative before purchasing any anabolic steroid.
Due to the steroid laws of the U.S. and other places around the world, in order to avoid legal trouble and poor product purchases you are encouraged to visit the sponsors here at Steroid.com. The sponsors here at Steroid.com can legally provide you with high quality anabolics without a prescription or fear of legal consequences.
Dynabolon is an excellent anabolic steroid, but as it is no longer available its quality is largely of no consequence. However, Dynabolon is virtually identical to Nandrolone Decanoate with the exception being a slightly longer activity time. You can obtain the same, identical results with Dynabolon or the more popular Deca Durabolin compound.
