1.What Is Raw Nandrolone undecanoate powder? 

Nandrolone undecanoate 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, Nandrolone undecanoate 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.


Nandrolone undecanoate 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 Nandrolone undecanoate 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 Nandrolone undecanoate and all Nandrolone Undecanoate compounds would slowly disappear from the market.


D-Anabol 25 Nandrolone undecanoate 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, Nandrolone undecanoate 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 Nandrolone undecanoate with other existing Nandrolone forms.

2. How Does Raw Nandrolone undecanoate powder Works?

The effects of Nandrolone undecanoate 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 Nandrolone undecanoate 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 Nandrolone undecanoate, 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 Nandrolone undecanoate 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 Nandrolone undecanoate 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 Nandrolone undecanoate. As a great mass promoter, the effects of Nandrolone undecanoate 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 Nandrolone undecanoate 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 Nandrolone undecanoate, 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.

3. How to Use Raw Nandrolone undecanoate powder?

In bodybuilding, Nandrolone undecanoate is often used for mass build-up, as it has a strong anabolic and moderate androgenic effect. Due to the severe impairment of the bodys testosterone production, it is frequently injected with testosterone. Compared to nandrolone decanoate, the price and the need for frequent injections is a crucial drawback. For beginners and women the number of necessary injections is still within the scope. Professional Bodybuilders dont use Nandrolone Undecanoate, since noone wants to make several injections in one day.Nandrolone undecanoate is one of the steroids that is also used by women.


4. Dosage of Raw Nandrolone undecanoate powder

Numerous individuals are unaware of the possible results of using some particular Nandrolone undecanoate doses.Many bodybuilders use this steroid in the off-season bulking cycles so as to promote muscle size and growth.In case bulking is not the main target of the bodybuilder, lower Nandrolone undecanoate doses can be really beneficial.


It is enough to take 40-70mg of Nandrolone undecanoate per day in the off-season. For this, you will need to take one injection each week.To increase the efficiency of the steroid, the majority of bodybuilders will split the injection into 2 small equal size injections per week.This task will reduce the total injection volume. You can increase your dosage in case you tolerate 300-400mg without any problems.Even though there is no need for high dosages, we need to know that most men will support 60mg per week without any major problems.It is enough to stick with 400mg. It is more likely to experience negative side effects in case you increase the dosage.In some cases, the negative effects may outweigh the positive effects, even though this may differ from one person to another.

5. Warning of Raw Nandrolone undecanoate powder

You may be able to buy Nandrolone undecanoate 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 Nandrolone undecanoate 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 Nandrolone undecanoate 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 The sponsors here at can legally provide you with high quality anabolics without a prescription or fear of legal consequences.


6. What Are the Possible Side Effects of Raw Nandrolone undecanoate powder?

Nandrolone undecanoate has a low tendency for estrogen conversion,estimated to be only about 20% of that seen with testosterone.491 This is because while the liver can convert nandrolone to estradiol, in other more active sites of steroid aromatization such as adipose tissue nandrolone is far less open to this process.492 Consequently, estrogenrelated side effects are a much lower concern with this drug than with testosterone.Elevated estrogen levels may still be noticed with higher dosing, however, and may cause side effects such as increased water retention, body fat gain, and gynecomastia. 

An anti-estrogen such as clomiphene citrate or tamoxifen citrate may be necessary to prevent estrogenic side effects if they occur. One may alternately use an aromatase inhibitor like Arimidex® (anastrozole), which more efficiently controls estrogen by preventing its synthesis.Aromatase inhibitors can be quite expensive in comparison to anti-estrogens, however, and may also have negative effects on blood lipids.It is of note that nandrolone has some activity as a progestin in the body.

493 Although progesterone is a c-19 steroid,removal of this group as in 19-norprogesterone creates a hormone with greater binding affinity for its corresponding receptor. Sharing this trait, many 19-nor anabolic steroids are shown to have some affinity for the progesterone receptor as well.494 The side effects associated with progesterone are similar to those of estrogen, including negative feedback inhibition of testosterone production and enhanced rate of fat storage.Progestins also augment the stimulatory effect of estrogens on mammary tissue growth. 

There appears to be a strong synergy between these two hormones here, such that gynecomastia might even occur with the help of progestins,without excessive estrogen levels. The use of an antiestrogen,which inhibits the estrogenic component of this disorder, is often sufficient to mitigate gynecomastia caused by nandrolone.


Although classified as an anabolic steroid, androgenic side effects are still possible with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are warned of the potential virilizing effects of anabolic/androgenic steroids. 

These may include a deepening of the voice,menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Nandrolone is a steroid with relatively low androgenic activity relative to its tissuebuilding actions, making the threshold for strong androgenic side effects comparably higher than with more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone. It is also important to point out that due to its mild androgenic nature and ability to suppress endogenous testosterone, nandrolone is prone to interfering with libido in males when used without another androgen. 

Note that in androgen-responsive target tissues such as the

skin, scalp, and prostate, the relative androgenicity ofnandrolone is reduced by its reduction to dihydronandrolone (DHN).495 496 The 5-alpha reductase enzyme is responsible for this metabolism of nandrolone.

The concurrent use of a 5- alpha reductase inhibitor such as finasteride or dutasteride will interfere with site-specific reduction of nandrolone action, considerably increasing the tendency of nandrolone to produce androgenic side effects. Reductase inhibitors should be avoided with nandrolone if low androgenicity is desired.


Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. 

The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non aromatizable), and level of resistance to hepatic metabolism.Studies administering 600 mg of nandrolone decanoate per week for 10 weeks demonstrated a 26% reduction in HDL cholesterol levels.497 This suppression is slightly greate than that reported with an equal dose of testosterone enanthate, and is in agreement with earlier studies showing a slightly stronger negative impact on HDL/LDL ratio with nandrolone decanoate as compared to testosterone cypionate.498 Nandrolone injectables, however, should still have a significantly weaker impact on serum lipids than c-17 alpha alkylated agents.

Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides,reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration.Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.


All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. For sake of comparison,studies administering 100 mg per week of nandrolone decanoate for 6 weeks have demonstrated an approximate 57% reduction in serum testosterone levels during therapy.At a dosage of 300 mg per week, this reduction reached 70%.499 It is believed that the progestational activity of nandrolone notably contributes to the suppression of testosterone synthesis during therapy, which can be marked in spite of a low tendency for estrogen conversion.500 Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 2-6 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.
