History and Overview

Deca Durabolin is the brand name for Nandrolone Decanoate, which is nothing but the ester variant of Nandrolone. Informally known as “Deca”, this steroid is ranked second on the list of the top three most utilized and popular anabolic steroids currently available on the market. There is no surprise that the first place is held by Dianabol (Methandrostenolone), while the third is held by Winstrol (Stanozolol).

There are good reasons why Deca Durabolin is not only highly regarded by athletes and bodybuilders, but also by the medical community.

In 1960, Nandrolone Decanoate was introduced in the scientific community, becoming the first anabolic steroid developed. Developed initially by Organon, it became available on the prescription drug market in 1962. However, not many people know that Nandrolone actually existed in 1957, as the Nandrolone Phenylpropionate ester variant.

Despite its popularity, the very short half-life of Nandrolone Phenylpropionate limited its use. The compound required every-other-day injections. This is why Nandrolone was reinvented by affixing the decanoate ester, thus becoming Deca Durabolin. Due to the decanoate ester, Nandrolone gained a longer half-life (approx. 15 days).

The new compound has ever since been enjoying extensive use as a medicinal drug and gained popularity among athletes and bodybuilders due to its ‘mild’ nature.

Is It Legal To Use And Buy Deca Durabolin in the UK?

The UK anabolic steroids law categorizes steroids as Class C substances and allows UK residents over 18 to use them. Nonetheless, it goes against the law to, supply, export, import, or make steroids with the clear intention of selling them to other entities without obtaining a license. However, it is not illegal to purchase and own anabolic steroids as long as you do so for personal use.

Due to the illegality of selling these drugs, it can make it difficult to source.

When it comes to buying steroids, UK residents have to rely on Internet providers or in person dealers rather than the traditional “brick and mortar” shops.

There is a 100% legal equivalent to this steroid that can be bought easily and without the breaking of any laws. This supplement is called Decaduro. You can find info on this muscle builder below.

What about the USA and the rest of the world?

The USA is extremely strict when it comes to anabolic steroids. It is illegal to distribute and even own them for your own personal use.

Canada and Australia have laws which are more in line with the UK. Many parts of Europe also have the same type of laws.

Best place to buy Decaduro?

The best place to purchase this legal supplement is directly from the manufacturer. Buying in this way eliminates the chances of buying fakes. There have been reports of fakes popping up more and more. Do not worry, the link below will take you directly to the manufacturer.

What does this steroid do?

Most athletes and bodybuilders reserve Deca Durabolin for bulking, strength-gaining, and mass-adding cycles. This is partially due to the compound’s positive effects on bone and connective tissue, increasing the healing rate and preventing injuries during intense physical activity.

Deca Durabolin promotes an increase in collagen synthesis to a higher extent than many other anabolic steroids. Studies have demonstrated its ability to also promote an increased bone mineral content, thus promoting beneficial effects on joint and connective tissue, considerably strengthening them during strength gaining, mass gaining, and bulking cycles.

As one would expect from a anabolic steroid, Deca Durabolin promotes the increase of muscle mass. However, a person cannot build muscle by simply using the drug. Physical activity and diet are also determining factors. It will simply help you to complement efficiently what you are already doing correctly to build muscle mass.

Deca Durabolin also acts as an impressive healer. The steroid has been proved to promote the gradual elimination of persistent pains and severe injuries. Furthermore, it strengthens the immune system, improves bone density, and boosts the collagen production. For all these reasons, Deca Durabolin is recurrently used on patients with AIDS who have compromised immune systems.

How does it work?

As far as its anabolic effects are concerned, Deca Durabolin is slightly stronger than Testosterone. Its anabolic ratio is at 125, while the anabolic rating of Testosterone is 100. However, Deca has a low androgenic rating (only 37), thus being favourable to users who are sensitive to androgenic side effects.

Moreover, this drug has a very low Estrogenic activity, binding poorly with the aromatase enzyme (this enzyme is responsible for converting androgens into Estrogen). Only 20% of Deca is actually converted into Estrogen.

This low estrogenic activity is due to the fact that Deca Durabolin is a Progestin (all 19-nor compounds are Progestins). At a closer look, we will notice that Deca does experience aromatization in the liver. However, it is resistant to aromatization in areas that usually experience a higher degree of Estrogen conversion (for example, in fat tissue).

One particular aspect worth addressing is the popular idea that Deca Durabolin benefits bone tissue and the joints. Though this idea is true, some popular explanations – such as ‘Deca lubes the joints’ – are actually misconceptions. What Deca actually does is promoting a significant increase in collagen synthesis and in bone mineral content. This means that athletes and bodybuilders will experience beneficial effects on joint and connective tissue during strength gaining, bulking, and mass gaining cycles.

The simplest way to explain what is does and how it works is that, progesterone-like hormones help build muscle mass, strength, and sooth joints. While used with other strong androgens that counteract its possible side effects, users do not normally experience severe side effects. However, in the case of a Deca only cycle, you can expect to experience libido and sexual disorders, bloating, and gynecomastia.

Dosage and use

Since we are talking about the long-acting estered variant of Nandrolone (with a half-life of approx. 15 days), a cycle should last at least 12 weeks. Due to its long-acting nature, users are unlikely to notice its effects until at least a couple of weeks after starting the cycle. This is why many users opt for a kick-starting oral compound (e.g. Winstrol, Dianabol, Anavar etc.) during the first weeks of their cycle. However, for bulking and strength gaining purposes, users generally opt for more suitable compounds such as Anadrol or Dianabol.

However, one of the most popular and efficient stacks among athletes and bodybuilders is the stack of Deca, Testosterone, and Dianabol. Simply put, this is the most popular steroid stack in history. Popularized in the 60s and the 70s, this stack is suitable for any type of user (from beginners to advanced users) and will deliver outstanding, quality gains.

Beginners usually opt for dosages ranging between 300 – 500mg per week, while intermediate users may go a little over the 500mg mark and stack with compounds such as Testosterone. Advanced users usually opt for dosages ranging between 600 – 800mg (sometimes even higher).

Deca Durabolin side effects

Though Deca is considered a ‘mild’ anabolic steroid (especially if compared with other similar steroids), there are several side effects users should be aware of. Since Deca Durabolin has a low aromatization rate, the estrogenic side effects of Deca are less severe than in the case of other anabolic steroids.

Even though the estrogenic side effects are not totally eliminated, they are easily manageable. The estrogenic side effects may include water retention, bloating, high blood pressure, and gynecomastia.

Since it is a Progestin, this compound may also increase the Prolactin levels in the body. As a result, side effects such as puffy nipples, bloating, gynecomastia, etc. may appear. However, aromatase inhibitors and anti-estrogens (e.g. Cabergoline, Bromocriptine) can effectively combat these side effects. The regular use of vitamin B6 can also control the Prolactin levels.

Though Deca Nandrolone is not a C17-AA anabolic steroid, androgenic side effects may appear: oily skin and acne, facial and bodily hair growth, increased risk of MPB, and increased risk of BHP (i.e. benign prostatic hyperplasia).

It may also cause side effects that are very common among the vast majority of anabolic steroids: disruption of the Hypothalamic Pituitary Testicular Axis, cholesterol alterations, and cardiovascular disorders.

One of the most feared side effects of Deca (especially among males) is the one popularly called, Deca Dick. This effect refers to the user’s inability to maintain (and sometimes even obtain) an erection. In addition, users might also have to deal with a severely suppressed libido. The reason is simple: when supplementing with anabolic steroids, the body’s natural testosterone production is suppressed to a small or large extent. In the case of this drug, users deal with total suppression.

Even 100mg of Deca Durabolin is enough to fully suppress the testosterone production. However, there is a simple solution: provide our bodies with the adequate dosage of exogenous testosterone.

Can it Damage The Liver?

Liver toxicity and, consequently, liver damage, are a serious concern when it comes to the use of anabolic steroids. However, since Deca is not a C17 alpha alkylated compound, the liver experiences no damage or stress whatsoever.

Can it Cause Hair Loss?

As mentioned before, side effects may include hair loss, acne, and body hair growth. However, the androgenic activity is very low. As a consequence, most men have no reasons to worry about MBP. And this happens mainly because Deca’s androgenic side effects are highly dependent on genetics. Those users who are genetically predisposed to MPB may experience hair loss. Though at some point, it was going to occur anyway, this steroid may speed up the process.

Will it Make Me Aggressive?

Due to its mild nature, Deca Durabolin is highly unlikely to cause behavioural changes and increased aggression. However, should you experience increased aggression and severe behavioural changes, it is recommended to stop its administration and ask for your physician’s advice.
