DecaDurabolin in bodybuilding

Deca-Durabolin (Nandrolone Decanoate) is a powerful steroid for gaining muscle mass. In comparison with testosterone it has very low androgenic activity thou less androgenic side effects. It’s important to know that nandrolone is naturally produced in each person. The half-life of this steroid is 7-10 days.

Like withmany other esterified AAS, it takes time for the organism to detach ester and make this steroid active. That’s why Deca-Durabolin remains active for more than 2 weeks. Its conversion into dihydronadrolone explains low androgenic activity of this steroid, since dihydronadrolone is rather weak substance in comparison to dihydrotestosterone.

The effects of DecaDurabolin

  • Slowly increases muscle mass, but the gains are good.
  • Strengthens the bones
  • Reduces joint pain due to higher production of synovial fluid
  • Improves endurance and immunity

How to use

Medical doses do not provide high anabolic effects. Therefore, the doses for athletes are much higher and vary from 200 mg to 600 mg. The duration of a Deca cycles is about 2 – 2.5 months. It’s important to know that there is certain delay in effect.

Sometimes women take this steroid. Due to progestogenic properties it’s necessary to take Dostinex. Also don’t forget that proper nutrition is important to achieve optimal results. One cannot call Nandrolone Decanoate an ideal steroid, since there are more powerful AAS.
However, unlike those super drugs, Nandrolone is rather safe and suitable for everybody. Therefore it is so popular among athletes.


Bodybuilders know that while using Deca the best results can be achieved in combinations with other steroids. Besides, a combination may decrease adverse effects. Usually athletes combine it with Testosterone and Methane.
Here is an example of a very popular mass gaining combination with Testosterone Enanthate.

In order to reduce possible side effects you should include Proviron (Masterlone) and Dostinex into your cycle plan.

PCT is required after each Deca cycle. Remember that :tamoxife: nis not suitable in this case (also after Trenbolone cycles), since it increases the levels of prolactin. Therefore you have to chose between Clomid and Toremifene.

Side effects

Nandrolone has low level of aromatization, which is about 20% in comparison with Testosterone. Thus there are low risks of estrogen related side effects. However, in case of overdose they are possible. You can easily avoid them by taking aromatase inhibitors.

Like all 19-nor steroids, Nandrolone (as well as Trenbolone) has progestogenic activity which can cause estrogen-like side effects, including gynecomastia and water retention. In order to prevent them you should take Dostinex.

As we said above androgenic activity of DecaDurabolin is rather low (about 30% of Testosterone). However, one should remember that threshold of androgenic side effects is higher than in Testosterone or Methandienone.

Thus one cannot negate the possibility of androgenic side effects, which include acne, baldness and hypertrophy of prostate. In women it can cause virilization. We do not recommend to take Finasteride, since it is not effective against dihydronandrolone and may worsen the situation.

Deca is liver friendly, since it is not alkylated. Like all anabolic steroids Nandrolone can change the lipoprotein balance. It leads to reduction of high-density lipoproteins (HDL) and increases the risk of atherosclerosis. This side effect is dosage dependent.

Remember that anabolic steroids negatively affect blood pressure, triglyceride levels, and the ability of blood vessels to relax, which increases the risk of cardiovascular diseases. Thus, you should pay attention to your nutrition plan and include omega 3 fatty acids into your diet.

Nandrolone can significantly suppress HPTA. Scientists suggest that it is due to progestogenic activity of this drug. Therefore in order to avoid this side effect we recommend 0.5 mg of Dostinex two times a week. In case of long cycles it is necessary to take Gonadotropin.

Goals of combination

Dianabol and Deca-Durabolin is a classical combination for gaining mass and strength. If you follow the cycle properly, you can get up to 10 kg of muscle mass. Of course, this is the maximally possible result and it is not always achievable. However, in any case, this cycle will be effective and safe. Additionally this cycle may increase libido, improve endurance and strengthen joint-ligament system.

Characteristics of used drugs

Dianabol. The active ingredient of this steroid ismethandienone (methane). Athletes worldwide have been using this substance for more than six decades. Dianabol is good for gaining muscle mass and increasing strength.

Opponents of this steroid often indicate on itshigh hepatotoxicity. However, it was scientifically proved that at reasonable doses (30 – 40 mg daily) it is not toxic to the liver.

Nandrolone Decanoate (Deca-Durabolin). Along with methane, it is one of the most popular AAS among bodybuilders. Though itsanabolic action unfolds slowly enough, the final results can amaze an athlete. It also strengthensjoint-ligament system, and besides, improves immune system.

Proviron (Masterlone). Theactive substance of this drug is Masterolone, which belongs to a group ofantiestrogens. Proviron can effectively inhibit the enzyme aromataze, which converts testosterone into estrogens.
Due to the action of this enzyme, the levels of estrogen increase and estrogen-related side-effects become possible (e.g. gynecomastia).

Though this drug is not as powerful as other representativesof this group, its usage in this cycle is completely justified. The thing is that Decais almost unaromatizable, meanwhile methane has low rate of conversion.

Therefore, there is no need for more powerful antiestrogens (e.g. Exemestane). Their usage is necessary only in case of athlete’s genetic predisposition to aromatization.

Clomid. You shouldn’t use tamoxifenafter Nandrolone Decanoate cycle. Thus, you can choose only between toremifene and Clomid. Though their anti-estrogenic activity almost do not differ, the latter is more available.

Rules of providing course Dianabol and Nandrolone Decanoate

In order to make your cycle effective and safe, one should choose right dosage. We suggest you to use both steroids at moderate doses, which guarantees no side-effects. The length of a cycle is 5 weeks. This is enough for beginners. Experienced athletes can extend it up to 8-10 weeks.

Take Dianabol gradually increasing the dosage from 20 to 40mg/day, then gradually decrease the dosage in the same way. This “up-and-down-the-hill” pattern will help your body to adapt to this steroid.
In order to improve effectiveness of Dianabolit’s better todissolve the tablets under the tongue, rather than swallowthem. To make smooth hormonal background divide the daily dosage into several portions and take them at regular intervals.

The weekly dosage of Nandrolone Decanoate (Deca-Durabolin) is 0.4 grams. Therefore, the usual pattern of Deca-Durabolin administration is 200mg every third day. For example, you can take it on Mondays and Thursdays. This pattern will ensure a steady flow of steroid into the blood.

Take Proviron (Masterlone) starting from the second or third week of your cycle and go on until steroid withdrawal. The daily dose is 50 mg. Start PCT in seven days since last Decainjection. The daily dosage of Clomid is 50 milligrams. In most cases, three weeksis sufficient time for your body to restore.

You can find a lot of positive reviews about stacking of Dianabol and Deca-Durabolin the internet. It is not surprising, since the cycle provides excellent results and safetyat the same time.

If you follow the recommended dosagesand take auxiliary drugs, there will not be side-effects. The rollback after the cycle is minimal, which is important. Some novice bodybuilders complain about the loss of gained mass after steroid withdrawal.

This happens due to the wrong cycle. We have to remind that by using Proviron you not only suppress estrogen-related side-effects, but also water retention. As a result, your muscles do not swell. Therefore, after steroid withdrawal there are no losses.

If your cycle is long enough, take Dostinex in order to avoid progestogenicside-effects of Deca. This cycle is suitable not only for beginners, but also for experienced bodybuilders.
