DecaDurabolin in bodybuilding

bodybuilder takes anabolic

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

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.
