Decalab-250 is almost identical in its chemical skeleton to such an androgen as Testosterone. The only difference is the lack of a methyl group at position 19.

The most common and popular ester (variant) of Nandrolone is decanoate. Better known in bodybuilding circles as the Deca. This drug stabilizes the androgen receptor in skeletal muscle very well. About 2 times better than testosterone itself. And the better the steroid stabilizes the receptor, the more protein is synthesized by cells. The main thing is to have time to take protein food.

Decalab-250 does not aromatize and does not have estrogenic activity. So, the problems associated with Estradiol are excluded. In this case, this medication mimics the action of Progesterone and can cause a sharp increase in Prolactin in blood plasma. Under the influence of the enzyme 5 – alpha – reductase, Nandrolone is actively converted to Dihydronandrolone. Which, on the one hand, is completely inactive in the muscles and central nervous system, because of which anabolism and an increase in strength indicators suffer. But on the other hand, everything is not so bad, because if you are on the Decalab cycle you will not be threatened with androgenic side effects (acne due to DHT, baldness of the head, increased hair growth on the trunk and extremities, oily skin and sweating, prostate growth).

The definitely positive aspects of this medication include the ability to intensify the level of erythropoiesis (increase the total blood volume) on the course and actively increase the amount of fluid that lubricates the ligaments, joints and spine.


  • noticeable water retention in the body;
  • weight gain and muscle growth;
  • increased stamina and faster recovery;
  • increase in power indicators (in some cases does not occur);
  • increase in overall muscle endurance;
  • relief or complete elimination of pain in joints, ligaments and spine

Decalab-250 is used exclusively during the period of mass gain and strength increase. For this purpose, it must be combined with Testosterone (usually enanthate or Sustalab-250). Moreover, Testosterone in the course should be twice as much as Nanadrolone. In order to avoid problems with well-being, libido and erection, which can provoke Decanoate, often, courses are supplemented with Dianobol-lab 20 or Turano-lab 20. What definitely should not be combined is Primalab-100 and Boldelab-200 (all three drugs are similar in behavior in the body), as well as Trenbolone and Oxy-lab (both anabolics show progestin activity).


If you are using Decalab-250, then you should regularly take blood tests, and monitor the level of Prolactin in the body. To prevent it (Prolactin) bursts, Cabergoline (Dostinex) is used, usually half a tablet containing 500 micrograms strictly once a week.

In no case, you should not try to take it during cutting period – the ability of this steroid to retain water under the skin and the low androgenic effect will not allow you to make the shape that you are waiting for. This medication is very useful for athletes working with large weights, who constantly experience pain in the shoulders, elbows, knees and back.

Given the half-life of Decanoate (9-10 days), its injection should be performed once a week. And you can divide them into two times (Mon. and Thu, for example). The optimal duration for a Decalab-250 cycle is approximately 10 to 12 weeks or more. Using this anabolic steroid in short courses does not make much sense. The activity of the drug begins to appear at the end of the third week after the first dose and lasts 3-4 weeks after the final injection. That’s exactly what you need to wait before starting the PCT. The optimal weekly dosage of Decalab is approximately 200 to 600 mg. It depends on the experience of a particular athlete and on the amount of muscle mass that he already has.

  • Decalab-250 is extremely strong and most importantly it depresses the production of testosterone for a long time and upsets the spermatogenesis process;
  • due to the pronounced progestogen activity and a potential burst of Prolactin by the Pituitary gland, such sides are possible as: excessive water retention, active accumulation of fat (with “limping” nutrition), acne, weak libido and erection, depressive mood (eliminated by taking Cabergoline and Testosterone);
  • increased blood pressure, worsening of the lipid profile of the blood, heart palpitations (eliminated by drugs to lower blood pressure and dilute blood);
  • decreased neuromuscular stimulation (deterioration of the brain-muscle connection) due to the active conversion of decanoate to dihydronandrolone. And, as a result, a deterioration in the ability to concentrate, a depressed mood, a significant slowdown in anabolism and growth of strength indicators, a weakening of sensations in the working muscle during exercise (eliminated by the parallel intake of Testosterone). People with an excessive conversion of Nandrolone to DHN should generally abandon the decanoate ester and use short Nandrolone phenylpropionate – Nandrolab-P 100.
