Dragon Pharma Nandrolone Decanoate (Deca 300/500) and Nandrolone Phenylpropionate (NPP 150), are two popular injectable anabolic steroids in Dragon’s line.

Effects of Deca 200/NPP 150

Nandrolone Decanoate, the active ingredient in Deca 200, has a long half-life, lasting up to 15 days, while Nandrolone Phenylpropionate (NPP), the active ingredient in NPP 150, has a shorter half-life, lasting up to 5 days. These two components give Deca 200/NPP 150 unique characteristics that make it a popular choice for bodybuilders and athletes.

How to use Deca 200/NPP 150?

When using Deca 200/NPP 150, it is important to follow a 14-week cycle. The recommended dosage for men is between 400-600 mg per week, divided into two injections per week for stable blood levels. This dosage is effective for building muscle mass and strength, but it is important to note that individual response may vary. It is crucial to closely monitor blood work to make any necessary adjustments.

For an advanced bulking cycle, Deca 200/NPP 150 can be stacked with other steroids such as Enantat 250 (Dragon Pharma Testosterone Enanthate) and Dianabol 20 for optimal results.

However, stacking should be approached cautiously, and monitoring for any adverse effects is critical. Arimidex can be used to control estrogen levels if needed.

Women should not use Deca 200/NPP 150 due to the extended release of Nandrolone Decanoate. This may lead to prolonged androgenic effects. It is important to note that post-cycle therapy (PCT) is necessary for both men and women.

For men, Clomid (Clomiphene) and HCG 2500 (Human Chorionic Gonadotropin) are recommended in addition to regular monitoring of blood work. For women, Nolvadex (Tamoxifen Citrate) can be used as PCT.

Possible Side Effects

One of the most common side effects of Deca 200 and NPP 150 is testosterone suppression. As these steroids are derivatives of testosterone, they can interfere with the body’s natural production of this hormone, leading to a decrease in testosterone levels. This can cause a range of symptoms, including decreased libido, erectile dysfunction, and depression.

Another potential side effect of Deca 200 and NPP 150 is gynecomastia, which is the development of breast tissue in men. This occurs because these steroids can convert into estrogen, which can stimulate the growth of breast tissue in men. Other estrogen-related side effects can include water retention, bloating, and high blood pressure.

Liver toxicity is another potential side effect of Deca 200 and NPP 150, although it is less common than with other steroids. These steroids are metabolized by the liver, and prolonged use can cause damage to this organ. Symptoms of liver damage can include jaundice, abdominal pain, and dark urine.

Finally, like all anabolic steroids, Deca 200 and NPP 150 can increase the risk of cardiovascular disease. This is because they can cause an increase in cholesterol levels, which can lead to the buildup of plaque in the arteries. This can increase the risk of heart attacks, strokes, and other cardiovascular events.


It is important to note that Deca 200 and NPP 150, like any other AAS, should only be used by adults over the age of 18. It should also be kept out of reach of children at all times. Before starting an Deca 200/NPP 150 cycle, it is essential to consult with a healthcare professional and get necessary blood work done to ensure the body is ready for the use of this drug.
