    What are Esters?

    Esters are basically chemical compounds that are responsible for manipulating and creating different forms of a similar androgenic base. Most of the steroid alternatives are created by this chemical compound, including NPP and Deca.

    What is Deca (Nandrolone Decanoate)?

    Nandrolone decanoate is also popularly known as Deca nandrolone. It is found in the form of light yellow crystalline powder and has a molecular weight of 428.65. So, now that you know what is Deca steroid, have a look at the right dosage of it.


    Deca is a very slow performing steroid, so it is not needed to be frequently injected. For athletes, it is always recommended to begin from 100mg per week and increase later if needed. Men can continue the intake for 8 to 12 weeks. For females, the dosage is 50mg for 4 to 6 weeks.

    What is NPP (Nandrolone Phenylpropionate)?

    If you are wondering what NPP steroid is, then in simple words, it is a chemical compound that is white in color and found in the form of crystal powder. Its chemical name is nandrolone phenylpropionate, and its molecular weight is 406.57.


    The standard NPP dose is around 50 to 100mg per week. Although it is not much prescribed for female athletes, the right dosage for them is considered to be 50mg per week. Athletes who want to enjoy the improved therapeutic advantage of NPP steroid can extend the dosage up to 200mg per week and for muscle building, 400mg per week.

    NPP vs Deca Comparison

    Muscle Gain

    In the battle of NPP vs Deca, NPP is far ahead than Deca in terms of muscle gain. The results using the former can be observed within 1 to 2 weeks, whereas the same results are provided by the later after a minimum of 4 to 5 weeks.

    System Clearing

    Nandrolone phenylpropionate wins again in the Deca vs NPP argument because of its faster system clearing process. It can clear your body within 10 to 12 months, whereas decanoate requires more than 18 months to do the same.

    Frequency of Injections

    Although nandrolone phenylpropionate won the last two points against nandrolone decanoate, people prefer decanoate more because of its lower frequency of injections. The half-life of NPP is around 2.5 days, whereas Deca comes with a longer half-life of around 6 days and stands as a winner in the Deca vs Tren battle too.

    mg/ml Ratios

    If you are wondering what Deca do to get more preference, then the ratio of both also plays an important factor here. Most of the athletes are comfortable in taking 200 gram of decanoate from a single 1 ml syringe.

    Nandrolone Side Effects

    Severe Insomnia

    One of the most disturbing nandrolone side effects includes insomnia. As it contains androgen, its use on men often causes sleep disturbances. This mostly happens because of the increase in testosterone levels in the body.

    Man Boobs

    Another NPP side effects include man boobs. When the testosterone level increases in the body, the body tries to balance the increasing testosterone level with oestrogen. Soon after the cycle gets over, the oestrogen level increases and gives rise to gynaecomastia.

    Cardiotoxic Effects

    Nandrolone when taken in excess gives rise to cardiotoxic effects which have harmful impacts on your cardiovascular system. Deca steroid side effects mostly include hypertension-related problems.

    Testosterone Decrease

    Although testosterone level increases initially, studies show that once you stop taking nandrolone, there is a steep decrease in testosterone levels. Just after four days of use, studies have observed a reduction in the levels of bioavailable testosterone in the body.
