Nandrolone Phenylpropionate

Nandrolone Phenylpropionate is an anabolic steroid, often confused with Nandrolone Decanoate. While the two are similar, they are different compounds. Nandrolone Phenylpropionate was he first such compound sold commercially and was introduced in the 1950s. The name it was marketed under was Durabolin and then later Deca Durabolin was introduced.

Nandrolone Phenylpropionate is a small ester based anabolic steroid, and many people refer to it as NPP. Since it is a small ester, it didn’t gain the same popularity as the larger ester version, Nandrolone Decanoate did. However, it is still available and it continues to be used by those who get it from underground labs.

There are many benefits from the use of Nandrolone Phenylpropionate, both for performance and for therapy.

This is because of the benefits it delivers, but also due to it being well tolerated by athletes and those using it for medical needs.

Nandrolone Phenylpropionate is a 19-nortestosterone anabolic androgenic steroid. This means there is a change to the testosterone hormone in the 19th position. This change allows the compound to be created by adding the short Phenylpropionate ester. It is more anabolic than testosterone. The rating is Nandrolone Phenylpropionate at 125 and testosterone at 100. It is also less androgenic with a rating of 37 compared to 100 for testosterone.

The Nandrolone Phenylpropionate reduces DHN rather than DHT which is why it has lower androgenic activity. It also means it can be tolerated well at higher doses than testosterone. However, both of them aromatize. For Nandrolone Phenylpropionate, it is about 20% of the rate for testosterone. It is important to understand it does have a progestin nature and that plays a role in the possible side effects from using it.


Nandrolone Phenylpropionate is the same as Nandrolone Decanoate in regards to the hormone function.

However, Nandrolone Phenylpropionate has the shorter ester and that means it gives a burst when it is injected. It also has a shorter half-life. It has to be injected more often to get the levels in the blood to be stable.

Possible Side Effects

There are various side effects that can develop with the use of Nandrolone Phenylpropionate. It is important to be well aware of them before you decide to use it. Typically, this is a user-friendly steroid. However, the higher the dosage, the greater the risk of side effects developing. Most men can completely avoid such problems by carefully following dosing recommendations.


There are some possible estrogenic side effects associated with the use of Nandrolone Phenylpropionate. This can include:


High blood pressure

Water retention


There is a risk of androgenic side effects when you use Nandrolone Phenylpropionate in a cycle. However, they are rarely going to happen for males. Hair loss can occur for men using it, but this tends to be the result of a genetic connection to male pattern baldness for them. Some men who are highly sensitive may notice some acne development. Overall, it is extremely well tolerated by males. The use of a 5-alpha reductase inhibitor isn’t going to reduce the androgenic side effects of Nandrolone Phenylpropionate. It can actually increase it so do not add this to your stack!

Women may end up with androgenic side effects if they use Nandrolone Phenylpropionate. It is important to watch for any signs of virilization as they can be irreversible if you continue to take it once those symptoms are present. Such symptoms include:

Deeper voice

Enlarged clitoris

Unwanted body hair

It is important to keep a close eye on your cholesterol levels. Nandrolone Phenylpropionate can cause the negative cholesterol to increase and it can also hinder your good cholesterol. Always test your levels before, during, and after adding this to your stack. The use of an Aromatase Inhibitor can make this worse.  Make sure you eat a great diet and continue your cardio activities.


Such estrogenic side effects with the use of Nandrolone Phenylpropionate can be eliminated with the use of an Aromatase Inhibitor such as Anastrozole. The estrogenic effects can be the result of aromatizing, where the testosterone in the body is being converted into estrogen. The rate that it aromatizes though isn’t very fast, and that is why it tends to not cause too many issues for men.

Nandrolone Phenylpropionate is a progestin, and that can cause the mammary tissue to be stimulated. That is what can promote Gynecomastia for some men with sensitivity to the compound. Aromatase Inhibitors are strongly recommended to prevent this from happening.


Nandrolone Phenylpropionate doesn’t pose any threats to the functionality of the liver.


As is the case with all anabolic steroids, the natural production of testosterone is going to be suppressed. It only takes one or two injections for that to happen with Nandrolone Phenylpropionate. Make sure you use an exogenous testosterone to help offset this so you can avoid the side effects from not enough testosterone in the body. After all the Nandrolone Phenylpropionate is out of the body at the end of the cycle, your natural production levels will start again.

It is going to take time though for it to get back to the natural levels. A post cycle therapy plan should be in place to help kickstart this process for your body. If you already had low testosterone though before you started Nandrolone Phenylpropionate, it can be much more difficult to get the production up again.

Nandrolone Phenylpropionate Use

For medical use, the typical dose of Nandrolone Phenylpropionate is between 50 mg and 100 mg weekly. For females who are prescribed it for medical needs, it would be no more than 50 mg per week.

Most athletes and bodybuilders use a weekly dose between 100 mg and 200 mg. There are those that push it as high as 400 mg per week though in order to help them create and maintain lean muscle mass. Using anything more than that will significantly increase the risk of side effects associated with the use of Nandrolone Phenylpropionate.

The total weekly dose should be split into 1/3 with injections taking place every other day. The cycle is typically between 8 to 12 weeks for male athletes and no more than 4 to 6 weeks for females. Using it longer than that for women will increase the risk of virilization side effects.
