Nandrolone phenylpropionate is an anabolic steroid very similar to the popular compound nandrolone decanoate. However, nandrolone phenylpropionate was the first Nandrolone compound ever to be marketed. Nandrolone phenylpropionate hit the shelves in the 1950s and was brought to market by Organon under the name Durabolin. Shortly thereafter, Organon will release its Decanoate cousin called Deca Durabolin.
Nandrolone phenylpropionate is a small ester anabolic steroid commonly referred to as NPP. This product has never been as popular as the larger version of ester decanoate due in part to availability; however, the modern era has seen a resurgence in both usage and availability, thanks in part to clandestine labs.
Nandrolone phenylpropionate has numerous therapeutic and functional benefits. The hormone nandrolone is the most commonly prescribed anabolic steroid other than testosterone, but the decanoate version is the most commonly prescribed form of nandrolone. It is one of the most well-tolerated steroids in both performance and medical terms, although possible side effects certainly exist.
General reviews about NPP
Nandrolone phenylpropionate is a 19-nortestosterone (19-nor) anabolic androgenic steroid. The 19-nor classification refers to a structural change in the hormone testosterone, which consists in the removal of a carbon atom in the 19th position. This simple structural change gives us nandrolone, and the addition of a short phenylpropionic acid ester gives us nandrolone phenylpropionate.
The function of the hormone nandrolone phenylpropionate is identical to nandrolone decanoate. Both forms consist of the same active hormone. In the case of NPP, we have a shorter version of the ester that gives more nandrolone release after injection, but also has a much shorter half-life. This means that nandrolone phenylpropionate must be administered more frequently than its larger ester counterpart in order for blood levels to remain stable.
Nandrolone phenylpropionate is slightly more anabolic than testosterone with a rating of 125 compared to a testosterone rating of 100. It is also significantly less androgenic with a rating of 37 compared to a testosterone rating of 100. The decrease in androgenicity is due to the hormone nandrolone being reduced to dihydronandrolone (DHN) instead of dihydrotestosterone (DHT). This is one of the reasons why nandrolone phenylpropionate may be well tolerated by some men at higher doses than higher testosterone doses.
Nandrolone phenylpropionate is also significantly less estrogenic than testosterone. Both nandrolone and testosterone aromatize, but nandrolone does this about 20% faster than testosterone.
Positive impacts of NPP on athlete’s body
Nandrolone phenylpropionate has many positive traits that are similar to many anabolic steroids and is considered an NPP fat burner. However, this compound also has functional characteristics that far outweigh what some steroid hormones are capable of. The positive functional characteristics of nandrolone phenylpropionate include:
Increased production of IGF-1: Insulin-like growth factor-1 (IGF-1) is a powerful anabolic hormone that is also important for our body’s ability to recover. It is a hormone that affects almost every cell in the human body.
Suppression of glucocorticoids: Known as stress hormones (cortisol), these hormones are essential for our health and well-being. However, glucocorticoids can also contribute to muscle loss and weight gain when they become dominant. Vigorous activity can lead to increased levels of stress hormones. Hormones such as nandrolone can reduce the production of stress hormones.
Increased Nitrogen Retention: All muscle tissue is made up of 16% nitrogen. If the delay drops, we fall into a catabolic state. The more we save, the more anabolic we remain.
Possible side effects of nandrolone phenylpropionate
There are several possible side effects of using nandrolone phenylpropionate, but it is also one of the more beneficial side effects. The key to managing and preventing side effects is understanding how they occur and using the hormone correctly. Most men should avoid serious side effects entirely. To understand the side effects of nandrolone phenylpropionate, we have divided them into separate categories.
- Possible estrogenic side effects of nandrolone phenylpropionate. The estrogenic side effects of nandrolone phenylpropionate include gynecomastia, water retention, and high blood pressure caused by severe water retention. These side effects can be avoided with an aromatase inhibitor (AI) such as Anastrozole (Arimidex).
The reason for the estrogenic side effects is due to the aromatization of the hormone nandrolone. Aromatization refers to the conversion of testosterone to estrogen. However, the rate of aromatization by this hormone is slow, but high enough to cause problems for some men. It is also a progestin and progesterone can activate breast tissue and promote gynecomastia in very sensitive men. AI-based on estrogen or progesterone will provide the necessary protection.
- Androgenic side effects of nandrolone phenylpropionate are possible, but they are unlikely in men. Hair loss is possible in men prone to male pattern baldness, and acne in sensitive men. However, when it comes to such effects, it is one of the most well-tolerated steroids. The greatest role will be played by genetic predispositions.
Although the hormone nandrolone is not extremely androgenic, it may contribute to the development of virilization symptoms in women. Virilization symptoms may include growth of body hair, deepening of the vocal cords, and enlargement of the clitoris. Some women can use low doses without problems but should be stopped immediately if symptoms appear. If you stop taking it when symptoms appear, they will disappear. If you ignore the symptoms and continue taking them, they may become irreversible.
- Nandrolone phenylpropionate can have a negative effect on HDL cholesterol (good cholesterol) and maybe somewhat more significant than testosterone. This negative effect can be exacerbated by the use of AI.
It is more than possible to use nandrolone phenylpropionate without cholesterol or cardiovascular problems, but a healthy lifestyle is a must. Regular cardiovascular activity is important, as is a cholesterol-friendly lifestyle.
- The use of nandrolone phenylpropionate suppresses the natural production of testosterone. As with all nandrolone compounds, a single injection will suppress almost if not all of your natural testosterone production. Your genetics won’t prevent this, and it’s completely unavoidable when used. In this regard, it is absolutely essential that all men taking this steroid use it along with some form of exogenous testosterone. This will prevent the decline in testosterone levels, which is accompanied by many very undesirable symptoms.
Other important features of the medication
Increased collagen synthesis and bone mineral content: This refers to the strength of bones and cartilage, as well as their ability to strengthen and facilitate healing. This applies to the joints more than anywhere else. Before taking this medication it is strongly recommended to read NPP real reviews.
Nandrolone phenylpropionate is also well suited for treatment in many areas. Although nandrolone decanoate is more commonly used, the phenylpropionate version is still used with some regularity. The use of nandrolone phenylpropionate has been proven to be beneficial in the treatment of the following illnesses:
- Diseases that cause muscle wasting: cancer, HIV, etc.
- Reduced geriatric weakness and fatigue
- Mammary cancer
- Treatment of burn victims
- Pituitary dwarfism
- Developmental delay in children

General conclusions on NPP cycles
Despite its many benefits and uses, in the US, nandrolone is usually prescribed only for HIV, AIDS, and anemia. Its effectiveness in other areas is high, but it is usually used in such areas of medicine outside the United States. Some physicians in the US have started prescribing it for anti-aging purposes, but this still makes up a very small fraction of the total prescriptions.
The hormone nandrolone is one of the most valuable anabolic steroids; five without a doubt. From a medical standpoint, it’s an incredible hormone, although the phenylpropionate versions have never been given their full potential. It’s not because of its inferiority, it’s just that the medical world really doesn’t need more than one nandrolone hormone, and decanoate is just the one it chose.
For a steroid user, this steroid can be called indispensable in the off-season. But if we look at what he can do for recovery and healing, he is almost in a class of his own. Add to that its side effect friendly nature and this steroid is very hard to beat. However, there is one important thing that we have yet to address – erectile dysfunction.
Nandrolone is well known for causing erectile dysfunction, which is often referred to as “Deca Dick”. It’s not the hormone’s fault; it is due to misuse. With both progestin and the hormone that can produce prolactin, erection function can be reduced. Keep your hormones in balance and you won’t have any problems.
