Also known by trade names Libriol and Tribolan, Nandrolone Phenylpropionate is an anabolic steroid.
Nandrolone Phenylpropionate was first sold commercially under the name Durabolin in the 1950s.
It is very similar to Nandrolone Decanoate, sold under the name Deca Durabolin, which was introduced a bit later.
An injectable substance, this steroid was created by modifying the Testosterone molecule.
It is highly popular among athletes and within the bodybuilding community.
Many find this esterified form of Nandrolone to be appealing due to its versatility, which is commonly utilized in both bulking and cutting cycles.
With an anabolic rate of 125, this steroid garners a lot of support from bodybuilders who use it to add lean muscle.

Nandrolone Phenylpropionate (NPP) is an anabolic steroid with a small ester.
It is less commonly used than its longer-estered cousin, Nandrolone Decanoate, which was more widely available and thus, easier to buy.
Now, underground labs are producing NPP in larger quantities, making it easier to find.
Don’t make the mistake of thinking ‘easier’ means ‘easy.’
It is still illegal in the United States unless prescribed for specific medical applications, and it is actually quite difficult to come by. Bodybuilding is not considered a valid medical application for which doctors will write a prescription.
What’s more, all Nandrolone drugs are significantly suppressive to natural testosterone production. Intensive post-cycle therapy is highly recommended as this steroid has the propensity to be difficult to recover from.
Nandrolone Phenylpropionate is a 19-nortestosterone androgenic anabolic steroid. This type of steroid is made from Testosterone that has been modified at the 19th atom.
In the case of NPP, the modification is the elimination of a carbon atom at that location. This modification creates Nandrolone.
The addition of a short ester known as phenylpropionate creates Nandrolone Phenylpropionate.
All esterified and non-esterified forms of Nandrolone have a weak androgenic rating.
In comparison with Testosterone, Nandrolone Phenylpropionate is slightly more anabolic and significantly less androgenic.
NPP has an anabolic rating of 125, compared with Testosterone’s 100, and an androgenic rating of only 36, compared with Testosterone’s 100.
The reduced androgenic properties are due to the fact that Nandrolone is metabolized into Dihydronandrolone (DHN) instead of the far more androgenic Dihydrotestosterone (DHT).
This means users of this steroid enjoy a decreased risk of hair loss, a decreased risk of suffering from an enlarged prostate, and a decreased risk of suffering from acne.
In addition, NPP is less vulnerable to aromatization compared with testosterone, so the risk of estrogenic side effects are lower. A benefit of NPP (sometimes called Nandrolone Phenylprop) is the ability to reduce estrogen-related water retention.
Finally, Nandrolone Phenylpropionate functions similar to progestin in the body, which means it has some side effects that are unique from other steroids.
Additionally, the Nandrolone Phenylproprionate steroid offers the ability to cushion or buffer joints during heavy lifting.
It has a reputation for being less adverse to the user’s sex drive, but this has not been verified by studies.
Nandrolone Phenylpropionate functions essentially the same way as Nandrolone Decanoate except that it has a shorter half-life and enters the bloodstream a bit more quickly.
For this reason, users who wish to maintain stable blood levels of the hormone will need to inject it more often than Nandrolone Decanoate.
Deca Durabolin (Nandrolone Decanoate) allows for less frequent injections making it highly preferable for those who may be a bit squeamish in regards to needles.
The heavy injection schedule is the main downside of NPP cited by bodybuilders in Nandrolone Phenylproprionate vs. Deca discussions.
The recommended dose range in bodybuilder discussions around NPP is about 50-100mg per day, or about 100-200mg 3x/week.
More advanced users may go as high as 400-800mg/week. NPP is rarely used without a TRT dose of Testosterone.
For women, a dose of 50-100mg weekly is the limit of what is recommended.
These dosages are not backed by robust research because performance-use of Nandrolone is illegal in the US and many other countries. They are based on the personal and anecdotal experiences of bodybuilders in underground communities of bodybuilders. Dosages can far exceed what is medically recommended.
With a 4.5 day half life, Nandrolone Phenylpropionate NPP has the tendency to quickly build up to peak levels in the body and is much quicker to filter out of the body once injections are completed.
On the other hand, Deca tends to take much longer to both build up and trickle out of the body.
This makes Nandrolone Decanoate a poor choice for cycles lasting under 10 weeks, while NPP is a better option for these criteria.
Often times, those who are involved in competitive sports with be subject to drug testing for steroids and other disallowed substances.
These tests are typically conducted by measuring the level of Testosterone versus the Epitestosterone levels. If the Testosterone levels far exceed that of the Epitestosterone levels, one will likely fail the test.
In terms of steroid detection times, Nandrolone Phenylpropionate is detectable for between 11-12 months, much longer than Deca Durabolin’s 17-18 months of detection time.
NPP is known to provide a variety of performance and therapeutic benefits.
Next to Testosterone, Nandrolone may well be the anabolic steroid most commonly prescribed by doctors, though Nandrolone Decanoate is generally preferred over Nandrolone Phenylpropionate.
In terms of medical applications, NPP can be used for several conditions, including HIV, cancer, and muscle wasting diseases.
NPP can also be used to treat some cases of breast cancer, anemia, burns, ulcers, dwarfism, osteoporosis, and childhood developmental disabilities.
Generally, Nandrolone Phenylpropionate is observed to be well tolerated by most users, though it does carry some risk of side effects.
Furthermore, the drugs aromatizes (converts to estrogen) at approximately only 20% of the rate as that of Testosterone.
Therefore, potential Estrogen related side effects such as increased water retention, breast tissue growth (in men), and fat gains are typically not held to be a major issue.
Nandrolone is taken to boost red blood cell counts. Red cells are responsible for transporting oxygen throughout the body, improving endurance and helping to speed recovery for weight trainers.
As mentioned, the drug is sometimes used to treat anemia. That is an indication that raising red blood cell count and aiding in the delivery of oxygen to the muscles is a major part of the NPP results repertoire.
Moreover, the steroid Nandrolone Propionate is one of the few that has even been successful in helping AIDS patients realize significant weight gain.
Nandrolone is observed to increase levels of IGF-1 (insulin-like growth factor). IGF-1 is a hormone that aids in recovery after training and plays a role in several types of cells.
NPP also works to inhibit certain stress hormones known as glucocorticoids. These hormones influence our health and how we feel, but they can also increase fat retention and decrease muscle.
Physical exertion tends to increase stress hormones, and Nandrolone can bring them back down.
Nandrolone Phenylpropionate also boosts Nitrogen retention, which makes up 16% of muscle tissue. Increased nitrogen improves anabolism, while reduced nitrogen levels leads to catabolism.
NPP also stimulates cells to build proteins, which are the building blocks of muscle tissue.
The last advantage of NPP for performance users is that it is associated with boosts in collagen and bone minerals.
This can help strengthen bones and cartilage and improves the health of bones, cartilage, and joints.
Despite all the possible medical applications of NPP, in the USA it is generally limited to treat patients with AIDS, HIV, or severe anemia.
In other parts of the world, it is more widely used in medical applications.
During the off-season, most performance users of steroids go into a bulking cycle.
NPP and other variations of Nandrolone are felt to lend themselves to bulking phases as they are observed to be quite effective in increasing size and muscle mass.
Though NPP is fast-acting, the gains are reputed to be more steady than rapid.
Experienced PED users will stress the importance of consuming adequate calories for growth. Eating right is considered to be essential to getting the best results from NPP.
Some athletes will say NPP speeds up metabolism, leading to a leaner appearance. Post-training recovery is also reported to be easier with NPP.
As effective as NPP is purported to be for bulking, it is even more popular for use during cutting cycles.
During cutting cycles, it is common to lose muscle tissue along with fat. NPP is used to help protect against lean muscle loss.
Some bodybuilders use NPP in small doses to ease joint discomfort. While many pain relievers simply mask symptoms, NPP has a reputation for helping to heal the joints and offer real relief.
For all the positive effects associated with NPP in bodybuilding circles, it is important to remember that it can also produce some unwanted side effects.
While NPP is generally believed to be well tolerated, it is still important to be aware of them.
Consult with a physician before engaging in a steroid cycle such as Nandrolone Phenylpropionate.
Patients suffering from diabetes are warned to be especially careful as the drug has the potential to drastically reduce blood glucose levels.
For those patients, a personal blood glucose level monitor is strongly advised.
Those suffering from cardiovascular issues should exercise caution when using this steroid as it is also known to increase blood cholesterol levels.
The side effects connected with Nandrolone Phenylpropionate are generally considered to be milder than those seen with some other anabolic steroids.
Estrogenic – NPP is less aromatizable than some steroids.
However, estrogenic side effects are possible. Bloating, increased blood pressure, and swollen breast tissue in men are possible adverse outcomes.
Aromatase inhibitors are often taken to block these side effects.
Androgenic – Because NPP is so much less androgenic than Testosterone, androgenic side effects are milder but still present.
These side effects include oily skin, enlarged penis and hair loss.
Virilization – Women who use NPP may experience the development of secondary male sex characteristics such as:
Female users are advised by physique builders to discontinue use immediately if these symptoms appear.
For most women, these symptoms are reported to reverse after stopping use of the steroid. Continuing to use NPP after these side effects appear can cause the side effects to take longer to reverse.
In some cases, prolonged use can cause these symptoms to become permanent.
Cholesterol – NPP can reduce levels of HDL (good cholesterol).
Testosterone – As with most anabolic steroids, NPP will suppress the body’s production of Testosterone.
Physique builders use of supplemental Testosterone to maintain testosterone-related physiological functions in the body during a cycle.
The following are some other potential side effects.
It is highly recommended that Nandrolone Phenylpropionate be stored in a clean dry place with a temperature no greater than 30 degrees Celsius.
It is best not to store in the kitchen or near the bathroom sink in order to avoid excess moisture.
Also, it is best kept out of direct sunlight, nothing different than Deca Durabolinor many other drugs/supplements.
In the United States, NPP can only be legally obtained with a written prescription from a doctor for a specific medical condition.
Those in the US who want to purchase NPP for performance enhancement must obtain it from underground labs.
Nandrolone Decanoate is a bit easier to find, though it may cost more.
Though NPP is a controlled substance in the US, some people purchase it online from black market sources.
In the interest of legality and safety (unregulated sources often sell fake, contaminated, or expired product), we would like to encourage you to consider some legal alternatives to anabolic steroids.
These alternatives seek to offer many of the benefits of anabolic steroids without the side effects.
Not only are they legal, they are generally less costly and can help athletes achieve their goals in a sustainable and safe way.
