Nandrolone Phenylpropionate overview

Write By: admin Published In: Steroids in bodybuilding Created Date: 2017-02-24 Hits: 27948

Nandrolone Phenyl Propionate is not so common form of Nandrolone.

The only difference between Nandrolone phenyl propionate and Deca is of ester only.


Nandrolone Phenylpropionate (NPP) is the newest form of Nandrolone.

Both Deca (the first form of Nandrolone that was created) and NPP have the same substance, but the only difference is the ester attached to them, which controls the speed and length of their action (the half-life).

NPP is the shorter ester of Nandrolone, which means it should be taken more frequently, but this is one of the only negatives of the steroid.

In fact, NPP was created especially to be able to avoid as many of the side effects associated with Nandrolone.

To achieve maximum benefits from the steroid, the NPP dosage should be 50 to 100 mg per injection, which is generally every other day. You don’t need to use the steroid in cycle for any longer than 10 weeks.

Nandrolone Phenylpropionate is very effective when it is used with other short-ester steroids.

In order to prevent aromatization, you must use an aromatase inhibitor such as Anastrozole, Letrozole or Exemestane.

NPP can be stacked with Testosterone, Dianabol, Masteron or Trenbolone.


Nandrolone is mostly used for treating the HIV/AIDS patients since it prevents the muscles from deteriorating. Some people are of the opinion that using the longer ester steroid (Deca) would be better for this purpose.

Nandrolone has the ability to treat anemia, because it increases the number of red blood cells in the body. Red blood cells are responsible for delivering oxygen to the muscles which is beneficial for increasing endurance.

Nandrolone also provides significant support to the immune system of the body. Collagen synthesis in the body is also enhanced with the use of Nandrolone, therefore, many bodybuilders use this steroid to treat joint issues.

Nandrolone is not highly androgenic, but it possesses a greater number of anabolic qualities as compared to testosterone.



Many users think that Nandrolone is not severe steroid, and it does not cause large number of side effects. But the steroid will affect each person in a different way.

One negative feature of NPP is that it can cause disturbance while restoring the natural production of testosterone in the body after the completion of a cycle.

Similar to Trenbolone side effects, Nandrolone can also increase the level of prolactin in the body, which can lead to progestogenic side effects.

Reviews from users of NPP have even reported a depressed feeling.

Erectile dysfunction and decrease in sex drive can also be experienced with the dose range of 200 to 400mg weekly.

This effect is experienced highly when no testosterone is supplemented with NPP.


A properly designed Nandrolone cycle allows athletes to obtain the following results:

• Accelerated muscle growth

• Increased physical fitness and stamina

• Stimulation of breakdown of fat deposits

• Improved appetite

• Getting rid of fluid accumulation in muscle fibers

• Strengthened immune system and improved overall health


Nandrolone Phenylpropionate is the better choice pre-competition than Deca Durabolin as NPP leaves the body within three weeks, and it cannot be detected after that time. However, Deca can be detected in the body after 18 months. This is one of the major differences between the steroids.

The injections of NPP can cause some pain at the site of injections. Deca does not have this property and it does not cause pain to the user. However, there are other side effects of Deca that are not commonly seen with the use of NPP.


The perfect bulking cycle would be any NPP steroid combined with any Testosterone Propionate steroid.

These two fast-acting steroids in a dosage of 300mg weekly for a duration of 10 weeks can provide huge results.

Both steroids would require 100mg injections every other day of the week.

You should be aware that if you combine NPP with a huge quantity of testosterone it will highly aromatize, and side effects like water retention and gynecomastia can be experienced.


You should never take NPP or any other steroid before you are completely aware about their reaction on your body.

You should take smaller doses if you want relief in the joints and should take lower doses when you are running a cutting cycle.

NPP should not be used for smaller cycles as it stays in the body for longer period of time.

It should never be used by women because the side effects that it causes in females are severe and they take a very long period of time to reverse.

NPP reviews online will often discuss the benefits of the steroid for lubricating the joints. Deca is generally the preferred choice in this case within bulking cycles. However, due to the NPP half life being so much shorter, it is the best “wet” steroid to use for cutting cycles.

Most bodybuilder reviews of NPP will mention how they always take a low dose of NPP during their Winstrol cycles, since stanozolol dries out the joints to a point where they may become sore. NPP is one of the only steroids which is perfect for this situation if the aim of the cycle is for cutting.

NPP has been a great addition to my workout routine. I've seen amazing NPP steroid results in just a few weeks and I haven't experienced any NPP steroid side effects. It's definitely worth trying if you're looking for a new way to boost your workout results.

Nandrolone phenylpropionate is a powerful anabolic steroid that can help you bulk up quickly. It has a short half-life, so you'll need to inject it every day or every other day. I've found that the best NPP cycle and dosage for me is 300-400mg per week, for at least 8 weeks to see significant results.

NPP steroid is amazing, indeed! Using Test Pro in addition to this, I completed an 8-week off-season cycle. ran 400 mg of test pro, and by week six, I had added NPP. All I could say after using the NPP dosage for 450 mg a week was that my strength and bulk gains skyrocketed. The nandrolone phenylpropionate benefit I am getting is that I was able to add an additional 25 pounds to my squat rack, reaching 350 for 8 reps as opposed to 300 for 4.

I am currently in my NPP cycle, pinning twice a week to aid in the recovery of various injuries. Despite using a relatively low amount of 200 mg NPP dosage per week for joint prevention and healing, I did not gain weight or raise my blood pressure.

On using nandrolone phenylpropionate, my joints felt wonderful. Although I was in my off-season, I did have a wet appearance. Even at low nandrolone phenylpropionate dosage, this aids in gaining muscle and greatly reduces joint pain.

Trenbolone reviews on a bodybuilding forum. I was looking for something that would give me some good results without being too harsh on my body. After reading some reviews, I decided to give it a try. I started out by doing a short 4-week cycle. I was really happy with the Trenbolone cycle effects. I felt more energy and my muscles were looking more defined.

start if you are seeking serious pounds of mass. This potent anabolic steroid will help you pack on the pounds quickly and effectively. The trenbolone cycle effects I experienced were great, putting on 20lbs of solid muscle mass. The side effects of trenbolone were minimal for me, with only a slight increase in aggression and libido.

lone acetate at 400mg and 600mg Deca per week. Take 1 to 2 weeks off after your cycle. Eat plenty of protein, drink lots of water and stay active during the entire cycle. This will help keep unwanted water retention down, which may prevent a dramatic weight gain during your cycle.

of the rumors that you had to have a certain body fat percentage and other things, I was hesitant to order it. When I bought this product, I weighed 220 pounds and had a body fat percentage of 12 to 15 percent. I took a Trenbolone-only cycle, and as a result, I gained over 30 pounds of muscle mass and lost 15 to 20 percent body fat. I was a believer in Trenbolone enanthate. I needed to buy brand-new clothing!
