Description

NPP Deca 100mg contains Nandrolone bound to the phenylpropionate ester, which results in faster absorption and a shorter half-life compared to its longer-acting counterpart, Deca-Durabolin. This makes it suitable for athletes who want the anabolic benefits of Nandrolone without the long detection window or prolonged suppression.

NPP Deca 100mg is highly anabolic and moderately androgenic, making it effective for lean mass cycles, body recomposition, or as a supportive compound to enhance joint comfort and recovery. It increases nitrogen retention, red blood cell production, and collagen synthesis—leading to improved endurance, strength, and injury resilience.

It is particularly favored during off-seasons or bulking phases, but it can also be used in moderate doses during cutting to preserve muscle mass.

Benefits

  • Promotes lean muscle gain and strength

  • Enhances joint lubrication and connective tissue support

  • Improves recovery and endurance

  • Reduces inflammation in joints and tendons

  • Less water retention compared to longer esters

  • Faster acting with shorter detection time

Side effects
While NPP Deca 100mg is well tolerated by many, potential side effects include:

  • Suppression of natural testosterone production

  • Progesterone-related side effects (e.g., potential for gynecomastia even without high estrogen)

  • Acne, oily skin, or increased body hair (mild androgenic activity)

  • Water retention and bloating (milder than with other compounds)

  • Decreased libido if not stacked with testosterone

  • Mood swings or irritability

Proper cycle support and stacking with a base testosterone (e.g., Test Prop or Test E) can help prevent most side effects.

Dosages & Protocol

Dosages for Men:

  • Beginner: 300mg per week (3ml/week), split into 3 injections (e.g., Mon/Wed/Fri)

  • Intermediate: 400–500mg per week (4–5ml/week)

  • Advanced: 600mg per week and up, depending on cycle goals
    Due to its short ester, NPP Deca 100mg is typically injected every other day or 3x per week for stable levels

Dosages for Women:

  • Beginner: 25–50mg per week (0.25–0.5ml), split into two doses

  • Advanced/competitive users: Up to 75mg per week (0.75ml), depending on tolerance and experience
    Injection frequency: typically twice weekly to maintain more stable hormone levels and reduce risk of side effects

How to administer – reconstitution and how to inject
NPP Deca 100mg is a pre-mixed oil-based injectable and does not require reconstitution

Injection:

  • Use a 1–3ml syringe with a 25–27 gauge needle (1–1.5 inch)

  • Inject intramuscularly into the glute, thigh, or deltoid

  • Clean the injection site with alcohol, aspirate slightly, and inject slowly

  • Rotate injection sites to prevent scar tissue buildup

Storage
Store at room temperature in a cool, dry place away from heat and light
Keep the vial tightly sealed when not in use

Half life & detectability
Half-Life: Approximately 4.5 days
Detection Time: Detectable in the system for up to 8–12 months depending on testing sensitivity and duration of use
For athletes subject to drug testing, it is important to consider these detection times and plan accordingly to avoid positive tests for banned substances.

Dosage Instructions

Dosage Instructions

Your dosage of NPP will depend on whether you’re using it mainly for therapeutic purposes, or for performance enhancement. When using this steroid to gain benefit from its therapeutic effects only, males can dose at 100mg to 200mg weekly and see substantial benefit including greatly improved recovery and joint relief.

For guys using NPP for bodybuilding a dosage of up to 400mg weekly is ideal. This strikes the right balance between reaping the benefits while keeping the side effect risk to a minimum. Those who are less concerned about side effects might consider increasing the dosage a little beyond 400mg but for most male users this will be the sweet spot that will deliver excellent results.

NPP is not an extremely fast acting steroid so cycle length should provide enough time to really see the benefits that this highly effect compound can deliver. Up to 12 weeks is recommended. The frequency of injections should be three per week, where the weekly dose is split evenly between injections. A three weekly injection routine ensures that blood levels of this steroid are evenly maintained throughout the cycle.

Females can make use of NPP but must be aware of the risks of virilization, and for that reason the female dosage should not exceed 50mg weekly for no longer than a 6-week cycle.

Effect on Cycle

Effect on Cycle

Nandrolone is well known for its many positive benefits and effects when used for performance enhancement purposes. You’ll also find that this compound comes with some excellent therapeutic effects as well, making NPP a quality all round steroid that will suit a range of users and goals.

Here are the main benefits and effects that you can expect with NPP:

  • Mass building – NPP is an excellent mass builder, and many guys will include this steroid in every bulking cycle. Putting on quality muscle at a steady pace is a highly desirable benefit of NPP. This is not a compound that works super-fast to help you gain mass quickly, but if you’re after both high quality and high quantity muscle gains, then NPP delivers.
  • Recovery – NPP has excellent therapeutic benefits for the joints, and this is going to provide a significant boost to your recovery process. Expect to recover faster and be able to hit the gym for your next workout sooner, with greatly reduced muscle and joint soreness.

 

  • Lean muscle preservation – NPP has superb metabolic properties, and this will make it more efficient for you to maintain lean gains during the off season. Additionally, if used in a cutting cycle then NPP helps conserve your muscle mass while you work on losing fat. Again, this is thanks to the high metabolic properties of Nandrolone. While NPP is not commonly used as a cutting steroid as often as it’s used for bulking, it can provide a highly beneficial role in a cutting cycle for any user who understands its functions and benefits.
  • Strength – Some users may see some increase in strength, however NPP is not particularly known for its ability to significantly boost strength to a noticeable level. When stacking with NPP with other steroids, it is likely to be other compounds that take care of your strength boost as this is not an area that Nandrolone excels in.


Benefits:

  • Build Mass
  • Speeds up recovery
  • Preserves lean muscle
  • Boost strength


Nandrolone can be used for bulking or mass building, cutting, as well as for general athletic purposes. This makes it a highly diverse steroid that is often stacked with other compounds where it can contribute to more specific goals.

Side Effects

Side Effects

Every steroid will come with its own side effects profile risk, but experienced steroid users will be familiar with most of the potential side effects that can experience with NPP. Some of these are certain to occur because of the nature of using steroid hormones, while other side effects can be determined more by individual reactions.
Some guys will experience more severe side effects than others, but it’s important to be aware of everything that you could be dealing with, so you’re prepared to combat the side effects and focus on the positive benefits of NPP. This steroid can be considered one of the milder when it comes to side effects, however there’s no escaping some negative effects.
Here are the main side effects to expect when using NPP for performance enhancement:
Androgenic side effects: These effects are milder with NPP compared with many other steroids. This category of side effects includes acne and baldness, but only males who are predisposed to these conditions are likely to experience them and for most men, it will be relatively mild. Female users should be alert for signs of virilization like hair growth and deepening of the voice.

Estrogenic side effects: Nandrolone is an aromatizing hormone so estrogenic effects can come about when testosterone is converted to estrogen, although they are normally not as severe as with many other steroids. These include development of gynecomastia, water retention and associated increase in blood pressure. Users should be able to easily control these effects by using an aromatase inhibitor.

Testosterone suppression: As with all steroids, NPP is going to suppress your natural testosterone production and this effect is very strong when using this compound. For many guys it will only take one dose for most or even all your testosterone production to shut down. This can’t be avoided but must be mitigated by combining NPP in a cycle with a testosterone compound, so you don’t lose the vital bodily functions that this critical hormone provides. Following your NPP cycle you’ll need to implement post cycle therapy to speed up the stimulation of normal testosterone function again.

Cholesterol: Some users will experience a reduction in levels of good cholesterol (HDL) when using NPP. This effect can often be amplified through the combined use of an aromatase inhibitor, which many users are likely to also be taking to control estrogenic effects. Those with existing cardiovascular complications or high cholesterol should closely monitor cholesterol levels throughout, and all NPP users should incorporate a good amount of cardio work into workouts while maintaining a diet high in omega-3 fatty acids.

Liver toxicity: NPP is not known to be hepatotoxic in users who use the steroid sensibly and with suitable breaks in between cycles. However, all anabolic steroids can come with some risks to the liver, particularly when used at high doses or for prolonged periods of time.

Most male users of Nandrolone Phenylpropionate should be able to prevent or control the side effects well, and it’s more mild side effect profile makes it an appealing steroid to use for new users or those wishing to avoid the much more severe side effects that can be seen with some other compounds.
Female users may find that low doses of NPP bring about no or very little side effects, but this should be closely watched and when any signs of virilization begin the steroid should be stopped right away.

Half-Life and Detectability

Half-Life and Detectability

Half -life: Nandrolone Phenylpropionate (NPP) has a half-life of approximately 4.5 days. The half-life refers to the time it takes for half of the administered dose of the drug to be eliminated from the body. Due to this relatively short half-life, NPP is often injected more frequently. Detectability: NPP can be detected in the body for a significant period after cessation of use. Although its half-life is shorter, Nandrolone compounds are known for their long detection times. NPP can typically be detected in urine for up to 12 to 18 months after the last injection, depending on factors like dosage, duration of use, individual metabolism, and the sensitivity of the testing method used. For athletes subject to drug testing, it is important to consider these detection times and plan accordingly to avoid positive tests for banned substances.
