    Ran 400mg NPP + 300 test prop for 12 weeks. Kicked in by week 3, joints felt amazing. Gained 15 lbs, mostly lean. Only downside — pinning EOD is a pain, but worth it for the faster results compared to Deca.

What is Nandrolone Phenylpropionate?

Nandrolone Phenylpropionate, or NPP, is an injectable anabolic steroid, primarily used for muscle mass and strength gains. One of the unique characteristics of NPP is the fact that it can be used by both men and women (in different dosages).

Nandrolone Phenylpropionate is a testosterone derivative, similar to Deca-Durabolin. Deca-Durabolin and NPP are quite alike in their anabolic profiles. However, the half-life of NPP is 4 days, whereas Deca Durabolin half-life is estimated at 14 days.

Nandrolone Phenylpropionate acts faster, meaning you’ll see results sooner, adding +1–2 lbs per week.

Nandrolone Phenylpropionate Benefits

Some of the NPP advantages include:

  • Solid muscle gains: athletes can increase their muscle mass by 15–20 lbs in 10 weeks;
  • Increased strength & endurance: enhanced muscle recovery and oxygen supplementation during the workout result in strength gains on all major lifts and more reps per set;
  • Aesthetic effects: muscles look fuller, veins become more visible;
  • Suitable for beginners: beginners can expect huge muscle mass and strength gains;
  • Joint health: NPP stimulates collagen synthesis, providing additional joint support;
  • Comparably low side effects: NPP is considered a well-tolerated substance with minimal estrogenic side effects;
  • Increased libido: there are anecdotal reports of improved sex drive and sexual function.

Nandrolone Phenylpropionate Side Effects

Nandrolone Phenylpropionate can cause the following side effects:

  • Testosterone suppression;
  • Water retention;
  • Hair thinning;
  • High blood pressure;
  • Acne and oily skin;
  • Aggression and paranoia;
  • Night sweats;
  • Virilization effects;
  • Cardiovascular issues.

NPP can cause intrusive thoughts, anxiety, aggression, obsessions, and toxic jealousy. It’s not recommended for individuals with severe mental health problems, as it can harm the progress they’ve made to cope with their issues.

Some users report relationship problems due to toxic jealousy and intrusive thoughts. It’s advisable to make sure that your partner is on board with this.

NPP for Women

Women can use Nandrolone Phenylpropionate in lower dosages, with a cycle length of 5–6 weeks. NPP can cause virilization effects, such as voice deepening or facial hair growth. To avoid permanent hormonal imbalance, it’s recommended to stop the cycle if any of the virilization effects occur.

It’s prohibited to take higher dosages of NPP or extend the cycle beyond 6 weeks, as it will result in virilization.

Nandrolone Phenylpropionate Dosage

The recommended dosage for men ranges between 100 and 700 mg per week, with a maximum cycle length of 10–12 weeks. The dosage for women can’t be higher than 50 mg per week, with a maximum cycle length of 6 weeks.

How to Take Nandrolone Phenylpropionate

Nandrolone Phenylpropionate should be injected intramuscularly. For men, it’s recommended to split the weekly dosage into 2 or 3 injections per week. Women can inject NPP once a week.

Even though NPP rarely causes an increase in estrogen levels, mostly at higher dosages, it’s recommended to add a dopamine receptor agonist to the cycle. Caber will help to prevent progestin levels from rising.

PCT is necessary since NPP is a potent anabolic steroid that will cause testosterone suppression. As with all side effects, if the dosage is high or the cycle length has been extended, suppression can be severe.

Common Questions About NPP

How Long Does Nandrolone Phenylpropionate Take to Kick In?

Peak NPP concentration levels in plasma can be seen as early as 24–48 hours after the first injection. As for the results, some notice first muscle gains a week after the cycle has started, some wait for 2–3 weeks. It’s individual.

Are NPP and Deca the Same Thing?

NPP, or Nandrolone Phenylpropionate, is called Deca, due to many similarities it shares with Deca Durabolin. It’s a different name for the same compound.

Can NPP Be Used for Cutting?

NPP can be used for cutting when stacked with different anabolic steroids, such as Winstrol.
