NPP 100

What is NPP 100?

It is an anabolic steroid which is a synthetic androgen and is an agonist of the androgen receptor such as testosterone and dihydrotestosterone with long-term action in the body. Another well-known form of this steroid compound is nandrolone decanoate, also known as deca-durabolin, but these are different drugs.

It has strong anabolic and mild androgenic effects, thus has few and low likelihood of side effects, plus it is suitable for use by women.

This drug is often used by athletes and bodybuilders to increase body size, accelerate weight gain, and improve power and endurance, especially during cutting cycles.

Another way to use it is to preserve as much muscle tissue as possible during the period of weight loss. In this case, the substances are often combined with Testosterone Propionate for better effectiveness.


  • Classification: Anabolic Steroid
  • Active Half-life: 2-3 days
  • Dosage: 100-300mg EOD
  • Water Retention: No
  • Aromatization: Low

NPP Benefits

The substance is widely popular for its many beneficial effects when used to enhance performance. Plus, this compound has excellent therapeutic effects, making NPP a versatile quality steroid suitable for a wide variety of users and purposes.

It is used by athletes for mass gaining, cutting and general athletic purposes - this makes it a very versatile steroid that is often combined with other drugs for more specific purposes.

NPP 100 provides such effects:

  • Expressed muscle growth - after completing one cycle, you can gain up to 8 kg of muscle mass with minimal rollback phenomenon
  • Strengthens bones and ligaments - it stimulates collagen synthesis
  • Maintaining the gained amount of muscles while losing weight
  • Increasing endurance
  • Elimination of joint pain - by increasing the production of joint lubricant
  • Increasing the body's immune defenses
  • Conversion to estradiol (the main and most active female sex hormone) without aromatase enzyme

The drug is not very androgenic and is slightly more anabolic than testosterone. It is these benefits that essentially set it apart from the Test and made it popular in bodybuilding. It is also great for supporting the immune system, and is sometimes even used to relieve joint pain.

It works well with other steroids, usually short esters. For example, a good cycle for bulking might be a classic NPP cycle (300 m /week for 10 weeks), and one of the Testosterone esters (300 mg/week for 10 weeks). Be sure to also use aromatase inhibitors on PCT after the end of the cycle.

NPP Dosage

The drug is injected into the muscle. Use 22g-25g syringes with needle 1-1.5 inch long for intramuscular injections. The standard dosage is 200-400 mg per week. The duration of action of the drug is 2-3 days, therefore, it should be administered 1 time for 2-3 days to maintain the desired concentration in the blood.

The optimal dosage is 300 mg once a week, which provides good results for beginners and even some intermediate users who are re-cycling. However, more experienced users will need to take a larger amount, for example 250 mg 2 times a week (500 mg a week in general).

PCT is obligatory after going through a steroid cycle to maintain results and prevent possible side effects. When using NPP 100, it is recommended to take Clomid in the last week of the cycle and continue using it for another 3-4 weeks, which helps to restore testosterone levels in the body. It is worth taking 50-100 mg per day, gradually reducing the dosage.

During PCT, you can also take testosterone boosters and sports supplements such as protein, creatine, vitamins and mineral complexes, amino acids, BCAA.

It is not recommended to use Tamoxifen on PCT and combine with other progestins like Trenbolone or Anadrol.

NPP Cycles:

This drug is used both to preserve as much muscle tissue as possible while losing weight, and to gradually build up lean tissue, and to reduce mass while maintaining speed and strength.

A NPP cycle lasts from 4 to 12 weeks, and is often combined with other drugs for better efficacy and avoiding unwanted side effects. For example:

  • For maximum benefit, take a muscle-building supplement and an appropriate diet.
  • It is often recommended for use with Testosterone or Sustanon to avoid the progestin-only effects and the effects of low testosterone (low libido, weak erection).
  • To suppress the production of prolactin and reduce progestin activity, Winstrol can be used from the second to the last week.
  • To eliminate progesterone activity, it is necessary to include Bromocriptine or Cabergoline, also starting with the second and ending 2-3 weeks after the final injection of NPP.

The most optimal combined cycle:

  • Its duration is 8-12 weeks.
  • 100-300 mg NPP per week
  • 500 mg Testosterone Enanthate or Cypionate, or 500 mg Sustanon or Omnadren per week
  • 1 tablet of Cabergoline and aromatase inhibitors

Posible Side Effects and How to Avoid Them

If used the drug correctly and follow proper cycle duration - everything will be fine, otherwise:

  • The drug can cause a drop in testosterone level, which can also lead to a decrease in libido. 
  • Increased progestin activity can cause sex drive suppression or gynecomastia.

These effects can occur only with incorrect dosages. If you use the necessary amount, you will not experience them. Use Cabergoline for prevention, it helps you increase your sex drive during your cycle and shorten your recovery time between intercycle.

In addition to reducing dosages and shortening periods of use, the use of certain adjuvant agents, such as aromatase blockers or receptor blockers, can be included to help minimize or prevent the likelihood of the aforementioned effects occurring and provide a more tolerable experience.

  • To avoid the progestin - only effects and the consequences of low testosterone, it is recommended to combine predominantly substances with Testosterone.
  • The standard dose of NPP is 200-300 mg or more (400mg) per week, but it is recommended to start the cycle with small dosages. If you need to increase them, then do it gradually. Maximum 600 mg per week. In such a case, it is recommended to perform 2 cycles at intervals at reasonable doses, rather than one at high doses.
  • With long cycles (8 weeks and more), the use of chorionic gonadotropin is necessary. If you have not used HCG during your cycle, then it will need to be taken at the end of the cycle before PCT.
  • To suppress the production of prolactin and reduce progestin activity, use Winstrol from the second to the last week of the cycle.

Popular NPP Q&A

Does the substance raise blood pressure?

An increase in blood pressure occurs when the water retention effect in the muscles is not controlled. Substance may cause water retention, but only very slightly. If you do experience this effect, then use aromatase inhibitors to prevent it. This side effect of steroids is quite easily eliminated with 50 mg of Metoprolol and 5 mg of Enalapril.

Does NРР cause hair loss?

The drug can cause minimal androgenic effects. Compared to other steroids, it has a fairly low likelihood of their occurrence.

Hair loss usually occurs in those who have a genetic predisposition to it. That is, if none of your family has had baldness, then you have nothing to worry about. If this effect does occur, use Finasteride to get rid of it.

Are NPP and Deca-Durabolin the same thing?

NРР and Deca-Durabolin are two drugs that are nandrolone steroids. Phenylpropionate is the ester used in NPP, nandrolone decanoate is used in Deca-Durabolin.

In fact, it is almost the same as the steroid nandrolone in NPP, but a different ester is used in Deca.
