Nandrolone Phenylpropionate 100 is used in power sports for increased strength, improved body definition and stronger immune system during precompetitive training. Its best features are its high effectiveness and low chances of manifesting side effects.

  • Usage: Inject 300-800mg once a week
  • Cycle Duration: 8-10 weeks for optimal results 
  • Aromatization: No, but may increase prolactin level and cause gynecomastia. So, use with Caber. 0.5-1 mg twice a week, 8-10 weeks
  • Post Cycle Therapy: Clomid 100mg/day for 2 weeks, then 50mg/day for another 2 weeks
  • Stack With: Tbol/Winstrol 50mg/day or Testosterone Propionate/Masteron 100mg each other day

Novo-Pharm Durabolin NPP Administration and Dosage

Novo-Pharm NPP is characterized by the active substance's short half-life, which is why the injections should be made frequently – at least twice a week. Most injections are made intramuscularly every 3-4 days. For a single administration, the optimal steroid dose is 150-200 mg. The total weekly dose should be no more than 300-400 mg. 

Clomiphene citrate should be used for PCT 3-5 days after the end of the solo cycle. Using tamoxifen for post-cycle therapy is full of negative side reactions as it increases progestin activity, leading to flaccid erection, gynecomastia, and other adverse symptoms.

Novo-Pharm Durabolin NPP Combined Cycles

A variety of anabolic steroids can be combined with nandrolone phenylpropionate; up to 3 drugs can be used simultaneously during a cycle. NPP creates a synergistic effect in combination with other steroids in which drugs enhance each other's positive effects. Here are some examples of combined cycles:

NPP + Turinabol + Winstrol

  • 300 mg of Nandrolone injected weekly
  • 50 mg of Turinabol daily 
  • 40 mg of Winstrol injected daily

NPP + Masteron + Testosterone Propionate

  • 250 mg of drostanolone enanthate injected weekly,
  • 50 mg of testosterone propionate daily
  • 300 mg of nandrolone phenylpropionate weekly.

NPP + Testosterone Propionate + Winstrol

  • 300 mg of Nandrolone injected weekly,
  • 50 mg of testosterone propionate daily
  • 40 mg of Winstrol injected daily.

It is advised that multiple oral steroids are avoided in a combined cycle as this enhances the toxic effect on the liver. If the cycle length reaches 4-5 weeks, patients must add testosterone (propionate, enanthate) while decreasing other steroids' maximum dosages.

Novo-Pharm Durabolin NPP Benefits

The ester chain of NPP is twice shorter than decanoate, resulting in the active component entering the bloodstream quickly and starting its action rapidly. This creates some of the benefits of the drug:

  • the short half-life reduces the risk of adverse reactions;
  • in cases of manifestation of side effects or poor tolerance to the drug cycle, it is possible to stop the injections and remedy the situation without additional drugs.

The primary disadvantage of the drug is its need for frequent injections, but compared to shorter esters, this is not a significant downside. Nandrolone phenylpropionate metabolites are excreted from the body for a long time – traces of using the anabolic steroid can be detected 18-24 months after the cycle is completed, which is why competing athletes do not use the drug. 

The main positive aspects of NPP’s usage are the following:

  • More muscle mass. Phenylpropionate stimulates the synthesis of proteins and produces the right balance of nitrogen. The medicine decreases cellular protein degradation, which enables the most desirable muscle growth conditions.
  • Low fluid retention – water plays the part of the joint fluid (natural joint lubricant) in this particular case.
  • Increased amino acid absorption.
  • Stimulated secretion of collagen and storage of calcium in the body, increasing bone density.
  • Reduced joint and ligament pain, improved joint mobility. The steroid is recommended for athletes who subject their locomotive systems to heavy loads.

Phenylpropionate's effects are very similar to those of Decanoate, as both drugs are Nandrolone derivatives that vary only in their duration of action. Nandrolone is not a potent androgen, so there’s no acne, oily skin, excessive body hair growth or baldness. Phenylpropionate is less likely to cause side effects compared to testosterone and other androgenic substances.

On average, a single nandrolone phenylpropionate solo cycle can result in significant muscle volume increases; muscles are well-defined and lean without excess water or fat deposits. The drug affects the improvement of the physical abilities of the athlete – a standard cycle results in a 15 percent increase in strength. Nandrolone increases the amount of red blood cells in the body and stimulates the saturation of muscle fibers at 100% with oxygen, nitrogen and other nutrients. It promotes protein synthesis and its absorption; NPP produces several times faster protein assimilation.

Novo-Pharm Durabolin NPP Possible Side Effects

Novo-Pharm Nandrolone has a slight tendency to aromatize, while an increase in prolactin concentration in the body causes adverse reactions: prolactin gynecomastia (its signs do not cause itching in the nipple area, but tissue swelling and lump formation), reduced sexual vigor, decreased libido during the process, flaccid erection. Special drugs that reduce the concentration of prolactin such as Cabergoline (Dostinex) or Bromocriptine can eliminate the negative reactions. Nandrolone suppresses the body's endogenous testosterone secretion and inhibits gonadotropin production, resulting in prolonged post-cycle recovery processes.

Novo-Pharm Durabolin NPP

NPP (Durabolin, the popular sports drug) is an anabolic androgenic steroid with nandrolone phenylpropionate as its active agent. The active agent is noteworthy in contrast to nandrolone decanoate or "Deca" due to its short half-life of 2-4 days (when compared to Deca’s 7-10 days). Phenylpropionate produces slight retention of fluid and is better than nandrolone decanoate in combination with androgenic drugs. Bodybuilders, weightlifters, powerlifters and other athletes use the drug mainly to gain muscle mass and enhance strength.
