Like the most relevant sports pharmacology today, nandrolone phenylpropionate (NPP) was not originally produced for doping, but rather for medical use. It has been used for medical reasons ranging from asthenia (an asthenic condition or syndrome characterized by general weakness in the patient) to osteoporosis (a chronic progressive skeletal disease accompanied by a decrease in bone strength).

Despite its medical origin, the NPP steroid is currently most in demand as a sports dopant: it is widely used as a separate drug and as a component of mixtures.

What is Nandrolone Phenylpropionate?

NPP is one of the steroid esters of Nandrolone, active up to 4-8 days (half-life – 2-4 days) after application: compared to Nandrolone decanoate, the ester chain of the NPP is about half as long, which provides the fastest entry into the bloodstream, but limits the duration of action. As a doping drug, it is effectively used for muscle growth and general strengthening of the athlete’s body.

Side effects

When using NPP, side effects can be observed, but they are relatively rare. For example, the following complications are possible:

  • androgen – from acne to hair growth;
  • progestins: from libido disorders to gynecomastia induced by progestins;
  • estrogenic: from water retention in the body to estrogenic gynecomastia.

But if the recommendations are followed, they usually do not occur or are of a mild transient nature.

It is important!

One of the main advantages of NPP is precisely the optimal ratio between potency and safety: high anabolic and low androgenic activity, minimal aromatization, moderately weak progestogenic properties and no hepatotoxicity.

NPP course

The steroid has a wide spectrum of action, which makes it suitable for athletes of various sports. They are used by everyone, even bodybuilders who adhere to a variety of programs, including strength, as well as classes for gaining muscle mass and even drying. This ensures the drug’s ability to stimulate high-quality muscle growth without excess water and fat.

NPP course

NPP course

The average recommended dose of NPP is 100-200 mg every 2-3 days. In most cases, this is enough for the development of pronounced results without dangerous consequences. NPP for lasting action requires intensive introduction into the body, at least 2 times a week.

The average duration of the course is 8 weeks. Any longer it is generally not used due to the risk of androgenic, progestin and estrogenic side effects. It is important to understand that the effective doses, as well as the frequency and duration of use of NPPs, are chosen individually by the athlete.

For maximum progress, NPP is often combined with other medications. It goes well with testosterone, methandienone and other substances actively used by amateurs and professional athletes.
