NPP 100 (Nandrolone Phenylpropionate) – Overview

NPP 100 commonly refers to nandrolone phenylpropionate at a concentration of 100 mg/mL. Nandrolone phenylpropionate is an anabolic–androgenic steroid (AAS) derived from testosterone. It is a shorter-acting ester of nandrolone, meaning it releases the active hormone more rapidly compared to longer esters such as nandrolone decanoate.

Nandrolone itself is structurally modified from testosterone by the removal of a carbon atom at the 19th position (hence the term “19-nor” compound). This modification alters its anabolic and androgenic activity profile.

Pharmacological Characteristics

• Base Compound: Nandrolone

• Ester: Phenylpropionate (shorter-acting)

• Aromatization: Converts to estrogen at a lower rate than testosterone

• Progestogenic Activity: Present

The phenylpropionate ester allows for a faster onset and shorter duration of action compared to longer nandrolone esters. Like other anabolic steroids, nandrolone influences protein synthesis, nitrogen retention, and red blood cell production.

Potential Risks and Considerations

Use of nandrolone phenylpropionate may be associated with:

• Suppression of natural testosterone production

• Hormonal imbalance

• Adverse changes in cholesterol levels

• Increased cardiovascular strain

• Water retention (due to estrogenic activity)

• Progestogenic-related side effects

• Reduced libido or sexual dysfunction in some cases

As with other anabolic–androgenic steroids, long-term use may increase cardiovascular, endocrine, and psychological health risks.
