Avory Pharma Durabolin (NPP) 100 mg/ml — Clinical & Pharmaceutical Reference Guide

Introduction

Avory Pharma Durabolin 100 mg/ml is the most analytically trusted and widely used reference standard for the fast-acting phenylpropionate ester of nandrolone (NPP). With a half-life of only 4–6 days, it is the ideal model compound for studying intermediate-duration 19-nor exposure, early-phase 19-norandrosterone/19-noretiocholanolone kinetics, and detection windows of 4–8 weeks in urine. Its ultra-high purity (≥ 99.8 %), original Avory Pharma holograms, and comprehensive analytical package have made it the material of choice in over 45 WADA- and FEI-accredited laboratories worldwide.

FAQ Section

What is the exact name and ester? Nandrolone phenylpropionate (NPP) – fast-acting 19-nor steroid.

Is nandrolone phenylpropionate controlled? Yes – DEA Schedule III (U.S.), Class C (U.K.), prohibited by WADA/FEI worldwide.

How does it differ from Deca Durabolin? Shorter phenylpropionate ester = 4–6 day half-life vs 15 days for decanoate.

What is the shelf life? 60 months when stored at 15–30 °C protected from light.

Who may legally acquire Avory Pharma NPP 100? Only licensed forensic laboratories, university research departments, anti-doping agencies (WADA/FEI), and pharmaceutical companies with documented controlled-substance authorization.

**

Is it used in official anti-doping testing? Yes – it is the primary nandrolone phenylpropionate calibrant and quality-control material in virtually every WADA-accredited laboratory globally.
