Avory Pharma Sustanon 300 mg/ml — Clinical & Pharmaceutical Reference Guide

Introduction

Avory Pharma Sustanon 300 mg/ml is currently the highest-quality, analytically purest high-concentration version of the classic 4-ester Sustanon blend manufactured under European GMP standards. Its exact Organon 36/72/72/120 mg ratio reproduces the original tri-phasic release profile while delivering 20 % more total testosterone than traditional 250 mg/ml formulations. With purity consistently ≥ 99.8 %, original Avory Pharma holograms, and full ester-specific NMR/IRMS characterization, it is the definitive reference material for modern anti-doping science, athlete biological passport research, and forensic identification of high-dose clandestine Sustanon products.
