Androgen 250 mg — Clinical & Pharmaceutical Reference Guide

Introduction

Androgen 250 mg from Genetic Labs is the most analytically authentic and widely trusted replica of the original Organon Sustanon 250® reference standard currently in production. Its precise 30/60/60/100 mg four-ester composition reproduces the exact tri-phasic release profile that has been the cornerstone of anti-doping science for decades. With purity consistently ≥ 99.7 %, original Genetic Labs holograms, and full ester-specific NMR and IRMS data, Androgen 250 mg remains the gold-standard material for longitudinal steroid profiling, T/E ratio monitoring, and exogenous testosterone confirmation worldwide. This guide provides detailed Androgen 250 mg information strictly within the legal framework of non-consumptive laboratory use.
