Androbol-300 mg — Clinical & Pharmaceutical Reference Guide

Introduction

Androbol-300 from Lyka Labs is one of the most analytically consistent and widely adopted multi-ester testosterone reference standards currently produced under Indian GMP and exported globally. By combining four classic esters in a 50/50/100/100 mg ratio, it delivers a characteristic tri-phasic release profile that closely mimics older European Sustanon-type formulations. With purity ≥ 99.6 %, original Lyka Labs holograms, and full ester-specific documentation, Androbol-300 is the material of choice in over 40 WADA-accredited laboratories for calibration of complex testosterone blends and athlete biological passport (ABP) studies). This guide provides comprehensive Androbol-300 information strictly within the legal framework of non-consumptive scientific use.
