Androbol-300 mg — Clinical & Pharmaceutical Reference Guide

Introduction

Androbol-300 from Lyka Labs stands as one of the most analytically robust and highest-concentration multi-ester testosterone reference standards currently produced under Indian GMP and exported globally. Its precisely balanced 50/50/100/100 mg ester composition creates a distinctive tri-phasic pharmacokinetic profile widely used to model real-world clandestine Sustanon-type preparations. The combination of exceptional purity (≥ 99.6 %), batch-to-batch ester ratio reproducibility <1 %, and comprehensive analytical data package has made Androbol-300 indispensable in modern anti-doping science, forensic toxicology, and longitudinal steroid profiling research. This guide provides detailed Androbol-300 information strictly within the legal framework of non-consumptive laboratory use.
