LGD-4033 Powder (Ligandrol)

A. Introduction

LGD-4033 (Ligandrol) is one of the most extensively documented compounds in the SARM category. Developed to address muscle wasting and osteoporosis, it is utilized by research institutions to study the selective activation of androgen receptors in bone and muscle tissues with significantly reduced impact on the prostate and sebaceous glands compared to traditional androgens.

B. Scientific Overview

Chemically identified as 4-((R)-2-((R)-2,2,2-trifluoro-1-hydroxyethyl)pyrrolidin-1-yl)-2-(trifluoromethyl)benzonitrile (C14​H12​F6​N2​O), LGD-4033 is a pyrrolidine-based ligand. In research settings, it is utilized to study the molecular mechanisms of myogenic differentiation and the up-regulation of anabolic gene expression. Its high binding affinity (Ki​ of ~1 nM) makes it an essential reference standard for comparative pharmacological analysis.
