Buy S-23 Capsules

A. Introduction

S-23 is a specialized compound within the SARM category, utilized by research institutions to investigate tissue-selective activation of androgen receptors. Originally developed to explore applications in hormonal regulation, it serves as a critical reference standard for laboratories studying the molecular dynamics of protein synthesis and bone mineral density in cellular models.

B. Scientific Overview

Chemically identified as (S)-3-(4-chloro-3-fluorophenoxy)-N-(4-cyano-3-(trifluoromethyl)phenyl)-2-hydroxy-2-methylpropanamide ($C_{18}H_{13}ClF_{4}N_{2}O_{3}$), S-23 is a substituted propanamide. In research settings, it is utilized to study the suppression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) through negative feedback loops. Researchers focus on its exceptionally high binding affinity and its ability to promote anabolic gene expression while maintaining high selectivity.
