RAD-140 powder (Testolone)

A. Introduction

RAD-140 (Testolone) is one of the most widely studied compounds in the SARM category. Developed to overcome the limitations of traditional anabolic steroids, it is utilized by research institutions to investigate selective activation of androgen receptors in bone and muscle tissues while minimizing activity in androgenic organs.

B. Scientific Overview

Chemically identified as 2-chloro-4-[[(1R,2S)-1-[5-(4-cyanophenyl)-1,3,4-oxadiazol-2-yl]-2-hydroxypropyl]amino]-3-methylbenzonitrile ($C_{20}H_{16}ClN_{5}O_{2}$), RAD-140 is a substituted benzonitrile. In research settings, it is utilized to study the molecular mechanisms of protein synthesis and its potential neuroprotective effects against excitotoxic insults. Its high affinity for the androgen receptor ($K_i$ of ~7 nM) makes it a primary focal point for Structure-Activity Relationship (SAR) mapping.
