Overview

S-23 is a type of chemical known as a selective androgen receptor modulator (SARM). It mimics the activity of testosterone in the body.

S-23 is banned by the World Anti-Doping Agency (WADA) and the National Collegiate Athletic Association (NCAA).

S-23 is used to increase energy, improve athletic performance, increase muscle growth, and for other uses, but there is no good scientific evidence to support its use. S-23 might also be unsafe.
