S23 is an orally bioavailable, non-steroidal selective androgen receptor modulator (SARM) that has been proven to increase lean muscle and bone tissue while being tissue-selective (unlike traditional steroids).

Studies and user reports suggest that S23 is the closest SARM to steroids, with a few key differences, such as decreased prostate size. Other user reports suggest that S23 is a much more powerful version of S4 (Andarine) and the benefits of this SARM falls in the category of hardening muscle and creating a grainier aesthetic look.

Benefits have been shown to include:

  • increased endurance

  • increased muscle mass and strength

  • enhanced recovery

  • burns off excess fatty tissue

  • ability to run 8-12 weeks plus

  • increases bone strength

  • enhanced metabolic activity

  • lowers blood cholesterol

  • decreases inflammation 

  • can be stacked with anything

  • no side effects, liver toxicity, or suppression has been reported

  • can be used while cutting or bulking

  • uses body fat as as energy source

  • no research published has shown long term ramifications
