S-23 is arguably the strongest SARM to date. Think of it as a MUCH stronger version of S-4 with no vision side effects. It’s orally active, nonsteroidal, has a very high binding affinity for the androgen receptor. It can decrease prostate size, increase bone density, be used for bulking or cutting. It has almost unlimited potential, but PST (Post Sarm Therapy) should be done to keep what you’ve trained for. To demonstrate the safety of S-23, which proves the other SARMS to be mild in risk, know that a study was done and regardless of side effects, a baseline homeostasis was reached without any type of PST.
