What is S23?
S23 is a new SARM from GTX, Inc. developed as a possible male hormonal contraceptive. It links to the androgen receptor (AR) more intensely (with a Ki of 1.7nM) as compared to older medicines such as Andarine.
In animal research, S23 displayed a good ratio of anabolic to androgenic effects as well as dose-dependent restraint of spermatogenesis (the course of sperm cell development) with unprompted recuperation after end of treatment.
Current Status: Under trial and investigation
As of today, what we know is that S23 is an easy-to-dose oral SARM that can boost lean muscle mass growth while being tissue selective at the same time. And it’s effects are said to be better than Andarine.
Where to Get S23 Online
For the longest time, S23 was very hard to find or buy anywhere online. However recently, MedFit RX came out with a product called Lucky SARMs that contain a total of 15mg S23 in every capsule!
