What is S-23 Capsules?
S-23 is a potent, nonsteroidal selective androgen receptor modulator (SARM) developed to provide anabolic benefits similar to testosterone while minimizing side effects commonly associated with anabolic steroids. It exhibits high binding affinity and selectivity to androgen receptors primarily in muscle and bone tissue, promoting lean muscle mass gain, fat loss, and increased bone density. S-23 capsules provided by Next LVL Muscle contain research-grade S-23 intended strictly for laboratory scientific research and are not approved for human or veterinary consumption.
