S-23 Injectable

Overview of S-23
S-23 is a synthetic non-steroidal selective androgen receptor modulator (SARM). It demonstrates high binding affinity to androgen receptors and is considered to be one of the most potent SARMs. Preclinical studies have specified its effects, which may include strong anabolic effects and maintenance of lean mass and bone density in research models.
Research suggests that S23 may preserve fast-twitch and slow-twitch muscle fibers under conditions of muscle-wasting stress. Its high anabolic-to-androgenic ratio enables research into muscle retention and receptor activity with limited prostate impact.

Frequently Asked Questions
Is S-23 Injectable legal?
As of now, S23 is not approved by the FDA for human or veterinary use. It is legally permitted only for laboratory or research purposes in the United States.
What is S23 used for in research?
S-23 has the potential for reversible suppression of reproductive functions. It is also studied for its ability to promote lean mass and bone density in research subjects.
What are the observed side effects of S23 Injectables in research models?
S-23 has been shown in preclinical studies to cause marked suppression of natural hormone production and shrinkage of reproductive tissues in research. It may also lead to behavioral changes, such as increased aggression in test models.
Is S-23 more potent than other SARMs?
S23 is considered more potent than most other SARMs. It shows stronger binding affinity to androgen receptors and greater anabolic activity compared to compounds like Ostarine, Ligandrol, and even RAD-140.
