Frequently Asked Questions

What is S23?

S23 is a nonsteroidal selective androgen receptor modulator widely described as one of the most potent SARMs studied. Unlike partial agonists such as S4 or LGD-4033, S23 acts as a full androgen-receptor agonist in research models.

How does S23 work?

S23 binds androgen receptors tightly (a Ki of approximately 1.7 nM) with full agonist activity and high oral bioavailability (up to ~96% in preclinical models). Research has explored its effects on protein synthesis, bone integrity, and hypothalamic-pituitary-gonadal axis feedback in animal subjects.

What is the half-life of S23?

S23 has an approximate half-life of around 12 hours in preclinical models, which typically leads researchers to divide daily doses into two or three administrations.

What does research note about S23?

Because of its full-agonist profile and potency, S23 is among the more suppressive SARMs studied, and its strong HPG-axis suppression has been examined in the context of male-contraceptive research in animals. It is an unapproved research chemical.

Is S23 sold for human use?

No. All products are supplied strictly for laboratory and research use only. They are not approved for human or veterinary use, diagnosis, treatment, or consumption.
