Buy S-23 Powder For Research Use Only. Not Intended for Diagnostic or Therapeutic Use.
What is S-23 Powder?
S-23 is a highly potent, nonsteroidal selective androgen receptor modulator (SARM) designed to mimic the anabolic effects of testosterone with high selectivity for androgen receptors in muscle and bone tissue. This compound supports lean muscle mass growth, fat loss, enhanced endurance, and improved bone density, making it popular for research into muscle wasting, osteoporosis, and performance enhancement. S-23 powder is an orally bioavailable compound typically formulated for laboratory studies and research-only purposes. It is not approved for human or veterinary use.
