Buy S-23 Powder – High-Purity Selective Androgen Receptor Modulator (SARM) for Research

Introduction

S-23 is a nonsteroidal SARM with a chemical formula C18H13ClF4N2O3 and a molar mass of 416.76 g/mol. It binds androgen receptors with a Ki of 1.7 nM, demonstrating higher affinity than many earlier SARMs such as andarine. In animal studies, S-23 increases muscle mass and strength while suppressing testicular sperm production, effects that reverse after treatment stops. These properties make it a promising candidate for male contraception research and muscle wasting therapies.

S-23 is orally bioavailable (~96%) with peak plasma levels reached approximately 4 hours post-administration and a half-life of about 12 hours, allowing for once or twice daily dosing in experimental protocols.

Key Features & Benefits

• High-purity white powder with ≥98% purity confirmed by HPLC and LC-MS.

• Strong selective androgen receptor binding (Ki = 1.7 nM) with potent anabolic effects.

• Demonstrates dose-dependent, reversible suppression of spermatogenesis in animal models.

• Promotes lean muscle growth, strength, and improved body composition.

• Oral bioavailability of approximately 96% with a half-life of ~12 hours.

• Useful for research into male hormonal contraception, muscle wasting, and androgen receptor modulation.

• Soluble in organic solvents such as DMSO, ethanol, and DMF for formulation flexibility.

• Discreet packaging and worldwide shipping available.

Product Specifications

Applications & Usage

S-23 powder is used in research to:

• Investigate selective androgen receptor modulation for muscle growth and strength.

• Study reversible male hormonal contraception via spermatogenesis suppression.

• Explore anabolic to androgenic activity ratios in vivo and in vitro.
