S‑23 – 10mg

Permagainz S-23 is a high-purity non-steroidal Selective Androgen Receptor Modulator (SARM) supplied strictly for in-vitro and laboratory research.

This compound is widely studied in molecular pharmacology, receptor-binding analysis, and gene-expression research, where it serves as a model for examining androgen receptor (AR) selectivity, affinity, and signalling dynamics.

Each vial contains 10 mg of analytically verified S-23, produced in ISO-accredited clean-room facilities under Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) conditions to ensure reliability, purity, and batch-to-batch consistency.

Chemical Background / Research Profile

The chemical formula of S-23 is C₁₈H₁₃ClF₄N₂O₃, with a molecular weight of approximately 416.75 g/mol.

S-23 belongs to the aryl propionamide class of SARMs and is one of the most potent AR agonists within this category.
In controlled research environments, S-23 is used to:

• Investigate androgen receptor binding and transactivation.

• Examine ligand-receptor selectivity and partial vs full agonist behaviour.

• Explore receptor-mediated gene transcription and co-activator recruitment.

• Assess structure-activity relationships (SARs) across non-steroidal AR ligands.

Its high receptor affinity and strong anabolic-to-androgenic ratio make S-23 a reference compound in androgen receptor pharmacodynamics and molecular pathway analysis.

Purity and Quality Assurance

Permagainz S-23 is manufactured to ≥ 98 % purity, verified by High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS).

Every batch is issued with a Certificate of Analysis (CoA) detailing molecular structure, batch number, purity level, and expiry date.

All production and packaging take place under sterile, controlled laboratory conditions to preserve chemical integrity and analytical reproducibility.

Laboratory Handling and Storage

• Store at 20–25 °C in a dry, temperature-stable environment away from light and moisture.

• Use only analytical-grade solvents for reconstitution or dilution.

• Handle under aseptic conditions to avoid contamination.

• Prevent repeated freeze–thaw cycles.

• Dispose of all unused material according to institutional COSHH and chemical-waste safety procedures.

Researchers must use PPE (gloves, lab coat, and protective eyewear) and follow standard laboratory safety protocols.

Safety, Compliance and Restrictions

S-23 is not a pharmaceutical, not approved for human or veterinary use, and must not be consumed, injected, or used diagnostically or therapeutically.

It is supplied solely for scientific and in-vitro research.

Permagainz complies fully with MHRA, REACH, and COSHH regulations governing the lawful handling and supply of non-medicinal research materials.

All SARMs are batch-tested, documented, and traceable, ensuring full compliance and integrity within professional laboratory environments.

Through precision manufacturing, verified purity, and transparent documentation, Permagainz provides S-23 10 mg as a dependable research compound for studies into androgen receptor activation, molecular signalling, and receptor-ligand selectivity.
