S-23 Powder

Advanced androgen receptor research laboratories and qualified investigators studying potent selective androgen receptor modulators (SARMs), tissue-selective anabolic agents, and myotrophic compounds consistently select our S-23 powder as a high-specification, reliable research reagent. Supplied exclusively as S-23 powder for controlled in vitro, pharmacological, receptor-binding, muscle hypertrophy, prostate selectivity, pharmacokinetic, and analytical investigations, this non-steroidal arylpropionamide SARM is produced under strict quality protocols to support precise experimental reproducibility.

Superior Purity & Third-Party Verification

Our S-23 powder is synthesized to achieve ≥98% purity (often ≥99%), confirmed through orthogonal analytical methods including HPLC, LC-MS/MS, GC-MS, and NMR spectroscopy. Every batch undergoes independent third-party testing, with full Certificates of Analysis (CoA) provided that verify chemical identity, potency assay, residual solvent levels, moisture content, heavy metal screening, and microbial purity. This rigorous quality assurance ensures batch-to-batch consistency and clean, reproducible results in androgen receptor affinity assays, myotube differentiation studies, anabolic-to-androgenic ratio profiling, prostate vs. levator ani muscle selectivity comparisons, and reference standard preparation.

As one of the most potent non-steroidal SARMs characterized in preclinical models, S-23 exhibits high binding affinity to the androgen receptor, strong myotrophic activity, and significant suppression of endogenous testosterone, making it a valuable research tool for studying full androgenic effects, male contraception mechanisms, muscle wasting countermeasures, and structure-activity relationships in the arylpropionamide class.

Why Researchers Choose S-23 Powder

Investigators value S-23 powder for its:

• Exceptionally high anabolic potency and strong androgen receptor agonism in muscle tissue
• Utility in studying male hormonal contraception (due to spermatogenesis suppression), androgen deficiency models, sarcopenia, cachexia, and extreme myotrophic responses
• Distinct profile compared to milder SARMs (e.g., Ostarine, LGD-4033), offering research insights into full vs. partial androgen receptor activation
• Transparent CoA documentation, excellent batch consistency, and reliable solubility

“The potency and clean profiles of this S-23 powder delivered robust, dose-dependent myotube hypertrophy and clear suppression data in our androgen receptor studies – outstanding reagent.” – Androgen Pharmacology & Muscle Biology Research Group
