Precision-formulated for selective androgen receptor research. S4, also known as Andarine, is widely recognized as one of the earliest and most versatile Selective Androgen Receptor Modulators (SARMs) developed. Our 7.5mg formulation offers a precise, moderate concentration ideal for researchers looking to study the effects of selective anabolic activity without the volatility of higher initial concentrations.
Known for its exceptional tissue selectivity and high binding affinity (Ki = 4 nM), Andarine offers unique mechanistic insights into lean tissue preservation and skeletal integrity without the profound androgenic impact on secondary organs often observed with traditional compounds.
Key Research Applications
Lean Tissue Preservation: Extensively studied for its ability to maintain and protect skeletal muscle mass, particularly in research models simulating caloric deficits, cachexia, or degenerative wasting.
Bone Mineral Density (BMD): Investigated for its strong affinity to bone tissue androgen receptors, making it a primary compound of interest in osteoporosis and structural strength research.
Lipid Metabolism: Frequently observed in metabolic studies for its potential to stimulate lipolysis and enhance fat oxidation pathways alongside muscle retention.
Prostate Health Studies: Unique among SARMs, S-4 has been historically researched for its partial agonist properties in the prostate, offering distinct data points for BPH research.
Why Choose Our S-4 (Andarine)?
Optimized 7.5mg Dosing: Because S-4 is noted in pharmacokinetics literature for its relatively short half-life, this exact 7.5mg formulation allows for highly precise, multi-phasic dosing regimens in a controlled laboratory setting.
Uncompromising Purity: Synthesized in a state-of-the-art facility and subjected to strict third-party HPLC and mass spectrometry testing to guarantee ≥99% purity.
High Bioavailability: Engineered for maximum stability and consistent absorption, ensuring highly reproducible and reliable data across all your testing models.
