ANDARINE S4

S4, also known as Andarine, is a selective androgen receptor modulator (SARM) renowned for its role in muscle growth, fat loss, and strength enhancement. Developed as a safer alternative to anabolic steroids, it exhibits high anabolic activity with minimal androgenic side effects, making it highly valuable in studies on performance, muscle preservation, and bone health.

• Lean Muscle Growth – Stimulates anabolic processes to support clean muscle mass gains
• Fat Reduction – Improves metabolic rate and decreases fat storage without compromising muscle
• Strength & Performance – Enhances physical output, power, and muscle endurance
• Bone Density Support – Promotes skeletal strength and resilience
• Minimal Side Effects – Liver-safe, non-aromatizing, and avoids major hormonal disruption

Selective Androgen Receptor Binding

• Targets muscle and bone tissue for focused anabolic activity

• Avoids unwanted effects on other organs

Anabolic Protein Synthesis

• Promotes muscle hypertrophy through increased nitrogen retention

• Aids in recovery and muscle maintenance during caloric deficits

Lipoprotein Lipase Reduction

• Inhibits fat storage enzymes to accelerate fat loss

• Helps achieve a lean, defined physique

Myostatin Inhibition

• Suppresses myostatin to unlock greater muscle-building potential

• Useful in long-term body recomposition research

Enhanced Vascularity & Density

• Reduces water retention

• Improves muscle definition and vascular appearance

Bone Health & Joint Support

• Enhances bone mineralization and joint integrity

• May reduce risk of injuries in high-stress training environments

• S4 (Andarine) is a potent research compound for studies on muscle growth, fat loss, and strength performance
•  Delivers powerful anabolic effects while supporting bone health and body recomposition
•  A safer research alternative to steroids with fewer side effects and superior selectivity
