S4 (Andarine 25 mg)
S4 (Andarine) is a selective androgen receptor modulator (SARM) known for promoting lean muscle growth, increasing strength, and improving overall muscle definition. It is especially popular during cutting and recomposition phases due to its ability to enhance hardness and support fat reduction while preserving muscle mass.
Scientific Overview
Andarine works by selectively binding to androgen receptors in muscle and bone tissue, stimulating anabolic activity and increasing protein synthesis. It promotes nutrient partitioning, improves muscular density, and supports a clean, aesthetic physique without water retention.
Mechanism of Action
- Selective binding to androgen receptors
- Enhances protein synthesis and muscle hardness
- Improves nutrient partitioning and fat utilization
- Supports lean muscle preservation during caloric deficit
Purpose / Indications
- Improves muscle definition and hardness
- Enhances strength and performance
- Supports fat loss while maintaining lean mass
- Suitable for cutting and recomposition cycles
Key Benefits
- Dry, hard, and dense muscle appearance
- Improved strength levels
- Enhanced vascularity and aesthetic conditioning
- Minimal water retention
