S-23 SARM 25mg Capsules – Elite Lean Muscle & Fat Loss Research Compound

S-23 is a next-generation Selective Androgen Receptor Modulator (SARM) developed for advanced laboratory research into lean muscle hypertrophy, fat reduction, strength enhancement, and body recomposition.

Recognised as one of the most potent non-steroidal SARMs available, S-23 demonstrates an exceptionally strong binding affinity to androgen receptors, making it a prime research compound for studies focused on anabolic signalling, muscle protein synthesis, metabolic efficiency, and androgenic response.

Each capsule contains 25mg of pharmaceutical-grade S-23, manufactured under strict quality control standards to ensure consistent research integrity.

Research Overview

S-23 is widely studied for its ability to deliver strong anabolic activity while remaining tissue-selective. In controlled laboratory models, S-23 is researched for:

• Accelerated lean muscle development
• Increased strength and performance output
• Enhanced fat metabolism and recomposition
• Androgen receptor activation without steroidal structure

Its powerful androgen receptor affinity makes it ideal for advanced research protocols examining muscle physiology and metabolic adaptation.
