S23

90 Capsules

12mg Per Capsule

What is S23?

S23 is a potent investigational selective androgen receptor modulator (SARM) known for its strong binding affinity to androgen receptors. It is frequently studied for its potential to increase lean muscle mass, enhance strength, and aid in body recomposition. Due to its potency, S23 is typically explored in advanced performance and muscle-wasting research models.

Research Based Benefits

• May support research on significant lean muscle growth and strength
• Commonly used in studies on body fat reduction and muscle retention
• Could aid in understanding androgen receptor selectivity and anabolic action
• Useful in research involving high-affinity SARM interactions and muscle hypertrophy
• May contribute to studies on hormonal modulation and male contraception pathways
