S-23

S-23 is a potent Selective Androgen Receptor Modulator (SARM) developed by GTX Inc. as part of their research into male contraceptives and treatments for muscle wasting disorders. Among all SARMs, S-23 is considered one of the most powerful, known for its extreme anabolic activity, lean muscle development, and fat reduction properties.

Due to its high androgen receptor binding affinity, S-23 is a popular compound in scientific research focusing on muscle hypertrophy, strength performance, and hormone regulation.

What is S-23?

S-23 is a non-steroidal SARM designed to selectively bind to androgen receptors in muscle and bone tissue. Unlike steroids, it does not convert to estrogen or DHT, making it a cleaner and more targeted compound for research.

What sets S-23 apart is its remarkably strong anabolic-to-androgenic ratio, making it ideal for research studies on muscle growth, fat loss, and hormonal balance.

Key Features

• Compound Name: S-23

• Category: Selective Androgen Receptor Modulator (SARM)

• Form: Oral (capsules or liquid solution)

• Half-Life: ~11–12 hours

• Legality: For research purposes only (not FDA-approved for human use)

Benefits of S-23 in Research

• 💪 Massive Lean Muscle Gains: Stronger anabolic effects than most SARMs.

• ⚡ Enhanced Strength: Rapid improvements in physical performance.

• 🔥 Fat Reduction: Supports fat oxidation while preserving lean muscle.

• 🧪 Hormone Regulation Studies: Investigated for use in male contraceptive research.

• 🦴 Bone Density Support: Potential role in osteoporosis research.

• 🚫 Non-Steroidal Alternative: Offers steroid-like benefits without harsh androgenic effects.

Potential Research Applications

• Male contraceptive trials

• Muscle wasting disorder studies

• Performance and strength research

• Bone density and osteoporosis support

• Fat metabolism studies

Possible Side Effects

As one of the strongest SARMs, S-23 may have more pronounced side effects than milder compounds:

• Testosterone suppression (post-cycle recovery required in studies)

• Potential aggression or mood swings (dose-related)

• Minor increases in liver enzymes (depending on research dosage)

• Possible effects on fertility in male contraceptive studies

⚠️ Strictly intended for laboratory and research use only.

Recommended Dosage (For Research Purposes Only)

• Dosage Range: 10–30 mg daily

• Cycle Duration: 6–8 weeks

• Half-Life: 11–12 hours (split dosing recommended)

• Stacking Options: Often combined with RAD-140, LGD-4033, or YK-11 in advanced hypertrophy research.

Storage Guidelines

• Store in a cool, dry location, away from sunlight.

• Keep tightly sealed to maintain potency.

• For laboratory research only.
