PUMP (S-23) – High-Affinity SARM for Muscle Growth & Fat Loss
PUMP (S-23) is a potent, non-steroidal Selective Androgen Receptor Modulator (SARM) with high binding affinity to androgen receptors, making it stronger than MAINTAIN (MK-2866) and MASS (S-4). This high potency leads to rapid muscle growth, reduced fat mass, and potential prostate size reduction.
Studies indicate that PUMP (S-23) can support both bulking and cutting phases due to its ability to increase muscle mass while promoting fat loss. Additionally, research suggests potential male contraceptive properties, making it a versatile SARM for multiple applications.
How PUMP (S-23) Works
PUMP (S-23) is a research compound studied for its strong binding affinity to androgen receptors in muscle and bone tissue. This selective activity has made it a point of interest in research focused on lean muscle development, strength, and physique refinement, particularly in advanced recomposition and cutting protocols.
Key Benefits of PUMP (S-23)
Powerful Muscle Growth – Stronger than other SARMs, ideal for rapid lean muscle gains.Fat Reduction – Helps decrease body fat while preserving muscle.Enhanced Bone Density – Shown to increase bone mineral density, supporting joint and skeletal health.Potential Male Contraceptive Effects – Temporarily reduces LH & FSH levels, preventing sperm production.Versatile for Bulking & Cutting – Suitable for muscle-building cycles and fat-loss phases.
Why Choose PUMP (S-23)?
PUMP (S-23) is often chosen in advanced research settings for its reputation in supporting a harder, drier, and more defined physique. Its potent profile makes it a strong option for those exploring compounds linked to lean muscle retention, strength, and aggressive body recomposition outcomes.
Take your research to the next level with PUMP (S-23) – a powerful compound for lean muscle retention, physique hardness, and advanced recomposition support.
Recommended Combinations
- For Maximum Muscle Growth → Stack with MASS (S-4) or GAIN (LGD-4033) for enhanced strength and size.
- For Cutting & Recomposition → Pair with MAINTAIN (MK-2866) or SHRED (GW-0742) to maintain lean muscle while reducing fat.
- For Hormonal Recovery → Consider using a Post Cycle Therapy (PCT) protocol after research as this product is very potent.
- AUS LABS CUT STACK → Combines PUMP (S-23) with the potent fat burning and endurance benefits of SHRED (GW-0742) for our most popular fat loss stack.
