MASS (S4) – Potent SARM for Strength, Lean Muscle & Fat Loss
MASS (S4), also known as Andarine, is a highly potent Selective Androgen Receptor Modulator (SARM) designed to promote lean muscle retention, fat reduction, and enhanced vascularity. It functions as a partial agonist of androgen receptors, allowing it to provide muscle-building benefits without the negative side effects associated with traditional anabolic steroids.
Unlike testosterone and steroids, MASS (S4) does not exhibit androgenic activity in non-skeletal muscles, meaning it has minimal impact on the prostate, hairline, or other hormone-sensitive tissues. Its powerful anabolic properties make it an excellent choice for cutting, recomposition, and strength enhancement.
How MASS (S4) Works
MASS (S4) is a research compound studied for its selective interaction with androgen receptors in muscle and bone tissue. This targeted activity has made it a popular focus in research involving lean muscle support, strength, and physique refinement, particularly during cutting and recomposition protocols.
Key Benefits of MASS (S4)
Lean Muscle Retention – Prevents muscle loss while in a caloric deficit.Fat Burning Support – Enhances metabolic rate and promotes fat elimination.Strength & Vascularity – Increases power output and produces a harder, more defined look.Minimal Side Effects – Unlike traditional steroids, does not impact non-skeletal muscle tissues.Orally Active – Convenient dosing with no injections required.
Why Choose MASS (S4)?
MASS (S4) is often chosen in research settings for its reputation in supporting lean muscle retention, improved definition, and a harder overall physique. Its balanced profile makes it a strong option for those exploring compounds linked to body recomposition and performance-focused outcomes.
Take your research to the next level with MASS (S4) – a versatile compound for lean muscle support, strength, and physique refinement.
Recommended Combinations
- For Endurance & Performance → Stack with MELT (SR-9011) at 20mg/day to boost stamina and energy.
- For Cutting & Fat Loss → MASS (S4) + MELT (SR-9011) (20mg/day) = A highly effective cutting stack.
- As Part of a Steroid Cycle → MASS (S4) enhances strength and lean muscle mass when stacked with an anabolic steroid cycle.
- As a Standalone Compound → MASS (S4) at 50mg/day can increase strength and lean muscle rapidly with noticeable improvements in 1-2 weeks.
- For Lean Gains & Fat Loss → Combine MASS (S4) + SHRED (GW-0742) + GAIN (LGD-4033) for lean muscle and fat loss simultaneously.
