Ultimate Mass Stack – MK-677, LGD-4033, RAD-140 & YK-11 100mg Capsules

Ultimate Mass Stack – Research-Grade Protocol for Muscle Growth & Strength

The Ultimate Mass Stack is a high-potency research combination developed for controlled studies on lean muscle hypertrophy, strength, and recovery. Each capsule contains:

• 25mg Ibutamoren (MK-677)
• 25mg Ligandrol (LGD-4033)
• 25mg RAD-140 (Testolone)
• 25mg Myostine (YK-11)

This stack allows researchers to explore muscle growth, strength enhancement, recovery, and lean muscle preservation in laboratory settings.

Researchers use this stack to investigate:

• Muscle Growth & Hypertrophy – RAD-140, LGD-4033, and YK-11 are studied for their potential to increase lean mass and anabolic activity.
• Strength & Performance – LGD-4033 and RAD-140 help research improvements in power output, stamina, and performance metrics.
• Recovery & Growth Hormone Support – MK-677 may support tissue repair and stimulate growth hormone for enhanced lean mass research.
• Lean Muscle Preservation & Body Composition – YK-11 and RAD-140 may help maintain muscle while studying hypertrophy and body composition adaptations.

For extended research protocols, this stack can be combined with additional SARMs such as Ostarine (MK-2866), Cardarine (GW-501516), or Stenabolic (SR9009). Explore full Stacking Options for advanced research combinations.
