Intermediate Muscle Stack – RAD-140, LGD-4033 & MK-677 75mg Capsules

Intermediate Muscle Stack – Advanced Research Protocol for Muscle Growth & Strength

The Intermediate Muscle Stack is a research-grade combination designed for studies on enhanced muscle growth, strength improvement, and recovery protocols. Each capsule contains:

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

This stack allows researchers to conduct controlled studies on lean muscle development, strength enhancement, and recovery optimisation.

Researchers utilise this stack to investigate:

• Lean Muscle Development – RAD-140 and LGD-4033 are widely studied for hypertrophy and lean tissue gains.
• Strength & Performance – The combination helps explore improvements in muscular strength, endurance, and power output.
• Recovery & Growth Hormone Support – MK-677 may support faster recovery and stimulate growth hormone for enhanced lean mass research.

For expanded research protocols, this stack can be complemented with additional SARMs such as Stenabolic (SR9009), Cardarine (GW-501516), or S4 (Andarine) to study endurance, cutting, or more advanced muscle growth cycles. Check our Stacking Options for full experimental combinations.

Key Research Benefits

• Intermediate Muscle Growth Research – Combines three potent compounds for controlled studies on lean muscle and strength.
• Strength & Performance – Supports research into power output, stamina, and muscular performance.
• Recovery Support – MK-677 may aid recovery and lean mass development.
• Stack Expansion – Can be paired with S-23, S4, or Stenabolic for advanced experimental protocols.

Ingredients

• RAD-140 (Testolone) – 25mg per capsule
• LGD-4033 (Ligandrol) – 25mg per capsule
• MK-677 (Ibutamoren) – 25mg per capsule
• Capsule Shells – Composed of cellulose and purified water
• No Fillers or Additives – Pure lab-grade compounds for precise research outcomes

Recommended Post Cycle Therapy (PCT)

This stack may suppress natural testosterone production. A Post Cycle Therapy (PCT) protocol is recommended to maintain hormonal balance and support recovery. Using a dedicated cycle support supplement, such as SARMs Cycle Support, can help optimise outcomes after research cycles.
