The Best SARMs Stack for Muscle Growth (2025 Guide)

Maximise Lean Mass Gains with These Proven Combinations

Introduction

If you're serious about building lean muscle mass, you’ve likely come across SARMs (Selective Androgen Receptor Modulators). While SARMs can be effective on their own, stacking them can take your physique to the next level—as long as you choose the right combination.

In this article, we’ll break down the best SARMs stacks for muscle growth, how they work synergistically, and how to cycle them safely.

Why Stack SARMs?

Stacking SARMs means combining two or more compounds to amplify results. Each SARM has a unique mechanism of action. When properly combined, they can enhance:

  • Protein synthesis
  • Nitrogen retention
  • Muscle endurance and strength
  • Recovery and muscle fullness

The right stack can offer faster and more sustainable gains than single-compound cycles.

Top SARMs Stack for Muscle Growth

💪 Bulking Stack (Size & Strength)

Best for: Intermediate to advanced users looking for rapid size gains

  • RAD-140 (Testolone) – 10–20mg/day
  • LGD-4033 (Ligandrol) – 5–10mg/day
  • MK-677 (Ibutamoren) – 20–25mg/day

Cycle length: 8–12 weeks
PCT recommended: Yes (Clomid or Nolvadex)

Why it works:

  • RAD-140 boosts muscle mass and strength
  • LGD-4033 supports size and recovery
  • MK-677 stimulates GH and IGF-1, improving sleep, recovery, and lean mass retention

📈 Expect gains of 8–12 lbs of lean muscle when combined with proper nutrition and training.

🔥 Lean Muscle Stack (Clean Gains, Recomp)

Best for: Users wanting to build muscle with minimal fat gain

  • Ostarine (MK-2866) – 20–30mg/day
  • S4 (Andarine) – 25–50mg/day
  • Cardarine (GW-501516) – 10–20mg/day

Cycle length: 8 weeks
PCT required: Mild (depending on dosage)

Why it works:

  • Ostarine supports muscle gain while enhancing joint health
  • Andarine increases strength and vascularity
  • Cardarine improves endurance and fat metabolism

💡 Ideal for a lean, aesthetic physique with better pumps and muscle hardness.

🧪 Advanced Muscle Mass Stack

Best for: Experienced users aiming for maximum hypertrophy

  • YK-11 – 10mg/day
  • RAD-140 – 10mg/day
  • MK-677 – 25mg/day

Cycle length: 8–10 weeks
PCT required: Stronger protocol recommended

Why it works:

  • YK-11 inhibits myostatin, unlocking potential for extreme muscle growth
  • RAD-140 ensures androgenic support without conversion to estrogen
  • MK-677 increases appetite and growth hormone levels

⚠️ This stack is not for beginners and should be used with regular health monitoring.

Important Tips for Stacking SARMs

  • Start with a base SARM, like Ostarine or RAD-140
  • Introduce one compound at a time to assess tolerance
  • Use on-cycle support like liver protectants (especially for YK-11)
  • Have a solid PCT plan to restore testosterone and prevent suppression
  • Track your progress with body measurements, strength logs, and bloodwork
