The Ultimate Guide to SARMs for Muscle Growth: Choosing the Right Compounds and Dosages

Selective Androgen Receptor Modulators (SARMs) have become increasingly popular among fitness enthusiasts and bodybuilders for their ability to enhance muscle growth, strength, and performance with fewer side effects than traditional anabolic steroids. SARMs target androgen receptors in muscle and bone tissues selectively, potentially offering muscle-building benefits without the severe side effects associated with steroids. However, it's crucial to choose the right SARMs and dosages to maximize muscle growth safely and effectively.

Key SARMs for Muscle Growth

  • RAD-140 (Testolone)

    Overview: RAD-140 is renowned for its potent anabolic effects. It's often compared to testosterone in its ability to increase muscle mass and strength.

    Benefits: Significant increases in muscle mass, improved strength, and enhanced endurance.

    Dosage: Typical dosages range from 10 to 20 mg per day. Beginners should start with 10 mg to assess tolerance, potentially increasing to 20 mg after 1-2 weeks.


  • LGD-4033 (Ligandrol)

    Overview: LGD-4033 is another highly effective SARM for bulking. It's known for its ability to promote substantial muscle growth and strength gains.

    Benefits: Rapid muscle mass gains, increased strength, and enhanced recovery.

    Dosage: Common dosages are between 5 to 10 mg per day. Beginners might start at 5 mg, while more experienced users may go up to 10 mg daily.


  • MK-677 (Ibutamoren)

    Overview: Although not a traditional SARM, MK-677 is a growth hormone secretagogue, meaning it stimulates the release of growth hormone. It's highly effective for muscle growth and fat loss.

    Benefits: Enhanced muscle growth, improved sleep quality, increased appetite, and better overall recovery.

    Dosage: Typical dosages range from 10 to 25 mg per day. For muscle growth, 20 to 25 mg per day is recommended.


  • YK-11

    Overview: YK-11 is a myostatin inhibitor, making it one of the most powerful compounds for muscle growth. It works by inhibiting myostatin, a protein that limits muscle growth.

    Benefits: Exceptional muscle mass gains, improved muscle density, and strength.

    Dosage: Recommended dosages are between 5 to 15 mg per day. Starting at 5 mg is advisable to assess tolerance.


  • Ostarine (MK-2866)

    Overview: Ostarine is well-known for its versatility and mild nature. It's effective for both bulking and cutting phases.

    Benefits: Lean muscle gains, improved strength, and better endurance.

    Dosage: Common dosages are 10 to 25 mg per day. Beginners should start at 10 mg, with more experienced users possibly increasing to 25 mg.


Combining SARMs for Synergistic Effects

Combining SARMs, also known as stacking, can enhance their effects for ultimate muscle growth. Here are a few popular stacks:


  • RAD-140 + MK-677:

    Benefits: This combination provides the powerful muscle-building effects of RAD-140 with the growth hormone-boosting benefits of MK-677. Expect significant muscle gains and improved recovery.

    Dosage: 10-20 mg of RAD-140 and 20-25 mg of MK-677 per day


  • LGD-4033 + YK-11:

    Benefits: LGD-4033's potent anabolic properties, combined with YK-11's myostatin inhibition, result in rapid and substantial muscle growth.

    Dosage: 5-10 mg of LGD-4033 and 5-10 mg of YK-11 per day.


Cycle Duration and Post Cycle Therapy (PCT)

Cycle Duration: Typical SARMs cycles last between 8 to 12 weeks. Shorter cycles may not provide maximum benefits, while longer cycles increase the risk of side effects.

Post Cycle Therapy (PCT): PCT is crucial after completing a SARMs cycle to help restore natural hormone levels and maintain the muscle gains achieved.  A typical PCT lasts 4 weeks.

Safety Considerations and Side Effects

While SARMs are generally considered safer than anabolic steroids, they are not without risks. Potential side effects include testosterone suppression, liver toxicity (especially with higher doses or longer cycles), and cardiovascular issues. Regular blood work and monitoring are recommended to ensure safety. It's also crucial to purchase SARMs from reputable sources to avoid counterfeit or contaminated products.


SARMs can be a powerful tool for achieving significant muscle growth and improving athletic performance. Choosing the right SARMs and dosages, as well as following proper cycle protocols and PCT, is essential for maximizing benefits and minimizing risks. Always consult with a healthcare professional before starting any new supplement regimen, and prioritize safety to achieve your muscle-building goals effectively.
