Select Androgen Receptor Modulators, or SARMs, are popular among people who want to get stronger and build muscle without the harsh side effects of steroids. SARMs help you gain muscle and lose fat, and they do this in a more targeted way. This article will explain the best SARMs for building lean muscle, how they work, their benefits, and how to use them safely. If you want to learn more about combining SARMs with other supplements for better results, check out our guide on SARMs stacks.
Key Takeaways
- Ostarine (MK-2866): Great for beginners, helps you keep muscle while losing fat.
- Ligandrol (LGD-4033): Strong SARM for more muscle mass, best for advanced users.
- Testolone (RAD-140): Powerful for muscle growth, used by experienced athletes.
- Andarine (S4): Good for fat loss and muscle definition.
- Cardarine (GW-501516): Helps with fat loss and boosts endurance.
SARMs are a safer option than steroids, but it’s still important to understand how they work and how to use them properly to get the best results.
What Are SARMs?
SARMs are special compounds that work by attaching to androgen receptors in your muscles and bones. When activated, these receptors help grow muscle and burn fat. They are similar to steroids but are more selective, meaning they mostly affect your muscles and bones, not other parts of your body.

Why SARMs Are Popular for Building Lean Muscle
- Help you grow lean muscle without gaining too much fat.
- Increase strength and endurance, making workouts easier.
- Speed up recovery after tough workouts.
- Help burn fat while keeping muscle.
Unlike steroids, SARMs don’t affect your heart, liver, or other organs as much. That’s why many people choose them for fitness goals. For more about how SARMs can help with endurance sports, take a look at this article.
How Do SARMs Work in the Body?
Selective Androgen Receptor Modulation
SARMs work by attaching to special receptors in muscle and bone cells. When these receptors are activated, your body grows muscle and burns fat. This is called “anabolism” (building muscle) and “lipolysis” (burning fat). Learn how combining SARMs with BCAAs can improve your muscle recovery and overall results.
Muscle Growth and Fat Loss
SARMs help your muscles grow by making them produce more protein. They also help burn fat, so you get a leaner, more defined look. They can also make your workouts feel easier by increasing endurance, so you can push yourself harder.
SARMs vs. Steroids
Steroids can affect your entire body, including your liver and heart, which can lead to dangerous side effects. SARMs are different because they only affect muscles and bones. This makes them safer, but they still have some side effects that you should be aware of.
The Best SARMs for Building Lean and Muscular Physique
Here are the best SARMs to help you build lean muscle and look shredded.
1. Ostarine (MK-2866)
Why Ostarine is Great for Beginners
Ostarine (MK-2866) is a mild SARM that is perfect for beginners. It helps you keep your muscle mass while losing fat, making it a good choice if you’re trying to get leaner without losing muscle.
Benefits of Ostarine
- Preserves muscle when you’re cutting (losing fat).
- Helps you recover faster after workouts.
- Increases strength and stamina.
Dosage and Cycle Length
- Dosage: 10-25mg daily.
- Cycle: 4-8 weeks.
Side Effects
Ostarine has few side effects, but it can slightly reduce your natural testosterone levels. Some people also report headaches or nausea at higher doses.
2. Ligandrol (LGD-4033)
Why Ligandrol is Effective for Bulking
Ligandrol is a stronger SARM that works well if you want to gain muscle fast. It’s perfect for people who have already tried SARMs before and are looking for bigger gains.
Benefits of Ligandrol
- Increases strength quickly.
- Builds lean muscle mass faster than Ostarine.
- Ideal for bulking (gaining muscle mass).
Dosage and Cycle Length
- Dosage: 5-10mg daily.
- Cycle: 8-12 weeks.
Side Effects
Ligandrol can suppress natural testosterone, so you may need Post Cycle Therapy (PCT) to help bring your hormones back to normal. Other side effects might include headaches or fatigue. For more on PCT, visit our PCT and Glutamine page.
3. Testolone (RAD-140)
Why RAD-140 is Popular for Big Gains
Testolone (RAD-140) is one of the most powerful SARMs available. It’s used by experienced bodybuilders who want maximum muscle growth and strength.
Benefits of RAD-140
- Major muscle growth.
- Improves endurance and recovery.
- Boosts strength for better workouts.
Dosage and Cycle Length
- Dosage: 10-20mg daily.
- Cycle: 6-8 weeks.
Side Effects
RAD-140 can suppress testosterone levels, leading to possible mood changes or aggression. It’s important to monitor side effects and consider using PCT after the cycle.
4. Andarine (S4)
Why Andarine Helps with Fat Loss and Muscle Retention
Andarine (S4) is a great choice if you’re looking to get shredded while keeping your muscle. It helps burn fat and keeps muscle, making it a good option for people in cutting phases.
Benefits of Andarine
- Burns fat while preserving muscle.
- Great for getting a defined, lean look.
- Increases strength and endurance.
Dosage and Cycle Length
- Dosage: 25-50mg daily.
- Cycle: 6-8 weeks.
Side Effects
One side effect of Andarine is that it can affect your vision, especially in low-light situations. If this happens, reducing the dose can help.
5. Cardarine (GW-501516)
Cardarine’s Role in Fat Loss and Endurance
Cardarine (GW-501516) is not technically a SARM, but it’s often used with SARMs to help burn fat and increase endurance. It’s great for people who want to improve their stamina and lose fat quickly. For more info on how Cardarine supports strength cutting, check this page.
Benefits of Cardarine
- Boosts endurance for longer workouts.
- Helps with fat loss.
- Works well when combined with other SARMs.
Dosage and Cycle Length
- Dosage: 10-20mg daily.
- Cycle: 8-12 weeks.
Safety and Side Effects
Cardarine is generally safe, but it’s important to buy from a trusted source to avoid impurities. It’s less likely to cause side effects compared to other SARMs.
Other SARMs and Supplements for Enhanced Physique
- S-23: A strong SARM for advanced users looking to gain muscle and lose fat at the same time.
- MK-677 (Ibutamoren): Not a SARM, but helps boost growth hormone levels, improving muscle recovery and fat loss.
- Creatine: A supplement that supports strength and muscle growth during SARMs cycles. For more, check out our strength athletes page.
How to Safely Use SARMs for Lean Muscle
Dosage and Cycle Length
- Beginners: Start with a low dose (e.g., 10mg/day for Ostarine) and increase gradually if needed.
- Advanced Users: Higher doses (up to 20mg/day for RAD-140) can be used, but always follow cycle guidelines.
Post-Cycle Therapy (PCT)
After finishing a cycle of SARMs like RAD-140 or Ligandrol, you might need Post-Cycle Therapy (PCT) to help bring your testosterone levels back to normal. This is important to keep your muscles and energy levels high after a cycle. For PCT support, check out our page on joint health and recovery tips.
Cycling SARMs
A typical SARM cycle lasts 6-12 weeks. After the cycle, take a 4-6 week break to give your body time to recover.
Maximizing Results with SARMs
Training Tips for Building Lean Muscle
- Focus on compound exercises like squats, deadlifts, and bench presses to work multiple muscle groups.
- Use progressive overload—gradually increase weights or reps over time to challenge your muscles.
Nutrition for Lean Muscle and Fat Loss
- Protein: Aim for about 1 gram of protein per pound of body weight to build muscle.
- Carbs: Eat enough carbs to fuel your workouts and keep your energy up.
- Fats: Include healthy fats (like avocado, nuts, and olive oil) to help your body produce hormones.
Supplements to Support SARMs
- Creatine: Helps improve strength and muscle growth.
- Whey Protein: Great for muscle repair after workouts.
- BCAAs: Helps with muscle recovery and reduces soreness.
