While SARMs themselves are not FDA-approved, several legal and natural alternatives offer comparable benefits using plant-based or nutrient-rich ingredients. These alternatives support muscle growth, improve stamina, aid in recovery, and may enhance libido.

This guide highlights the best SARMs and safe alternatives available in 2025, helping you choose the right supplement based on your specific fitness goals.

What are SARMs?

SARMs are Selective Androgen Receptor Modulators, which are similar to steroids in that they bind to androgen receptors and modify your DNA to build muscle mass and strength.

However, SARMs impact your muscles only, while steroids may also affect other tissue in the body. Thus SARMs avoid some of the side effects associated with steroid use.

Although currently SARMs pills are not approved for use anywhere in the world, there are a number of companies that sell legal, safe alternatives which are low risk.

Taking these can build muscles, raise libido, and promote fat and weight loss. For those who dislike capsules, there are also liquid SARMs available.

What are the Best-Known SARMs?

Here are some of the most popular SARMs from Crazy Bulk known for muscle building, fat loss, and performance:

Ostarine (MK 2866): Originally developed for muscle wasting and osteoporosis, this non-steroidal SARM helps increase lean muscle mass without significant weight gain. Side effects are generally mild—such as nausea, fatigue, or back pain.

Ligandrol (LGD 4033): Highly bioavailable, LGD 4033 supports muscle growth, improves recovery, and enhances performance. The typical dosage ranges from 5–10 mg daily for 6 to 10 weeks. Most users report noticeable gains with minimal side effects.

Ibutamoren (MK 677): Though not a true SARM, MK 677 stimulates HGH by targeting ghrelin receptors. It supports muscle growth, may suppress appetite, and can even help with low libido. Side effects include increased appetite and mild swelling.

Cardarine (GW 501516): Cardarine can enhance exercise endurance and boost energy, as well as speed up the metabolism for fat burning. It apparently can lead to great weight loss, and reviewers say the Cardarine before and after is very impressive.

Stenabolic (SR9009): Originally a research compound, it’s now widely used for its fat-burning and endurance-enhancing effects. It may also support better blood sugar control and metabolism regulation.

Testolone RAD 140: Mimics testosterone to promote muscle mass, strength, and stamina. It’s also said to boost sexual arousal. Available in capsule and liquid forms, though high doses may pose liver risks.

Science behind SARMs

The SARMs cycle works by binding to androgen receptors, specifically, in the muscles. Unlike steroids, they do not have an effect on other bodily tissue. They make slight modifications in the DNA, and according to U.S Pharmacist this leads to a state of anabolism, meaning bigger muscle growth and an improvement in bulking and cutting.^[1]

Types SARMs also have fat-burning and weight-loss benefits, can enhance exercise endurance, and improve exercise recovery. They may raise testosterone levels, which can lead to an increase in sexual libido and an improvement in sexual stamina.

Research in the Journal of Pharmacology and Experimental Therapeutics concluded that SARMs enhance female sexual motivation.^[2]

Many of the strongest SARMs for muscle growth include additional ingredients and may be high in anti-inflammatory agents which reduce swelling in the muscles and antioxidants which repair damage. Antioxidants destroy free radicals in your system, boost oxidative stress, and can strengthen the immune system.

Ingredients in SARMs

Many SARMs supplement products include additional organic ingredients to boost the benefits. Here are some of the primary active ingredients you may find:

Choline

Choline is a vital nutrient found in foods like red meat and eggs. It supports brain function, mood, memory, and muscle control, and helps form cell membranes. It may also boost calcium absorption for better muscle contraction. An article in Nutrients discussed the crucial role choline plays as an essential nutrient for skeletal muscle ^[3].

Alpha Lipoic Acid

Alpha-lipoic acid (ALA) is a natural compound that helps convert sugar into energy and acts as a strong antioxidant. It supports blood sugar control, boosts immunity, repairs muscles, enhances strength, and improves workout endurance. A study in the Journal of the International Society of Sports Nutrition concluded that ALA may reduce muscle damage and inflammation as well as improve recovery ^[4].

Beetroot

Beetroot is a superfood that supports heart health and may lower blood pressure and blood sugar. It can boost oxygen flow to muscles, aiding growth and possibly improving exercise endurance. A study in Nitric Oxide showed that high doses of beetroot improved the performance of professional cyclists ^[5].

Vitamin C

Vitamin C, found in berries and cruciferous veggies, is a strong antioxidant that supports cell growth, muscle and cartilage formation, and immunity. It may also help retain muscle mass with age and aid muscle repair. A study in the International Journal of Sports Nutrition Exercise Metabolism found that Vitamin C supplementation reduced muscle soreness and oxidative stress ^[6].

Caffeine Anhydrous

Caffeine anhydrous is a potent form of caffeine that boosts metabolism and promotes fat burning. It increases energy, supports weight loss, improves focus, and enhances workout endurance. It’s often found in SARMs for fat loss. A literature review in the Journal of the International Society of Sports Nutrition concludes that caffeine may improve muscle strength and power ^[7].

How Do You Choose the Best SARMs?

Selecting the best SARMs for you should largely be based on your goal and the product that best meets that goal. I have explained the benefits and merits of each of the primary SARMs and suggested several amazing legal, natural alternatives. When searching online for SARMs for sale or legal alternatives, there are some things you should keep in mind:

Manufacturer: Buy your product from a well-known and trusted brand that makes quality products. If the company has a good reputation, this makes it more likely that the product will be a high-level formula.

Safety and Ingredients: Check all of the ingredients to make sure there are no potentially harmful additives or fillers. In addition, read up about the company’s safety practices. Ideally, they should do their manufacturing in an FDA-regulated facility following GMP standards.

Price: As the prices of these products can vary quite widely, do a price comparison before you buy and pay attention to the value of the product for the listed cost. Sometimes for a quality brand, it’s worth paying a little more.

Customer Reviews: Customer feedback is always a goldmine in terms of finding out the pros and cons of a particular product. If there’s a brand that interests you, read through all of the user’s comments you can find to get an idea of the customer experience.

Return Policy: You may try a supplement and find that it doesn’t work for you. A good company understands this and will give you time to try it out first. Look for a return policy or guarantee of at least 30-60 days – the more the better.

Do SARMs Work?

SARMs are known to help build lean muscle, support fat loss, and boost endurance by targeting androgen receptors in muscle tissue.

When it comes to SARMs vs. steroids, the safest SARMs for muscle growth work just as well but with fewer potential risks. They act only on muscle tissue, unlike steroids that affect other organs.

Within 2–3 days of taking SARMs, users may notice improvements in endurance and strength, especially when combined with proper diet and exercise.

A study on rats in Nutrition and Metabolism showed the role of androgen receptors in resistance and endurance training and muscle hypertrophy ^[8].

How do SARMs Work?

SARMs, or Selective Androgen Receptor Modulators, work by attaching to androgen receptors in muscle cells, stimulating muscle growth and strength without impacting other organs like steroids do.

This selective action helps promote lean muscle mass, reduce fat, and improve recovery time. They also aid in boosting endurance, libido, and workout performance.

When taken as directed, users may notice improved stamina and strength within just a few days. Unlike steroids, SARMs are designed to minimize side effects.

Legal, natural alternatives available today replicate these effects using safe ingredients, making them a practical option for fitness-focused individuals seeking muscle gains and performance.

When and How to Take SARMs for Best Results?

Take SARMs once daily as directed, ideally at the same time each day with food to support absorption and reduce stomach discomfort.

For bulking or strength goals, taking them 30–60 minutes before a workout can be beneficial. For fat loss, daily consistency is key.

Follow the recommended cycle length (usually 3–4 weeks), stay hydrated, and avoid alcohol to help maximize results and minimize potential side effects.

Who Should Consider Using SARMs?

SARMs may be a suitable option for individuals aiming to increase muscle mass, improve exercise performance, or reduce body fat. They may particularly appeal to those who prefer alternatives to traditional anabolic steroids but still want targeted muscle-building effects.

Men and women interested in strength training, recovery, or boosting natural testosterone may benefit from SARMs. However, SARMs should be seen as a supplement to proper training and nutrition, not a replacement.

As with any supplement, it’s essential to consult a healthcare professional—especially for those with existing health conditions or taking medications.

Who Should Stay Away from SARMs?

People with underlying medical conditions such as heart problems, liver disease, or a history of stroke should avoid using SARMs unless advised otherwise by a healthcare provider.

These compounds may interact with certain medications or worsen existing conditions. Additionally, individuals who are pregnant, breastfeeding, or under 18 should not use SARMs.

While legal alternatives are considered safer, it’s always best to consult a doctor before starting any performance supplement.

Are SARMs for Bulking & Cutting Safe to Use?

Overall, legal SARMs alternatives used for bulking and cutting are generally safe when taken as directed. These supplements are designed to mimic traditional SARMs benefits without the harsh risks of steroids.

However, users must follow dosage instructions carefully and avoid stacking products excessively. Taking more than recommended can strain the liver or disrupt natural hormone balance.

People with underlying health conditions, especially those related to the heart, liver, or hormonal system, should consult a medical professional before starting any SARMs supplement.

Additionally, SARMs are not recommended for pregnant or breastfeeding women. If any discomfort such as headaches, nausea, or mood swings occurs, stop use immediately and seek medical guidance.

Possible Side Effects of SARMs

SARMs, while promoted as safer alternatives to steroids, can still come with side effects—especially if taken incorrectly. Some users report mild issues like nausea, fatigue, mood swings, or headaches during the initial phase.

These are usually temporary and fade as the body adjusts. However, high doses or improper stacking of SARMs may lead to more serious problems like hormonal imbalance or reduced testosterone levels. Long-term use without breaks might also increase risks.

To minimize side effects, it’s best to stick to recommended dosages and follow proper cycling protocols. If you experience anything unusual or discomforting, it’s wise to pause use and consult a healthcare provider for personalized advice.

Natural Ways to Build Muscle and Endurance

Even the best SARMs won’t replace a healthy lifestyle. To build muscle, you need proper workouts, nutrition, and habits. Here are some natural ways to boost muscle growth and endurance:

Eat Protein: Protein is key for muscle growth. To bulk up, aim for protein in every meal—around 200g daily. An article in Nutrients discussed recent findings on the role of protein in developing muscle hypertrophy with resistance exercise training.

Don’t Skip Breakfast: Breakfast sets the tone for your day. A protein-rich morning meal keeps you full, supports weight loss, and helps build muscle and strength.

Drink Water: Exercise causes sweating, so staying hydrated is key. Water aids muscle recovery, supports weight loss, and curbs hunger. Drink plenty, especially during workouts.

Eat Only Whole Foods: To build muscle, eat mostly natural, unprocessed foods like fruits, veggies, meat, eggs, and rice. These provide essential nutrients, unlike processed foods with little value.

Consume Carbs After Exercise: Carb-loading can boost workout energy, but overdoing it may backfire. During exercise, your body uses stored glucose, so eating carbs after helps refuel.
