Best SARMs For Bulking & Cutting In 2025: A Comprehensive Guide

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?

These are some of the Crazy Bulk Best SARMs for sale on the market:

Ostarine (MK 2866)

Developed in the 1990s, this non-steroidal SARM was originally a treatment for osteoporosis and muscle weakness. Research consistently shows that it can lead to an increase in lean body mass without a change in body weight.

Some of the Ostarine side effects may include back pain, nausea, fatigue, and headache ^[1]. There are no really serious Ostarine MK 2866 symptoms that should occur.

Ligandrol (LGD 4033)

This is a highly bioavailable safest SARM that many say is excellent for building muscle, enhancing athletic performance, improving recovery, and developing size. The ideal LGD 4033 dosage is 5-10 mg daily for 6 to 10 weeks ^[1].

As of yet, there’s only been limited research on this SARM but existing studies show it increases lean muscle mass but does not cause weight loss ^[1]. The LGD 4033 review posts online mostly indicate that men were very happy with their results.

Ibutamoren (MK 677)

This is a SARM which is specifically an agonist of the receptor ghrelin, which regulates hunger. The MK 677 benefits include suppressing hunger for potential weight loss and producing human growth hormone (HGH). This promotes muscle growth and cell regeneration.

Low HGH may cause low libido and impotence issues which may resolve with MK677. Erectile dysfunction can improve with a regimen of this SARM. Although there is evidence of MK 677 brain damage in rats, this result has never shown up in human trials ^[2].

A study in the Annals of Internal Medicine found that the MK 677 side effects included an increase in appetite, muscle pain, and mild lower extremity edema ^[3].

Cardarine (GW 501516)

Two pharmaceutical companies developed this compound in the 1990s. Rather than being a SARM, it’s actually a peroxisome proliferator-activated receptor (PPAR) agonist. It activates receptors that primarily exist in the muscles.

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)

A professor by the name of Thomas Burris of the Scripps Research Institute developed this purely as a tool for use in studies. However, it has benefits as a bodybuilding product, and it’s also an amazing fat burner which can lead to rapid weight loss.

In addition, it can balance blood sugar metabolism. Evidence confirms the safety of SR9009 for females and males.

Testolone RAD 140

This is a SARM that can raise testosterone levels by mimicking its behavior and thus helps build muscle mass and strength. A pharmaceutical company developed it in 2020 for medical use in androgen replacement therapy. Many people claim the RAD 140 transformation after a few weeks of use is quite dramatic.

In addition, it can boost sexual arousal and improve stamina. Testolone also provides additional performance energy. There aren’t a lot of RAD 140 side effects, but there is a chance that it could lead to liver damage ^[4].

It’s available in capsule and liquid form, and if you want to know how to take RAD 140 liquid the directions are simple. Just put the liquid under your tongue using an eyedropper, wait for 10-15 seconds, and then swallow.

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.

What is the Science of 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 ^[5].

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.

What are Some of the Ingredients Included 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

This is an essential nutrient which the body does not make naturally, so we acquire it from foods such as red meat, liver, and egg yolks. Choline is essential for the brain and nervous system, regulating muscle control, mood, memory, and learning.

In addition, it makes the protective membrane surrounding the cells. It can improve the bioavailability of calcium so it can enhance muscle contraction. An article in Nutrients discussed the crucial role choline plays as an essential nutrient for skeletal muscle ^[7].

Alpha Lipoic Acid

This is a powerful compound which exists naturally in the body and is also in some foods. It’s essential in energy production, as it assists the body in converting sugars into fuel. In addition, it’s a potent antioxidant which can heal the body and strengthen immunity.

It’s good for diabetes, as it can balance blood sugar and increase insulin sensitivity. When it comes to muscles, ALA can both repair muscle damage and enhance strength. It helps move more oxygen through your lungs, also helping to extend workout time.

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 ^[8].

Beetroot

This is an earthy vegetable which falls into the category of a superfood. It supports heart health and can help decrease blood pressure. Beetroots contain alpha-lipoic acid, which can lower blood sugar and help treat diabetes.

There’s some evidence that beetroot can help raise the amount of oxygen that is transported to the muscles, which helps build them. It may also help improve exercise endurance, but the research varies.

A study in Nitric Oxide showed that high doses of beetroot improved the performance of professional cyclists ^[9].

Vitamin C

This vitamin exists largely in berries and cruciferous vegetables and is a powerful antioxidant essential for the growth and development of cells. It is key in the formation of muscles, cartilage, and blood vessels. There’s some evidence that it could help people retain muscle mass to an older age in life.

Vitamin C can help repair damage to the muscles, and it strengthens the immune system. A study in the International Journal of Sports Nutrition Exercise Metabolism found that Vitamin C supplementation reduced muscle soreness and oxidative stress ^[10].

Caffeine Anhydrous

This is dehydrated caffeine, making it much more potent than the regular stimulant. It can speed up the metabolism, putting the body into the fat-burning state of thermogenesis.

This in itself can lead to weight loss, but it also gives you a lot of energy so you burn more calories. Caffeine can improve exercise endurance, and it can also enhance alertness and mental focus. SARMs for fat loss often include this ingredient.

A literature review in the Journal of the International Society of Sports Nutrition concludes that caffeine may improve muscle strength and power ^[6].

Do SARMs Work?

When it comes to SARMs vs. steroids, the safest SARMs for muscle growth work as well as steroids with fewer potential risks. They indeed work well, and they only act on muscle tissue without impacting other bodily tissue like steroids. Within 2-3 days of taking SARMs, your athletic endurance and muscle strength should improve.

A study on rats in Nutrition and Metabolism showed the role of androgen receptors in resistance and endurance training and muscle hypertrophy ^[11].

What Are Some Natural Ways to Build Muscle and Endurance?

Even the best SARMs for strength won’t make up for an unhealthy lifestyle. If you want to build up your muscles, you have to work them out, take in the right nutrients, and follow healthy habits. I have compiled some of the best ways to naturally build up your muscles and improve exercise endurance, for your information:

Eat Protein: Protein is the primary building block in the development of the muscles. If you want to bulk up, it’s a good idea to consume some protein at every meal. The average person requires about 200g of protein each day in order to develop significant muscle mass. An article in Nutrients discussed recent findings on the role of protein in developing muscle hypertrophy with resistance exercise training ^[13].

Don’t Skip Breakfast: Breakfast is the key meal of your day because it sets the tone for the rest of your nutrition. Protein in the morning keeps you full so you’re less likely to overeat later in the day, which can help with weight loss. It’s also crucial in building muscle mass and strength.

Drink Water: Exercise makes you sweat, which can lead to dehydration if you don’t take in enough water. It can also interfere with the recovery of your muscles, which prevents development. Water fills up your stomach so you consume fewer calories, which is good for weight loss. Drink water throughout the day, and in particular during your workout.

Eat Only Whole Foods: In order to develop muscle mass, the foods that you take in must be primarily natural and unprocessed, like fruits and vegetables, fish, meat, eggs, and rice. They contain the protein and nutrients you require to develop the muscles, while processed food contains little if any nutritional value.

Consume Carbs After Exercise: Many people like to carb-load before working out to give them energy, but the risk is that you will overdo it and consume too much. While you are exercising, your body uses your glucose stores as fuel for the workout. Afterward, taking in some carbs can replenish those stores.

Final Verdict

Taking types of SARMs like Ostarine (MK 2866), Ligandrol (LGD), SR 9009, or Ibutamoren can be a great way to increase your exercise endurance and build up great muscle mass and strength. It may also give your libido a big kick.

Because there are some risks, your best bet is to take a safe, legal alternative which will provide you with the same benefits. In this article, I have highlighted 6 products from the Crazy Bulk line, as in my opinion, they are the best SARMSs company that sells legal, natural safe supplements on the market.

Any of these products should definitely push you forward to meet your goals in the gym and in front of the mirror. They have the best SARMs for bulking and cutting, the best SARMs stack collection, as well as SARMs for weight loss.

In my research, I have found that they generally greatly enhance performance, muscle bulk, and strength and most users are very happy with the results.
