What Does RAD 140 Do? Uncovering Its Benefits

If you are a fitness enthusiast or a bodybuilder, you must be aware of the importance of anabolic steroids. These compounds are known for their muscle-building and fat loss effects. RAD 140, also known as Testolone, is a selective androgen receptor modulator (SARM) that has gained popularity in recent years. Its unique mechanism of action has made it a favorite among bodybuilders and athletes. In this article, we will explore what RAD 140 does and its benefits.

What Is RAD 140?

RAD 140 is a non-steroidal SARM that was developed to replace testosterone replacement therapy (TRT). It is one of the most potent SARMs on the market, with an anabolic to androgenic ratio of 90:1. This means that it is 90 times more anabolic than testosterone and has a significantly lower androgenic activity.

How Does RAD 140 Work?

RAD 140 works by selectively binding to androgen receptors in the body. Androgen receptors are found in various tissues, including muscles, bones, and fat cells. When RAD 140 binds to these receptors, it triggers an increase in protein synthesis, which leads to muscle growth. Besides, RAD 140 also stimulates the production of red blood cells, which enhances endurance and muscle recovery.

Benefits of RAD 140

1. Increased Muscle Mass and Strength

RAD 140 is known for its ability to increase muscle mass and strength. Several studies have shown that RAD 140 can lead to a significant increase in lean body mass, even with a low dosage. One study found that a daily dosage of 10mg of RAD 140 for eight weeks resulted in an average increase of 3.3lbs of muscle mass.

2. Fat Loss

RAD 140 can also aid in fat loss. Since it increases muscle mass and metabolic rate, it leads to a higher calorie burn throughout the day, resulting in weight loss. One study found that RAD 140 reduced fat mass in the body while preserving muscle mass.

3. Enhanced Endurance

RAD 140 stimulates the production of red blood cells, which enhances endurance. It increases the oxygen-carrying capacity of the blood, which leads to faster recovery and better performance during workouts.

4. Improved Bone Health

RAD 140 improves bone health by increasing bone density. It can prevent osteoporosis and other bone-related diseases, making it an excellent choice for older adults.

5. Improved Brain Function

RAD 140 has neuroprotective properties that can improve brain function. It can enhance memory, learning, and cognition.

Is RAD 140 Safe?

RAD 140 is relatively safe when taken in low doses. However, like all SARMs, RAD 140 can have side effects. Some of the common side effects are nausea, headaches, and fatigue. Besides, RAD 140 can also suppress the production of natural testosterone in the body. It is essential to consult a healthcare professional before taking RAD 140.

How to Take RAD 140?

The optimal dosage of RAD 140 is 10-30mg per day. It is recommended to start with a low dosage and gradually increase it to avoid side effects. RAD 140 has a half-life of 16-20 hours, and it is best to split the dosage into two servings throughout the day. RAD 140 should be taken for eight weeks followed by a four-week break before starting again.


RAD 140 is a potent SARM that has several benefits concerning muscle growth, fat loss, endurance, and bone health. However, it is vital to take it in recommended doses and under medical supervision. Consult a healthcare professional before starting any new supplement, including RAD 140.
