RAD-140, also known as Testolone, is a selective androgen receptor modulator (SARM) that has gained popularity in the fitness and bodybuilding communities. Here is an in-depth review of RAD-140, including its uses, functions, benefits, and dosages.

Uses: RAD-140 was initially developed to treat conditions such as muscle wasting and osteoporosis. However, it is now commonly used by athletes and bodybuilders as a performance-enhancing compound and for muscle-building purposes.

Functions: As a SARM, RAD-140 selectively binds to androgen receptors in muscle and bone tissues, promoting anabolic effects without causing significant androgenic side effects. It stimulates the androgen receptors in the same way as testosterone, leading to increased protein synthesis, enhanced muscle growth, and improved strength and endurance.


  1. Muscle growth: RAD-140 is highly effective at promoting lean muscle mass gains. Users often report significant increases in muscle size and strength.
  2. Fat loss: RAD-140 can aid in reducing body fat by boosting metabolism and promoting the breakdown of fat cells.
  3. Enhanced endurance: Users may experience improved stamina and endurance, allowing for longer and more intense workouts.
  4. Faster recovery: RAD-140 can accelerate the recovery process, reducing muscle soreness and allowing for quicker return to training.
  5. Increased bone density: RAD-140 has shown potential in improving bone health and increasing bone mineral density.
Benefits of TESTOLONE for athletes and bodybuilders
RAD-140 (Testolone) offers several benefits for athletes and bodybuilders:
  1. Increased Muscle Mass: RAD-140 is highly effective at promoting lean muscle mass gains. It stimulates protein synthesis, leading to significant increases in muscle size, strength, and density. This benefit is particularly valuable for athletes and bodybuilders aiming to build a well-developed and muscular physique.

  2. Enhanced Strength and Power: RAD-140 can improve strength and power output, allowing athletes and bodybuilders to perform at higher levels. It enhances muscle force generation, enabling individuals to lift heavier weights and perform explosive movements, such as sprinting or jumping.

  3. Improved Endurance and Stamina: RAD-140 can enhance endurance by increasing red blood cell count and oxygen-carrying capacity. This benefit enables athletes to sustain high-intensity efforts for longer periods, improving performance in sports that require endurance, such as cycling, running, or swimming.

  4. Faster Recovery: RAD-140 accelerates the recovery process by reducing muscle damage and inflammation. It helps athletes and bodybuilders recover from intense training sessions or competitions more quickly, allowing them to resume training sooner and maintain a consistent workout schedule.

  5. Fat Loss and Body Composition: RAD-140 can aid in reducing body fat while preserving lean muscle mass. It boosts metabolism and promotes the breakdown of fat cells, assisting athletes and bodybuilders in achieving a leaner and more defined physique.

  6. Improved Bone Strength: RAD-140 has shown potential in increasing bone mineral density and enhancing bone health. This benefit is crucial for athletes, as it can help reduce the risk of injuries, especially in high-impact sports.

Dosages: RAD-140 is a potent compound, and it is crucial to use it responsibly. The recommended dosage ranges from 10 to 30mg per day. Beginners should start with a lower dose and gradually increase it to assess tolerance and minimize the risk of side effects. The cycle length typically lasts 8 to 12 weeks, followed by a post-cycle therapy (PCT) to help restore natural hormone production. 

Before considering RAD-140 or any other performance-enhancing substance, it is advisable to consult with a healthcare professional for personalized advice and guidance.


The anabolic/androgenic ratio is a measurement that compares the anabolic (muscle-building) effects to the androgenic (masculinizing) effects of a compound. The higher the anabolic ratio relative to the androgenic ratio, the more favorable the compound is considered for muscle-building purposes.

  1. RAD-140 (Testolone): RAD-140 is known for its high anabolic potency and favorable anabolic/androgenic ratio. While specific ratio data may not be available, anecdotal reports suggest that RAD-140 exhibits strong anabolic effects with minimal androgenic side effects. This selectivity makes it a desirable compound for muscle growth and performance enhancement.

  2. Testosterone: Testosterone has an anabolic/androgenic ratio of 1:1, as it provides a balance between anabolic effects and androgenic side effects. While testosterone is an effective anabolic agent, it also has significant androgenic properties, which can lead to side effects such as increased facial and body hair, acne, and prostate enlargement. The use of supraphysiological doses of testosterone can further increase the risk of androgenic side effects.

In terms of anabolic/androgenic ratio, RAD-140 is considered more favorable than testosterone. RAD-140's selective binding to androgen receptors in muscle and bone tissues results in anabolic effects without significant androgenic side effects. On the other hand, testosterone provides a full range of androgenic effects throughout the body, which may increase the likelihood of experiencing androgenic side effects.

It's important to note that while anabolic/androgenic ratios can provide some insight into the potential effects of compounds, they are not the sole determinants of a compound's overall efficacy or side effect profile. Other factors, such as dosage, individual response, and overall health, should also be taken into consideration when comparing the effects of RAD-140 and testosterone. Consulting with a healthcare professional is recommended for personalized advice and guidance.
