RAD-140, also known as Testolone, is a selective androgen receptor modulator (SARM). Like other SARMs, RAD-140 was developed to potentially offer similar muscle-building effects to traditional anabolic steroids but with a reduced impact on other tissues, aiming to minimize unwanted side effects.

Research on RAD-140 has primarily focused on its potential in increasing muscle mass and strength. It selectively targets androgen receptors in muscle and bone tissues, aiming to promote anabolic effects without causing many of the androgenic side effects typically associated with anabolic steroids.

Early preclinical studies in animals showed promising results, indicating increased muscle growth and improved physical performance without some of the adverse effects on prostate and other androgen-sensitive tissues.

However, it’s important to note that while the initial research on RAD-140 appears promising, the studies are limited, and comprehensive human trials are lacking. As a result, the long-term safety, potential side effects, and overall efficacy of RAD-140 in humans are not fully understood.

The regulatory status of RAD-140 and other SARMs is also a matter of concern, as they are often marketed and sold as research chemicals or dietary supplements without regulatory approval for human consumption.

Given the limited research and potential risks associated with SARMs, including RAD-140, it’s crucial to approach their use with caution. Consulting a healthcare professional before considering the use of RAD-140 or any similar compound is highly recommended to understand potential risks, legal implications, and lack of comprehensive safety data.
