Quick Scoop
RAD-140, also called Testolone, is an investigational
selective androgen receptor modulator (SARM) that was developed to target
androgen receptors and is being studied for uses like muscle wasting and
breast cancer. In practice, people often use it for muscle-building and
strength-focused effects, but it is not an approved routine treatment and its
safety profile remains a concern.
What it may do
- May increase muscle growth and strength by activating androgen receptors.
- May support protein synthesis and lean-mass gains, which is why it is popular in bodybuilding discussions.
- Is being researched as a targeted agent in cancer-related settings, including hormone-receptor-positive breast cancer.
Main risks
RAD-140 is associated with hormone suppression, meaning it
can reduce your body’s own testosterone production. Reports also raise
concerns about liver stress, cholesterol disruption, cardiovascular strain,
mood changes, and other unknown long-term effects.
Bottom line
If you are asking “what does RAD-140 do,” the short
answer is: it is designed to act like an androgen signal in a more tissue-
targeted way, which can promote muscle-related effects, but it also carries
real health risks and is still investigational. If you want, I can also
explain how RAD-140 compares with steroids, how it differs from other SARMs,
or what the evidence says about side effects.
