RAD-140
Testolone • Selective Androgen Receptor Modulator
For Research Purposes Only • Not for human consumption • Laboratory research use only
RAD-140, also known as Testolone, is a Selective Androgen Receptor Modulator (SARM) developed by Radius Health Inc. It was initially investigated for potential applications in muscle wasting conditions and breast cancer. As a SARM, it selectively binds to androgen receptors in specific tissues.
SARMs (Selective Androgen Receptor Modulators) are a class of compounds that selectively target androgen receptors. Unlike traditional androgens, they are designed to have tissue-selective activity—meaning they may interact differently with receptors in muscle versus other tissues.
Molecular Formula: C20H16ClN5O2 • Molecular Weight: 393.83 g/mol • CAS Number: 1182367-47-0
Research indicates RAD-140 demonstrates high affinity for androgen receptors with tissue-selective activity. Studies suggest it preferentially activates receptors in muscle and bone tissue compared to other androgen-sensitive tissues.
Receptor binding studies published in peer-reviewed journals
Preclinical studies have examined RAD-140's effects on lean mass in animal models. Research demonstrates anabolic activity in muscle tissue with observations of increased lean mass in study subjects.
Animal model studies documented
Emerging research has investigated RAD-140's potential neuroprotective properties. Studies suggest possible protective effects in neuronal cell models, an area of ongoing scientific interest.
Neuroprotection research ongoing
Research has characterised RAD-140's selectivity ratio compared to testosterone. Studies indicate a higher anabolic-to-androgenic ratio, suggesting tissue-selective activity in experimental models.
Selectivity data available in literature
Research has examined RAD-140's oral bioavailability and half-life. Studies indicate good oral absorption and a pharmacokinetic profile suitable for once-daily administration in research protocols.
