Testolone RAD-140

One of the more popular bodybuilding-community experimental muscle-building compounds, with some early-stage human trials exploring its use in specific hormone-related cancer treatments. Solid human data remain limited to those early trials, and most claims about its muscle-building effects in healthy people come from personal reports rather than controlled research.

Also known as RAD140, Vosilasarm, 4O87Q44KNC, RefChem:178518, SARM RAD140, EP 0062, Testolone (RAD140), Vosilasarm; RAD-140
