| Evidence boundary | RAD140, vosilasarm and the online term Testolone refer to an investigational SARM candidate; Testolone is not testosterone. A first-in-human study enrolled 22 postmenopausal women with advanced breast cancer and reported target engagement, preliminary antitumour activity and frequent liver-test abnormalities. This does not establish bodybuilding or performance benefit, safety in healthy users or approval. FDA identifies marketed RAD-140 products as unapproved drugs, and WADA prohibits RAD140 at all times. | Ostarine, enobosarm, GTx-024 and MK-2866 refer to the same investigational SARM candidate in the reviewed literature. Controlled trials reported lean-body-mass signals in selected older adults and cancer populations, but do not establish bodybuilding benefit, long-term safety or product approval. FDA states that no SARM is approved and warns of serious harms. Online naming does not establish identity or amount, and WADA 2026 prohibits enobosarm at all times. | Ligandrol and LGD-4033 identify an investigational nonsteroidal SARM candidate. A 21-day placebo-controlled study in 76 healthy men found an exposure-related lean-mass signal alongside suppression of total testosterone, SHBG and HDL. The study was too small and short to establish clinical or bodybuilding benefit or long-term safety. FDA identifies marketed LGD-4033 products as unapproved drugs, and WADA 2026 prohibits ligandrol at all times. |

Missing fields mean information is unavailable in the current structured dataset, not that a molecule has no risks or uncertainties. English translations retain the original evidence boundaries. Where translation is not yet verified, the original Thai excerpts remain available under an explicit label. Sources retain their original language.
