Category-level conceptual illustration, not a map of this molecule's receptor targets. It is not a treatment outcome and does not establish efficacy or safety.

QUICK ANSWER · AEO / GEO

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.

What remains unknown?

Insufficient data in the current dataset

What limits these conclusions?

  • Oncology target engagement ≠ bodybuilding benefit; Testolone ≠ testosterone; Phase 1 ≠ approval or long-term safety

This overview does not replace the detailed adverse-event and product-specific risk discussion in the complete Thai profile or the original sources.

EVIDENCE BOUNDARY

What this overview does not establish

  • An evidence grade does not rank this molecule against another treatment.
  • A molecule name does not establish the identity, purity or regulatory status of a product.
  • Animal, cell or biomarker findings do not automatically establish human clinical benefit.
  • Approval in one country or indication does not transfer globally.

Where can I check the evidence?

Original sources from the same evidence record used by Compare. Read each source's population, methods, limitations and date; a citation is not product endorsement.
