⚡What it does
- SARM — selective androgen receptor modulator; muscle and bone anabolism at lower androgenic cost than steroids
- Studied (legitimately) for muscle wasting — that's the extent of the human data
⚠Key risks
- The #1-selling SARM worldwide — sold as 'not for human use' with zero finished-product quality control
- Suppresses natural testosterone — PCT debates rage because nobody has real data
- Lipid suppression (HDL crash) and liver enzyme elevations documented in case series
- WADA-banned: athletes have lost medals over ostarine supplements
✚Overdose signs
- Not an acute-overdose drug — chronic: jaundice, severe acne, mood changes
- Chest symptoms from lipid/cardiovascular strain
- Testosterone-crash symptoms on cessation
