RAD-140 (Testolone)
A strong oral SARM (testolone) marketed for pronounced strength and lean mass gains. It was originally explored for muscle wasting and breast cancer.
- Half-life
- 20 h
- Out of system
- ~4 days
- Route
- Oral
- Level
- Intermediate
Daily dosing holds steady levels. After the last dose, roughly 97% has cleared in ~4 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What RAD-140 (Testolone) is used for
- Among the more potent SARMs for adding strength and lean muscle
- Preclinical work suggested anabolic effects with relative prostate sparing
How it's typically used
Reported research and user ranges are around 10 mg daily for 8-12 weeks.
What to watch for
- Case reports link RAD-140 to drug-induced liver injury (hepatotoxicity)
- Marked testosterone suppression means a PCT is generally required after use
- Not approved for human use; an unapproved research chemical banned in sport
About SARMs
- What they are
- Selective androgen receptor modulators — oral compounds designed to hit muscle and bone androgen receptors while sparing prostate and skin. None is an approved medicine anywhere.
- How they're run
- Taken orally once a day, typically in 8–12 week blocks.
- What to watch
- The "non-suppressive" reputation is marketing: most suppress natural testosterone, and several are liver-toxic. Independent testing repeatedly finds products containing something other than the label. Bloodwork before and after is the minimum.
