Ligandrol (LGD-4033)
A potent oral SARM (LGD-4033) valued for size and strength gains at low milligram doses. It reached early human trials for muscle wasting.
- Half-life
- 1.3 d
- Out of system
- ~6 days
- Route
- Oral
- Level
- Intermediate
Daily dosing holds steady levels. After the last dose, roughly 97% has cleared in ~6 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Ligandrol (LGD-4033) is used for
- Noticeable lean mass and strength gains at just 5-10 mg per day
- Human phase 1 data showed dose-dependent lean mass increases over a few weeks
How it's typically used
Trial and user ranges run about 5-10 mg daily for 8-12 weeks.
What to watch for
- Strongly suppresses natural testosterone even at low doses, so plan for a PCT
- Can transiently raise liver enzymes and lower HDL; bloodwork is advised
- 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.
