What it is

Identity	Ligandrol, also called VK5211, is an experimental non-peptide SARM that activates androgen receptors. It is an unapproved drug.
Why people discuss it	Muscle, strength and a fuller physique drive interest; selectivity does not establish freedom from side effects.

Notes

LGD-4033, also called Ligandrol or VK5211, is an experimental SARM discussed for muscle, strength and a fuller physique. Some logs describe better workouts; others report little change, low energy or sexual and laboratory changes. It is an unapproved drug, and a stronger lift does not prove new muscle or safety.

Ligandrol is a non-peptide SARM. It activates androgen receptors, the body's receivers for signals such as testosterone. Discussion involves capsules, tablets and liquids; it is a different compound from testosterone or LGD-3303. Basaria et al. — LGD-4033 in healthy men (primary paper, PDF mirror) (Official context · Accessed 2026-09-30)

Selective does not mean side-effect free. The appeal is muscle and strength without injections. Community rankings call it stronger than Ostarine, but those comparisons cannot establish equal exposures, safety or a head-to-head winner.

What people notice

Workouts and appearance	Some report stronger lifts, better pumps, less soreness and fuller muscles. Water can contribute to the changed look.
Little change also occurs	One nearly eight-week user noticed little change; another longer log ended only 1 kg heavier as training changed.

Notes

Stronger lifts and fuller muscles. Reports describe better pumps, less soreness and faster lift progression. A fuller appearance can include water; the brief-log author explicitly questioned how much of his changed look was muscle.

Recomp depends on the rest of the picture. People discuss holding muscle while leaning out, yet food intake, extra training and stacks change the outcome. The longer log ended only 1 kg heavier after rowing increased; a nearly eight-week user noticed little change. LGD first cycle report (Personal report · Accessed 2026-09-30) · 8 week LGD4 failure?

Doses people talk about

Swallowed daily discussion	2.5–5 mg/day and 5–10 mg/day are separate chart bands. Logs include 5 mg/day nonresponse and a 5-to-10 mg/day course; these are reported exposures.
Under-the-tongue account	One person used 3 mg/day under the tongue for 11 days. Equivalent absorption or liver protection was not established.
Higher amounts	A log reached 12–15 mg/day; outlier reports reach 20–30 mg/day. These exceed the short repeated-dose trial exposures.

Notes

Swallowed/oral talk: 2.5–5 and 5–10 mg/day. These separate lower and larger daily bands recur in community/vendor charts. Logs include a 2.5 mg morning account, a liquid 5 mg/day nonresponse and a 5-to-10 mg/day course; they are descriptions, not an escalation plan.

Sublingual: one 3 mg/day report. The author dissolved a tablet under the tongue each morning for 11 days. This route is distinct from swallowing; equivalent absorption and liver protection were not established. My (brief) experience with LGD-4033 (3mg) (Personal report · Accessed 2026-09-30)

Higher and disputed amounts. A log reached 12–15 mg/day; outlier accounts reach 20–30 mg/day. An older forum reports 0.3–0.5 mg, but replies question units. Female guide bands of 1–5 mg/day are unvalidated chart talk, not studied female protocols.

The trial was a different exposure. Basaria studied 0.1, 0.3 or 1 mg orally over 21 days. Lean mass increased, but strength gains were not significant versus placebo. Testosterone and HDL fell; 24–36-hour half-life and accumulation were measured. Short-trial recovery does not establish recovery after larger community courses.

Half-life, onset & duration

Felt onset	Some report better lifts within ten days to two weeks; another noticed little until week five. Some notice little even after weeks.
Felt duration	One person described fading at 18 hours, amount unstated. No dependable single-dose or post-stop benefit window follows from the logs.
Half-life	24–36 hours comes from controlled human blood-level measurements, repeated in forums; it does not measure a pump or verify clearance of an unknown product.

Notes

Early changes versus week five. The brief user noticed better lifts within ten days; another commenter described a bench plateau breaking within two weeks. The longer-log author felt little strength difference until week five, then more PRs in weeks seven to nine.

Post-stop strength and weight vary. One author reported PRs during the first week after stopping. The eight-week bench commenter retained much of the gained weight but gave no follow-up interval.

Cycles people discuss

Blocks discussed	Six-to-eight-week blocks recur; four-week runs and eight-to-twelve-week extensions also appear. Some users stop much earlier.
Post-cycle treatment and time off	Tamoxifen or clomiphene after a run, and bloodwork, are discussed. Time-off-equals-time-on is a forum rule of thumb, not a validated recovery schedule.

Notes

Six to eight weeks; longer runs also occur. Community charts include four-week exploratory runs, six-to-eight-week blocks and eight-to-twelve-week extensions. Reports include an 11-day stop, an interrupted ten-calendar-week course and an eight-week bench log whose gains slowed at the end.

(Community discussion · Accessed 2026-09-30)

PCT and time off are contested. Forums discuss post-cycle SERMs such as tamoxifen or clomiphene, sometimes on-cycle use, and bloodwork before/during/after. The 'time off at least equals time on' heuristic and multi-week recovery stories are not validated LGD recovery schedules. LGD first cycle report (Personal report · Accessed 2026-09-30)

Stacks

MK-677 and other agents	MK-677 appears for appetite and recovery; RAD-140, Ostarine, S-4, YK-11 and cardarine occur in other combinations. Results cannot be assigned to LGD alone.
Support supplements	Fish oil and liver-support products appear, but adding them does not establish protection from harm.

Notes

Stack gains cannot be assigned to LGD alone. MK-677 appears for appetite/recovery; RAD-140, Ostarine, S-4, YK-11 and GW-501516 occur in other stack talk. The longer author added MK-677 alongside injury care. Adding agents obscures benefit and adverse-effect attribution. LGD first cycle report (Personal report · Accessed 2026-09-30)

Support supplements are not a shield. Fish oil and liver-support products appear in stack discussions alongside warnings about heavy alcohol and other liver-stressing orals. Adding 'support' does not establish protection; the brief adverse log included multiple such products. My (brief) experience with LGD-4033 (3mg) (Personal report · Accessed 2026-09-30)

Watch for

Hormones, liver and lipids	Reports include falling testosterone, low libido, fatigue and elevated liver enzymes. The short trial also found testosterone and HDL reductions.
Other unwanted effects	Nausea, abdominal discomfort, night sweats, headaches, flat mood, acne and shedding appear; female masculinization risk remains uncertain.
Serious class risks	FDA identifies liver injury, sexual dysfunction, infertility and cardiovascular risks with SARMs. Feeling stronger does not establish safety.
Sport and product identity	Ligandrol is prohibited in sport at all times in the saved WADA record. Neither a pump nor nonresponse authenticates a bottle.

Notes

Better workouts can coexist with feeling worse. The brief user stopped with nausea, abdominal discomfort, night sweats, dehydration, flat mood and reduced aerobic capacity. His liver enzymes rose and testosterone fell; other medicines make causality uncertain. Higher-dose logs include fatigue, headaches and low libido.

Feeling fine does not prove no suppression. The nonresponder had no bloodwork. The longer author described libido rising around weeks three to four then falling, despite feeling leaner and stronger.

Supporting human research

The trial was a different exposure. Basaria studied 0.1, 0.3 or 1 mg orally over 21 days. Lean mass increased, but strength gains were not significant versus placebo. Testosterone and HDL fell; 24–36-hour half-life and accumulation were measured. Short-trial recovery does not establish recovery after larger community courses. Official context

What the logs add

A stronger bench is not a measured muscle gain. One 5 mg/day commenter reported bench rising from 335 to 360 lb and about six pounds gained over eight weeks with a slight surplus. Water contribution was uncertain, and progress slowed rather than improving indefinitely. Reddit r/sarmssourcetalk
Feeling fine does not prove no suppression. The nonresponder had no bloodwork. The longer author described libido rising around weeks three to four then falling, despite feeling leaner and stronger. That author reported substantial hormone suppression; a separate user described sluggish mood. Reddit r/sarmssourcetalk Personal report
The 'dry' reputation has exceptions. Water in arms and midsection appears in a late-gain log. Reports calling LGD cleaner than 'wet' orals describe a look, not a body-composition measurement or safety advantage. Reddit r/sarmssourcetalk Community
Stack gains cannot be assigned to LGD alone. MK-677 appears for appetite/recovery; RAD-140, Ostarine, S-4, YK-11 and GW-501516 occur in other stack talk. The longer author added MK-677 alongside injury care. Adding agents obscures benefit and adverse-effect attribution. Personal report Community
