Disclaimer: People ought to solely use SARMs for analysis functions, as they don’t seem to be FDA-approved and should have adversarial results. Dr. Touliatos is out there for session ought to readers have any questions or considerations.
LGD 4033, or Ligandrol, is a potent selective androgen receptor modulator (SARM) usually utilized by weightlifters for bulking functions because of its optimistic results on muscle power and hypertrophy (1).
Ligandrol and different SARMs present promise for the potential therapy of cachexia because of their anabolic results and tissue selectivity. LGD 4033 strongly binds to the androgen receptor, much like steroids. Nonetheless, it’s a weak agonist within the prostate.
Due to this fact, the androgenic results of testosterone and different anabolic steroids won’t happen with LGD 4033, stopping prostate hyperplasia.
LGD 4033 was created in 2007 and synthesized by Ligand Prescribed drugs, therefore its identify, Ligandrol, an American biotechnology firm.
As a consequence of its current formulation, the long-term results of LGD 4033 are at present unknown, with it being labeled as a analysis compound and but to obtain FDA approval.
Thus, LGD 4033 just isn’t authorized for beauty functions. Nonetheless, it’s authorized for analysis functions; subsequently, researchers might administer LGD-4033 to rodents.
Though LGD 4033’s unwanted side effects will not be but totally recognized, the World Anti-Doping Company (WADA) has concluded that its optimistic results on athletic efficiency are at present apparent, therefore its ban on Ligandrol and different SARMs in skilled sports activities since 2020 (2).
Ligandrol Advantages
Muscle Mass
Dr. Michael Moeller says, “LGD 4033 stimulates testosterone and androgen receptors with out changing into DHT or estrogen.” Nonetheless, Dr. Moeller notes that scientific trials haven’t but confirmed LGD 4033 to be a worthy alternative for testosterone alternative remedy in drugs. Dr. Moeller states that ladies and men looking for anabolic results, particularly of the youthful era, are efficiently using LGD 4033 in the present day when it comes to muscle constructing.
In part 1 scientific trials, LGD 4033 has produced notable will increase in lean muscle mass. One group of wholesome younger males acquired 1 mg/day for 3 weeks and gained 1.21 kg (3). Contemplating the transient cycle, modest dosage, and lack of coaching stimulus to maximise muscle hypertrophy, these are very promising outcomes.
Muscular Power
Within the above-cited research, the boys additionally recorded elevated leg press power and energy on the stairclimber earlier than and after the 3-week cycle. That is regardless of not commonly performing these particular workouts all through the trial.
Our sufferers usually report distinctive power outcomes on LGD 4033, even with diminished energy.
We discover that including 30 kilos or extra to squat and bench press workouts is comparatively frequent after a cycle of LGD 4033, with its results on power being superior to its means so as to add lean muscle.
LGD 4033 doesn’t produce any notable fats loss, not like Ostarine or Cardarine, making it extra optimum for bulking than slicing.

Ligandrol Facet Results
Based on Affiliate Professor Nial Wheate, “2013 and 2018 human trials demonstrated the security of LGD 4033.” He additionally provides that LGD 4033 has “fewer unwanted side effects” compared to anabolic steroids. Regardless of preliminary success in scientific analysis, Wheate warns that LGD 4033 is “nonetheless experimental.”
Two gentle unwanted side effects we see with LGD 4033 are complications and a dry mouth. Nonetheless, extra troublesome unwanted side effects also can happen, comparable to:
- Ldl cholesterol alterations
- Testosterone suppression
- Liver toxicity
- Water retention and gynecomastia
- Male sample baldness
Ldl cholesterol
LGD 4033 has a considerably destructive impact on high-density lipoprotein (HDL ldl cholesterol), with scientists observing an approximate discount of 40% in 3 weeks on a dosage of 1 mg/day (4).
Beneficiant ranges of HDL ldl cholesterol cut back the danger of arteriosclerosis, bettering coronary heart well being. Thus, such sizeable reductions enhance the danger of myocardial infarction, much like the extent of oral anabolic steroids.
Such elevations in blood strain could also be attributed to LGD 4033 being administered orally and thus being metabolized by the liver. This will stimulate the enzyme hepatic lipase, inflicting deleterious alterations in HDL ldl cholesterol. The identical analysis recorded low-density lipoprotein (LDL) ranges remaining secure. Nonetheless, serum triglycerides decreased by virtually 15%, probably lowering some cardiovascular pressure.
Testosterone Suppression
SARMs, regardless of being non-steroidal, can nonetheless suppress pure testosterone ranges because of their aggressive binding to the androgen receptor. This consequently decreases luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
We’ve discovered LGD 4033 to be probably the most potent SARM available on the market and probably the most suppressive. Within the beforehand cited trial that administered 1 mg/day of Ligandrol, contributors’ whole testosterone declined by 50%. Free testosterone additionally skilled the same 40% discount.
After 56 days of drug cessation, customers’ endogenous testosterone returned to plain ranges. Thus, contemplating customers generally take 5 mg/day of LGD 4033 and upwards, testosterone suppression on this case is prone to be extra extreme, indicating important non permanent injury to the hypothalamic-pituitary-testicular axis (HPTA).
Dr. Thomas O’Connor says, “LGD 4033 customers are going to be briefly shut down,” primarily based on his expertise of treating a whole lot of males who’ve utilized the SARM. Dr. O’Connor provides that testosterone suppression is “the principle threat of LGD 4033” and that his sufferers have skilled melancholy till their hormones normalize.
Liver Toxicity
In a randomized scientific trial, LGD 4033 was given to 76 wholesome males, producing no notable adjustments in serum aminotransferases in dosages of 0.1, 0.3, and 1 mg/day over 21 days (5).
Nonetheless, one analysis paper reported a person creating jaundice following 10 mg/day of LGD 4033 for two weeks. Thus, the hepatotoxicity degree of LGD 4033 is prone to be dose-dependent, which helps what we now have discovered anecdotally.
Additional analysis reported a 24-year-old man with hepatocellular liver harm following 9 weeks of LGD 4033 use (6). The dosage being utilized was not said, so warning needs to be exercised when using this SARM, with additional analysis required to ascertain dosages inducing hepatotoxic results.
Water Retention and Gynecomastia
In concept, LGD 4033 shouldn’t produce estrogenic unwanted side effects, because it doesn’t aromatize or instantly stimulate estrogen receptors.
Nonetheless, we see Ligandrol compete with pure testosterone when binding to the androgen receptor. LGD 4033’s increased affinity signifies that the physique’s pure testosterone concedes this twin and as an alternative is more and more out there for binding to different receptors, comparable to estrogen.
Thus, LGD 4033 can not directly trigger increased estrogen ranges, rising the danger of potential bloating or gynecomastia.
Male Sample Baldness
Some LGD 4033 customers report shedding or recession of hair on the scalp, much like anabolic steroids. There are two explanation why such hair loss is feasible, regardless of LGD 4033’s weak androgenicity. Much like how estrogen ranges can not directly rise from extra pure testosterone binding to different receptors, that is additionally how LGD 4033 can enhance DHT ranges, elevating the physique’s pure degree of 5-alpha reductase.
Dihydrotestosterone (DHT) is the hormone answerable for follicle miniaturization on the scalp, with extra ranges inflicting androgenetic alopecia.
One other doable reason for LGD-4033-induced hair loss is telogen effluvium. As much as 90% of hair follicles are actively rising on the scalp, and 10% are resting. When hair follicles are within the rising or anagen part, common pure hair loss is 100 hairs a day. Nonetheless, within the occasion of telogen effluvium and sudden hormonal adjustments to the physique, 30% of hair follicles might enter the resting or telogen part. This situation leads to the day by day lack of 300 hairs.
We discover that introducing SARMs to the physique can stimulate telogen effluvium, basically tripling the extent of hair loss. Nonetheless, such shedding is usually reversible post-cycle. Our sufferers usually report hair thickening after 1–2 weeks following cycle cessation, with hormones regulating and hair follicles returning to the anagen or rising part.
LGD 4033 Dosage
A dosage has not been established by medical consultants right now, with LGD 4033 but to be FDA-approved. Nonetheless, in trials, 0.1, 0.3, and 1 mg dosages have been generally used, with increased dosages yielding extra pronounced outcomes.
Male weightlifters taking LGD 4033 for physique-enhancing functions will usually take 2–10 mg/day.
Females will go for the decrease dosages on this vary, comparable to 2 mg/day, to stop virilization unwanted side effects occurring.
LGD 4033 is run as soon as per day. Dosages could also be tapered, making certain continued outcomes throughout the cycle. Thus, 1-2 mg/day could also be a beginning dosage, with will increase of 1-2 mg every week till a desired most dosage is achieved. Equally, some customers might not decide to taper cycles out of comfort.
Though males can take as much as 10 mg/day of LGD 4033, dosages in extra of 6 mg/day produce minimal extra leads to our expertise.
LGD 4033 Cycle
For Males: Non-Tapered Cycle
- LGD 4033: 6 mg/day for 8 weeks.
For Males: Tapered Cycle
- Week 1: 4 mg/day
- Week 2: 4 mg/day
- Week 3: 5 mg/day
- Week 4: 5 mg/day
- Week 5: 6 mg/day
- Week 6: 6 mg/day
- Week 7: 6 mg/day
- Week 8: 6 mg/day
For Girls
- Week 1: 1 mg/day
- Week 2: 1 mg/day
- Week 3: 2 mg/day
- Week 4: 2 mg/day
Larger dosages and prolonged cycle durations will exacerbate unwanted side effects in customers.
LGD 4033 Outcomes: Earlier than and After Photos

This Reddit person carried out an 8-week LGD 4033 cycle, administering 5 mg/day. He initially gained 13 kilos, which decreased to 10 kilos when water weight subsided post-cycle. His food regimen consisted of a beneficiant calorie surplus; thus, a few of this weight may be attributed to elevated subcutaneous physique fats.

He talked about that family and friends commented on his bigger arm dimension 3 weeks into the cycle, a few of whom have been unaware of his SARM use. Contemplating his excessive calorie consumption, his outcomes when it comes to muscle hypertrophy from LGD 4033 may very well be thought of gentle. Nonetheless, there was a dramatic distinction in muscular power, with before-and-after logs detailed as follows:
Bench Press
- Earlier than: 185 lb x 5 repetitions
- After: 205 lb x 8 repetitions
Overhead Press
- Earlier than: 110 lb x 5 repetitions
- After: 125 lb x 6 repetitions
Squat
- Earlier than: 230 lb x 5 repetitions

Deadlift
- Earlier than: 285 lb x 5 repetitions
- After: 315 lb x 8 repetitions
This Reddit person additionally reported sustaining his outcomes concerning power post-cycle. When it comes to how LGD 4033 affected him, he reported feeling the happiest he has felt in a very long time. This report, mixed with our anecdotal experiences, suggests Ligandrol could also be a extremely efficacious SARM for psychological well-being.
The principle aspect impact he skilled was lethargy, occurring from week 5 and thereafter. Tiredness and fatigue are comparatively frequent on LGD 4033 and is usually a self-defense mechanism by the physique, trying to drive relaxation because of will increase in water retention and blood strain.
LGD 4033 Earlier than and After 8 Weeks

This Reddit person underwent an 8-week cycle of LGD 4033 with an unknown dosage. His outcomes are a mixture of muscle reminiscence and Ligandrol use, as he had not lifted weights for six months previous to his LGD 4033 cycle.
Weight achieve of 20 kilos may be anticipated when transitioning from sedentary to weight coaching. He seems to have gained 25–30 kilos; thus, nearly all of his outcomes are the byproduct of pure coaching, with 5–10 kilos probably being attributed to LGD 4033.
LGD 4033 Stacks
LGD 4033 and RAD 140 stack
A typical stack is to mix LGD 4033 with RAD 140, being two of probably the most potent SARMs for selling muscular power and hypertrophy. Though stacking LGD 4033 with RAD 140 might improve outcomes, it can additionally exacerbate unwanted side effects, notably:
- Liver values
- Ldl cholesterol
- Testosterone suppression
Pattern Cycle:
- RAD 140 (Testolone): 10 mg/day for 8 weeks.
- LGD 4033 (Ligandrol): 6 mg/day for 8 weeks.
Tapering the dosage as outlined beforehand in our LGD 4033 cycle part may also be carried out with this stack for LGD 4033. Though some customers might decide in opposition to doing so out of comfort.
If tapering, LGD 4033 can start at 4 mg/day for the primary 2 weeks and enhance to six mg/day from the third week onward. Larger dosages could also be utilized; nevertheless, this isn’t beneficial to keep away from extreme unwanted side effects.
LGD 4033 and MK-677 stack
LGD 4033 may be stacked with MK-677, in any other case often called Ibutamoren, a development hormone secretagogue. MK-677 will increase muscle hypertrophy and enhances subcutaneous fats loss with out exacerbating liver enzymes or levels of cholesterol.
This can be a fascinating stack for customers looking for notable fats loss when bulking, thereby enhancing muscle definition in addition to dimension.
Nonetheless, we discover MK-677 will increase water retention and visceral fats, making a extra bloated and protruding look to the midsection. Larger ranges of visceral fats storage are the results of MK-677’s destructive impact on insulin resistance.
Pattern Cycle:
- MK-677: 15 mg/day for 16 weeks.
- LGD 4033: 6 mg/day for 8 weeks.
MK-677 is slow-acting and thus requires ample time to peak development hormone (GH) ranges and have an effect on physique composition. A further good thing about this cycle is that MK-677 supplementation exceeds LGD 4033’s by 8 weeks, thus appearing as a type of post-cycle remedy in regard to sustaining an anabolic state upon Ligandrol cessation, serving to to cement outcomes.
LGD 4033, RAD 140, and MK-677 Stack: Earlier than and After Photos

This person revealed his transformation on Fb after stacking LGD 4033, RAD 140, and MK-677 collectively. He seen a big enhance in muscle hypertrophy, gaining roughly 10 kilos. Nonetheless, the addition of MK-677 led to a rise in visceral physique fats share, as evidenced by a wider waist.
Water retention and subcutaneous physique fats ranges additionally seem to have elevated barely, probably brought on by increased quantities of pure testosterone changing to estrogen. That is the byproduct of pure testosterone ceasing its binding to the androgen receptor.
Authorized LGD 4033 Various
LIGAN 4033 is our beneficial Ligandrol different. It replicates the muscle-building and strength-enhancing properties of LGD 4033, however with none undesirable unwanted side effects.
It’s FDA-approved and may be bought on-line and not using a prescription.
LIGAN 4033 is finest suited to weightlifters desirous to bulk up, rising muscle hypertrophy (dimension) and power. LIGAN 4033 will even hold physique fats at bay when consuming in a calorie surplus.
PCT for LGD 4033
In our testing, LGD 403 damages the HPTA. Thus, customers can make the most of PCT, much like steroid customers, to speed up the restoration of endogenous testosterone.
Analysis has proven that it could take virtually 2 months for testosterone ranges to return to regular from a small LGD 4033 dosage of 1 mg/day (7). We’ve discovered that administering Nolvadex or Clomid post-cycle can cut back this length by 50% (8).
Relying on the extent of suppression, if customers require aggressive PCT, Nolvadex is the stronger remedy in comparison with Clomid.
- 20 mg/day of Nolvadex, taken for 30 days is a standard protocol.
- If choosing Clomid, 25 mg/day is an efficient dosage, additionally taken for 30 days.
If customers will not be experiencing adversarial fluctuations in libido, sexual efficiency, power, and temper, then PCT could also be pointless.
LGD 4033 Half-Life
LGD 4033’s half-life is 24-36 hours (9). Thus, a PCT protocol ought to start roughly 8 days following the final dosage. It is because the elimination time is the same as 5.5 multiplied by the half-life.
How you can Take Liquid LGD 4033

There are two methods to manage LGD 4033 orally. Merely place it in your mouth, utilizing a syringe to measure the dosage, after which proceed to swallow.
Alternatively, it may be taken sublingually, bettering absorption and amplifying its results. This includes putting the liquid beneath the tongue and permitting it to sit down for 10–15 seconds previous to swallowing. Such placement permits contact with the mucus membrane, thus offering a extra direct route of entry into the bloodstream (10).
One dosage of LGD 4033 is enough every day. Our assessments present that taking it on a full or empty abdomen doesn’t have an effect on its organic availability.
LGD 4033 Opinions
In our Fb group, researchers have revealed the next LGD 4033 evaluations and anecdotes.
