Disclaimer: People ought to solely use SARMs for analysis functions, as they don’t seem to be FDA-approved and should have opposed results. Dr. Touliatos is offered 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 constructive results on muscle energy and hypertrophy (1).
Ligandrol and different SARMs present promise for the potential remedy of cachexia because of their anabolic results and tissue selectivity. LGD 4033 strongly binds to the androgen receptor, just like steroids. Nevertheless, it’s a weak agonist within the prostate.
Subsequently, the androgenic results of testosterone and different anabolic steroids is not going to happen with LGD 4033, stopping prostate hyperplasia.
LGD 4033 was created in 2007 and synthesized by Ligand Prescription drugs, therefore its identify, Ligandrol, an American biotechnology firm.
Because of its latest formulation, the long-term results of LGD 4033 are presently unknown, with it being categorized as a analysis compound and but to obtain FDA approval.
Thus, LGD 4033 is just not authorized for beauty functions. Nevertheless, it’s authorized for analysis functions; due to this fact, researchers could administer LGD-4033 to rodents.
Though LGD 4033’s uncomfortable side effects should not but absolutely recognized, the World Anti-Doping Company (WADA) has concluded that its constructive results on athletic efficiency are presently 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.” Nevertheless, 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 men and women looking for anabolic results, particularly of the youthful technology, are efficiently using LGD 4033 in the present day by way of muscle constructing.
In section 1 scientific trials, LGD 4033 has produced notable will increase in lean muscle mass. One group of wholesome younger males obtained 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 Energy
Within the above-cited research, the boys additionally recorded elevated leg press energy and energy on the stairclimber earlier than and after the 3-week cycle. That is regardless of not repeatedly performing these particular workouts all through the trial.
Our sufferers typically report distinctive energy outcomes on LGD 4033, even with lowered energy.
We discover that including 30 kilos or extra to squat and bench press workouts is comparatively widespread after a cycle of LGD 4033, with its results on energy being superior to its means so as to add lean muscle.
LGD 4033 doesn’t produce any notable fats loss, in contrast to Ostarine or Cardarine, making it extra optimum for bulking than chopping.

Ligandrol Aspect Results
In keeping with Affiliate Professor Nial Wheate, “2013 and 2018 human trials demonstrated the security of LGD 4033.” He additionally provides that LGD 4033 has “fewer uncomfortable side effects” compared to anabolic steroids. Regardless of preliminary success in scientific analysis, Wheate warns that LGD 4033 is “nonetheless experimental.”
Two delicate uncomfortable side effects we see with LGD 4033 are complications and a dry mouth. Nevertheless, extra troublesome uncomfortable side effects may also happen, comparable to:
- Ldl cholesterol alterations
- Testosterone suppression
- Liver toxicity
- Water retention and gynecomastia
- Male sample baldness
Ldl cholesterol
LGD 4033 has a considerably detrimental 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 improve the danger of myocardial infarction, just 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. Nevertheless, serum triglycerides decreased by nearly 15%, doubtlessly 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 now have discovered LGD 4033 to be essentially the most potent SARM in the marketplace and essentially the most suppressive. Within the beforehand cited trial that administered 1 mg/day of Ligandrol, contributors’ complete testosterone declined by 50%. Free testosterone additionally skilled an identical 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 more likely to be extra extreme, indicating vital short-term injury to the hypothalamic-pituitary-testicular axis (HPTA).
Dr. Thomas O’Connor says, “LGD 4033 customers are going to be quickly 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 danger 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).
Nevertheless, one analysis paper reported a person growing jaundice following 10 mg/day of LGD 4033 for two weeks. Thus, the hepatotoxicity degree of LGD 4033 is more likely to be dose-dependent, which helps what we have now discovered anecdotally.
Additional analysis reported a 24-year-old man with hepatocellular liver damage following 9 weeks of LGD 4033 use (6). The dosage being utilized was not acknowledged, so warning ought 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 uncomfortable side effects, because it doesn’t aromatize or instantly stimulate estrogen receptors.
Nevertheless, we see Ligandrol compete with pure testosterone when binding to the androgen receptor. LGD 4033’s larger affinity signifies that the physique’s pure testosterone concedes this twin and as a substitute is more and more out there for binding to different receptors, comparable to estrogen.
Thus, LGD 4033 can not directly trigger larger 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, just like anabolic steroids. There are two explanation why such hair loss is feasible, regardless of LGD 4033’s weak androgenicity. Just like how estrogen ranges can not directly rise from extra pure testosterone binding to different receptors, that is additionally how LGD 4033 can improve DHT ranges, elevating the physique’s pure degree of 5-alpha reductase.
Dihydrotestosterone (DHT) is the hormone accountable 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 section, common pure hair loss is 100 hairs a day. Nevertheless, within the occasion of telogen effluvium and sudden hormonal adjustments to the physique, 30% of hair follicles could enter the resting or telogen section. This situation ends in the each day lack of 300 hairs.
We discover that introducing SARMs to the physique can stimulate telogen effluvium, basically tripling the extent of hair loss. Nevertheless, such shedding is often reversible post-cycle. Our sufferers typically report hair thickening after 1–2 weeks following cycle cessation, with hormones regulating and hair follicles returning to the anagen or rising section.
LGD 4033 Dosage
A dosage has not been established by medical consultants presently, with LGD 4033 but to be FDA-approved. Nevertheless, in trials, 0.1, 0.3, and 1 mg dosages have been generally used, with larger 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 uncomfortable side effects occurring.
LGD 4033 is run as soon as per day. Dosages could also be tapered, making certain continued outcomes during 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 could not choose 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 ends in 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 uncomfortable side effects in customers.
LGD 4033 Outcomes: Earlier than and After Footage
This Reddit consumer 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 weight loss plan consisted of a beneficiant calorie surplus; thus, a few of this weight could 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 had been unaware of his SARM use. Contemplating his excessive calorie consumption, his outcomes by way of muscle hypertrophy from LGD 4033 might be thought of delicate. Nevertheless, there was a dramatic distinction in muscular energy, 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
- After: 255 lb x 8 repetitions
Deadlift
- Earlier than: 285 lb x 5 repetitions
- After: 315 lb x 8 repetitions
This Reddit consumer additionally reported sustaining his outcomes relating to energy 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 stories, suggests Ligandrol could also be a extremely efficacious SARM for psychological well-being.
The primary aspect impact he skilled was lethargy, occurring from week 5 and thereafter. Tiredness and fatigue are comparatively widespread on LGD 4033 and is usually a self-defense mechanism by the physique, making an attempt to power relaxation because of will increase in water retention and blood strain.
LGD 4033 Earlier than and After 8 Weeks
This Reddit consumer 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 acquire of 20 kilos could be anticipated when transitioning from sedentary to weight coaching. He seems to have gained 25–30 kilos; thus, the vast majority of his outcomes are the byproduct of pure coaching, with 5–10 kilos doubtlessly being attributed to LGD 4033.
LGD 4033 Stacks
LGD 4033 and RAD 140 stack
A standard stack is to mix LGD 4033 with RAD 140, being two of essentially the most potent SARMs for selling muscular energy and hypertrophy. Though stacking LGD 4033 with RAD 140 could improve outcomes, it can additionally exacerbate uncomfortable side effects, significantly:
- 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 can be carried out with this stack for LGD 4033. Though some customers could choose towards doing so out of comfort.
If tapering, LGD 4033 can start at 4 mg/day for the primary 2 weeks and improve to six mg/day from the third week onward. Larger dosages could also be utilized; nevertheless, this isn’t advisable to keep away from extreme uncomfortable side effects.
LGD 4033 and MK-677 stack
LGD 4033 may additionally be stacked with MK-677, in any other case referred to as 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.
Nevertheless, 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 detrimental 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. An extra advantage of this cycle is that MK-677 supplementation exceeds LGD 4033’s by 8 weeks, thus performing 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 Footage
This consumer revealed his transformation on Fb after stacking LGD 4033, RAD 140, and MK-677 collectively. He seen a major improve in muscle hypertrophy, gaining roughly 10 kilos. Nevertheless, 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, doubtlessly attributable to larger 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 advisable Ligandrol different. It replicates the muscle-building and strength-enhancing properties of LGD 4033, however with none undesirable uncomfortable side effects.
It’s FDA-approved and could be bought on-line with no prescription.
LIGAN 4033 is greatest fitted to weightlifters eager to bulk up, rising muscle hypertrophy (dimension) and energy. LIGAN 4033 may even maintain 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, just like steroid customers, to speed up the restoration of endogenous testosterone.
Analysis has proven that it will probably take nearly 2 months for testosterone ranges to return to regular from a small LGD 4033 dosage of 1 mg/day (7). We now have discovered that administering Nolvadex or Clomid post-cycle can cut back this period by 50% (8).
Relying on the extent of suppression, if customers require aggressive PCT, Nolvadex is the stronger treatment in comparison with Clomid.
- 20 mg/day of Nolvadex, taken for 30 days is a typical protocol.
- If choosing Clomid, 25 mg/day is an efficient dosage, additionally taken for 30 days.
If customers should not experiencing opposed 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 one 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 inserting the liquid beneath the tongue and permitting it to take a seat for 10–15 seconds previous to swallowing. Such placement permits contact with the mucous membrane, thus offering a extra direct route of entry into the bloodstream (10).
One dosage of LGD 4033 is adequate every day. Our exams present that taking it on a full or empty abdomen doesn’t have an effect on its organic availability.
LGD 4033 Critiques
In our Fb group, researchers have revealed the next LGD 4033 evaluations and anecdotes.
I haven’t been within the fitness center since November because of well being points. I took a dose of LGD 4033, and my lats are so pumped they really feel like they’re going to tear proper off my physique. No pre-workout or something, simply LGD.
LGD 4033 is ace stuff. I took a 9-week course, and I placed on some respectable dimension and weight. I used to be lifting much more than regular. It takes a bit of time to kick in.
I’ve been on LGD for two weeks, not likely noticing something but, however I had per week off because of being not effectively. Hopefully it can kick on this week.
LGD 4033 is a good compound. That’s what my first cycle was with MK-2866. I began LGD 5 mg for two weeks and ostarine 15 mg, then I bumped it to 10 mg LGD and 25 mg MK-2866. Nice outcomes.
I’ve a problem with gyno. I did a really suppressive cycle of LGD 4033, RAD 140, and YK-11. Within the 4th week I skilled a gyno flare-up, so I had blood work finished, and my estrogen was 80 pg/ml, so I used exemestane, and estrogen went right down to a standard degree.
LGD 4033 vs. LGD 3033
The official and proper medical identify is LGD 3303. Nevertheless, it’s extra generally referred to as LGD 3033.
Some mistakenly consider that LGD 3033 and LGD 4033 are related compounds structurally, as they’ve nearly an identical names. Nevertheless, Ligand Prescription drugs, the identical firm that based them, is accountable for their related names.
In follow, we see LGD 3033 having contrasting results to LGD 4033, with the previous producing dry muscle good points with none extra water retention. On this respect, LGD 3033 is extra just like YK-11, demonstrating enhanced anabolic results and elevated toxicity than LGD 4033.
- We generally observe distinctive will increase in muscular energy from sufferers taking LGD 3033, that are extra pronounced than LGD 4033.
- LGD 3033 additionally possesses a brief half-life of 6 hours, in comparison with LGD 4033’s 24-36 hours; thus, extra frequent dosing is required to maintain peak concentrations. On this state of affairs, administering LGD 3033 twice a day is extra possible than administering LGD 4033 as soon as a day.
- LGD 3033, nevertheless, will produce extra notable uncomfortable side effects as a consequence of its elevated anabolism. We noticed a 60% discount in complete testosterone in a single affected person following a 6-week LGD 3033 cycle. Consequently, it’s the most suppressive SARM we have now come throughout primarily based on our exams.
One among our sufferers was significantly impressed with LGD 3033, likening it to a reasonably dosed testosterone and Anavar cycle that he had beforehand utilized. He talked about that, regardless of “his weight loss plan being off,” he displayed distinctive muscle hypertrophy and energy. This affected person took 20 mg/day of LGD 3033, consuming 10 mg twice each day, 12 hours aside.
We now have additionally discovered that sufferers vulnerable to hair loss on SARMs comparable to RAD 140 could reply extra favorably to LGD 3033, which seems to protect hair follicular well being even in larger doses.
LGD 3033 reveals stronger androgenic results in comparison with different SARMs in regard to distinguished trapezius and deltoid development. We discover sufferers additionally expertise extra frequent incidences of zits vulgaris from LGD 3033 because of elevated sebum manufacturing. Nevertheless, in analysis, we see LGD 3033 being an agonist of the prostate, indicating a scarcity of androgenicity on this area and profitable tissue selectivity (11).
In our expertise, researchers typically report on the results of LGD 4033 congruously, whereas stories on LGD 3033 are extremely conflicting, with some reporting minimal results and others experiencing distinctive outcomes. That is possible as a result of larger prevalence of counterfeit LGD 3033 merchandise in comparison with LGD 4033. Subsequently, it is very important purchase LGD 3033 from a reliable SARM firm that provides certificates of study to show authenticity and purity.
LGD 4033 is understood to be a milder SARM in comparison with LGD 3033; nevertheless, this is because of researchers administering roughly 3 occasions larger doses of LGD 3033. We generally see researchers administer 20 mg/day of LGD 3033 and solely 6 mg/day of LGD 4033. Thus, LGD 4033 is definitely the stronger SARM on a milligram foundation.
Abstract
LGD 4033, or Ligandrol, on a milligram foundation is essentially the most potent SARM in the marketplace. Its results on muscle mass are typically underwhelming compared to anabolic steroids. Nevertheless, its results on muscular energy are distinctive, with out producing extreme weight acquire.
Regardless of restricted analysis on LGD 4033, because of its latest formulation in 2007, we have already got adequate proof to recommend it induces steroid-like uncomfortable side effects, particularly:
- Testosterone suppression
- Сholesterol alterations
- Potential liver toxicity
