LGD 4033 (Ligandrol) is a potent SARM, usually utilized by weightlifters for bulking functions; resulting from its optimistic results on muscle energy and hypertrophy.
Ligandrol and different selective androgen receptor modulators present promise for the potential remedy of cachexia, resulting from its 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 described in 2007, being synthesized by Ligand Prescribed drugs (therefore its title ‘Ligandrol’) — an American biotechnology firm. Because of its latest formulation, the long-term results of LGD 4033 are presently unknown, with it being classed as a ‘analysis compound’ and but to obtain FDA approval.
Thus, LGD 4033 isn’t authorized for beauty functions (constructing muscle); nonetheless, it’s authorized for analysis functions i.e. administering it to your rat.
Though LGD 4033’s uncomfortable side effects usually are not but totally recognized, WADA has determined that its optimistic results on athletic efficiency are already apparent; therefore its ban on Ligandrol and different SARMs in skilled sports activities (1).
In section I scientific trials, LGD 4033 has produced notable will increase in lean muscle mass (2). One group of wholesome younger males got 1mg/day for 3 weeks and gained 1.21kg (2.67lbs). Contemplating the quick cycle, small dosage and there being no coaching stimulus to maximise muscle features — these are very optimistic outcomes.
Within the above-cited examine, the boys additionally recorded elevated leg press energy and energy on the stair-climber, earlier than and after the 3-week cycle. That is regardless of not often performing these particular workout routines all through the trial.
Weightlifters usually report making distinctive energy features on LGD 4033, even when in a calorie deficit.
Including 30+lbs to a squat or bench press 1RM is comparatively frequent after a cycle of LGD 4033, with its results on energy being superior to its capacity 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 chopping.
Authorized Steroid Options That Work
“There’s proof, when you might use these (steroid alternate options) they’d be significantly better than utilizing anabolic steroids”.
A number of of the herbs and amino acids, talked about by Dr. Thomas O’Connor, are current in Loopy Bulk’s authorized steroid alternate options.

Ligandrol Facet Results
Two delicate uncomfortable side effects related to LGD 4033 are complications and dry mouth. Nevertheless, extra troublesome uncomfortable side effects also can happen (as detailed under).
LGD 4033 has a considerably detrimental impact on HDL ldl cholesterol, with scientists observing an virtually 40% discount in simply 3 weeks, on the dosage of 1mg/day.
Beneficiant ranges of HDL ldl cholesterol cut back the chance of arteriosclerosis, bettering coronary heart well being. Thus, such sizeable reductions enhance the chance of myocardial infarction, much like the extent of oral anabolic steroids.
Such elevations in blood stress could also be attributed to LGD 4033 being administered orally and thus having to go by way of the liver. This could stimulate the enzyme, hepatic lipase, which causes such alterations in HDL ldl cholesterol.
The identical analysis recorded LDL ranges remaining steady; nonetheless, serum triglycerides decreased by virtually 15%, doubtlessly lowering some cardiovascular pressure.
SARMs, regardless of being non-steroidal, can nonetheless suppress pure testosterone ranges, resulting from aggressive binding to the androgen receptor. This consequently decreases LH (luteinizing hormone) and FSH (follicle-stimulating hormone).
LGD 4033 is probably the most potent SARM available on the market, thus it’s thought-about probably the most suppressive.
Within the beforehand cited trial that administered 1mg/day of Ligandrol; individuals’ complete testosterone declined by 50%. Free testosterone additionally skilled an identical 40% drop.
It took 56 days of drug cessation for the customers’ endogenous testosterone to return again to regular ranges.
Thus, contemplating customers generally take 5mg/day of LGD 4033 and upwards, testosterone suppression, on this case, is more likely to be extra extreme — indicating vital (but momentary) harm to the HPTA (hypothalamic-pituitary-testicular axis).
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 1mg/day, over 21 days (3).
Nevertheless, one analysis paper recorded a person creating jaundice after administering 10mg/day of LGD 4033 for two weeks. Thus, the hepatotoxicity of LGD 4033 is more likely to be intrinsic (dose-dependent).
Additional analysis exhibits that one other man (24 years previous), developed hepatocellular liver damage following LGD 4033-use (4). The dosage being utilized was not said, thus warning needs to be used when taking this SARM as additional analysis is required to determine the precise dosage inflicting such hepatotoxic results.
Water Retention & Gynecomastia
In idea, LGD 4033 mustn’t produce estrogenic uncomfortable side effects, because it doesn’t aromatize or immediately stimulate estrogen receptors.
Nevertheless, Ligandrol will compete with the physique’s pure testosterone for binding to the androgen receptor. LGD 4033’s larger affinity signifies that the physique’s pure testosterone loses this battle and as an alternative turns into extra obtainable for binding to different receptors — equivalent to estrogen.
Thus, LGD 4033 can not directly trigger larger estrogen ranges, growing the chance of potential bloating or/and gynecomastia.
Some LGD 4033 customers report shedding or recession of hair on the scalp, much like anabolic steroids. There are two the 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 (growing the physique’s pure stage of 5-alpha reductase).
DHT (Dihydrotestosterone) is the hormone liable for follicle miniaturization on the scalp, with extreme ranges inflicting androgenic alopecia.
One other potential explanation 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 (anagen) section, the typical hair loss naturally is 100 hairs a day.
Nevertheless, within the occasion of telogen effluvium i.e. sudden shocks or adjustments to the physique, this can lead to 30% of hair follicles coming into the remaining (telogen) section — during which case 300 hairs are misplaced every day.
Introducing SARMs into the physique can stimulate telogen effluvium, primarily tripling the extent of hair loss; nonetheless such shedding is often reversible post-cycle. Customers usually report hair thickening after simply 1-2 weeks of cycle cessation, after hormones regulate again to regular and hair follicles return to the anagen (rising) section.
LGD 4033 Dosage
A dosage has not been established by medical consultants right now, with LGD 4033 but to be FDA permitted. Nevertheless, in trials, 0.1, 0.3 and 1mg dosages have been generally used; with larger dosages yielding extra pronounced outcomes.
Male weightlifters taking LGD 4033 for physique-enhancing functions will usually take 2-10mg/day. Females will go for the decrease dosages on this vary (2mg/day), to stop the chance of virilization uncomfortable side effects occurring.
LGD 4033 is run as soon as per day. Dosages could also be tapered, guaranteeing consumer’s proceed making features in the course of their cycle. Thus, 1-2mg/day could also be a beginning dosage, with will increase of 1-2mg every week, till a desired most dosage is achieved. Some customers might not select to taper cycles out of comfort.
Notice: Though males can take as much as 10mg/day of LGD 4033, dosages in extra of 6mg/day usually produce minimal further features.

- Week 1: 1mg/day
- Week 2: 1mg/day
- Week 3: 2mg/day
- Week 4: 2mg/day
Notice: the upper the dosage and cycle period, the extra pronounced uncomfortable side effects will probably be for customers.
Authorized LGD 4033 Different
LIGABULK is our #1 rated authorized LGD 4033 product. It replicates the muscle-building and strength-enhancing properties of LGD 4033, however with none undesirable uncomfortable side effects.
It’s FDA-approved and may be bought on-line with no prescription.
LIGABULK is finest suited to weightlifters eager to bulk up, growing muscle hypertrophy (measurement) and energy. LIGABULK can even hold physique fats at bay when consuming in a calorie surplus.
LGD 4033 Outcomes – Earlier than and After Footage
This consumer carried out an 8-week LGD 4033 cycle, administering 5mg/day. He initially gained 13lbs, which dropped to 10lbs when water weight subsided post-cycle.
He admitted to consuming in an aggressive 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 greater arm measurement 3 weeks into his cycle (of whom had been unaware of his SARM-use).
Contemplating his high-calorie consumption, his outcomes when it comes to muscle hypertrophy from LGD 4033 are delicate.
Nevertheless, there was a dramatic distinction in muscular energy, with a earlier than and after log of his lifts under:
- Earlier than: 185lbs x 5 reps
- After: 205lbs x 8 reps
- Earlier than: 110lbs x 5 reps
- After: 125lbs x 6 reps
- Earlier than: 230lbs x 5 reps
- After: 255lbs x 8 reps
- Earlier than: 285lbs x 5 reps
- After: 315lbs x 8 reps
He additionally reported sustaining the above enhancements in energy post-cycle.
When it comes to how LGD 4033 affected him, he talked about that it made him really feel the happiest he’s been in a very long time. This, mixed with different anecdotal experiences, suggests Ligandrol could also be a extremely efficacious SARM for psychological well-being.
The principle aspect impact he skilled was lethargy, occurring at week 5 onwards. That is comparatively frequent on LGD 4033 and generally is a self-defence mechanism by the physique, making an attempt to pressure relaxation; resulting from will increase in water retention and blood stress.
LGD 4033 Earlier than and After #2
This consumer carried out an 8-week cycle at an unknown dosage. He had not lifted weights for six months previous to his LGD 4033 cycle, thus his outcomes are a mixture of earlier muscle mass being restored (through muscle reminiscence) and Ligandrol-use.
Weight achieve of 20lbs may be anticipated when transitioning from sedentary to weight coaching. He seems to have gained 25-30lbs, thus nearly all of his outcomes are the byproduct of pure coaching (with 5-10lbs doubtlessly being attributed to LGD 4033).
LGD 4033 Stacks
LGD 4033/RAD 140 stack
A standard stack is to mix LGD 4033 with RAD 140, with them being two of probably the most potent SARMs; equally selling muscular energy and hypertrophy (with minimal fats burning). Though stacking LGD 4033 with RAD 140 might improve outcomes, it’s going to additionally exacerbate uncomfortable side effects; significantly: liver values, ldl cholesterol and testosterone suppression.
- RAD 140 (Testolone): 10mg/day for 8 weeks
- LGD 4033 (Ligandrol): 6mg/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 towards doing so out of comfort.
If tapering, LGD 4033 can start on 4mg/day for the primary 2 weeks, then enhance to 6mg/day from the third week onwards. Larger dosages could also be utilized; nonetheless, this isn’t advisable (to keep away from extreme uncomfortable side effects).
LGD 4033/MK 677 stack
LGD 4033 may additionally be stacked with MK-677 (Ibutamoren), a progress hormone secretagogue. MK-677 will increase muscle measurement and subcutaneous fats loss; with out exacerbating liver enzymes or levels of cholesterol.
This can be a fascinating stack for customers eager to expertise notable fats loss when bulking, thus enhancing muscle definition — in addition to measurement.
Nevertheless, MK-677 can even enhance water retention (momentary) and visceral fats (everlasting), 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.
- MK 677: 15mg/day for 16 weeks.
- LGD 4033: 6mg/day for 8 weeks.
MK 677 is slow-acting and thus requires ample time to peak GH (progress hormone) ranges and have an effect on physique composition. An extra profit with this cycle is that MK 677 exceeds LGD 4033’s period by 8 weeks, thus appearing as a type of PCT, within the sense that it’s going to hold the physique in an anabolic state upon Ligandrol cessation; serving to to cement features.
LGD 4033/RAD 140/MK 677 Stack – Earlier than and After Footage
This consumer stacked LGD 4033, RAD 140 and MK 677 collectively concurrently.
He skilled a notable enhance in muscle hypertrophy (≤10lbs), though on the expense of a better visceral physique fats proportion (as a result of addition of MK-677) — signified by a bigger waist.
Water retention and subcutaneous physique fats ranges additionally seem to have elevated barely; doubtlessly brought on by larger quantities of pure testosterone changing to estrogen. That is the byproduct of pure testosterone ceasing its binding to the androgen receptor.
PCT for LGD 4033
As LGD 403 damages the HPTA (hypothalamic-pituitary-testicular axis), customers can make the most of a PCT (submit cycle remedy), much like steroid-users; serving to to speed up the restoration of endogenous testosterone.
Analysis has proven that it might probably take virtually 2 months for testosterone ranges to manage again to regular, from a small LGD 4033 dosage of 1mg/day; thus operating Nolvadex or Clomid post-cycle might be able to minimize this time in half.
Relying on the extent of suppression, if customers need an aggressive PCT, Nolvadex is the stronger medicine in comparison with Clomid.
20mg/day of Nolvadex, taken for 30 days is a standard protocol.
If choosing Clomid, 25mg/day is an efficient dosage — additionally taken for 30 days.
In case you are not experiencing opposed fluctuations in libido, sexual efficiency, power and temper — then a PCT will not be deemed needed.
LGD 4033 Half-Life
LGD 4033’s half-life is 24-36 hours, thus a PCT ought to start roughly 2-3 days after the final dosage.
How you can Take LGD 4033 (Liquid)?
There are two methods to manage LGD 4033 orally. Merely place it in your mouth, utilizing a syringe to measure out the dosage; after which proceed to swallow.
Alternatively, it may be taken sublingually, bettering absorption and thus amplifying its results. This includes putting the liquid beneath the tongue and letting it sit for 10-15 seconds previous to swallowing. Such placement allows contact with the mucus membrane, thus offering a extra direct route of entry into the bloodstream.
One dosage of LGD 4033 is enough every day. Taking it on a full or empty abdomen won’t have an effect on its organic availability.
LGD 4033 (Ligandrol) mg for mg is probably the most potent SARM available on the market. Its results on muscle mass are usually underwhelming compared to anabolic steroids. Nevertheless, its results on muscular energy are distinctive — with out producing extreme weight achieve.
Regardless of restricted analysis on LGD 4033, resulting from its latest formulation in 2007, there’s already sufficient proof to recommend it induces steroid-like uncomfortable side effects. Particularly being: testosterone suppression, ldl cholesterol alterations and potential liver toxicity.
