SARM LGD-4033

What is Sarm LGD?

LGD-4033, known as Ligandrol, is a non-steroidal, oral selective androgen receptor modulator (SARM). Its high affinity for androgen receptors makes it one of the most effective SARMs on the market. Originally developed to reduce muscle loss in cancer patients during radiation and chemotherapy, Ligandrol is also used to treat other diseases and delay age-related muscle loss.

It was originally developed to reduce the muscle wasting that increases drastically in cancer patients as a result of radiation and chemotherapy. It was also used to combat the spread of muscle wasting in both acutely and chronically ill patients.
In addition to these two applications, it is also used in the United States to curb age-related muscle loss.

SARM LGD raises expectations by delivering the same therapeutic benefits as testosterone, but with improved safety and tolerability through its tissue-selective mechanism of action, and greater patient acceptance than conventional testosterone simply because it is marketed as a prohormone rather than an anabolic steroid. 

Origins and development

The development of Ligandrol, also known as LGD-4033, began in the early 2000s with the aim of creating a safe and effective treatment for people with muscle wasting, cachexia, hypogonadism, and osteoporosis. Originally developed by Ligand Pharmaceuticals, the drug received its name from this company. Ligandrol is a selective androgen receptor modulator (SARM) designed to produce an anabolic effect with minimal side effects compared with traditional anabolic steroids. In 2014, Viking Therapeutics acquired the licensing rights and advanced the research, bringing the SARM into Phase 2 clinical development. Despite promising results, Ligandrol is still in development and has not yet been approved as a medication.

Medical applications

LGD-4033 was initially developed to help cancer patients who lose muscle mass due to radiation and chemotherapy. Further research supports its suitability for delaying age-related muscle loss in the United States. Because of its ability to modulate androgen receptors in a tissue-selective manner, Ligandrol appears to be better tolerated and safer than conventional testosterone therapies. This selective action also makes it a promising approach to treating osteoporosis. Rat studies found that LGD-4033 improved muscle fiber cross-sectional area and capillarization, further underscoring its ability to increase muscle mass. These properties make Ligandrol a potentially valuable therapeutic option for various muscle and bone disorders.

Use in bodybuilding

In bodybuilding, LGD-4033, known as Ligandrol, has gained popularity because of its effectiveness in promoting rapid muscle growth and strength development. Bodybuilders typically take 10 to 20 milligrams daily for eight to twelve weeks. In addition to promoting muscle mass, Ligandrol also supports bone metabolism, increasing its appeal in the fitness world. However, using LGD-4033 also carries risks, particularly suppression of the body's own testosterone production. It is therefore advisable to undergo post-cycle therapy after a cycle. Studies show that even low doses can reduce total and free testosterone levels, so caution is required when using it. Although effective for building muscle, side effects such as water retention and a reduction in HDL cholesterol may occur, potentially increasing the risk of cardiovascular disease in the long term.

Effects of SARM LGD

Users of LGD-4033 show increased muscle activity, improved anti-resorptive and anabolic effects in the bones, as well as greater selectivity for muscle and bone over the prostate and sebaceous glands.

LGD-4033, also known as Ligandrol, is a selective androgen receptor modulator (SARM) distinguished by its strong binding to androgen receptors in skeletal muscle and bone. This property makes Ligandrol uniquely effective at building high-quality muscle mass and improving bone density. Its high oral bioavailability and tissue selectivity enable a targeted, tissue-specific effect that benefits muscle and bone tissue.
A Phase 1 study in healthy volunteers was recently completed.
This randomized, double-blind, placebo-controlled Phase I study found that doses of up to 22 mg per day could be taken without any significant side effects observed to date.

LGD-4033 has already undergone several different new studies. The results of these trials showed an increase in lean body mass and a reduction in body fat. Furthermore, users have reported improved well-being, increased strength, and better physical recovery.

Muscle mass and strength gains

LGD-4033 is known for its strong effects on muscle mass development and increases in muscle strength. As a selective androgen receptor modulator, Ligandrol directly stimulates protein synthesis in muscle cells, leading to rapid and effective muscle growth. Clinical studies have shown that even a low dose of 1 mg daily can increase lean body mass by around 1.2 kg in young men within three weeks. These results underscore the anabolic effect of Ligandrol, which can enable significant progress in muscle development without the typical side effects of anabolic steroids. Users also report significant improvements in strength and training performance, making Ligandrol particularly appealing to athletes and bodybuilders. Its selective binding to androgen receptors also minimizes the androgenic side effects commonly associated with conventional steroids.

Improved recovery

Another significant benefit of LGD-4033 is its ability to optimize the body's recovery phases. By promoting natural growth hormone secretion, Ligandrol not only maximizes muscle growth but also accelerates recovery after intense training. Phase I studies show that LGD-4033 may improve users' subjective sense of well-being, suggesting beneficial effects during recovery phases. Users report faster recovery times and increased muscle strength, which also contribute to more efficient fat loss. Taking Ligandrol once daily is sufficient to achieve these recovery benefits, making it a practical option for anyone seeking faster, more effective muscle recovery. Ligandrol thus appears to be a powerful means of improving recovery capacity and a useful tool in the pursuit of optimal fitness and muscle health.

So far, at least among the SARMs, LGD has produced the best results for muscle growth and overall weight gain. Muscle or mass gains depend heavily on the food supplied to the body.
When calorie intake is increased while using LGD, the body gains a considerable amount of mass within 8 weeks.

The difference from testosterone is that it is not a steroidal anabolic agent, but a prohormone that can provide substantial, targeted support for building lean muscle.
The liver toxicity of this orally administered SARM is considerably lower than that of the oral testosterone preparations available on the market to date. 

Side effects of Sarm LGD

Taking SARM LGD has not so far caused any noteworthy side effects or complications in users. To date, isolated cases of water retention, mild acne, or high blood pressure have been reported.
Nothing can yet be said about the long-term effects of regular use, given how new this SARM is. 

Testosterone suppression

Taking LGD-4033 can suppress the body's own testosterone production in a dose-dependent manner. Although clinical studies observed only mild suppression, it may be more pronounced in bodybuilding. Reports suggest that testosterone levels could fall from 650 to 450 nanograms per milliliter. A decline in total and free testosterone was apparent even at low doses in human studies. Fortunately, these levels return to baseline after discontinuing LGD-4033. Controlled laboratory studies found temporary testosterone suppression after taking Ligandrol, which is reversible after discontinuation.

Changes in cholesterol levels

Another observed effect of LGD-4033 is a change in cholesterol levels, particularly a decrease in HDL cholesterol. This molecule, known as “good” cholesterol, is essential for maintaining cardiovascular health. Studies have found that HDL levels fall as the dose of Ligandrol increases, potentially raising the risk of cardiovascular diseases such as heart attack and stroke. Fortunately, HDL cholesterol levels return to baseline after treatment is discontinued. This reduction in HDL cholesterol is described as a dose-dependent response, meaning it may be more pronounced at higher doses.

Need for PCT

Due to the testosterone suppression caused by taking LGD-4033, post-cycle therapy (PCT) is recommended after a cycle. In clinical studies, suppression of testosterone was minimal at low doses. However, it can be more pronounced at the higher doses commonly used in bodybuilding. PCT after a Ligandrol cycle helps restore hormonal balance and normalize the body's natural testosterone production. By minimizing potential complications caused by hormonal imbalance, planning PCT provides important protection and supports users' return to a healthy hormonal status.

Legal status of LGD-4033

LGD-4033, also known as Ligandrol, is regulated in Germany under the Anti-Doping Act (AntiDopG). Possession of Ligandrol in “non-small quantities” is prohibited. The Doping Substances Quantity Ordinance (DmMV) specifies this “non-small quantity” as 540 mg. Athletes should be aware that Ligandrol is on the World Anti-Doping Agency (WADA) list of prohibited substances and can be detected in doping tests.

Key points:

• Anti-Doping Act: Possession of Ligandrol in certain quantities is punishable by law.
• Doping Substances Quantity Ordinance: Sets the threshold for a “non-small quantity” at 540 mg.
• WADA ban: Ligandrol can be detected in doping tests.

Although LGD-4033 is not approved for human use, it can be purchased for research purposes in many countries.

The right dosage

To preserve physical integrity for as long as possible, the following should be observed when determining the dosage:

During the bulking phase, 5–10 mg can be taken daily over a total period of 8 weeks.
During a diet, the dose should be reduced to 3–5 mg daily.

To achieve the greatest possible fat loss, the product can be taken during this phase in combination with GW-501516 and S-4. Clinical studies have already shown significant effects at doses of just 1 mg per day. This underscores Ligandrol's potential strength and effectiveness.

LGD-4033 has a half-life of 24 to 36 hours, which means that a single dose per day is sufficient to maintain stable blood levels.

Benefits of LGD-4033

• Building high-quality muscle mass: Users report gaining up to 1.5 kilograms of lean muscle mass in just three weeks.
• No water retention or fat gain: Unlike anabolic steroids, Ligandrol does not cause unwanted water retention.
• Fast onset of effects: The first results appear after just 2 weeks!
