LGD-4033 (Ligandrol): A Comprehensive Guide
LGD-4033, commonly known as Ligandrol, is a type of Selective Androgen Receptor Modulator (SARM) that has gained significant attention in both the medical field and among athletes. This chemical compound is designed to mimic the activity of testosterone, specifically targeting androgen receptors in the body. Its primary appeal lies in its potential to enhance muscle strength and support muscle building without the severe side effects commonly associated with anabolic steroids.
What is LGD 4033 (Ligandrol)?
Ligandrol, also referred to by its code names VK5211 and Anabolicum, is a SARM developed to combat conditions like muscle wasting and weakness, often associated with aging and diseases such as cancer. Unlike anabolic steroids, which affect the entire body, LGD-4033 selectively binds to androgen receptors, primarily in muscle and bone tissues, promoting growth and strength.
Chemical Structure and Classification
LGD-4033 is classified as a non-steroidal SARM, meaning it differs chemically from steroids yet achieves similar anabolic effects. Its molecular structure allows it to bind to androgen receptors selectively, leading to muscle growth with potentially fewer health risks.
Medical Uses and Evidence of LGD 4033 (Ligandrol)
Therapeutic Applications and Research
- LGD-4033 has shown promise in treating conditions like sarcopenia and cancer cachexia.
- Research has explored its potential role in treating breast cancer.

Beginners are typically advised to start with a dosage of 5 mg per day. This dosage can be gradually increased to 10 mg per day based on individual response and goals. A typical cycle length is 8 to 12 weeks.
Can LGD 4033 be stacked with other SARMs or supplements?
Yes, LGD-4033 can be stacked with other SARMs such as Ostarine (MK-2866) or RAD-140 (Testolone) to enhance muscle-building effects. It can also be combined with supplements like creatine or protein powders to maximize results. However, stacking should be done cautiously to avoid potential side effects.
What are the most common side effects of LGD 4033?
Common side effects of LGD-4033 include suppression of natural testosterone production, fatigue, headaches, and mild hormonal imbalances. Post-cycle therapy (PCT) is often recommended to restore natural hormone levels after a cycle.
How does LGD 4033 compare to other SARMs like Ostarine or RAD-140?
LGD-4033 is often considered more potent than Ostarine (MK-2866) and RAD-140 (Testolone), making it a popular choice for those seeking substantial muscle gains. However, it may also carry a higher risk of side effects compared to other SARMs.
Is LGD 4033 legal in my country?
The legal status of LGD-4033 varies by country. In the United States, it is not approved for human consumption and is sold as a research chemical. In other countries, its sale and use may be similarly restricted. It is important to check local regulations before purchasing or using LGD-4033.
How does LGD 4033 affect testosterone levels?
LGD-4033 can suppress natural testosterone production, especially at higher dosages or longer cycles. This suppression can lead to hormonal imbalances, which is why post-cycle therapy (PCT) is recommended to help restore normal testosterone levels after use.
Can women use LGD 4033 safely?
While some women do use LGD-4033, it is important to do so with caution due to the potential for virilization effects, such as deepening of the voice or increased body hair. Lower dosages and shorter cycles may help mitigate these risks, but women should consult with a healthcare professional before use.
What should I do if I experience side effects while taking LGD 4033?
If you experience side effects while taking LGD-4033, it is advisable to reduce the dosage or discontinue use immediately. Consulting with a healthcare provider for further guidance, including possible post-cycle therapy, is also recommended.
Are there any known interactions between LGD 4033 and other medications?

How long does it take to see results with LGD 4033?
Most users begin to notice improvements in muscle mass and strength within the first few weeks of starting an LGD-4033 cycle. Optimal results are typically seen after 8 to 12 weeks of consistent use, combined with a proper diet and exercise regimen.
Is post-cycle therapy (PCT) necessary after using LGD 4033?
Yes, post-cycle therapy (PCT) is necessary after using LGD-4033 to help restore natural testosterone production and prevent long-term hormonal imbalances. PCT typically involves the use of SERMs (Selective Estrogen Receptor Modulators) like Nolvadex or Clomid.
Can LGD 4033 cause liver damage?
While LGD-4033 is not as hepatotoxic (liver-damaging) as traditional anabolic steroids, it is metabolized by the liver and may cause strain with prolonged use or high dosages. Regular liver function tests are recommended for users to monitor their health.
What should I look for when buying LGD 4033 to ensure quality?
When buying LGD-4033, look for products that come with third-party testing certificates, also known as Certificates of Analysis (COA), to verify purity and authenticity. Avoid products without proper labeling or those sold at suspiciously low prices.
Are there any studies or clinical trials that support the use of LGD 4033?
Yes, there have been several studies and clinical trials investigating the efficacy and safety of LGD-4033, particularly in increasing lean muscle mass and improving strength in patients with muscle-wasting conditions. However, it is still under investigation, and more research is needed to fully understand its long-term effects.
How should LGD 4033 be stored to maintain its effectiveness?
LGD-4033 should be stored in a cool, dry place, away from direct sunlight and moisture. It is recommended to keep it in its original container with the lid tightly closed to preserve its potency.
What are the potential risks of using LGD 4033 without medical supervision?
