What Is LGD 4033 (Ligandrol)?
LGD-4033, commonly known as Ligandrol, is a selective androgen receptor modulator (SARM) originally developed by Ligand Pharmaceuticals for treating muscle wasting conditions and osteoporosis. It selectively binds to androgen receptors in muscle and bone tissue while minimizing effects on other organs.

Side Effects and Management
Testosterone Suppression
The primary concern with LGD 4033:
- Dose-dependent suppression of natural testosterone
- At 10mg for 8 weeks: mild to moderate suppression common
- At 20mg or 12+ weeks: significant suppression likely
- Symptoms: Reduced libido, lower energy, mild mood changes
Management:
- Use lowest effective dose
- Limit cycle length to 8-10 weeks
- Consider PCT after cycle (especially 10mg+ or 8+ weeks)
- Blood work to assess actual suppression levels
Water Retention
Some users report mild water retention:
- Usually minimal (2-5 lbs)
- More common at higher doses
- Subsides after cycle completion
- Not fat gain—temporary intracellular water
Other Potential Side Effects
- Headaches: Usually mild and subside after first week
- Nausea: Rare; take with food if occurs
- Fatigue: Possible if suppression significant
- Elevated Liver Enzymes: Mild elevation possible; liver support recommended
What LGD Does NOT Cause
- No hair loss (DHT-related)
- No gynecomastia (doesn't aromatize)
- No acne (minimal androgenic activity)
- No prostate issues
- No significant cardiovascular stress
Post Cycle Therapy for LGD 4033

LGD 4033 vs. Other SARMs
LGD 4033 vs. MK 2866 (Ostarine):
- LGD: More powerful for bulking, more suppressive
- Ostarine: Milder, better for cutting/recomp, less suppression
LGD 4033 vs. RAD 140:
- LGD: Better for size gains, slightly less suppressive
- RAD 140: Better for strength, more aggressive cutting
LGD 4033 vs. S23:
- LGD: Milder, beginner-friendly, better for bulking
- S23: Very suppressive, closer to steroids, advanced only
Verdict: LGD 4033 offers the best balance of effectiveness and tolerability for muscle building, making it the top choice for first-time SARM users.
Frequently Asked Questions
Q: Can I use LGD 4033 as my first PED experience?
A: Yes, LGD 4033 is considered one of the best options for first-time users seeking muscle gains beyond natural limits. It's milder than steroids with fewer side effects, making it a good introduction to performance enhancement. Start with 5mg daily to assess tolerance before increasing to 10mg.
Q: How quickly will I see results from LGD 4033?
A: Strength increases typically appear within the first week. Noticeable muscle fullness and pumps by week 2. Visible size gains become apparent around weeks 3-4. Full results manifest by weeks 6-8. LGD is faster-acting than natural methods but not as rapid as some oral steroids.
Q: Will I keep my gains after stopping LGD 4033?
A: Most lean muscle gained can be retained post-cycle with proper PCT, training, and nutrition. Some water weight will be lost (2-5 lbs), and some strength may decrease as testosterone normalizes. However, the actual muscle tissue built is keepable. The key is not drastically cutting calories post-cycle and maintaining training intensity during PCT.
Q: Can women use LGD 4033?
A: Yes, but with caution. Women should use much lower doses (2.5-5mg daily maximum) due to higher sensitivity. LGD carries lower virilization risk than steroids but it's still possible at higher doses. Women should monitor for voice deepening, facial hair, or other masculinizing effects and discontinue immediately if they occur. Ostarine (MK-2866) is generally considered safer for women.
Q: Do I need a testosterone base with LGD 4033?
A: Unlike steroids, LGD doesn't require a testosterone base for most users. While it does suppress natural testosterone, it's usually mild enough that serious symptoms don't occur during an 8-10 week cycle. However, some advanced users do add low-dose testosterone (TRT dose) to prevent any suppression symptoms and potentially enhance results.
Q: Can LGD 4033 be detected in drug tests?
A: Yes. LGD-4033 is banned by WADA and most sporting organizations. It can be detected in urine tests for approximately 21 days after last dose, though detection windows vary. Athletes subject to testing should not use LGD or any SARMs. It's classified as a prohibited anabolic agent.
Q: What's better for bulking: LGD 4033 or steroids?
A: Steroids like testosterone or Dianabol will produce faster, more dramatic gains than LGD. However, LGD offers advantages: oral administration, no aromatization (no estrogen issues), less suppression than steroids, milder side effects, and more "keepable" gains. For natural lifters seeking moderate enhancement, LGD is excellent. For aggressive mass gain, steroids are more powerful. See our
steroids guide for comparison.
