LGD-4033 vs Rosuvastatin
Moderate Research vs FDA Approved
avoid Mechanism-based · 64% Both LGD-4033 and Rosuvastatin carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.
Molecular Data
LGD-4033 Rosuvastatin
Weight 338.25 Da 481.54 Da
Half-life ~24-36 hours ~19 hours
Type Nonsteroidal selective androgen receptor modulator (C14H12F6N2O) Synthetic statin (C22H28FN3O6S-Ca)
Key Benefits
LGD-4033
01 Strongest SARM for lean muscle mass accrual, with clinical trial data supporting dose-dependent increases in lean body mass
02 Tissue-selective action with minimal stimulation of the prostate and other androgen-sensitive tissues
03 Clinical evidence of improved physical function (leg press strength, stair-climbing speed) in hip fracture patients
04 No aromatization to estrogen (no estrogen-related water retention or gynecomastia at the receptor level)
05 No conversion to DHT (reduced risk of androgenic hair loss and prostate stimulation compared to testosterone)
06 Convenient once-daily oral dosing due to 24-36 hour half-life
07 Phase 2 clinical data available, providing a stronger evidence base than most other SARMs
Rosuvastatin
01 Most potent statin available, with LDL reductions of 45-63% depending on dose
02 Long half-life (19 hours) allows flexible once-daily dosing at any time of day
03 Effective at counteracting AAS-induced lipid disturbances, particularly elevated LDL
04 Significant reduction in high-sensitivity CRP (30-50%), indicating anti-inflammatory benefit
05 Hydrophilic structure provides hepatic selectivity with potentially fewer muscle side effects
06 Raises HDL cholesterol by 8-14%, partially offsetting AAS-mediated HDL suppression
07 Proven cardiovascular event and mortality reduction in large-scale clinical trials
08 Reduces triglycerides by 10-35%, beneficial during bulking phases or when using compounds that elevate TG
Side Effects
LGD-4033
Testosterone suppression (dose-dependent; more suppressive than Ostarine at equivalent doses, occurs in most users by week 4-6)
Water retention (non-estrogenic mechanism, typically mild to moderate, contributes to scale weight increase)
HDL cholesterol reduction (dose-dependent lipid impact observed in clinical trials)
Headaches (most common in the first 1-2 weeks, usually transient)
Fatigue or lethargy (related to testosterone suppression, typically becomes noticeable mid-cycle)
Reduced libido (related to HPG axis suppression, severity varies by dose and individual)
Rosuvastatin
Muscle pain and myalgia (5-10% of users) -- the most frequently reported complaint, ranging from mild soreness to significant discomfort
Headache
Nausea and abdominal discomfort
Weakness or fatigue
Constipation or diarrhea
Contraindications
Pre-existing liver disease or elevated liver enzymes at baseline
Hormone-sensitive cancers (prostate cancer or other androgen-driven malignancies)
Pregnancy or potential pregnancy (teratogenic risk from androgen receptor agonism)
Breastfeeding
Age under 25 (incomplete endocrine system maturation and higher risk of HPG axis disruption)
Concurrent use of hepatotoxic medications without medical supervision
Known cardiovascular disease (insufficient long-term safety data for this population)
History of significant lipid abnormalities (LGD-4033 suppresses HDL)
Active liver disease or unexplained persistent elevations in hepatic transaminases
Known hypersensitivity to rosuvastatin or any excipients
Pregnancy and breastfeeding (Category X -- statins are teratogenic)
Concomitant use with cyclosporine (at all doses of rosuvastatin)
Severe renal impairment (eGFR <30 mL/min) for doses above 10 mg
