Naltrexone vs Oxandrolone
FDA Approved vs Well Studied
avoid Mechanism-based · 64% Both Naltrexone and Oxandrolone 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
Naltrexone Oxandrolone
Weight 341.40 Da 306.44 Da
Half-life ~4 hours ~9-10 hours
Type Opioid antagonist (C20H23NO4) 17-alpha-alkylated anabolic-androgenic steroid (C19H30O3)
Key Benefits
Naltrexone
01 Broad anti-inflammatory and immunomodulatory effects via OGF-OGFr axis upregulation
02 Reduction in pro-inflammatory cytokines (TNF-alpha, IL-6, IL-12) through TLR4 antagonism
03 Compensatory upregulation of endogenous endorphins and enkephalins (200-300% increase)
04 Improved immune regulation and rebalancing of Th1/Th2/Th17 responses
05 Reduction in chronic pain through central and peripheral opioid system modulation
06 Potential improvement in mood, anhedonia, and overall well-being via endorphin enhancement
07 Extremely well-tolerated with minimal side effects at low doses
08 Low cost, especially as compounded LDN formulation
Oxandrolone
01 Promotes lean muscle mass gains with minimal water retention
02 Supports recovery of lost body weight following surgery, trauma, or chronic illness
03 Reduces bone pain associated with osteoporosis and improves bone mineral density
04 Does not aromatize to estrogen, avoiding estrogen-related side effects
05 Well-studied safety profile in women, children, and burn patients
06 Enhances nitrogen retention and protein synthesis during caloric deficit
07 Attenuates glucocorticoid-induced catabolism in post-surgical and burn patients
08 Lower androgenic potency compared to most oral anabolic steroids
Side Effects
Naltrexone
Vivid dreams or unusually intense dreaming - the most frequently reported side effect, typically diminishes over 1-2 weeks
Initial sleep disruption or insomnia during the first week of treatment
Mild nausea, particularly during the first few days
Transient headache during dose initiation or titration
Oxandrolone
HDL cholesterol suppression (dose-dependent, most significant lipid effect)
LDL cholesterol elevation
Mild hepatic stress (elevated liver enzymes ALT/AST)
Suppression of endogenous testosterone production
Mild headaches
Nausea or gastrointestinal discomfort
Changes in libido (increase or decrease depending on hormonal context)
Oily skin and mild acne
Contraindications
Current use of opioid medications or active opioid dependence (must be opioid-free 7-10 days minimum)
Acute hepatitis or severe hepatic impairment (primarily relevant at full dose)
Known hypersensitivity to naltrexone
Anticipated need for opioid pain medication (e.g., upcoming surgery - discontinue LDN 3-7 days prior)
Known or suspected prostate cancer
Breast cancer in males
Breast cancer with hypercalcemia in females
Pregnancy (Category X - known to cause fetal harm)
Nephrosis or nephrotic phase of nephritis
Hypercalcemia
Severe hepatic dysfunction or active liver disease
Hypersensitivity to oxandrolone or any formulation component
