Bromantane vs Oxandrolone
Moderate Research vs Well Studied
avoid Mechanism-based · 64% Both Bromantane 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
Bromantane Oxandrolone
Weight 277.18 Da 306.44 Da
Half-life ~11 hours ~9-10 hours
Type Adamantane-bromophenyl derivative (C16H20BrN) 17-alpha-alkylated anabolic-androgenic steroid (C19H30O3)
Key Benefits
Bromantane
01 Upregulates endogenous dopamine synthesis via tyrosine hydroxylase gene expression, producing sustained motivational drive without depletion
02 Anxiolytic properties reduce stress and anxiety without sedation, creating a state of calm, focused energy
03 Actoprotective effects improve both physical and mental performance under stressful or fatiguing conditions
04 Very low abuse and dependence potential due to the absence of acute monoamine release or reuptake inhibition
05 Minimal tolerance development compared to traditional stimulants, supporting longer-term use patterns
06 Smooth onset and offset with no crash or rebound effects
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
Bromantane
Insomnia or difficulty falling asleep (if taken too late in the day)
Mild anxiety or restlessness at higher doses (above 100 mg)
Mild headache (uncommon, typically transient)
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
Known hypersensitivity to bromantane or adamantane derivatives
Pregnancy and breastfeeding (insufficient safety data)
Severe hepatic impairment
Concurrent use of MAO inhibitors (theoretical risk of excessive dopaminergic activity)
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
