Bromantane vs MK-2866
Moderate Research vs Moderate Research
avoid Mechanism-based · 64% Both Bromantane and MK-2866 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 MK-2866
Weight 277.18 Da 389.33 Da
Half-life ~11 hours ~24 hours
Type Adamantane-bromophenyl derivative (C16H20BrN) Non-steroidal selective androgen receptor modulator (C19H14F3N3O3)
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
MK-2866
01 Increases lean body mass in a dose-dependent manner with clinical trial support
02 Preserves muscle mass during caloric deficit or catabolic conditions
03 Selective tissue activity reduces androgenic side effects compared to anabolic steroids
04 Oral bioavailability eliminates the need for injections
05 Does not aromatize to estrogen, avoiding gynecomastia and water retention
06 Improves physical function and stair-climbing power in clinical populations
07 Long 24-hour half-life allows convenient once-daily dosing
08 Mild side effect profile at commonly studied doses
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)
MK-2866
Mild testosterone suppression (dose-dependent, typically 10-30% reduction at 25 mg)
HDL cholesterol reduction (10-20% suppression observed in clinical trials)
Headaches, particularly during the first 1-2 weeks
Mild back pain or muscle cramps
Transient fatigue toward the end of longer cycles
Slight reduction in libido at higher doses or extended cycle lengths
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)
Active liver disease or significantly elevated liver enzymes
Hormone-sensitive cancers (breast, prostate) without oncologist clearance
Pregnancy or breastfeeding (potential endocrine disruption to fetus/infant)
Individuals under 21 years of age (risk of premature HPTA disruption during development)
Concurrent use of hepatotoxic medications without liver function monitoring
Known hypersensitivity to MK-2866 or any formulation excipients
Competitive athletes subject to WADA or USADA anti-doping testing
