Dihexa vs Tesofensine

Side-by-side comparison of key properties, dosing, and research.

Cognitive Enhancement
Dihexa
Fat Loss & Metabolic
Tesofensine
Summary
Dihexa is a potent experimental oligopeptide derived from angiotensin IV that dramatically enhances synaptogenesis. Preclinical research shows cognitive enhancement orders of magnitude more potent than BDNF — it is considered one of the most powerful nootropic compounds in research, but has very limited human safety data.
Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.

Key Benefits
  • Dramatically increases synapse formation (potentially 10 million× more potent than BDNF in animal models)
  • Enhances memory and learning
  • May reverse cognitive decline
  • Improves neuroplasticity and executive function
  • Long-lasting cognitive benefits from short courses
  • Potential therapeutic agent for Alzheimer's
  • Potent appetite suppression via triple monoamine reuptake inhibition
  • Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
  • Increases basal metabolic rate and energy expenditure
  • Reduces fat mass preferentially over lean mass
  • Potential cognitive benefit via dopaminergic and noradrenergic enhancement
  • Longer half-life than sibutramine allows once-daily dosing
Side Effects
  • Headache
  • Irritability
  • Brain fog during washout period
  • Unknown long-term effects (insufficient data)
  • Elevated heart rate and blood pressure (sympathomimetic)
  • Dry mouth
  • Insomnia and sleep disturbances
  • Nausea
