Dihexa vs Adamax

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

Cognitive Enhancement
Dihexa
Cognitive Enhancement
Adamax
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.
Adamax is a synthetic neuropeptide related to brain-derived neurotrophic factor (BDNF) signaling pathways. It is explored for cognitive enhancement, neuroprotection, and mood support, with proposed mechanisms involving TrkB receptor activation and enhancement of neuroplasticity similar to endogenous BDNF.

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
  • Proposed enhancement of learning and memory consolidation
  • Neuroprotective via BDNF-TrkB pathway support
  • May improve mood and resilience to stress
  • Potential support for neurogenesis
  • Cognitive clarity and focus enhancement (reported anecdotally)
  • Explored for neurodegeneration and age-related cognitive decline
Side Effects
  • Headache
  • Irritability
  • Brain fog during washout period
  • Unknown long-term effects (insufficient data)
  • Limited human safety data; largely anecdotal reports
