DermorphinCognitive Enhancement
Dihexa- Summary
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- 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.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- Unknown (limited pharmacokinetic data)
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)
- Oral, SubQ, Topical
