Palmitoyl Tetrapeptide-7Cognitive Enhancement
Adamax- Summary
- Palmitoyl Tetrapeptide-7 (Rigin) is a cosmetic peptide consisting of palmitic acid linked to the tetrapeptide sequence GQPR (Gly-Gln-Pro-Arg). It was designed to mimic the biological activity of the IgG immunoglobulin C-terminus, which downregulates the production of interleukin-6 (IL-6), a key driver of skin aging and inflammation.
- 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.
- Half-Life
- Topical penetration-dependent; effects last hours to days
- Estimated 1-3 hours (short; peptide degradation)
- Admin Route
- Topical
- Subcutaneous, Intranasal (research)
